WEIMI / CUSTOMER ROUTE GEOMETRY
Narrow slots.
Which direction?
Opening size + slot axis + actual customer route.
Introduction
A vending location looks ready: the cabinet fits, the payment position is clear and the customer path crosses an existing floor grate. The review records the grate’s width but overlooks the direction of its elongated openings. A narrow opening and a suitable orientation are different pieces of evidence.
The U.S. Access Board explains that wider floor openings can catch wheelchair casters and that elongated openings need a relationship to the dominant direction of travel. For a vending project, this means the equipment layout and customer route should be reviewed together with the existing surface geometry.
This article addresses customer approach over floor openings. It does not assess drainage performance, structural loading or the route used to move a loaded cabinet. Three WEIMI public listings form a retail shortlist; no product or installation is certified, and no physical site measurement was performed.
Quick Answer
The Access Board’s floor-surfaces guide describes openings limited to prevent passage of a half-inch-diameter sphere. It says elongated openings must have their long dimension perpendicular to the dominant travel direction. Where no dominant flow exists, the guide limits openings to half an inch in both dimensions. It also describes a complete accessible bypass condition under which orientation can be in either direction.
These are scoped U.S. provisions to discuss with the responsible site reviewer. Do not convert the bypass statement into permission for any inconvenient detour or apply the dimensions as a worldwide rule. Confirm applicability, actual geometry and other route requirements before approving the location.
Comparison Table
| Site condition | Evidence needed | Mistake to avoid |
|---|---|---|
| Elongated slots with a dominant crossing direction | Opening geometry and a plan marking the actual travel direction. | Measuring only the short slot dimension. |
| People approach from several directions | A documented review of whether there is a dominant flow pattern. | Choosing a convenient arrow without observing the layout. |
| A proposed route around the grate | Evidence that an accessible route completely bypasses the openings. | Calling any narrow gap or partial avoidance a complete bypass. |
| New cabinet orientation | Updated customer-use layout and relationship to the grate. | Reusing a review based on the previous position. |
| Replacement grate | Exact product and installed opening arrangement. | Assuming the new grate matches the removed one. |
A floor photograph can support the record, but it does not replace dimensions or the reviewer’s interpretation of the actual route.
Who Should Buy This
Use this brief when placing vending equipment near an existing grate, channel cover or other floor opening on the intended customer approach. It is useful for facilities buyers, distributors collecting site information and operators changing a cabinet’s orientation.
Include the person responsible for the site’s access review and the party responsible for the grate. The vending supplier needs to describe the customer-use arrangement; the building team needs to provide the surface and route evidence. Neither should infer the other’s measurements from a sales rendering.
The question can arise indoors or outdoors, but the applicable rules and environmental considerations remain project-specific. Outside the United States, obtain local requirements rather than treating this guide as a substitute for them.
How We Evaluate Smart Vending Machines
We compare three real public WEIMI retail descriptions and use the official Access Board guide to frame the floor-opening question. This is a public-listing procurement shortlist, not an independent caster test, a drainage study or an accessibility assessment.
Draw the journey before choosing the arrow
Mark how a customer reaches selection or payment, moves to retrieval and leaves. Identify the floor opening’s location and orientation on the same plan. The dominant travel direction should be a site-review conclusion, not a label selected merely to make an existing grate appear suitable.
Separate measured geometry from interpretation
Obtain the dimensions of the actual installed openings using an appropriate competent process. Record which opening, location and drawing revision the evidence covers. The reviewer then interprets the measurements under applicable requirements. A cabinet dimension does not establish a grate dimension.
Use a review record rather than a risky demonstration
Do not ask a customer to roll a mobility aid over a suspected unsuitable opening to prove a point. Have the responsible professionals select the appropriate assessment. This article provides no live trial result and recommends no improvised alteration of the grate.
Key Buying Factors
The long and short axes both matter
An elongated slot has two dimensions and an orientation. Under the cited guide, its relation to the dominant travel direction matters even where its narrow dimension is within the stated limit. Keep the drawing clear enough to distinguish the slot’s long axis from the grate panel’s overall length.
No dominant flow is a separate case
The Access Board explains that, without a dominant travel pattern, openings must be limited in both dimensions. A vending area with several possible approaches needs a genuine layout review. Do not assume that the direction facing the screen is the only direction in which people cross the floor surface.
A complete bypass needs evidence
The guide allows any orientation where an accessible route can completely bypass the openings. Ask the reviewer to identify that route and confirm the relevant conditions. A partial route that still crosses one end of the grate is not evidence of complete avoidance. Other route requirements remain part of the wider assessment.
An equipment move can change the relationship
Rotating a cabinet can change where customers stand and the direction they travel. The grate may remain unchanged while the earlier review no longer describes the layout. Treat location and orientation changes as triggers to check the record again.
A replacement component needs its own identity
Maintenance may replace a grate with a visually similar item. Keep the actual component specification and installed condition linked to the location. Similar panel size does not prove identical opening geometry or orientation.
Keep other surface questions separate
Slip resistance, surface stability, changes in level and structural suitability need their own evidence where relevant. A favorable slot-orientation review does not establish them. Likewise, a slip-resistance rating does not determine whether a caster can enter an opening.
Best Smart Vending Machines
1. WEIMI WM22 touchscreen snacks and drinks machine
The WM22 public listing describes a 21.5-inch touchscreen, multi-item purchases and possible merchandise-channel arrangements. It is a candidate for packaged selection-and-dispense retail. Ask the supplier to identify the actual selection, payment and pickup positions for the quoted configuration.
