Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional optical lenses are used to achieve high resolution, then imaging quality is improved, but system thickness and cost increase
Solution Approach 1:
The optical system is divided into multiple functional modules: a bionic lens for light collection, a beam splitting prism for light path separation, and a reflective optical element for focusing. This segmentation allows each component to be optimized independently, achieving high resolution while maintaining thinness by distributing optical functions across separate elements rather than requiring a single thick lens
Solution Approach 2:
The patent introduces a reflective optical element that reflects light rays at approximately 90 degrees to redirect them onto the imaging surface. This dimensional change in light path direction enables the system to achieve high resolution imaging within a reduced thickness by utilizing spatial redirection rather than direct linear propagation
2Measurement precision
If conventional optical lenses are used to achieve high resolution, then imaging quality is improved, but manufacturing cost increases
Solution Approach 1:
The patent replaces conventional high-resolution lens systems with a combination of a bionic lens and a reflective optical element. This substitution uses simpler, more manufacturable components - the bionic lens for light gathering and the reflective element for focusing - thereby reducing manufacturing complexity and cost while maintaining high imaging resolution
3Length of stationary object
If reflective optical elements are introduced to reduce thickness, then system compactness is improved, but device complexity increases
Solution Approach 1:
The patent merges the beam splitting function and the light reflecting function into a single integrated optical system. The beam splitting prism and reflective optical element work together as a unified assembly, reducing the number of separate components and simplifying the overall device structure despite the introduction of reflective elements for thinness
