Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bumpers for product storage fixtures face issues such as susceptibility to abrasions, deformation, and difficult installation, with visible fasteners being unsightly and potentially hazardous, and existing solutions either break or become deformed when hit by objects, or require complex installation processes.
Innovation Solution
A two-piece bumper assembly comprising an elongate rigid stainless steel shell and a flexible base with latching elements, which provides abrasion and deformation resistance, and a simplified installation process, with end caps for aesthetic and functional integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional flexible plastic bumpers are used, then impact absorption is improved, but abrasion resistance and deformation resistance deteriorate
Solution Approach 1:
The bumper assembly combines a rigid shell (metal or hard plastic) with a flexible bumper element (soft material), creating a composite structure that provides both impact absorption and abrasion/deformation resistance. The rigid shell protects against wear while the flexible element absorbs impact forces.
2Reliability
If conventional metallic bumpers are used, then abrasion and deformation resistance are improved, but impact absorption capability deteriorates
Solution Approach 1:
The bumper assembly combines a rigid shell (metal or hard plastic) with a flexible bumper element (soft material), creating a composite structure that provides both impact absorption and abrasion/deformation resistance. The rigid shell protects against wear while the flexible element absorbs impact forces.
3Ease of operation
If visible fasteners are used to attach bumpers, then installation simplicity is improved, but aesthetic appearance deteriorates
Solution Approach 1:
The fasteners are extracted from the visible exterior and relocated to the interior of the bumper assembly. The shell covers the fasteners, hiding them from view while maintaining secure attachment. This separates the functional requirement (secure attachment) from the aesthetic requirement (clean appearance).
4Reliability
If complex installation processes are used, then attachment reliability is improved, but installation time and complexity deteriorate
Solution Approach 1:
The bumper assembly is segmented into modular components (shell, bumper element, fasteners) that can be independently manufactured and assembled. This allows for simplified installation while maintaining reliable attachment through standardized connection mechanisms.
5Ease of operation
If bumper material is made thinner, then ease of installation and flexibility are improved, but strength and deformation resistance deteriorate
Solution Approach 1:
The bumper assembly combines a rigid shell (metal or hard plastic) with a flexible bumper element (soft material), creating a composite structure that provides both impact absorption and abrasion/deformation resistance. The rigid shell protects against wear while the flexible element absorbs impact forces.

AI summary
A bumper assembly includes an elongate rigid shell formed of a metallic material and an elongate base. The elongate rigid shell includes an inner surface, an outer surface, a first shell edge, and a first flange protruding from the first shell edge in a direction toward the inner surface of the elongate rigid shell. The elongate base includes a base body including a first base edge and a first flexible latching element extending from the first base edge of the base body, the first flexible latching element including a first latching protrusion having a first inclined outer surface and a first shoulder. The elongate base is configured for insertion into the elongate rigid shell with the first flange compressing the first flexible latching element and engaging the first shoulder of the first latching protrusion.
