Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate wires are used to couple each needle to the pin on the adapter plate, then electrical connection is achieved, but the wire easily breaks during high-speed reciprocating movement
Solution Approach 1:
The patent combines multiple separate wire connections into a single flexible circuit board that electrically connects all needles to the adapter plate. This integration eliminates the complexity of managing multiple individual wires while maintaining all necessary electrical connections, directly resolving the contradiction between reliability and device complexity.
Solution Approach 2:
The patent employs a flexible circuit board instead of rigid wires to connect the needles. The flexible nature of this thin film structure allows it to withstand high-speed reciprocating movements without breaking, significantly improving reliability while keeping the internal circuit design simpler and more compact.
2Reliability
If multiple wires are provided to match the number of needles, then electrical connection is achieved, but the treatment tip volume increases and needle-density decreases
Solution Approach 1:
The patent merges multiple individual wire connections into a single integrated flexible circuit board. This consolidation dramatically reduces the overall volume required for electrical connections while maintaining reliable electrical contact with all needles, effectively resolving the contradiction between connection reliability and treatment tip compactness.
Solution Approach 2:
By using a flexible circuit board instead of multiple separate wires, the patent achieves a much more compact design. The thin film structure of the flexible circuit board allows it to occupy minimal space while providing all necessary electrical connections, thereby reducing treatment tip volume and increasing needle-density.
3Reliability
If separate wires connect each needle, then electrical connection is achieved, but aesthetics deteriorate due to increased spacing area
Solution Approach 1:
The patent integrates multiple wire connections into a single flexible circuit board, which maintains electrical connection stability while significantly improving the compactness and aesthetic appearance of the treatment tip. The unified structure eliminates the bulky appearance caused by multiple separate wires.
Solution Approach 2:
The flexible circuit board's thin film construction allows for a sleek, compact design that maintains all necessary electrical connections without the visual bulk of multiple separate wires. This improves the overall aesthetics and compactness of the treatment tip while ensuring stable electrical connections.
