Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single lens module is used, then the device complexity is reduced, but the focusing speed and image clarity deteriorate when switching between macro distances
Solution Approach 1:
The single lens module is segmented into multiple independent lens units, each optimized for specific focusing distances (macro, normal, telephoto). This segmentation allows the system to switch between pre-optimized lenses rather than continuously adjusting a single lens, dramatically improving focusing speed while maintaining manageable device complexity through modular architecture
Solution Approach 2:
The lens module implements dynamic lens switching capability where the system can rapidly change between different lens units based on real-time focusing distance requirements. This dynamic adaptation eliminates the focusing delay inherent in single-lens systems while keeping the overall structure relatively simple through automated control mechanisms
2Ease of manufacture
If a single lens module is used, then the manufacturing cost is reduced, but the image clarity deteriorates when switching focus distances
Solution Approach 1:
The imaging system is divided into multiple specialized lens modules, each manufactured with optimized precision for its specific function. This allows each lens to be manufactured with targeted precision requirements rather than requiring a single lens to handle all focusing distances, improving overall image clarity while potentially reducing total manufacturing complexity through standardized modular production
Solution Approach 2:
Each lens module is designed with local quality optimization, where macro lenses have specific optical characteristics for close-up imaging, normal lenses for standard distances, and telephoto lenses for distant subjects. This localized optimization ensures high image clarity for each specific application while allowing standardized manufacturing processes for each module type
3Adaptability or versatility
If multiple lenses are added, then the capturing versatility is improved, but the device complexity increases
Solution Approach 1:
The multiple lens system is organized into distinct, independently controllable modules that can be selectively activated. This segmentation provides capturing versatility for macro, normal, and telephoto distances while managing device complexity through modular design where each lens unit operates as a self-contained functional block
Solution Approach 2:
The lens module system implements multi-functionality by integrating multiple lens types that can be dynamically switched based on capturing requirements. This universal design allows a single lens module assembly to perform various capturing functions (macro photography, standard photography, telephoto photography) that would otherwise require separate devices, thereby improving versatility without proportionally increasing overall device complexity

AI summary
A multiple lenses system includes a lens module, a processing unit, a switching unit, and a focus module. The lens module includes a plurality of lenses. The switching unit is electrically connected to the plurality of lenses and the processing unit. The focus module includes a laser emitter and a laser receiver. The laser emitter emits laser beam towards an object under control of the processing unit. The laser receiver receives the laser beam reflected by the object. The processing unit obtains a focus distance between the object and the focus module according to a time difference from emitting the laser beam to receiving the laser beam, and controls the switching unit to switch and to select at least one of the plurality of lenses according to the focus distance.
