Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an air gap is provided between the roadway and the secondary coil to clear debris, then safety is improved, but inductive coupling effectiveness deteriorates
Solution Approach 1:
The secondary coil is mounted on a movable suspension system that dynamically adjusts its position relative to the roadway. The coil can lower itself to minimize the air gap when conditions permit, and raise itself to clear debris when necessary, thus optimizing the balance between safety and inductive coupling effectiveness throughout the vehicle's operation.
2Loss of energy
If the secondary coil is positioned close to the roadway for effective induction, then inductive coupling effectiveness is improved, but lateral alignment becomes difficult to maintain
Solution Approach 1:
The system incorporates sensors that detect the position of the vehicle relative to the roadway centerline and provide feedback to a control system. Based on this feedback, the suspension system automatically adjusts the lateral position of the secondary coil to maintain optimal alignment with the embedded primary coil, ensuring consistent inductive coupling effectiveness even when the vehicle drifts from the centerline.
3Power
If high-frequency alternating current is used in the primary coil to increase induced current, then power output is improved, but health and safety concerns increase
Solution Approach 1:
The system dynamically adjusts the frequency and amplitude parameters of the alternating current in the primary coil based on real-time detection of vehicle presence and position. When a vehicle is detected and properly positioned, the system activates high-frequency current to maximize power transfer. When no vehicle is present or alignment is poor, the system reduces or stops current flow, thereby maintaining power output when needed while minimizing health and safety risks during other times.
