Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple transmission circuits are activated to maximize data throughput, then transmission data throughput is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic adjustment of transmission circuit quantity based on real-time packet transmission rate measurements. The system transitions from a static configuration where multiple circuits are always active to a dynamic configuration where the number of active circuits adapts to current traffic conditions, resolving the contradiction between maintaining high throughput capability and reducing power consumption during low-traffic periods
Solution Approach 2:
The system changes the operational parameters of the transmission system by adjusting the number of active transmission circuits based on measured packet transmission rates and calculated PER values. This parameter adjustment allows the system to optimize the balance between throughput and power consumption by selecting appropriate circuit configurations matching current traffic demands
2Use of energy by moving object
If the transmission circuit number is decreased to reduce power consumption, then power consumption is reduced, but transmission reliability may deteriorate
Solution Approach 1:
The patent implements a feedback mechanism where the system continuously measures packet transmission rates, calculates PER values, and uses this feedback information to intelligently adjust the number of active transmission circuits. This closed-loop control ensures that circuit reduction decisions are based on actual transmission performance and error conditions, preventing reliability deterioration while achieving power savings
Solution Approach 2:
The system performs self-adjustment by automatically measuring its own transmission characteristics, calculating error rates, and determining optimal circuit configurations without external intervention. This self-service capability allows the system to autonomously balance power consumption and reliability based on real-time operational conditions
