Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If UWB systems are implemented in complex environments with signal reflection and diffraction, then the system can operate in real-world conditions, but extensive site-specific optimization and installation procedures are required
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing optimized circuitry configurations and algorithms for various environmental conditions in a lookup table. During installation, the system simply queries the pre-computed results based on measured environmental parameters, eliminating the need for time-consuming real-time optimization and extensive installation procedures while maintaining adaptability to different environments
2Reliability
If optimized circuitry and algorithms are developed for each specific environment, then UWB system performance is improved, but the development and deployment process becomes time-consuming
Solution Approach 1:
The patent resolves this contradiction by performing the complex optimization work in advance and storing the results in pre-computed lookup tables. The system measures environmental parameters, queries the pre-stored optimized configurations, and deploys them immediately. This approach maintains high system performance through environment-specific optimization while enabling rapid deployment without repeated real-time optimization
Solution Approach 2:
The patent uses copying by creating pre-computed lookup tables that contain optimized circuitry configurations and algorithms for various environmental conditions. Instead of performing complex optimization calculations during each deployment, the system copies the appropriate pre-optimized configuration from the lookup table based on measured environmental parameters, significantly accelerating the deployment process while maintaining performance
