Wireless Switch Push Button Lockout Against Accidental Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless switches with push buttons can be inadvertently operated when dropped or transported, leading to incorrect functioning.
Innovation Solution
A wireless switch design featuring a movable push button, a signal output device, and a restriction member that prevents the push button from moving from a non-operating to an operating position, ensuring the button remains in its non-operating position unless intentionally activated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a push button is made movable between non-operating and operating positions, then the wireless switch can be operated to control loads, but the push button may be wrongly operated when the device is dropped or transported
Solution Approach 1:
The restriction member is designed to be movable between a restriction position (where it blocks the push button) and a release position (where it allows the push button to move). This dynamic mechanism allows the system to adapt between preventing wrong operation during transport and enabling intentional operation when needed, resolving the contradiction between ease of operation and reliability
2Reliability
If a restriction member is added to prevent wrong operation, then the push button is protected during transport, but the device complexity increases
Solution Approach 1:
The restriction member is integrated with the push button assembly, where the restriction member, push button, and signal output device work together as a unified mechanism. The restriction member utilizes the same movement space and structural framework as the push button, merging multiple functions into a compact design that prevents wrong operation without significantly increasing overall device complexity

AI summary
A wireless switch includes a switch body, a push button connected to the switch body in a state of being movable along an approaching/separating direction between a non-operating position and an operating position, a signal output device accommodated in the switch body and configured to output a switch signal in response to a movement of the push button from the non-operating position to the operating position, and a restriction member that restricts the movement of the push button from the non-operating position to the operation position when the push button is located at the non-operating position.
