Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data resolution is increased to improve transmission quality, then transmission reliability is improved, but transmission time increases and power consumption increases
Solution Approach 1:
The patent implements dynamic adjustment of data resolution based on real-time transmission characteristics. The processing unit determines optimal data resolution by considering current wireless channel conditions, allowing the system to adapt between high resolution (for good channels) and low resolution (for poor channels), thereby resolving the contradiction between transmission quality and transmission time
Solution Approach 2:
The system changes the data resolution parameter according to transmission characteristics. By modifying this key parameter dynamically, the system optimizes the balance between maintaining transmission quality and reducing transmission time under varying channel conditions
2Reliability
If data resolution is increased to improve transmission quality, then transmission reliability is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts data resolution based on real-time transmission characteristics and communication quality information. When channel conditions are poor, lower resolution is used to reduce power consumption while maintaining acceptable quality. When conditions are good, higher resolution is used to maximize quality without unnecessary power waste
Solution Approach 2:
The processing unit modifies the data resolution parameter according to transmission characteristics, enabling the system to optimize power consumption by using only the necessary resolution for current channel conditions rather than consistently using high resolution
3Productivity
If data is compressed to reduce transmission time, then transmission speed is improved, but data loss increases
Solution Approach 1:
The system adjusts data resolution parameter to control the degree of compression. By selecting appropriate resolution levels based on transmission characteristics, the system achieves optimal balance between compression ratio (affecting speed) and data fidelity (affecting data loss), preventing excessive compression while maximizing transmission efficiency
4Adaptability or versatility
If data resolution is dynamically adjusted to optimize transmission, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system uses feedback from transmission characteristics and communication quality information to dynamically adjust data resolution. The processing unit receives feedback about channel conditions and automatically modifies resolution settings, providing adaptability through a relatively simple feedback-driven mechanism rather than complex multi-layer processing
