Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the DCF scheme is adopted to ensure reliable wireless communication, then communication reliability is improved, but wireless communication efficiency deteriorates because only one terminal can execute communication at a time
Solution Approach 1:
The invention changes the transmission power parameter dynamically. The transmission power determination unit sets transmission power based on signal strength measurements from access points, allowing terminals to adjust their transmission power to enable parallel communications while maintaining reliability through controlled interference levels
Solution Approach 2:
The invention introduces dynamic transmission power adjustment where terminals continuously measure signal strengths and adapt their transmission power accordingly. This dynamic approach allows the system to transition from static DCF sequential access to dynamic parallel access while maintaining communication reliability
2Area of stationary object
If transmission power is increased to extend communication range, then communication coverage is improved, but interference with other communications increases
Solution Approach 1:
The invention dynamically adjusts transmission power based on real-time signal strength measurements. By changing the transmission power parameter according to measured conditions, the system can extend coverage when needed while limiting interference to acceptable levels, resolving the contradiction between coverage area and interference
Solution Approach 2:
The invention implements a feedback mechanism where terminals measure signal strengths from access points and use this information to adjust their transmission power. This feedback loop ensures that transmission power is optimized for coverage while maintaining interference below thresholds that would disrupt other communications
3Productivity
If multiple terminals transmit simultaneously to increase communication throughput, then communication efficiency is improved, but signal collision probability increases
Solution Approach 1:
The invention changes transmission power parameters dynamically to enable controlled simultaneous transmissions. By adjusting power levels based on measured signal strengths, the system allows multiple terminals to transmit in parallel while maintaining signal quality and avoiding collisions through power-based spatial separation
Solution Approach 2:
The invention effectively segments the wireless medium by using transmission power levels to create separate communication zones. Terminals transmitting at different power levels operate in effectively separated spatial domains, allowing parallel communications without collisions while maintaining high throughput
