Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single radio type is used, then device complexity is reduced, but the ability to optimize multiple performance objectives simultaneously is limited
Solution Approach 1:
The system employs multiple radio types (narrowband and ultra-wideband) within a single wireless device, enabling the device to perform multiple communication functions simultaneously. Each radio type is optimized for different performance objectives, allowing the system to adapt to various communication scenarios and optimize multiple objectives without increasing overall system complexity through intelligent radio selection and switching mechanisms.
2Use of energy by moving object
If transmitted power is reduced for low-power design, then power consumption is minimized, but communication range and reliability are reduced
Solution Approach 1:
The system dynamically changes the transmission parameter (radio type selection) based on communication requirements. When low power consumption is needed, the system selects the narrowband radio with lower power consumption. When communication range and reliability are prioritized, the system switches to the ultra-wideband radio that provides better performance despite higher power consumption, thus optimizing the trade-off between these parameters.
3Object-generated harmful factors
If ultra-wideband radio is deployed to minimize interference to other radios, then interference to co-existing users is reduced, but range is shortened and complexity increases
Solution Approach 1:
The system dynamically selects between narrowband and ultra-wideband radios based on real-time communication conditions and requirements. The ultra-wideband radio is deployed when minimizing interference to other radios is the priority, while the narrowband radio is used when communication range is more critical. This dynamic adaptation allows the system to optimize interference characteristics without permanently sacrificing range, and vice versa.
