Self-Service Store Access Device Concealing Mounting Foot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access devices for transit systems in self-service shops have a protruding mounting base that complicates cleaning, as it creates areas where dirt can accumulate and is difficult to remove, and requires operators to navigate around both the support element and the mounting base during cleaning, increasing the risk of collision.
Innovation Solution
The access device features a separate mounting base and support element design, where the support element completely covers the mounting base from a viewing perspective, allowing for easy installation and cleaning without collisions, with a connecting element that provides secure attachment and a robust structure, and includes a stabilization plate and security features for reliable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mounting base has a lateral overhang to allow screw mounting, then the support element can be securely attached to the floor, but the overhang creates areas where dirt accumulates and is difficult to clean
Solution Approach 1:
The support element is designed to completely cover the mounting base from above, with the mounting base nested within the support element's footprint. The lateral overhang of the mounting base is positioned within the boundary of the support element, creating a nested configuration where the visible support element conceals the mounting base structure that causes cleaning difficulties.
Solution Approach 2:
The mounting base is extracted as a separate component from the support element, allowing the support element to be designed with a clean, simple top surface that completely covers the mounting base. This separation enables the mounting base to provide secure attachment functionality while remaining hidden beneath the support element, eliminating the cleaning problem associated with visible overhangs.
2Ease of manufacture
If the mounting base has a lateral overhang, then screw mounting is enabled, but operators must navigate around both the support element and mounting base during cleaning, increasing collision risk
Solution Approach 1:
The mounting base is nested within the support element's horizontal footprint, with the lateral overhang positioned inside the support element's boundary. This nested arrangement presents a single, clean operational surface to cleaning operators, eliminating the need to navigate around multiple protruding components and reducing collision risk.
3Ease of manufacture
If the mounting base and support element are designed as separate components, then assembly is simplified and the support element can completely cover the mounting base, but additional connecting elements are required
Solution Approach 1:
The access device is segmented into two distinct components: the mounting base for floor attachment and the support element for the blocking element. This segmentation allows each component to be optimized independently and simplifies assembly, as the support element can be separately manufactured and then attached to the mounting base using standard connecting elements like screws or snap-fits.
Solution Approach 2:
The separate component design enables the support element to be configured with a larger horizontal footprint than the mounting base, allowing it to completely cover the mounting base when assembled. The nested configuration of the mounting base within the support element's footprint is achieved through the separate component design, providing both assembly simplicity and the desired visual appearance.
