Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If batteries are used frequently for charging and discharging to increase terminal endurance, then the battery may swell and cause safety accidents
Solution Approach 1:
The patent implements a feedback mechanism by continuously monitoring battery temperature and usage history, then adjusting charging/discharging strategies based on accumulated temperature data. The control unit records temperature parameters over time and uses this feedback to prevent unsafe operating conditions, resolving the contradiction between extended usage and safety.
Solution Approach 2:
The patent applies preliminary action by proactively monitoring battery temperature parameters before swelling occurs. By tracking cumulative temperature exposure in advance and predicting potential safety issues, the system can prevent harmful conditions rather than reacting after damage has occurred.
2Reliability
If multiple batteries are used in turn to prevent swelling, then the charging and discharging control becomes complex
Solution Approach 1:
The patent simplifies control by changing from complex multi-parameter decision-making to a focused temperature-based parameter system. By monitoring cumulative temperature exposure as the key parameter and using predetermined thresholds, the system manages multiple batteries through a simple, unified temperature criterion rather than complex switching logic.
Solution Approach 2:
The control unit automatically manages battery selection and charging/discharging decisions based on temperature parameters without requiring complex external control. The system serves itself by autonomously monitoring temperature, comparing against thresholds, and adjusting battery usage patterns independently.
3Productivity
If preferential charging or discharging is performed based on battery power or voltage, then the battery safety is not considered emphatically
Solution Approach 1:
The patent changes the primary control parameter from power/voltage (efficiency-based) to temperature (safety-based). By using cumulative temperature exposure as the decision parameter, the system prioritizes safety while maintaining reasonable efficiency through temperature-aware charging/discharging strategies.
Solution Approach 2:
The system implements temperature-based feedback control that continuously monitors thermal conditions and adjusts charging/discharging operations accordingly. This feedback mechanism ensures safety considerations are embedded in the control logic rather than being secondary to efficiency goals.
