Sealed Modular Button Assembly for Repairable Device Inputs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electronic device input mechanisms are difficult to seal, allowing contaminants to enter and are not easily testable or repairable, complicating manufacturing and maintenance.
Innovation Solution
A modular button assembly with a sealed button housing and a sensor for detecting inputs, which is separate from the device enclosure and can be easily installed, tested, and replaced, featuring a seal between the button housing and the enclosure to prevent moisture and contaminants from entering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional input mechanisms are integrated into the device enclosure, then structural integration is achieved, but sealing becomes difficult and contaminants can enter the device
Solution Approach 1:
The button assembly is divided into separate modular components: a button housing containing the input mechanism, a seal element, and an electrical connector. This segmentation allows the button assembly to be attached to the enclosure as a discrete unit with pre-integrated sealing, eliminating the need to integrate buttons directly into the enclosure structure while maintaining effective sealing against contaminants.
2Strength
If traditional input mechanisms are structurally integrated, then structural strength is improved, but component-level testing and repair become difficult
Solution Approach 1:
The button assembly is designed as a modular unit that can be attached and detached from the enclosure without compromising structural integrity. The housing provides structural strength while the modular design enables easy removal for testing and repair of internal components such as the sensor and electrical connector.
Solution Approach 2:
The button assembly is extracted as a separate testable unit from the main device structure. This allows the button assembly to be tested independently at the component level before final assembly, and enables repair or replacement of the button assembly without disassembling the entire device.
3Object-affected harmful factors
If a seal is added to prevent contaminant entry, then sealing effectiveness is improved, but device complexity increases
Solution Approach 1:
The seal is merged with the button housing to form an integrated sealing structure. The housing itself is designed to incorporate the seal element, eliminating the need for separate sealing components and reducing overall assembly complexity while maintaining effective contaminant prevention.
Solution Approach 2:
The seal acts as an intermediary element between the button housing and the enclosure, creating a barrier against contaminants. This intermediary sealing mechanism provides effective protection without requiring complex integration of multiple sealing systems into the device structure.

AI summary
A modular button assembly includes a button housing that may be disposed in an opening of an enclosure of an electronic device. The modular button assembly may include an input member that forms an exterior surface of the button housing and is configured to receive inputs, for example from a user of the electronic device. The modular button assembly may further include a sensor for detecting the received inputs and transmitting a signal to a processor of the electronic device. The modular button assembly may be configured such that disposing the button housing in the opening of the enclosure forms a seal that prevents contaminants from entering the button housing and the enclosure.
