Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If the battery is charged continuously without temperature control, then the battery capacity is maintained, but the temperature increases causing functional deterioration and damage
Solution Approach 1:
The patent implements a feedback control mechanism where temperature detection sections continuously monitor the battery temperature, and the control section adjusts charging based on detected temperature values. When the battery temperature exceeds a predetermined threshold during charging, the control section automatically stops charging to prevent overheating, thus resolving the contradiction between continuous charging and temperature control.
Solution Approach 2:
The patent employs preliminary action by detecting temperature before dangerous overheating occurs and preemptively stopping the charging process. The temperature detection sections monitor battery temperature in advance, and when the threshold is approached, the control section halts charging before significant damage can occur, preventing rather than reacting to the harmful temperature increase.
2Duration of action of stationary object
If the communication process section operates continuously without temperature control, then the communication functionality is maintained, but the temperature increases causing functional deterioration and damage
Solution Approach 1:
The control section receives continuous temperature feedback from the temperature detection sections and adjusts the operation of the communication process section accordingly. When the battery temperature exceeds the predetermined threshold during communication operations, the control section stops the communication process to prevent overheating, thus maintaining communication functionality within safe temperature limits.
Solution Approach 2:
The system performs preliminary temperature monitoring and preemptively stops communication operations before dangerous overheating occurs. The temperature detection sections continuously monitor battery temperature during communication operations, and when the threshold is approached, the control section halts operations in advance to prevent functional deterioration.
3Device complexity
If no temperature detection mechanism is implemented, then the device structure remains simple, but temperature control and stability cannot be ensured
Solution Approach 1:
The patent introduces temperature detection sections as intermediary components that bridge the gap between the battery/communication process section and the control section. These detection sections provide temperature information to the control section, enabling temperature-based control decisions without requiring complex direct monitoring of the entire system, thus balancing structural simplicity with reliable temperature control.
