Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera modules are complex and costly to manufacture due to their structure, which involves multiple components and assembly processes, and there is a need for a module that can be directly mounted on a main substrate with simplified manufacturing and reduced costs.
Innovation Solution
The camera module features a lens barrel with differently shaped lens units, allowing for varying outer peripheral shapes based on performance, enabling efficient space utilization and manufacturing by forming polygonal or circular shapes depending on the lens unit's requirements, thereby optimizing space and production efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple circuit components are mounted on FPCB and assembled with housing and barrel, then the camera module achieves functional completeness, but the manufacturing process becomes complex and costly
Solution Approach 1:
The patent merges the FPCB, housing, and barrel into a single integrated substrate structure. The substrate serves simultaneously as the mechanical housing, the FPCB mounting platform, and the barrel structure, eliminating the need for separate assembly of these components and simplifying the manufacturing process while maintaining functional completeness
Solution Approach 2:
The substrate is designed to perform multiple functions: it serves as the structural housing, the FPCB carrier, and the barrel assembly. This multi-functional design reduces the total component count and simplifies manufacturing by replacing multiple specialized components with a single universal substrate structure
2Volume of moving object
If lens units with different outer peripheral shapes are disposed in the lens barrel, then space utilization is optimized, but the assembly process becomes more complex
Solution Approach 1:
The patent employs lens units with different outer peripheral shapes (circular, square, rectangular, triangular) matched to corresponding asymmetric recesses in the substrate. This asymmetric design optimizes space utilization by fitting each lens unit precisely into its designated location, while the pre-formed recesses in the substrate simplify the assembly process by providing built-in positioning features
3Reliability
If the camera module is manufactured with traditional COB or COF schemes, then image sensor attachment is reliable, but the manufacturing cost increases and direct mounting on main substrate is not achieved
Solution Approach 1:
The patent extracts the FPCB and housing functions from the traditional camera module architecture and integrates them into the substrate. This extraction eliminates the need for separate FPCB and housing components, enabling direct mounting on the main substrate while reducing manufacturing costs and simplifying the overall structure
Solution Approach 2:
The substrate is designed to directly replicate the functions of the FPCB, housing, and barrel without requiring separate components. By copying and integrating these functions into a single substrate, the module achieves direct mounting capability on the main substrate while maintaining the reliability of image sensor attachment
