Dual Camera Module Vertical Sensor Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dual camera modules have design and structural issues, such as exposure of internal components and increased length, which affect their functionality and aesthetics, particularly for wide-angle camera modules.
Innovation Solution
A dual camera module design featuring a first camera module with a narrower angle and a second camera module with a wider angle, where the second image sensor is positioned higher than the first, and both modules have optimized housing and substrate configurations to minimize exposure and length, including the use of non-conductive adhesives and flexible substrates for alignment and attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a broad window is used to obtain a wide angle of view for the wide angle camera module, then the angle of view is improved, but the inner structure of the camera module is exposed, causing design damage
Solution Approach 1:
The patent positions the wide angle camera module in a different spatial dimension (higher position) relative to the narrow angle camera module. This vertical arrangement allows the wide angle module to achieve a broader viewing angle while the housing structure effectively shields the internal components from exposure, resolving the contradiction between angle of view and design appearance.
2Adaptability or versatility
If a large PCB is used to provide electrical conductive structures for connecting optical elements, then the electrical connectivity is improved, but the total length of the dual camera module increases
Solution Approach 1:
The patent integrates the electrical connection structures directly into the housing that accommodates the camera modules. By merging the housing structure with the electrical conductive pathways, the design eliminates the need for a separate large PCB, thereby maintaining comprehensive electrical connectivity while significantly reducing the overall length of the dual camera module.
3Shape
If the second image sensor is positioned higher than the first image sensor, then the internal structure exposure is minimized, but the alignment precision requirement increases
Solution Approach 1:
The patent introduces a non-conductive adhesive as an intermediary element between the first and second image sensors. This adhesive layer not only bonds the sensors to the housing but also serves as a positioning medium that facilitates precise alignment. The adhesive compensates for dimensional variations and enables accurate positioning of the higher-placed second image sensor, thereby reducing the overall alignment precision requirements.
