Industrial Button Cover Structure for Impact-Resistant Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing button guards or shields fail to provide sufficient mechanical protection to prevent damage to buttons in industrial environments, leading to undesirable downtime and increased operating costs due to accidental impacts from objects like pushcarts and pallet jacks.
Innovation Solution
A button cover with a sleeve and dividing wall that redistributes external forces away from the button to the button panel and housing, featuring a design with recesses, attachment holes, and optional support ridges or ribs to absorb and redirect impact, fabricated from rigid materials like plastic or composite materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing button guards or shields are used to prevent accidental button actuation, then button activation safety is improved, but mechanical protection against damage from external impacts is insufficient
Solution Approach 1:
The button cover is divided into multiple functional segments: a protective outer shell, an inner button mounting structure, and attachment mechanisms. This segmentation allows the outer shell to absorb impact forces while the inner structure protects the button, resolving the contradiction between safety and mechanical strength.
Solution Approach 2:
The button cover design incorporates energy-absorbing features and force-distributing structures that prepare the system to withstand external impacts before they occur. The cover acts as a sacrificial protective layer that absorbs impact energy, preventing direct transmission to the button and thereby providing both safety and mechanical strength.
2Reliability
If button covers are designed to be held down by the button, then accidental actuation is prevented, but the button becomes vulnerable to damage when the guard is damaged
Solution Approach 1:
The button cover is segmented into a protective outer shell and an inner mounting structure, allowing the shell to bear impact loads while the button remains protected within. This separation prevents the button from bearing both the safety function and mechanical stress simultaneously.
Solution Approach 2:
The button cover acts as an intermediary protective element between external impact forces and the button. It absorbs and redistributes forces away from the button, preventing direct transmission of impact loads while maintaining the safety function of preventing accidental actuation.
3Strength
If kick plates are bolted around the button station housing to protect buttons, then mechanical protection is improved, but safety is compromised due to tripping hazards
Solution Approach 1:
The protective function is extracted from the housing structure itself and implemented through a separate, removable button cover. This allows the housing to remain clean and free of protruding elements that could create tripping hazards, while the cover provides the necessary mechanical protection.
Solution Approach 2:
A separate button cover serves as an intermediary protective element that can be attached or removed as needed. This provides mechanical protection without permanently modifying the housing structure or creating tripping hazards, allowing the housing to maintain its safety-friendly design.

AI summary
A safety button cover for use with a button station is provided. The safety button cover comprises a button cover sleeve with a first and second open end that define an interior space therebetween. A dividing wall is provided between the first and second open ends to separate the interior space into a first recess and second recess. The dividing wall further includes at least one opening to permit a corresponding button of the button station to extend from the first recess through the opening into the second recess. When the safety button cover is installed over the button station, a portion of the button cover sleeve surrounds a button panel and a portion of a button housing on which the button is installed to define an overlap region between the safety button cover and the button station.
