Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a gas sensor is installed inside the electronic device to detect battery gas leakage, then detection capability is improved, but device complexity increases
Solution Approach 1:
The gas sensor is integrated into the existing sensor module that is already installed inside the electronic device, combining multiple sensing functions into a single component. This approach improves gas leakage detection capability while minimizing the increase in device complexity by utilizing existing structural space and circuit resources.
2Reliability
If real-time gas detection is implemented, then safety is improved, but energy consumption increases
Solution Approach 1:
The system implements periodic gas detection at predetermined time intervals rather than continuous monitoring. The processor controls the sensor to detect gas concentration periodically, and only triggers charging operation adjustments when gas concentration exceeds the predetermined threshold. This periodic action maintains battery safety while significantly reducing energy consumption compared to continuous monitoring.
3Stability of the object's composition
If charging operation is restricted based on gas detection, then battery stability is improved, but productivity decreases
Solution Approach 1:
The charging operation is dynamically adjusted based on real-time gas concentration detection. When gas concentration exceeds the predetermined threshold, the processor restricts charging operations to prevent battery instability. When gas concentration is within acceptable limits, normal charging operations resume. This dynamic adjustment maintains battery stability while maximizing charging productivity under safe conditions.
