Solution Overview
Problem
Existing periscopic camera modules are large in size and complex in structure, occupying valuable space within portable electronic devices and complicating assembly, which hinders their integration and mass production efficiency.
Innovation Solution
A periscopic camera module design utilizing a first reflective element, an optical lens, and a second reflective element, such as a triangular or parallelogram prism, to fold the optical path laterally, reducing the overall length and incorporating a photosensitive chip closer to the optical lens, with integrated reflecting surfaces and housings to facilitate compactness and ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the optical path is folded laterally using a second reflective element (prism), then the volume of the camera module is reduced, but the structural complexity increases
Solution Approach 1:
The patent applies dimensional transformation by folding the optical path laterally using a second reflective element (prism) instead of extending it linearly. This transforms the optical path from a one-dimensional linear arrangement to a two-dimensional folded configuration, reducing the longitudinal volume occupation while managing structural complexity through systematic design.
Solution Approach 2:
The patent implements nesting by integrating the second reflective element (prism) with the housing structure. The prism is positioned within the housing space, and the housing itself serves as part of the optical path structure, allowing components to be nested within each other to reduce overall volume while maintaining functional integrity.
2Measurement precision
If the periscopic camera module is designed for high-magnification zoom capability, then the imaging quality is improved, but the assembly difficulty increases
Solution Approach 1:
The patent divides the camera module into distinct functional segments: a first reflective element for longitudinal turning, an optical lens for imaging, and a second reflective element for lateral turning. This segmentation allows each component to be optimized for its specific function and assembled in a modular fashion, improving imaging quality while managing assembly complexity through standardized interfaces.
Solution Approach 2:
The housing structure serves multiple functions: it provides mechanical support, defines the optical path, and integrates with the second reflective element. This multi-functionality reduces the number of separate components needed, thereby improving imaging quality through precise optical alignment while simplifying the assembly process.
