Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensitive film technology is used for imaging self-luminous objects, then image quality can be obtained, but the operation process becomes complicated and imaging time increases
Solution Approach 1:
The patent replaces the mechanical chemical development process of sensitive film with a digital photoelectric conversion system. The imaging sensor directly converts light signals to digital data, eliminating the need for chemical developers and manual processing steps, thus significantly reducing imaging time while maintaining image quality.
Solution Approach 2:
The patent uses a photoelectric conversion element to create a digital copy of the self-luminous object image. This digital copy can be immediately processed, stored, and analyzed without requiring physical film handling or chemical development, thereby reducing both time and operational complexity.
2Ease of manufacture
If camera shooting technology is used with long distance between camera and self-luminous object, then digital images can be stored directly, but optical signal acquisition rate decreases and sensitivity is reduced
Solution Approach 1:
The patent transitions from long-distance optical imaging to contact imaging by placing the imaging sensor in direct proximity to the self-luminous object on the film. This dimensional change from remote to contact imaging dramatically increases optical signal collection efficiency and sensitivity while maintaining digital image storage capabilities.
3Reliability
If traditional imaging systems are used, then imaging function is achieved, but device size becomes large and portability is reduced
Solution Approach 1:
The patent merges the imaging sensor, darkroom environment, and sample holder into a single integrated compact device. By combining these previously separate components into one unified system, the patent achieves full imaging functionality in a portable format that can be easily transported and operated.
Solution Approach 2:
The patent nests the imaging sensor and darkroom environment within a compact housing structure. The self-luminous object is placed within the darkroom space that contains the imaging sensor, creating a nested configuration that maximizes functionality while minimizing overall device size and weight.
