Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If optical elements are arranged closely to reduce device size, then device compactness is improved, but manufacturing precision and assembly difficulty deteriorate
Solution Approach 1:
The optical element assembly is divided into multiple independent components (first optical element assembly and second optical element assembly) that can be manufactured and assembled separately. Each assembly has its own receiving space within the lens barrel, allowing for modular manufacturing that reduces overall device size while maintaining assembly precision through standardized interfaces and positioning structures.
2Reliability
If complex optical designs are implemented to improve image quality, then imaging performance is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The lens barrel structure serves multiple functions simultaneously: it provides receiving spaces for optical element assemblies, includes positioning structures (protrusion portions and retainer structures) for precise assembly, and incorporates light blocking structures to prevent stray light. This multi-functional design achieves complex imaging requirements without proportionally increasing structural complexity.
3Reliability
If light blocking structures are added to reduce stray light, then image quality is improved, but device complexity increases
Solution Approach 1:
The light blocking structure is merged with the lens barrel structure itself rather than being a separate component. The light blocking structure is integrated into the receiving spaces and positioning structures of the lens barrel, achieving stray light reduction while minimizing additional structural complexity through functional integration.

AI summary
An imaging lens module includes a plastic lens barrel, a first optical element assembly and a second optical element assembly, wherein both of the first optical element assembly and the second optical element assembly are disposed in the plastic lens barrel. The plastic lens barrel includes a first inner annular surface and a second inner annular surface. The first inner annular surface forms a first receiving space. The second inner annular surface forms a second receiving space. The first optical element assembly is disposed in the first receiving space and includes a plurality of optical lens elements and a first retainer. The second optical element assembly is disposed in the second receiving space and includes a first light blocking sheet and a second retainer.
