WEIMI / MECHANICAL PROCUREMENT
The holes align.
What are they designed to hold?
Separate accessory holes from the approved structural mounting interface before ordering.
01 / ASSEMBLY EVIDENCE
Introduction
The replacement display is the right size, and a bracket lines up with four holes on its rear housing. That is useful evidence of geometry. It is not yet evidence that those holes are intended to carry the display. An accessory attachment can look like a familiar mounting pattern while serving a different mechanical purpose.
This guide helps vending equipment buyers qualify that distinction before approving a screen substitution. It uses a public Elo support article reviewed on 15 October 2026 as a documented example. The example applies to the named Elo 22-inch I-Series for Android, not to a verified component inside a WEIMI machine. No WEIMI mounting pattern, fastener specification or load rating is established here.
The purchasing decision is whether the supplier has identified an approved replacement assembly. Hole spacing is one input to that decision. The intended function of the holes, the supported bracket arrangement and responsibility for the completed installation must also be clear.

Quick Answer
Do not approve a replacement display solely because the holes align. Ask the responsible equipment supplier to identify which interface supports the complete device and which attachment points are reserved for accessories. Obtain the current drawing or installation document for the exact display and mounting assembly.
Elo’s cited article identifies two rear patterns on its 22-inch I-Series for Android. The outer 100 × 100 mm pattern is the primary structural interface. The inner 75 × 75 mm inserts secure an optional PoE adapter module and must not support the full unit. These are model-specific instructions. They do not mean every 75 mm mounting interface is unsuitable, nor do they establish the arrangement used by WEIMI.
Where the proposed part differs from the original, request written supplier confirmation before ordering or installation. A photograph showing aligned holes cannot replace that confirmation.

Comparison Table
| Evidence presented | What it establishes | What still needs confirmation |
|---|---|---|
| Matching hole spacing | A geometric relationship between holes and bracket | Whether those holes carry the whole device |
| Accessory attachment identified | A defined purpose for a module or peripheral | Whether a separate structural interface exists |
| Approved mounting drawing | The documented assembly for a named configuration | Whether the supplied revision and parts match it |
| Supplier acceptance record | Who reviewed the actual replacement proposal | Whether installation and service responsibilities are assigned |
Use this distinction when evaluating quotations. An offer can be complete on dimensions while remaining incomplete on mechanical authorization. Keep the missing approval visible instead of allowing a parts description such as “compatible bracket” to close the issue by implication.

Who Should Buy This
This review is useful for service organizations buying replacement displays, distributors qualifying alternative components and operators comparing equipment proposals with different display assemblies. It is especially relevant when the monitor and bracket come from separate suppliers.
It also helps procurement teams receiving photographs instead of controlled mechanical documents. A seller may accurately report the spacing it measured while lacking authority to approve the assembled installation. Ask who supplies the display, who specifies the supporting assembly and who accepts the combination for the ordered cabinet.
Buyers selecting a complete machine should raise these questions during spare-parts planning. An approved replacement assembly can be easier to manage than separately sourced parts whose compatibility remains unresolved. This article makes no claim that either purchasing route is always cheaper.

How We Evaluate Smart Vending Machines
The WEIMI products below are a procurement shortlist based on public listings, not independent mechanical tests. We have not dismantled these machines, inspected mounting inserts, measured structural loads or installed replacement displays. Their public merchandising features support an initial format discussion; they do not prove component interchangeability.
For this topic, evaluation focuses on the support evidence attached to the proposed configuration. Can the supplier identify the complete display assembly? Does the document distinguish accessory attachments from structural support? Does the replacement proposal retain an approved arrangement or require an engineering review?
We keep a clear boundary between a machine’s advertised customer features and its service documentation. A touchscreen listing does not establish a particular VESA pattern. A visible payment area does not identify the display manufacturer. Those details must come from the supplier responsible for the actual order.

Key Buying Factors
Hole function before hole spacing. Ask the supplier to label the purpose of each relevant attachment point. The Elo example shows why two familiar patterns on one housing can have different permissions. A pattern’s appearance alone cannot identify the intended load path.
Exact device and revision. Record the supplier’s display part reference and the revision covered by its documentation. Do not transfer approval from a similar screen size, an earlier cabinet or a visually comparable replacement. Keep the quotation and the proposed drawing tied to the same configuration.
Complete supporting assembly. Request the approved relationship between display, bracket and cabinet. A bracket’s standalone description does not establish that the display housing or cabinet attachment is suitable. Let the responsible supplier or qualified installer resolve the complete arrangement.
Fasteners specified by the actual provider. Obtain the required fastener details from the current installation instructions. This article supplies no screw length, torque, engagement depth or allowable load for WEIMI. Do not derive a substitute specification from the external Elo example or from a generic online diagram.
Accessory clearance and service access. Ask whether an added adapter, cable or peripheral changes the approved assembly or prevents required access. The presence of unused holes does not authorize attaching another item. Have the provider assess the proposed configuration as supplied.
Change authorization. If the original bracket is unavailable, request an explicit replacement proposal. Record whether the supplier approves the substituted display and support assembly together. A purchasing note saying “same dimensions” leaves the central mechanical question unanswered.
Installation responsibility. Identify who is qualified and authorized to perform the work and which instructions apply. Do not ask site staff to discover compatibility by suspending the device from an unverified pattern. Procurement review should settle the evidence gap before physical work starts.

