Auxiliary Circuit Board Spring Support Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In miniaturized electronic equipment, the limited installation space often results in auxiliary circuit boards being insecurely fixed, leading to potential connection failures due to deformation of the case or main circuit board, especially when supported by springs alone, which cannot absorb loads effectively.
Innovation Solution
A spring supporting mechanism is introduced, comprising a metal plate spring with a fixed portion and deformable arm portions that securely attach the auxiliary circuit board to the case, preventing displacement and maintaining connection stability by absorbing external forces through elastic deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the auxiliary circuit board is supported by springs only, then the installation space is reduced, but the board cannot be stably supported under load
Solution Approach 1:
The patent combines two support methods: spring support for one end and screw fixation for the other end. This merging of flexible spring support and rigid screw fixation allows the auxiliary circuit board to be stably supported under load while maintaining compact installation space.
Solution Approach 2:
The support structure is segmented into two distinct parts: a spring support portion for one end of the board and a screw fixation portion for the other end. This segmentation allows each part to perform its specialized function optimally - springs providing flexible support and screws providing rigid anchoring.
2Reliability
If the case is deformed by load, then the auxiliary circuit board is displaced relative to the main circuit board, but using rigid fixation increases structural complexity
Solution Approach 1:
The spring support acts as a pre-configured cushioning element that anticipates and absorbs deformation forces before they can cause displacement or connection failure. The spring's elastic properties allow it to compensate for case deformation, maintaining connection stability without requiring complex rigid fixation structures.
3Volume of moving object
If one end is connected to the connector at the edge of the main circuit board, then the installation space is optimized, but the board becomes vulnerable to displacement
Solution Approach 1:
Different portions of the auxiliary circuit board are provided with different support qualities: one end receives flexible spring support while the other end receives rigid screw fixation. This local differentiation in support quality allows the board to be securely positioned with optimized installation space while compensating for the vulnerability of edge-mounted connectors.
