Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing lens devices are used for capturing images, then the basic imaging function is achieved, but the ability to display multiple different scenes is limited
Solution Approach 1:
The lens device is divided into multiple lens units, each capable of capturing different scenes (e.g., wide-angle, telephoto, macro). Each lens unit has its own optical path and imaging sensor, allowing simultaneous capture of multiple scenes that are then displayed on a single screen.
Solution Approach 2:
The lens device integrates multiple lens units with different optical functions (wide-angle, telephoto, macro) into a single device, making it universally capable of capturing various scene types without requiring separate devices or complex mechanical switching mechanisms.
2Adaptability or versatility
If multiple lens structures are added to display different scenes, then the scene diversity is improved, but the device complexity and cost increase
Solution Approach 1:
Multiple lens units are merged into a single integrated optical module, sharing common components such as the image sensor, processing circuitry, and housing structure. This reduces overall device complexity while maintaining the ability to capture multiple scene types simultaneously.
Solution Approach 2:
The patent arranges multiple lens units in a compact two-dimensional array configuration, allowing them to be stacked or positioned closely together. This spatial arrangement enables multiple lens structures to coexist without significantly increasing the overall device volume or complexity.
3Adaptability or versatility
If multiple lens units are integrated, then the ability to capture multiple scenes is improved, but the manufacturing cost increases
Solution Approach 1:
The patent uses identical or similar lens unit designs repeated multiple times within the device. This homogeneity allows for standardized manufacturing processes, bulk production of identical lens modules, and simplified assembly procedures, thereby reducing per-unit manufacturing costs despite the increased functionality.
