Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If wireless transmission is used to send electrical measurement data from measurement devices to control systems, then data transmission speed is improved, but signal reliability deteriorates due to obstacles and interference
Solution Approach 1:
The patent introduces wireless radio repeaters as intermediary devices that receive signals from electrical measurement devices and re-transmit them to control systems. These repeaters are strategically positioned to overcome obstacles and interference, ensuring reliable signal transmission while maintaining fast data transmission speeds throughout the power distribution system.
Solution Approach 2:
The patent divides the wireless communication path into multiple segments by deploying repeaters at intermediate locations between measurement devices and control systems. This segmentation allows each transmission hop to be optimized independently, improving overall reliability while maintaining high data transmission speeds across the entire system.
2Reliability
If repeaters are deployed to overcome obstacles and interference, then signal reliability is improved, but system complexity increases
Solution Approach 1:
The patent implements repeaters that autonomously harvest electrical energy from nearby power lines to power their operation. This self-service capability eliminates the need for external power connections, simplifying installation and reducing system complexity while maintaining high transmission reliability through strategic repeater deployment.
Solution Approach 2:
The patent designs repeaters that perform multiple functions: receiving signals, amplifying/re-transmitting signals, harvesting electrical energy from power lines, and potentially routing signals to different destinations. This multi-functionality reduces the number of separate components needed, thereby reducing overall system complexity while ensuring reliable communication.
3Area of stationary object
If repeaters are used to extend transmission range around obstacles, then coverage area is improved, but energy consumption increases
Solution Approach 1:
The patent implements repeaters that autonomously harvest electrical energy from nearby power lines to power their operation. This self-service capability eliminates the need for external power connections, simplifying installation and reducing system complexity while maintaining high transmission reliability through strategic repeater deployment.
Solution Approach 2:
The patent employs repeaters that can dynamically adjust their operational parameters, such as transmission power and signal amplification levels, based on environmental conditions and signal quality requirements. This allows the system to extend coverage area when needed while minimizing energy consumption during normal operation.
