Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If specialized detection equipment is used to detect interfering signals, then detection capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent applies universality by enabling communication devices to perform both their primary communication function and interference detection function. Existing communication devices monitor interfering signals in addition to their normal operation, eliminating the need for separate specialized detection equipment. This multi-functional approach resolves the contradiction by maintaining detection capability while reducing device complexity.
Solution Approach 2:
The communication devices monitor and detect interfering signals as part of their own operational routine, using their existing receivers and processing capabilities. The devices serve their own detection needs without requiring external specialized equipment, thereby improving detection capability while avoiding increased complexity.
2Measurement precision
If dedicated receivers are deployed for interference monitoring, then detection accuracy is improved, but resource consumption increases
Solution Approach 1:
Existing communication devices are made multi-functional by enabling them to perform interference monitoring in addition to their primary communication tasks. This eliminates the need for dedicated receivers, reducing the quantity of components while maintaining detection accuracy through the use of existing device capabilities.
Solution Approach 2:
The communication devices utilize their own built-in receivers and processing units to monitor interfering signals, serving their own detection requirements without requiring additional dedicated receivers. This self-service approach reduces resource consumption while maintaining accurate detection.
3Reliability
If continuous monitoring of all frequency bands is performed, then detection completeness is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic monitoring where communication devices check for interfering signals at scheduled intervals rather than continuously. This periodic action maintains detection completeness by performing regular checks across all frequency bands while significantly reducing energy consumption compared to continuous monitoring.
Solution Approach 2:
The monitoring approach is made dynamic by adjusting monitoring intensity and frequency based on network conditions and detected interference levels. When interference is detected, monitoring becomes more intensive; when the network is stable, monitoring can be reduced, optimizing the balance between detection completeness and energy consumption.
