Camera Module Ceramic Board Concave Housing for Miniaturization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera modules face challenges in miniaturization and increased durability due to the need for additional space for image sensors and infrared (IR) cut-off filters, which also complicates maintenance and repair.
Innovation Solution
The camera module design incorporates a ceramic board with concave portions for housing image sensors and IR cut-off filters, reducing overall height and eliminating the need for additional holders, while allowing for easy integration and replacement of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional holders and separate mounting structures are used for image sensors and IR cut-off filters, then reliability and stability are improved, but device complexity and overall size increase
Solution Approach 1:
The patent integrates the image sensor and IR cut-off filter directly onto the ceramic board, eliminating the need for separate holders and mounting structures. This merging of components reduces structural complexity while maintaining component stability through direct integration onto a rigid substrate.
Solution Approach 2:
The ceramic board serves multiple functions simultaneously: it acts as the mounting substrate for the image sensor, holds the IR cut-off filter in position, provides electrical connections, and offers mechanical support. This multi-functionality eliminates the need for separate specialized holders for each component.
2Manufacturing precision
If more space is allocated for image sensors and IR cut-off filters, then manufacturing precision is improved, but the camera module size increases
Solution Approach 1:
The patent utilizes the vertical dimension by creating a concave portion that extends downward from the surface of the ceramic board. This allows the image sensor and IR cut-off filter to be positioned in the vertical space rather than requiring additional horizontal area, thereby maintaining compact overall dimensions while providing sufficient positioning precision.
Solution Approach 2:
The image sensor and IR cut-off filter are nested within the concave portion of the ceramic board structure. This nesting arrangement allows multiple components to occupy the same vertical space, reducing the overall camera module height while maintaining proper spacing and positioning accuracy for each component.
3Ease of repair
If separate holders are used for mounting components, then ease of repair is improved, but device complexity increases
Solution Approach 1:
The ceramic board is designed with a removable cover structure that segments the housing into accessible and protected portions. This allows the image sensor and IR cut-off filter to be accessed and replaced by simply removing the cover, maintaining ease of repair without requiring disassembly of multiple separate holder structures.
