Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the battery is charged to a high charge level before storage, then the device can operate longer after storage, but the battery integrity deteriorates due to overcharge and degradation
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the battery charge level based on storage duration. The system calculates optimal charge levels that vary with storage time, transitioning from high charge for short-term storage to partial charge for long-term storage. This resolves the contradiction by finding the optimal charge parameter for each storage scenario, preventing both insufficient operation and battery degradation.
Solution Approach 2:
The patent implements preliminary action by pre-calculating and pre-setting the optimal charge level before the storage period begins. The system determines the appropriate charge level in advance based on the intended storage duration and configures the battery accordingly, ensuring the device is ready for extended operation without risking battery integrity during storage.
2Reliability
If the battery is charged to a low charge level before storage, then the battery integrity is maintained, but the device cannot operate after storage
Solution Approach 1:
The patent resolves this contradiction through parameter changes by establishing a minimum charge level threshold that varies with storage duration. For short-term storage, the system maintains higher charge levels to ensure operation, while for long-term storage, it reduces the charge level to preserve battery integrity. This dynamic parameter adjustment ensures both operability and battery health across different storage scenarios.
3Duration of action of moving object
If additional charge is provided to the battery during storage, then the device can operate after storage, but the battery degradation accelerates
Solution Approach 1:
The patent applies preliminary anti-action by preemptively preventing the harmful effect of charge-induced degradation before it can occur. The system calculates and enforces a minimum charge level that is sufficient for post-storage operation but explicitly prevents excessive charging during storage. This anti-action approach blocks the degradation pathway while ensuring operational readiness.
Solution Approach 2:
The patent converts the potentially harmful effect of charge accumulation into a beneficial outcome by precisely controlling the charge level to the optimal minimum. Instead of allowing uncontrolled charging that causes degradation, the system uses the charge as a beneficial resource, maintaining it at the exact level needed for operation after storage, thereby transforming a potential harm into a benefit.
