Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If charging is performed without temperature management, then charging speed and productivity are improved, but battery deterioration accelerates and reliability decreases
Solution Approach 1:
The system performs preliminary temperature assessment before initiating charging by acquiring temperature information and deterioration information of the storage battery. Based on this preliminary evaluation, the system determines appropriate temperature conditions and decides whether to proceed with charging, thereby preventing deterioration before it occurs while enabling charging when conditions are suitable.
Solution Approach 2:
The system dynamically adjusts charging parameters based on the storage battery's temperature and deterioration state. By changing temperature conditions as a control parameter, the system optimizes charging speed when the battery is in good condition while preventing charging when temperature conditions would cause deterioration, thus resolving the contradiction between productivity and reliability.
2Reliability
If temperature conditions are strictly controlled to prevent deterioration, then battery reliability is improved, but charging efficiency and productivity decrease
Solution Approach 1:
The system applies different temperature condition standards to different batteries based on their individual deterioration states. Rather than imposing a uniform restrictive temperature limit on all batteries, the system evaluates each battery's specific condition and determines appropriate temperature conditions individually, allowing efficient charging for batteries in good condition while protecting deteriorated batteries.
Solution Approach 2:
The system dynamically determines temperature conditions based on real-time assessment of temperature information and deterioration information. The temperature conditions are not fixed but adapt to the battery's current state, enabling the system to maximize charging efficiency when appropriate while preventing deterioration when necessary, thus resolving the contradiction between reliability and productivity.
3Reliability
If temperature information is acquired for all batteries, then charging safety and reliability are improved, but system complexity and measurement requirements increase
Solution Approach 1:
The information processing apparatus performs multiple functions using a unified approach: it acquires temperature information, acquires deterioration information, determines temperature conditions, and extracts charge targets all through a single integrated system. This multi-functional design improves reliability through comprehensive monitoring while avoiding the complexity of separate specialized systems for each function.
