Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the maximum viewing angle is increased to 130° or more for super-wide-angle lenses, then the field of view is improved, but aberration control becomes difficult and image quality degradation in the periphery increases
Solution Approach 1:
The lens assembly is divided into multiple lens groups (first lens group with positive refractive power, second lens group with negative refractive power, and third lens group with positive refractive power) rather than using a single lens element. This segmentation allows each group to contribute differently to aberration correction while maintaining the super-wide-angle viewing angle of 130° or more
Solution Approach 2:
Each lens group is designed with specific refractive power characteristics (positive, negative, and positive respectively) to address different aberration issues in different regions of the optical path. The first lens group handles initial light convergence, the second lens group corrects for wide-angle distortion, and the third lens group fine-tunes the focal properties, creating localized quality optimization throughout the system
2Volume of moving object
If the camera lens is designed to be compact for miniaturization in electronic devices, then the space efficiency is improved, but aberration control and optical performance become difficult to optimize
Solution Approach 1:
The patent introduces a bending unit that folds the optical path, effectively adding a spatial dimension to the optical design. This allows the optical path length to be extended within a compact physical footprint, enabling aberration control and multiple lens groups to be arranged in a folded configuration rather than a straight line, thus achieving both compactness and optical performance
Solution Approach 2:
The bending unit is integrated within the compact lens assembly structure, with the optical path folding back on itself within the limited space. This nesting approach allows the optical components to be arranged efficiently in three-dimensional space, fitting a longer effective optical path into a smaller overall volume
3Adaptability or versatility
If multiple lens optical systems are included in the electronic device, then the imaging functionality is improved, but the device complexity and space requirements increase
Solution Approach 1:
The lens assembly is designed with a modular multi-group structure that can serve multiple imaging functions. The same basic architecture (three lens groups with specific refractive powers and a bending unit) can be replicated or adapted for different imaging requirements, allowing the system to handle various imaging tasks with a standardized design approach rather than requiring completely separate optical systems
