Camera Module Stopper Structure for Impact-Resistant Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Camera modules experience weak fastening force between the stopper and resin injection components due to strong impacts, leading to separation and loss of function.
Innovation Solution
The camera module integrates a stopper and support member made of the same metal material, with protrusions and through-holes for enhanced coupling, ensuring increased adhesion between the frame and stopper.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the stopper is made of a thin piece of metal and the frame is made of resin injection product, then the device complexity is reduced and manufacturing is easier, but the fastening force between the stopper and frame is weak under strong impact
Solution Approach 1:
The patent merges the stopper and support member into a single integrated component made of the same metal material. This combination eliminates the interface between the stopper and resin frame, directly addressing the weak fastening force issue while maintaining manufacturing efficiency through unified production processes.
Solution Approach 2:
The patent applies homogeneity by making the stopper and support member from the same metal material with identical properties. This ensures uniform strength and fastening characteristics throughout the assembly, eliminating the weakness caused by material heterogeneity between the stopper and resin frame.
2Device complexity
If the stopper is made of a thin piece of metal, then the device complexity is reduced, but the fastening force between the stopper and resin injection components is weak when strong impact is transmitted
Solution Approach 1:
The patent combines the stopper and support member into a single integrated metal component, eliminating the reliability issues associated with the thin metal stopper separately attached to the resin frame. This merging maintains structural simplicity while significantly improving fastening reliability under impact.
Solution Approach 2:
The patent employs composite material strategy by integrating the stopper and support member as a unified metal structure within the resin frame assembly. This composite approach leverages the strength of metal while maintaining the overall device structure, improving reliability without substantially increasing complexity.
