Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electromagnetic signals are transmitted over large distances to charge devices wirelessly, then wireless charging capability is improved, but energy transmission efficiency deteriorates due to 1/r2 attenuation
Solution Approach 1:
The system segments the wireless power transmission into multiple relay nodes (transmitters and receivers) positioned at intermediate locations between the power source and the target device. Each node transmits power only over short distances to the next node, avoiding the need for single long-distance transmission and thereby reducing energy loss from 1/r2 attenuation.
Solution Approach 2:
Intermediate transmitter and receiver devices act as mediators in the power transmission chain. These intermediary nodes receive power from nearby transmitters and forward it to subsequent nodes or directly to the target device, enabling efficient step-by-step power delivery without requiring direct long-range transmission.
2Power
If transmitted power is boosted to maintain signal strength over distance, then received power is improved, but energy waste and interference with other devices increases
Solution Approach 1:
By dividing the transmission path into multiple short segments with intermediate nodes, each node transmits at lower power levels sufficient only for its immediate vicinity. This segmentation eliminates the need for high-power long-distance transmission, reducing overall energy waste while maintaining adequate received power at each stage.
Solution Approach 2:
Each transmitter node is configured to provide localized power transmission optimized for its specific coverage area rather than attempting broad long-range coverage. This local quality approach ensures that power is transmitted at appropriate levels for each local context, minimizing waste and interference while meeting local power delivery requirements.
3Adaptability or versatility
If wireless power transmission is made available to all users, then accessibility is improved, but resource abuse and inefficient utilization increases
Solution Approach 1:
The system incorporates feedback mechanisms where transmitters and receivers communicate transmission parameters, power delivery status, and usage information. This feedback enables the network to monitor and manage power distribution, identify abuse patterns, and dynamically adjust transmission parameters to optimize resource utilization while maintaining broad accessibility.
Solution Approach 2:
The wireless power network dynamically adjusts transmission parameters, node activation, and power allocation based on real-time conditions and usage patterns. This dynamic behavior allows the system to accommodate multiple users and diverse applications while preventing resource abuse through adaptive control and efficient resource management.
