Solution Overview
Problem
Conventional cooling structures for electrical components face issues with liquid leakage and vibration isolation due to separate components for sealing and anti-vibration, requiring complex assembly and potential dimensional variations.
Innovation Solution
An integrated liquid leakage prevention and anti-vibration component comprising a support plate with double sealing gaskets and anti-vibration rubbers, fixed to the electrical component body and housing, which are bonded as a single unit to prevent leakage and isolate vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate seal member and anti-vibration member are used, then waterproofing and anti-vibration functions are achieved, but assembly complexity increases and dimensional variations occur
Solution Approach 1:
The patent combines the seal member and anti-vibration member into a single integrated component. The seal member includes both the sealing function and the anti-vibration function in one piece, eliminating the need for separate components. This reduces assembly complexity while maintaining both waterproofing and anti-vibration reliability.
Solution Approach 2:
The seal member is designed to perform multiple functions simultaneously: it provides sealing to prevent water ingress, acts as an anti-vibration element to dampen vibrations, and serves as a mounting structure. This multi-functional design eliminates the need for separate dedicated components for each function.
2Reliability
If separate seal member and anti-vibration member are used, then waterproofing and anti-vibration functions are achieved, but manufacturing time increases
Solution Approach 1:
By merging the seal member and anti-vibration member into one integrated component, the number of assembly steps is reduced. Instead of assembling two separate parts, the single integrated component is installed as one unit, significantly reducing manufacturing time and improving productivity.
Solution Approach 2:
The anti-vibration rubber is pre-integrated into the seal member structure during manufacturing. This preliminary integration means that during assembly, no additional steps are required to install the anti-vibration element separately - it is already in place as part of the seal member, reducing assembly time.
3Temperature
If cooling liquid channel is formed in housing, then cooling function is achieved, but housing structure complexity increases
Solution Approach 1:
The cooling system is segmented into separate functional elements: the housing provides structural support and mounting, while the cooling liquid channel is formed as a separate component that can be attached to the housing. This segmentation allows the housing to remain structurally simple while still achieving effective cooling through the integrated channel component.
