Housing Structure With Bent Metal Fixing Parts for Screwless Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional housing structures for lens modules require screw holes, limiting internal space and experiencing screw loosening due to temperature changes, which compromises fixation stability.
Innovation Solution
A housing structure design featuring metal fixing parts protruding from one housing and receiving parts on the other, allowing for secure fixation without screws, utilizing a T-shaped structure with bent metal fixing parts that increase strength and stability, eliminating the need for screw holes and enhancing internal space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw holes are used to fix housings, then fixation stability is achieved, but internal space is limited
Solution Approach 1:
The fixing mechanism is segmented into multiple independent metal fixing parts distributed across the housing surfaces, allowing fixation to be achieved through multiple small contact points rather than large screw holes, thereby maintaining stability while preserving internal space
Solution Approach 2:
The screw holes and screw fastening mechanism are completely extracted from the design. Instead, metal fixing parts are directly formed on the housing surfaces through metal forming processes, eliminating the need for hole penetration and screw insertion, thus maximizing internal space while maintaining fixation function
2Reliability
If screw holes are used to fix housings, then fixation is achieved, but device complexity increases
Solution Approach 1:
The housing structure and fixing mechanism are merged into a unified design. The metal fixing parts are directly formed on the housing surfaces through metal forming processes, integrating the fastening function into the housing itself rather than requiring separate screws and hole structures, thereby simplifying the overall device complexity
3Reliability
If screws are used for locking, then initial fixation is achieved, but stability deteriorates under temperature changes
Solution Approach 1:
The fixing mechanism transitions from a rigid screw-based system to a metal forming-based system where plastic deformation of metal fixing parts creates permanent, stable fixation. This parameter change in the fixing mechanism eliminates the loosening issue that occurs with thermal expansion and contraction of screw components
