Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation and coordination among multiple operators is used for filling and bleeding brake fluid, then the process can be completed, but labor intensity and time consumption increase significantly
Solution Approach 1:
The system enables self-service operation where the brake fluid filling and bleeding process is automated through electronic control. The ECU receives instructions and automatically controls the brake pedal actuation and bleed screw operation, eliminating the need for multiple operators and significantly reducing labor intensity and time consumption.
Solution Approach 2:
The patent replaces manual mechanical operations with an electronic control system. The ECU electronically controls the brake pedal actuator and bleed screw mechanism, substituting human physical operations and coordination with automated electronic commands, thereby reducing labor intensity and operation time.
2Reliability
If manual coordination among multiple operators is used, then brake fluid can be filled and bled, but human error increases leading to incomplete fluid replacement and air exhaustion
Solution Approach 1:
The system incorporates feedback mechanisms where the ECU monitors the bleeding process and automatically adjusts the operation based on detected conditions. The system receives feedback from pressure sensors and flow detectors to determine when air exhaustion is complete and when fluid replacement is sufficient, ensuring reliability while simplifying operation.
Solution Approach 2:
The automated system performs the complex coordination tasks itself without requiring human operators to manage multiple actions. The ECU independently controls the timing and sequence of brake pedal actuation and bleed screw operation, eliminating human error while keeping the interface simple for the user.
3Productivity
If automated control is implemented using ECU and electronic signals, then labor intensity and time cost are reduced, but device complexity increases
Solution Approach 1:
The ECU performs multiple functions including controlling the brake pedal actuator, managing the bleed screw operation, monitoring system conditions, and determining when the bleeding process is complete. By using an existing multi-functional control unit, the system achieves high productivity without proportionally increasing device complexity.
Solution Approach 2:
The wireless communication module acts as an intermediary between the user interface and the ECU, translating simple user commands into complex automated sequences. This intermediary layer simplifies the user interface while maintaining the automated efficiency, effectively managing the complexity without exposing it to the operator.
4Ease of operation
If wireless control signals are used to actuate the bleed screw, then manual operation is simplified and standardized, but device complexity increases
Solution Approach 1:
The patent replaces manual mechanical operation of the bleed screw with wireless electronic control. The wireless receiver receives commands and the ECU automatically actuates the bleed screw through an electronic actuator, standardizing the operation while using existing wireless communication technology to minimize the increase in system complexity.
