Engineering Contradiction Analysis
1Reliability
If fixed temperature thresholds are used to activate cooling systems, then the equipment is protected against overheating, but the cooling systems experience unnecessary wear and energy consumption increases
Solution Approach 1:
The patent implements dynamic cooling control by continuously monitoring actual temperature measurements and adjusting cooling activation thresholds in real-time based on measured machine aging data. This replaces fixed static thresholds with adaptive dynamic thresholds that optimize cooling activation timing, reducing unnecessary cooling cycles and energy consumption while maintaining equipment protection.
Solution Approach 2:
The system incorporates feedback mechanisms by measuring actual temperature values during operation and using this information to adjust cooling control decisions. The feedback loop includes monitoring machine aging indicators and comparing them against target aging rates, enabling the system to learn from actual performance and optimize cooling activation patterns to minimize energy waste.
2Duration of action of stationary object
If cooling systems are activated frequently to protect equipment, then the equipment lifespan is extended, but the cooling system wear increases
Solution Approach 1:
The patent uses dynamic adjustment of cooling thresholds based on real-time temperature measurements and machine aging data. This allows the system to extend equipment lifespan through targeted cooling activation only when genuinely needed, rather than frequent unnecessary activations, thereby reducing cooling system wear and extending its operational life.
Solution Approach 2:
The system changes operational parameters by adjusting cooling activation thresholds dynamically based on measured temperature values and machine aging indicators. This parameter adaptation enables optimal balancing between equipment protection and cooling system preservation, activating cooling only when actual conditions warrant it.
3Loss of energy
If dynamic cooling control based on real-time temperature and aging data is implemented, then energy consumption is reduced and equipment lifespan is extended, but the control system complexity increases
Solution Approach 1:
The patent implements a multi-functional control system that simultaneously performs temperature monitoring, machine aging assessment, dynamic threshold adjustment, and cooling control optimization. This universal controller handles multiple functions through integrated algorithms that analyze temperature data and aging indicators to generate optimized cooling commands, reducing the need for separate dedicated systems for each function.
