Sealed Elastic Button Assembly for Waterproof Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing button assemblies lack effective waterproofing, which can lead to functional failures due to water ingress.
Innovation Solution
A button assembly design featuring a housing with a tubular side wall, a connecting portion made of elastic material, and a pressing portion that covers the opening of the housing, ensuring a sealed connection and preventing water entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional button assembly structures are used, then the structure is simple, but waterproofing function is insufficient
Solution Approach 1:
The pressing portion and connecting portion are integrated into a single piece structure, eliminating the need for separate sealing components. This integration achieves waterproofing by making the pressing portion itself form a sealed connection with the housing through the elastic connecting portion, rather than adding separate gaskets or sealing elements.
Solution Approach 2:
The connecting portion is made of elastic material that can deform to create a sealed connection between the pressing portion and housing. This flexible structure adapts to the housing opening while maintaining water tightness, providing effective sealing without rigid complex sealing mechanisms.
2Reliability
If multiple separate components are used for waterproofing, then waterproofing function is improved, but installation steps increase
Solution Approach 1:
The pressing portion and connecting portion are combined into one integrated component that performs both the pressing function and the sealing function simultaneously. This reduces the number of parts to be assembled and simplifies the installation process while maintaining effective waterproofing.
3Reliability
If traditional sealing methods are used, then waterproofing is achieved, but the number of parts increases
Solution Approach 1:
The sealing function is integrated into the pressing portion itself through the elastic connecting portion, eliminating the need for separate gaskets, O-rings, or sealing plates. This single-component solution provides effective waterproofing while reducing the total part count.
Solution Approach 2:
The pressing portion serves multiple functions: it provides the pressing action for button operation and simultaneously creates the sealed connection for waterproofing through its elastic connecting portion. This multi-functionality eliminates the need for dedicated sealing components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design achieves a good waterproof function by preventing water from entering the button assembly through the pressing portion, while also simplifying the installation process with fewer parts and reduced installation steps.
Implementation Method 1
the connecting portion is made of an elastic material, such that the pressing portion is movable relative to the housing
