Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual decontamination mode is used, then operational flexibility is maintained, but decontamination efficiency is low and personnel safety is compromised
Solution Approach 1:
The patent replaces manual mechanical decontamination operations with an automated robotic system equipped with cleaning heads. The robot uses servo motors to control the cleaning mechanism, substituting human operators with an automated mechanical system that performs decontamination tasks more efficiently and safely.
Solution Approach 2:
The decontamination robot performs self-service by autonomously navigating to contaminated areas and executing cleaning operations without human intervention. The system includes self-contained cleaning mechanisms that automatically remove radioactive substances from surfaces and personnel.
2Speed
If automated cleaning device is introduced, then decontamination speed increases, but device complexity increases
Solution Approach 1:
The cleaning device is segmented into modular components including a robot body, cleaning head module, protective housing, and driving mechanisms. Each module performs a specific function and can be independently controlled or maintained, reducing overall system complexity while maintaining high decontamination speed.
Solution Approach 2:
The cleaning head is designed with dynamic reciprocating motion capabilities, allowing it to move up and down automatically during operation. This dynamic cleaning action increases decontamination efficiency without requiring complex multi-axis positioning systems, as the motion is achieved through a simplified mechanical linkage.
3Reliability
If cleaning mechanism operates continuously, then decontamination effectiveness improves, but risk of harmful substance contamination increases
Solution Approach 1:
The cleaning head features multi-layer brush structures with different materials suited for specific cleaning tasks. The protective housing is designed with localized sealing at critical interfaces where the cleaning head connects to the robot body, preventing harmful substances from penetrating into the driving mechanism while allowing continuous operation.
Solution Approach 2:
The protective housing acts as an intermediary barrier between the cleaning head and the internal driving mechanism. It allows the cleaning function to operate continuously while blocking harmful radioactive substances from reaching and contaminating the mechanical components, thus maintaining both effectiveness and reliability.
