Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional wire methods are used in slim cockpit design, then wiring flexibility is reduced, but manufacturing simplicity is maintained
Solution Approach 1:
The patent combines multiple wire functions into a single integrated printed circuit board structure. The PCB integrates power supply wires, signal wires, and ground wires into one unified component, eliminating the need for separate wire connections and reducing wiring configuration complexity while maintaining design flexibility.
Solution Approach 2:
The patent replaces the mechanical wire connection system with an electronic printed circuit board system. Instead of using physical wires that require manual routing and connection, the invention uses a PCB with pre-defined conductive traces that provide electrical connections through the circuit board layers, thereby improving adaptability while reducing overall system complexity.
2Ease of operation
If interior lightings are configured inside the knob in narrow space, then convenience is improved, but wire exposure and interference risks increase
Solution Approach 1:
The patent merges the lighting system with the knob structure by integrating the light source and its electrical connections directly into the PCB within the knob assembly. This integration eliminates exposed wires and potential interference points, maintaining reliability while providing the convenience of interior lighting.
Solution Approach 2:
The patent replaces the traditional wire-based electrical connection system with a PCB-based system for the interior lighting. The conductive traces on the PCB provide reliable electrical connections to the light source without requiring physical wire routing, thereby eliminating wire exposure and interference risks while maintaining the convenience function.
3Reliability
If laser manufacturing antenna method is used to plate lead wires, then wire integration and reliability are improved, but manufacturing complexity increases
Solution Approach 1:
The patent replaces traditional mechanical wire attachment methods with a laser-based manufacturing process. The laser manufacturing antenna method uses laser energy to plate and secure lead wires onto the PCB, providing superior connection reliability through precise, high-energy bonding that eliminates loose connections and improves electrical contact.
Solution Approach 2:
The patent changes the manufacturing process parameters by introducing laser technology with specific energy levels and precision control. The laser manufacturing antenna method uses controlled laser parameters (power, duration, focus) to create reliable wire connections, transforming the manufacturing process from mechanical to optical-energy-based while achieving improved reliability.
