Hook-Fastened Camera Module Structure for Multi-Substrate Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing camera module structures with multiple substrates face issues of reduced component mounting space due to screw-based coupling, increased manufacturing time, and potential substrate bending during assembly.
Innovation Solution
A camera module design utilizing a hook fastening structure with support members that include hooks and protrusions to secure substrates in an optical axis direction, minimizing space usage and preventing substrate separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to fix multiple substrates, then the substrates can be securely fastened, but the component mounting space is reduced and manufacturing time increases
Solution Approach 1:
The patent extracts the fastening function from traditional screws and replaces it with a hook structure that is integrated into the support member. The hook protrudes from the support member and engages with the substrate edge, eliminating the need for separate screw fasteners and reducing manufacturing complexity while maintaining secure attachment.
Solution Approach 2:
The support member is designed to combine multiple functions: structural support, positioning, and fastening. The hook structure is integrated directly into the support member body, merging the fastening function with the support function into a single component, thereby reducing the number of parts and simplifying assembly.
2Reliability
If screws are used to fix multiple substrates, then the substrates can be securely fastened, but the component mounting space is reduced
Solution Approach 1:
The patent removes the screw fasteners from the system and replaces them with a hook structure that requires no additional fastening components. This extraction of the fastening function from separate screws eliminates the space that would otherwise be occupied by screw heads, screwholes, and associated hardware, thereby increasing available mounting space.
3Reliability
If excessive torque is applied when fastening screws, then the substrates can be securely fastened, but substrate bending occurs
Solution Approach 1:
The patent extracts the high-torque screw fastening operation from the assembly process and replaces it with a hook structure that applies gentle, distributed force. The hook engages with the substrate edge and provides secure attachment without requiring excessive torque, thereby preventing substrate bending while maintaining fastening reliability.
4Adaptability or versatility
If a multiple substrate stack structure is used, then the camera module functionality is enhanced, but the manufacturing complexity increases
Solution Approach 1:
The patent merges the fastening function into the support member structure itself, creating an integrated solution that simplifies the manufacturing process. The hook structure is formed as part of the support member, eliminating the need for separate fastening operations and reducing assembly steps while maintaining the ability to securely attach multiple substrates.
