Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If continuous high-precision sensing measurements are performed, then sensing accuracy is improved, but resource consumption and device complexity increase
Solution Approach 1:
The patent segments the sensing measurement process into two distinct stages: a first sensing stage using a first sensing signal for basic detection, and a second sensing stage using a second sensing signal for high-precision measurement. This segmentation allows the system to perform continuous monitoring with low complexity while triggering high-precision measurements only when necessary, thus resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
The patent implements periodic sensing measurements with different signal configurations. The first sensing signal is measured continuously or periodically for basic detection, while the second sensing signal is measured periodically only when triggered by specific conditions. This periodic action with varying intensity resolves the contradiction by maintaining acceptable accuracy through regular monitoring while avoiding continuous high-precision measurements that would increase complexity.
2Measurement precision
If continuous high-precision sensing measurements are performed, then sensing accuracy is improved, but power consumption increases
Solution Approach 1:
The patent segments the sensing measurement process into two distinct stages: a first sensing stage using a first sensing signal for basic detection, and a second sensing stage using a second sensing signal for high-precision measurement. This segmentation allows the system to perform continuous monitoring with low complexity while triggering high-precision measurements only when necessary, thus resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
The patent changes key parameters of the sensing signal based on the measurement stage: the first sensing signal uses lower bandwidth and simpler configuration for continuous monitoring, while the second sensing signal uses higher bandwidth and more complex configuration for high-precision measurements. This parameter changes approach allows the system to maintain acceptable accuracy during normal operation while consuming minimal power, and only activates high-power high-precision measurements when necessary.
3Measurement precision
If resource allocation is increased for sensing signals, then sensing precision is improved, but resource overhead increases
Solution Approach 1:
The patent segments the sensing measurement process into two distinct stages: a first sensing stage using a first sensing signal for basic detection, and a second sensing stage using a second sensing signal for high-precision measurement. This segmentation allows the system to perform continuous monitoring with low complexity while triggering high-precision measurements only when necessary, thus resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
The patent applies partial action by using a simplified first sensing signal for continuous monitoring and basic detection, reserving the more resource-intensive second sensing signal for specific high-precision measurement needs. This partial action approach ensures that high resource allocation is applied only when necessary for high precision, rather than continuously, thus resolving the contradiction between sensing precision and resource overhead.
