Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the charger is connected to the electrical power supply network to recharge the battery, then the battery can be recharged, but the power supply to the processing unit is abruptly cut off, causing malfunctions and information loss
Solution Approach 1:
The power supply system is segmented into multiple independent paths: one path for battery charging through the charger, and another path for processing unit power supply through the voltage converter. The controllable opening and closing device selectively connects or disconnects these paths, allowing the processing unit to remain powered during battery charging operations.
Solution Approach 2:
The controllable opening and closing device acts as an intermediary element that mediates between the battery, voltage converter, and processing unit. It controls the flow of electrical power, enabling the processing unit to draw power from the voltage converter even when the battery is being charged by the external power supply network.
2Ease of operation
If the user does not observe the battery charging process as described in the instruction manual, then the charging may be interrupted or improper, but the user has no adequate information feedback about charge status
Solution Approach 1:
The processing unit continuously monitors the battery charging process and provides real-time feedback to the user through the display device. It displays information such as charging status, charge level, and any deviations from proper charging procedures. The system can also send notifications to remote devices, ensuring users have adequate information feedback about charge status and compliance with charging instructions.
3Use of energy by moving object
If the charger connection causes abrupt power cutoff to the processing unit, then battery charging can proceed, but data integrity and operational continuity are compromised
Solution Approach 1:
The system maintains continuous operation of the processing unit during battery charging by providing an uninterrupted power supply through the voltage converter. The controllable opening and closing device ensures that the processing unit remains powered throughout the charging process, allowing data processing, monitoring, and control functions to continue without interruption, thereby preserving data integrity and operational continuity.
