Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple lenses are used to meet higher photographic requirements, then the imaging capability is improved, but the alignment accuracy between optical axis and CMOS sensor deteriorates
Solution Approach 1:
The patent integrates multiple lens assemblies into a single multi-lens frame structure, where the frame is manufactured as one integral component. This merging of multiple lens holders into a unified structure ensures that all lens optical axes are pre-aligned relative to each other and to the CMOS sensor, eliminating alignment errors that would occur if lenses were separately mounted. The integral frame design maintains precise optical alignment while accommodating multiple lenses for enhanced imaging capability.
2Reliability
If signal transmission elements are embedded in the multi-lens frame, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The patent combines signal transmission elements directly into the multi-lens frame structure during the integral manufacturing process. The frame is designed with embedded conductive traces or wiring channels that provide electrical connections between lenses and the CMOS sensor. This integration eliminates the need for separate wiring harnesses or connection components, reducing overall device complexity while improving reliability by preventing connection failures during assembly and operation.
3Volume of moving object
If the optical module size is minimized, then the compactness is improved, but the light transmission efficiency deteriorates
Solution Approach 1:
The patent employs a multi-lens arrangement within a compact frame structure that optimizes the spatial distribution of optical elements. By carefully designing the three-dimensional layout of lenses, light channels, and accommodating holes, the module achieves minimal size while ensuring adequate light transmission paths. The integral frame design allows precise positioning of each lens element to maximize light gathering efficiency without increasing overall module volume.