Map those positions against the existing grate. Do not infer a single straight customer path merely because the screen is centered in a product image. The public listing contains no measured floor-opening result or approval of a particular site.
2. WEIMI single-door AI retail fridge
The single-door AI fridge listing describes direct open, select and close shopping with camera recognition and cloud management for suitable packaged products. It is not a juice-preparation machine. Identify the actual customer access and payment arrangement before assessing the approach.
Keep door movement and the floor-opening review separate but coordinated. An open-selection format does not establish where every customer will travel, and camera recognition does not provide site-access evidence. Request the actual layout and have the building team review it.
3. WEIMI dual-cabinet vending machine
The dual-cabinet public listing shows main and secondary cabinets with spiral merchandise channels and a payment area. It is a candidate for a broader packaged assortment. Review the customer-use area for the complete arrangement rather than only the main cabinet.
Where the proposed assembly changes the routes through a room, document that relationship explicitly. Do not assume the second cabinet has no effect on circulation. No opening dimensions, dominant travel pattern or accessible bypass are established by the public listing.
Feature Comparison
| Retail format | Customer-route question | Evidence still required |
|---|---|---|
| WM22 touchscreen | How do selection, payment and pickup positions connect? | Actual route in relation to grate geometry. |
| Single-door AI fridge | How does the actual access arrangement affect approach? | Coordinated layout and site interpretation. |
| Dual-cabinet assembly | Does the full arrangement alter paths across the surface? | Complete installed plan and review of any bypass. |
These are buying questions rather than performance ratings. The suitable machine depends on the assortment and site, while the grate review depends on the installed route and surface.
Cost & ROI Analysis
Plan the work needed to obtain a usable layout and surface record. No verified incident reduction, financial return or equipment payback is available from this comparison. Obtain actual quotations for any professional review or site work.
| Fictional planning input | Calculation | Boundary |
|---|---|---|
| Prepare layout 25 minutes; coordinate surface information 20 minutes; update record 15 minutes | 60 minutes total | Illustrative internal coordination only. |
| Assumed staff rate US$29/hour | 60 ÷ 60 × US$29 = US$29 | Hypothetical labor cost. |
| Assumed later layout revision 15 minutes | 15 ÷ 60 × US$29 = US$7.25 | Sensitivity example, not a change quotation. |
All durations and rates are assumptions. They exclude site surveying, professional fees, grate replacement, drainage work, construction and interruption. They do not price risk or imply that moving a cabinet is an approved remedy.
Keep a proposed change conditional until the responsible reviewers confirm its wider effects. A lower coordination cost does not justify a route that has not been assessed. Record the actual scope and obtain the appropriate design before committing to site work.
Best Choice by Scenario
One clear direction crosses elongated slots
Document the direction and the slot axes together. Ask the reviewer to assess the relationship under the applicable provisions. Do not accept a drawing showing only the overall grate rectangle.
Several approaches converge at the vending area
Ask whether a dominant travel pattern exists. If it does not, the cited guide treats both opening dimensions as relevant. Preserve that decision rather than selecting one favored approach to simplify the paperwork.
A route is proposed around the openings
Require evidence of a complete accessible bypass and review the rest of that route. Do not ask customers to infer a detour from cabinet placement alone. Any signage or layout changes need their own appropriate review.
The vending layout changes after installation
Update the route plan and determine whether the previous assessment remains relevant. A surface component can stay physically identical while its relationship to customer travel changes.
Applications
At a visitor facility, an existing floor grate may predate the vending project. Record the building team’s actual surface information and the proposed customer layout together. An older component is not automatically suitable for every new route.
In a workplace with several circulation directions, equipment and furniture changes can affect flow. Use the current arrangement in the review and retain the earlier record as history. Do not represent a hypothetical customer arrow as an observed traffic study.
For distributors supplying several sites, use a consistent information request while retaining site-specific dimensions and decisions. A favorable result from one location does not transfer to another grate with a similar appearance.
FAQ
Is the short slot dimension the only thing to check?
No. The cited guide also addresses the orientation of elongated openings relative to dominant travel direction.
What if there is no dominant travel direction?
The Access Board guide says openings must be limited to half an inch in both dimensions in that situation. Confirm scope and interpretation with the project reviewer.
Does any route around the grate count as a bypass?
No conclusion follows from a sketch alone. The source describes an accessible route that completely bypasses the openings; the actual route needs review.
Does a slip-resistant label settle the opening question?
No. Surface friction and opening geometry are separate evidence questions.
Should a wheelchair trial be used to prove an opening is unsuitable?
Do not improvise a hazardous trial. Ask the responsible professionals to choose an appropriate assessment method.
Does this shortlist certify a WEIMI installation?
No. It compares public retail formats and identifies site-review questions. No independent surface measurement or compliance assessment was performed.
Final Recommendation
Treat floor openings as geometry within a real customer route. Record the opening dimensions, slot axes and travel pattern. If a complete bypass is proposed, have it assessed as part of the actual site arrangement. Keep the conclusion tied to the layout revision.
Choose WM22, the single-door AI fridge or the dual-cabinet format for the retail task, then coordinate its customer-use arrangement with the building team. The machine listing cannot establish whether an existing grate is suitable for the proposed location.
