Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If cables are used to connect power supply to electric linear actuator, then power supply is stable and reliable, but movement range is limited and cable management becomes cumbersome
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless power transmission system. The electric linear actuator is equipped with a wireless receiver that receives power wirelessly from a transmitter, eliminating the need for physical cable connections and enabling free movement within the wireless signal range.
Solution Approach 2:
The patent extracts and removes the cable component from the power supply system. By separating the power transmission function from the physical cable connection, the system allows the actuator to move freely without being constrained by cable length or requiring cable winding and management.
2Ease of operation
If cable length is increased to extend movement range, then movement freedom is improved, but cable becomes cumbersome and takes up space
Solution Approach 1:
The patent substitutes the mechanical cable-based power transmission system with a wireless electromagnetic field-based power transmission system. This eliminates the need for storing and managing long cables, as power is transmitted through electromagnetic waves without requiring physical connection materials.
3Adaptability or versatility
If wireless charging is implemented, then movement range is no longer limited by cables, but power conversion circuitry is required
Solution Approach 1:
The patent integrates multiple functions into the wireless power reception system. The wireless receiver not only receives power wirelessly but also includes integrated power conversion circuitry that converts the received wireless power into usable electrical power for the actuator motor, combining power reception and power conversion in a single integrated system.
