Solution Overview
Problem
Existing biological sample detection systems rely on external light sources and optical components, which increase complexity and size, making it desirable to develop methods that do not require these components for efficient detection.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external light sources and optical components are used to detect biological samples, then detection capability is achieved, but device complexity and size increase
Solution Approach 1:
The patent extracts and eliminates the external light source from the detection system. The container wall itself is transformed to emit light directly, removing the need for separate excitation light sources and associated optical components, thereby reducing device complexity while maintaining detection capability
Solution Approach 2:
The patent merges the container wall with the light emission function. The container wall is designed to emit light directly, combining the previously separate functions of container and light source into a single integrated component, reducing overall system complexity
2Reliability
If external light sources and optical components are used to detect biological samples, then detection capability is achieved, but device size increases
Solution Approach 1:
The patent removes the external light source and optical components from the system, extracting these separate elements and eliminating their volume requirements. The detection function is achieved using only the container wall and photosensitive material, significantly reducing device size
Solution Approach 2:
The container wall is merged with the light emission function, eliminating the need for separate light source housing and optical component mounting space, thereby reducing the overall device volume
3Loss of energy
If luminescent light is detected in the vicinity of the biological sample, then light loss is reduced, but light collection efficiency must be enhanced
Solution Approach 1:
The patent applies local quality by making the container wall photosensitive directly at the location where light collection is needed. The wall material itself is designed to be sensitive to the luminescent light emitted by the biological sample, enabling efficient local detection without light loss
Solution Approach 2:
The container wall serves as an intermediary between the biological sample and the photosensitive material. It both contains the sample and directly detects the luminescent light, eliminating the need for separate light collection optics and reducing light loss
