Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driving power of the transmission device is increased to maintain transmission quality at higher temperature, then the transmission ability is improved, but the power consumption is increased
Solution Approach 1:
The patent applies dynamics by making the driving power adjustable based on temperature conditions. The transmission device dynamically changes its operating parameters - using higher driving power at elevated temperatures to maintain transmission quality, and reducing driving power at lower temperatures to minimize power consumption. This dynamic adaptation resolves the contradiction between maintaining reliability and reducing energy use.
Solution Approach 2:
The patent implements parameter changes by modifying the driving power parameter according to temperature. The system monitors temperature conditions and adjusts the driving power parameter accordingly - increasing it when temperature rises to compensate for degraded transmission characteristics, and decreasing it when temperature is low to reduce power consumption. This parameter adaptation strategy directly addresses the technical contradiction.
2Use of energy by moving object
If the driving power of the transmission device is decreased to reduce power consumption at lower temperature, then the power consumption is reduced, but the transmission ability is degraded
Solution Approach 1:
The system uses dynamics to adapt driving power to temperature conditions. At lower temperatures where transmission characteristics are already good, the system dynamically reduces driving power to minimize power consumption while maintaining adequate transmission quality. This dynamic adjustment prevents unnecessary energy waste when high transmission ability is not critical.
Solution Approach 2:
The patent applies parameter changes by adjusting the driving power parameter based on temperature feedback. When temperature is low and transmission quality is naturally high, the system decreases the driving power parameter to reduce power consumption. This parameter modulation resolves the contradiction between energy efficiency and transmission capability at favorable temperature conditions.
3Reliability
If constant driving power is used regardless of temperature, then the transmission ability is maintained, but the power consumption cannot be optimized at lower temperature
Solution Approach 1:
The patent implements dynamics by transitioning from static constant driving power to dynamic temperature-dependent driving power. The system continuously adapts its operating point based on temperature measurements, adjusting driving power to match actual transmission requirements. This dynamic behavior provides both maintained transmission quality and optimized power consumption across different temperature conditions.
Solution Approach 2:
The system applies parameter changes by making the driving power parameter variable rather than fixed. The driving power parameter is adjusted as a function of temperature - increased at high temperatures to compensate for degradation, and decreased at low temperatures to optimize energy efficiency. This parameter variability directly addresses the lack of temperature adaptation in constant power systems.
