Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If individual optical components (lens, aperture, filter) are housed separately in a compact camera design, then the camera can be made compact, but the manufacturing complexity and alignment precision requirements increase significantly
Solution Approach 1:
The patent combines the lens, aperture, and optical filter into a single integrated optical component. The lens and aperture are formed as one piece, and the optical filter is applied directly to the lens surface, eliminating the need for separate housings and reducing the number of alignment operations required during manufacturing.
Solution Approach 2:
The integrated optical component serves multiple functions simultaneously: the lens focuses light, the aperture controls light intensity and depth of field, and the optical filter selects specific wavelength ranges. This multi-functionality in a single component reduces overall device complexity while maintaining compact dimensions.
2Manufacturing precision
If individual optical components are housed separately with precise spacing, then optical performance can be optimized, but production cost and manufacturing difficulty increase
Solution Approach 1:
By merging the lens and aperture into a single component and applying the optical filter directly to the lens surface, the patent eliminates multiple alignment operations. The integrated design ensures correct spacing and positioning are built-in during component fabrication rather than requiring precise assembly operations.
3Adaptability or versatility
If gaps are maintained between optical components, then component adjustment and adaptability are improved, but the camera size increases and compactness is reduced
Solution Approach 1:
The patent integrates the lens, aperture, and filter into a compact unified structure that eliminates gaps between components. While this reduces physical spacing, the design maintains optical performance by optimizing the integrated component geometry and material properties rather than relying on adjustable gaps.
