Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hydraulic power systems operate without monitoring mechanisms, then the system structure remains simple, but temperature and pressure management become inefficient leading to potential damage
Solution Approach 1:
The controller is configured to enter a diagnostic mode by receiving a signal from the button assembly when the hydraulic system is not operating, allowing error code retrieval and display before operational issues arise. This preliminary diagnostic capability enables proactive identification and resolution of potential problems.
Solution Approach 2:
The system incorporates feedback mechanisms through the button assembly that provides tactile and visual feedback to indicate system state. The controller retrieves and displays error codes through the user interface, creating a feedback loop that informs operators of system conditions and enables corrective action.
2Difficulty of detecting and measuring
If the system lacks diagnostic capabilities, then the device complexity is reduced, but error detection and maintenance capabilities are inadequate
Solution Approach 1:
The controller stores error codes in memory during normal operation and retrieves them upon request through the diagnostic mode. This preliminary capture and storage of error information enables comprehensive diagnostic capability without requiring complex real-time monitoring during operation.
Solution Approach 2:
The button assembly serves as an intermediary interface between the user and the controller's diagnostic functions. By pressing the button in specific sequences, users can trigger diagnostic modes and retrieve error codes without directly accessing the controller's internal systems, simplifying the interaction while maintaining comprehensive diagnostics.
3Temperature
If cooling fan operation is not optimized, then the control logic remains simple, but temperature regulation efficiency decreases risking overheating damage
Solution Approach 1:
The cooling fan operation is dynamically adjusted based on real-time temperature conditions. The controller monitors temperatures from multiple sensors and adjusts fan speed and operation mode accordingly, transitioning between different operational states to optimize cooling efficiency while preventing overheating.
Solution Approach 2:
The cooling system operates in periodic cycles, alternating between active cooling phases when temperature thresholds are exceeded and idle phases when temperatures are within acceptable ranges. This periodic operation optimizes energy consumption while maintaining effective temperature control.

Implementation Method 1
The fan is powered in the first one mode when the motor is in an on mode and a first temperature condition is met. The first temperature condition includes an ambient temperature or a motor controller bridge temperature. The fan is powered in the second on mode when the oil temperature switch is in an open position or when the motor controller bridge temperature is above a first motor controller bridge threshold.
Implementation Method 2
The method includes actuating the button and releasing the button after a first time interval, and entering a diagnostic state. The method further includes retrieving a code and displaying the code by turning on the emitter in a first pattern.
