Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional solutions use metal rings or large cases to provide auxiliary focusing functions, then lens flexibility is improved, but device complexity and mechanical burden increase
Solution Approach 1:
The lens board is divided into multiple receivers that can independently hold different auxiliary lenses, allowing the system to provide multiple lens options through a single modular component rather than requiring separate mechanical attachments for each lens type
Solution Approach 2:
The lens board serves multiple functions: it provides mechanical support for auxiliary lenses, enables rotation to align different lenses with the camera, and incorporates circuitry for lens identification and optical correction, replacing the need for multiple separate mechanical solutions
2Adaptability or versatility
If conventional solutions provide auxiliary focusing functions through mechanical attachments, then some lens choices are available, but ease of operation deteriorates due to cumbersome mechanics
Solution Approach 1:
The lens board incorporates rotational capability that allows users to dynamically switch between different auxiliary lenses by simply rotating the board to different positions, making lens selection as easy as rotating a dial rather than manually attaching different lenses
Solution Approach 2:
The circuitry within the lens board automatically identifies the installed lenses and communicates with the mobile device to enable appropriate focusing and image correction, eliminating the need for users to manually configure settings when changing lenses
3Device complexity
If conventional camera systems use a fixed built-in lens, then device simplicity is maintained, but adaptability for different lens types is limited
Solution Approach 1:
The auxiliary lenses are nested within the lens board structure, which itself attaches to the mobile device. This nested arrangement allows multiple lenses to be housed in a compact form factor without significantly increasing the overall device size or complexity
Solution Approach 2:
The lens board acts as an intermediary component between the mobile device and various auxiliary lenses, providing a standardized interface that enables lens versatility while maintaining the simplicity of the core device architecture