Best Smart Vending Machines
These three real WEIMI listings offer different retail formats to discuss with the supplier. They are not ranked by mounting performance. No shared display, bracket, hole pattern or spare part is inferred between them.
WM22 touchscreen snacks and drinks vending machine
The WM22 listing presents a 21.5-inch touchscreen, multi-item purchasing and promotional functions. It is a relevant shortlist candidate when the buyer wants to discuss a screen-based selection experience. For replacement planning, request the approved display assembly and its service reference. The advertised screen size does not prove a mounting interface.
Single-door AI vending fridge
The single-door AI fridge listing describes an open-select-close retail flow with camera recognition and cloud functions for packaged products. It is not treated here as a juice squeezing machine. Ask which customer interface is included in the quoted configuration and how its supporting assembly is documented. No recognition accuracy guarantee or display manufacturer is inferred.
Dual-cabinet vending machine
The dual-cabinet listing shows a main and secondary cabinet arrangement with visible spiral merchandising and a payment area. It can enter a format discussion where the buyer wants to evaluate that arrangement. Request cabinet-specific service documentation. The appearance of the payment area does not prove that a display or bracket can move between the two cabinets.
08 / ASSEMBLY EVIDENCE
Feature Comparison
| Public shortlist | Listing-based discussion | Mechanical evidence to request |
|---|---|---|
| WM22 touchscreen machine | Screen-based selection, promotions and multi-item purchasing | Exact approved display and supporting assembly |
| Single-door AI fridge | Packaged-product open-select-close operation | Quoted customer interface and its mounting documentation |
| Dual-cabinet machine | Main and secondary cabinet merchandising format | Assembly references and service access for the quoted cabinets |
A productive supplier response separates confirmed listing features from configuration-dependent service details. Ask for a part reference or drawing where mechanical approval matters. Do not convert a blank answer into an assumption that all three formats use the same components.

Cost & ROI Analysis
Evaluate the cost of obtaining a complete, reviewable proposal before comparing replacement part prices. The following administrative example is entirely fictional. It is not a WEIMI quotation, a prediction of repair savings or a calculation of structural risk.
| Assumed review activity | Fictional input | Illustrative amount |
|---|---|---|
| Match part references to the drawing | 45 minutes at $40 per hour | $30 |
| Supplier clarification meeting | 30 minutes at $40 per hour | $20 |
| Update the approved parts record | 15 minutes at $40 per hour | $10 |
| Total review effort | 90 minutes at the assumed rate | $60 |
The arithmetic is $40 × 1.5 hours = $60. Actual engineering review, installation, freight, parts and downtime are excluded and require separate estimates. Do not describe this review cost as money saved: there is no measured avoided expense in this example.
If one offer includes an approved assembly and another sells only a screen, compare their complete scope. Record any missing bracket, documentation, review or installation responsibility before calculating a purchasing difference. A lower component price alone does not establish better return on investment.

Best Choice by Scenario
Replacing an identical documented assembly: ask the supplier to confirm the supplied revision and parts match the approved configuration. Keep the current documentation with the service order rather than relying on memory of the previous installation.
Introducing a different display: require the responsible provider to review the proposed support assembly before purchase approval. Treat matching screen size and hole spacing as preliminary information.
Adding a peripheral behind the screen: ask which accessory attachment points are authorized and whether the addition changes clearances or service access. Do not repurpose holes that have a different documented function.
Buying a complete new cabinet: request the relevant assembly and spare-parts information as part of the support discussion. Select the retail format for the intended operation, then resolve its actual mechanical configuration with the supplier.

Applications
A distributor can add a “mounting function” field to its parts comparison record. The field should cite the supplier’s document rather than merely list measured spacing. This makes it harder for an accessory attachment to be mistaken for a structural interface during a later substitution.
A service manager can require each replacement proposal to identify the display reference, approved supporting assembly, document revision and responsible installer. If the supplier changes a part, reopen the affected approval instead of silently carrying forward the earlier record.
An operator placing repeat orders can ask whether display assemblies have changed between production configurations. Similar cabinet photographs do not establish identical internal hardware. Keep the supplier’s answer tied to the machines covered by the service plan.
These are suggested procurement practices. No completed WEIMI installation, customer incident or measured reduction in failures is claimed.

FAQ
Does a matching VESA pattern prove the assembly is approved?
No. It identifies geometry, while the device’s documented mechanical function and the complete supporting assembly still require confirmation from the responsible provider.
Are all 75 × 75 mm mounting patterns unsuitable?
No. The restriction cited here belongs to the named Elo 22-inch I-Series for Android, where the inner pattern is assigned to an optional PoE module. Do not generalize it to other products.
Does this mean WEIMI uses the Elo display in the example?
No. The external support article supplies a clear example of differing hole functions. No Elo display or mounting arrangement has been verified inside the shortlisted WEIMI machines.
Can I choose screw length from the hole spacing?
This article provides no such rule. Ask for the actual supplier’s current fastener and assembly instructions for the exact configuration, and have the work handled by the responsible qualified provider.
Does a bracket rating settle every mechanical question?
No. Request approval for the combination of display, bracket and cabinet attachment. A standalone bracket description does not establish the suitability of every other part in that combination.
Is the $60 example a replacement price or promised saving?
No. It is a fictional administrative review calculation using an assumed hourly rate. Parts, engineering, installation and downtime are outside that example.
13 / ASSEMBLY EVIDENCE
Final Recommendation
Approve the replacement around a documented assembly, not a photograph of matching holes. The supplier should identify the intended structural interface, distinguish accessory attachments and confirm the proposed configuration using current documentation.
The Elo example makes the distinction concrete: two rear patterns on one named device serve different mechanical purposes. Use that lesson to ask better procurement questions. Keep its dimensions and restrictions within their documented product scope.
Choose the vending format that fits the retail operation, then qualify its actual display assembly and service support. No shortlist item is declared mechanically superior on the evidence available here.

CTA
Request a WEIMI configuration and replacement-parts discussion. Share the machine reference and the supplier part information for the proposed display. Ask for the approved assembly reference, installation responsibility and any unresolved substitution review before placing the order.
