Electronic Key Waterproof Rubber Assembly Gap Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electronic key designs face issues with breakage of the waterproof rubber during assembly due to excessive external forces causing separation of parts, leading to compression beyond the limit and subsequent damage.
Innovation Solution
The electronic key incorporates a design with gaps between the upper casing projections and waterproof rubber recess portions, allowing for escape and preventing excessive compression, thus maintaining the integrity of the waterproof rubber during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the waterproof rubber is pressed by the projection of the inner casing at the position of the projection of the upper casing during assembly, then the inner casing is assembled to the waterproof rubber, but the waterproof rubber is nipped between the projections and compressed beyond its compression limit causing breakage
Solution Approach 1:
The patent divides the interaction between the inner casing projection and upper casing projection by introducing the waterproof rubber as a separate segment. The waterproof rubber acts as an intermediary element that segments the direct contact between the two projections, allowing assembly while preventing excessive compression that would cause breakage.
Solution Approach 2:
The waterproof rubber serves as an intermediary element between the inner casing projection and the upper casing projection. During assembly, it mediates the interaction by being pressed between the projections but preventing them from directly contacting and over-compressing each other, thus avoiding breakage while enabling proper assembly.
2Ease of manufacture
If the waterproof rubber is pressed by the projection of the upper casing at the position of the projection of the inner casing during assembly, then the inner casing is assembled to the upper casing, but the waterproof rubber is nipped between the projections and compressed beyond the compression limit causing breakage
Solution Approach 1:
The patent segments the assembly process by using the waterproof rubber as an intermediate layer between the upper casing projection and the inner casing projection. This segmentation allows the projections to engage for proper assembly positioning while the waterproof rubber prevents direct over-compression that would lead to breakage.
Solution Approach 2:
The waterproof rubber acts as a mediator during the assembly of the inner casing to the upper casing. It is positioned between the projections to transmit the necessary compression for sealing while preventing excessive force transmission that would cause the rubber to break, thus enabling safe assembly.
3Force
If an increase in external force is applied to the upper casing, then the parts are held firmly, but separation of the inner casing and waterproof rubber from the upper casing occurs
Solution Approach 1:
The patent employs the waterproof rubber as a flexible element that can deform under external force. When force is applied to the upper casing, the flexible waterproof rubber deforms to accommodate the stress while maintaining the sealed connection between the inner casing and upper casing, preventing separation even under increased load.
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
This design effectively prevents breakage of the waterproof rubber during assembly by allowing it to escape and reducing compression beyond the limit, ensuring the rubber remains intact and functional.
Implementation Method 1
the waterproof rubber at the position of the projection of the upper casing is nipped between the projection of the upper casing and the projection of the inner casing, and is compressed more than a compression limit
