Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional welding process is used to connect wires to circuit boards, then the connection is achieved, but the process is time-consuming and requires大量 manual operation
Solution Approach 1:
The patent replaces the traditional welding process with a mechanical insertion system. The wire conductive pad includes an insertion hole through which wires are mechanically inserted and fixed, eliminating the need for welding operations. This substitution dramatically reduces wiring time and manual operation requirements while maintaining connection reliability.
2Reliability
If traditional welding is used, then wires are connected to circuit boards, but solder joints are micro in size and large in quantity, making them prone to short circuits and wire detachment
Solution Approach 1:
The wire conductive pad is divided into distinct functional segments: a body portion for mounting on the circuit board, an insertion hole for wire passage, and a bending portion for mechanical locking. This segmentation allows each part to perform its specific function optimally, ensuring reliable wire fixation without requiring multiple micro solder joints.
Solution Approach 2:
The wire conductive pad acts as an intermediary component between the wire and the circuit board. Instead of directly welding the wire to the board, the pad serves as a mediator that mechanically secures the wire through its bending portion while providing an electrical connection point, thereby simplifying the connection system and improving reliability.
3Reliability
If more solder joints are used to ensure connection reliability, then wiring safety improves, but the complexity and time required for welding increases
Solution Approach 1:
The wire conductive pad is designed to be self-fixing through its bending portion. When a wire is inserted into the insertion hole, the bending portion automatically bends to mechanically lock the wire in place. This self-service mechanism eliminates the need for complex welding operations and multiple solder joints, simplifying the manufacturing process while ensuring connection stability.

Implementation Method 1
the elastic locking piece is formed on the peripheral wall and inserted into the insertion space in an inclined manner, so as to press the wire against the peripheral wall when the wire is inserted in the insertion space
Implementation Method 2
a step of heating includes heating the circuit boards, so that the solder paste is melted to fix the wire conductive pads to the contact points

AI summary
A circuit board with wire conductive pads is provided for insertion of wires, and includes: a circuit board and a wire conductive pad. The wire conductive pad includes a main body in the form of a hollow column and an elastic locking piece extending from the main body. The main body includes a peripheral wall defining an insertion space. The elastic locking piece is inserted from the peripheral wall into the insertion space in an inclined manner to press towards the peripheral wall. Wires are inserted into the insertion space and clamped against the peripheral wall by the elastic piece, so that the wires can be prevented from falling off in a reverse direction, and thus can be connected to the circuit board in a more quick and stable manner.
