Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual inspection methods are used to check braking systems, then comprehensive checking can be performed, but the process is time-consuming and labor-intensive
Solution Approach 1:
The braking system performs self-diagnosis through automated pressure application and sensor monitoring. The control unit automatically controls the brake reservoirs, monitors pressure levels, and determines brake engagement status without requiring manual inspection rounds, enabling the system to check itself
Solution Approach 2:
Manual mechanical inspection by inspectors is replaced by an automated electronic control system with pressure sensors and a control unit that electronically monitors and evaluates brake system status, substituting human labor with automated sensing and control mechanisms
2Measurement precision
If multiple inspection rounds are performed to verify brake engagement and disengagement, then accurate verification is achieved, but the process becomes cumbersome and inefficient
Solution Approach 1:
The control unit continuously monitors pressure in the brake reservoirs throughout the testing process, maintaining continuous awareness of brake status rather than performing discrete inspection rounds. This continuous monitoring enables accurate verification while eliminating the need for multiple separate inspection cycles
Solution Approach 2:
Pressure sensors provide continuous feedback to the control unit about the actual pressure levels in the brake reservoirs. The control unit uses this feedback to automatically determine when brakes are engaged or disengaged and to verify test results, creating a closed-loop system that ensures accuracy without requiring manual verification rounds
3Manufacturing precision
If inspectors manually control compressed air units for pressure testing, then precise pressure control is achieved, but the process requires significant human involvement and time
Solution Approach 1:
The control unit automatically controls the brake reservoirs to apply and release brakes based on predetermined pressure levels. The system self-regulates the pressure application process without requiring inspector intervention, maintaining precise pressure control while eliminating manual operation
Solution Approach 2:
Manual control of compressed air units by inspectors is replaced by an automated control unit that electronically manages pressure application. The control unit precisely controls pressure levels and timing, substituting manual mechanical control with automated electronic control for both precision and simplicity
