An optical detection device with a shield cover that can be controlled to open or close, equipped with sensors and actuators to prevent external light and maintain a controlled environment, ensuring accurate sensing and safety by blocking ambient light and potential viral exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cartridge placing portion is left open for easy access, then ease of operation is improved, but ambient light interferes with optical sensing and specimen volatilization occurs
Solution Approach 1:
The shield cover is designed to be movable between open and closed positions, allowing the system to dynamically adapt between ease of access and protection from ambient light. The cover closes during optical sensing to block ambient light while remaining open during cartridge insertion/removal for operational convenience.
Solution Approach 2:
The shield cover acts as an intermediary element between the open environment and the sensitive optical sensing area. It selectively blocks ambient light during detection while allowing specimen access during loading, mediating between the conflicting requirements of accessibility and measurement precision.
2Measurement precision
If the shield cover is closed to block ambient light, then detection accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
The shield cover transitions from a static barrier to a dynamic component that automatically opens during cartridge insertion and closes during optical sensing. This dynamic behavior resolves the contradiction by providing protection only when needed while maintaining operational accessibility when required.
Solution Approach 2:
The shield cover operates autonomously based on the detection cycle, opening automatically when a cartridge is inserted and closing automatically when optical sensing is required. This self-service mechanism eliminates the need for manual intervention to manage the cover, maintaining both detection accuracy and operational ease.
3Ease of operation
If the opening remains open for cartridge access, then ease of operation is improved, but specimen volatilization and viral exposure risk increase
Solution Approach 1:
The shield cover dynamically transitions from an open state during cartridge loading to a closed state during detection, creating a protective enclosure that prevents specimen volatilization and viral exposure while maintaining ease of cartridge access when needed.
Solution Approach 2:
The shield cover serves as a protective intermediary that isolates the specimen from the external environment during detection, preventing volatilization and exposure risks while allowing convenient cartridge insertion and removal during loading operations.

AI summary
An optical detection device includes a base, a cartridge placing portion, a shield cover, a processor, and an optical sensor. The base includes an opening. The cartridge placing portion is located in the base, and is in communication with the opening. The shield cover is configured to open or close the opening. When the optical sensor is actuated, the shield cover closes the opening to prevent external ambient light from entering the opening to affect the optical sensor during sensing.
