Electronic Part Housing Box Spring Biasing Vibration Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic part housing boxes fail to effectively suppress vibration of capacitors and other electronic parts with lead wires, leading to potential breakage due to unbalanced housing and lack of biasing forces, especially when parts with varying heights are housed.
Innovation Solution
Incorporating a first spring portion on the base member and a second spring portion on the part housing cover to bias the electronic parts within the housing chamber, ensuring balanced forces and minimizing gaps, thus reducing vibration and stress on lead wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the part housing chamber height is set based on the maximum height capacitor, then capacitors with smaller heights have gaps and vibrate easily, but increasing the chamber height to eliminate gaps increases the overall housing size and complexity
Solution Approach 1:
The patent applies the dynamics principle by introducing a spring portion that enables dynamic adjustment of the capacitor position within the housing chamber. The spring portion allows the capacitor to be pressed against the bottom surface, eliminating gaps and preventing vibration, while accommodating capacitors of varying heights without requiring a larger housing chamber. This dynamic mechanism resolves the contradiction by providing both vibration suppression and compact housing volume.
2Reliability
If capacitors with varying heights are housed in a fixed-height chamber, then smaller capacitors have gaps causing vibration, but creating adjustable housing structures increases device complexity
Solution Approach 1:
The patent applies the self-service principle by designing a spring portion that automatically adjusts to accommodate capacitors of different heights without requiring external adjustment mechanisms. The spring portion self-regulates the pressure and position of the capacitor, eliminating gaps and preventing lead wire breakage due to vibration, while maintaining simple housing structure. This resolves the contradiction by providing reliable lead wire protection without increasing device complexity.
