Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile X-ray imaging apparatus is equipped with a driving wheel and drive motor to enable movement, then mobility is improved, but stability and safety during movement deteriorate due to lack of proper rotation control
Solution Approach 1:
The patent implements feedback control by using a motor encoder to detect motor rotation speed and driving wheel rotation state detectors (with sensors) to detect wheel rotation state, then feeding this information back to the controller to control the drive motor, ensuring stable and safe movement
Solution Approach 2:
The patent replaces simple mechanical wheel-motor connection with an intelligent control system that uses sensors and controllers to detect and control the rotation state of the driving wheel, substituting mechanical intuition with electronic sensing and control
2Reliability
If a dual safety control system with multiple sensors is implemented to detect driving wheel rotation state, then safety and stability are improved, but device complexity increases
Solution Approach 1:
The patent uses feedback from multiple sensors (motor encoder and driving wheel rotation state detectors) to continuously monitor the driving wheel rotation state and provide information to the controller for safety control
Solution Approach 2:
The patent introduces a controller as an intermediary that receives detection information from both the motor encoder and driving wheel rotation state detectors, processes this information, and controls the drive motor to coordinate between multiple sensing systems
