Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the light folding component and lens element are preliminarily installed on two individual retainers and then assembled, then the assembly process is flexible, but assembly errors occur and image quality is compromised
Solution Approach 1:
The patent merges the light folding component and lens element into a single integrated optical assembly that is pre-aligned as one unit. This integration ensures precise relative positioning between components while maintaining manufacturing flexibility through modular design, directly resolving the contradiction between assembly flexibility and precision.
2Ease of manufacture
If the light folding component is installed separately, then the assembly process is simple, but the component is easily damaged or displaced by external forces
Solution Approach 1:
The light folding component is merged with the lens element and retainer into an integrated assembly structure. This combination provides mutual support and protection among components, preventing displacement and damage from external forces while maintaining assembly simplicity through the unified structure.
Solution Approach 2:
The integrated design incorporates protective structural features that cushion and absorb external forces before they can damage or displace the light folding component. The unified structure inherently provides mechanical protection, ensuring reliability without complicating the assembly process.
3Ease of manufacture
If conventional assembly methods are used, then the manufacturing process is straightforward, but assembly errors compromise image quality
Solution Approach 1:
The patent combines multiple optical components into a pre-aligned integrated assembly that maintains precise relationships between elements. This merging ensures high alignment precision for image quality while keeping the manufacturing process straightforward through the unified modular design.
Solution Approach 2:
The light folding component and lens element are pre-assembled and pre-aligned into a configured unit before final installation. This preliminary action ensures precise alignment is achieved during manufacturing, preventing assembly errors that would compromise image quality while maintaining process simplicity.

AI summary
An imaging lens module includes an optical element holder being one-piece formed, a lens element and a light folding component corresponding to the lens element. Each of two side surfaces of the optical element holder has a light through hole, and light passes through the optical element holder via the light through holes. The optical element holder includes a lens element accommodation portion and a folding component accommodation portion respectively for the lens element and the light folding component to be disposed therein. The light folding component includes a light receive surface, a first reflection surface and a light exit surface. The light enters the light folding component from the light receive surface, the first reflection surface is configured to reflect the light coming from the light receive surface so as to redirect the light, and the light exits the light folding component from the light exit surface.
