Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless transmission is used to enable cable-free operation, then ease of operation is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts the data transmission rate based on real-time temperature conditions. When the processing unit exceeds the maximum operating temperature, the system automatically reduces the data rate from the first data rate to the second data rate, enabling adaptive power management while maintaining wireless operation
Solution Approach 2:
The invention changes the transmission parameter (data rate) from a fixed value to a variable value based on thermal conditions. By switching between two predefined data rates, the system optimizes the balance between wireless performance and power consumption/heat generation
2Productivity
If high data transmission rate is used, then productivity is improved, but temperature increases
Solution Approach 1:
The system implements dynamic data rate adjustment based on temperature feedback. The data transmission rate is not fixed but changes according to the processing unit's thermal state, automatically reducing the rate when temperature exceeds thresholds to prevent overheating
Solution Approach 2:
The invention incorporates a feedback mechanism where the temperature of the processing unit is monitored and used to control the data transmission rate. The system continuously adjusts the transmission rate based on real-time temperature measurements, creating a closed-loop thermal management system
3Productivity
If processing speed is increased, then productivity is improved, but heat generation increases
Solution Approach 1:
The system changes the operational parameters of the processing unit based on thermal conditions. By adjusting the data rate parameter, the system controls the processing load and corresponding heat generation, maintaining productivity within thermal safety limits
