Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the conventional electrical connector uses enhancing elements and buckling plates that need double processing before assembly, then the connector can be assembled, but the assembly procedure becomes more complicated
Solution Approach 1:
The patent combines the enhancing element and buckling plate into a single integrated positioning set consisting of a straight plate and bent plate. This merging eliminates the need for separate processing and assembly steps for these components, simplifying the overall assembly procedure while maintaining the structural reinforcement and positioning functions.
Solution Approach 2:
The positioning set serves multiple functions simultaneously: the straight plate provides welding support and structural reinforcement, while the bent plate provides positioning and restriction of the side arm. This multi-functionality eliminates the need for separate enhancing elements and buckling plates, reducing assembly complexity.
2Ease of manufacture
If the isolative housing is formed as a stripe and made of plastic, then the housing can be manufactured, but deformation can easily occur due to high temperature during manufacturing or transportation
Solution Approach 1:
The patent introduces positioning sets at specific locations (both ends of the isolative housing) to provide localized reinforcement and temperature resistance. These metal positioning sets are welded to the circuit board and engage with the side arms, preventing deformation at critical points while allowing the rest of the plastic housing to maintain its manufacturing advantages.
Solution Approach 2:
The connector assembly combines plastic (isolative housing) with metal (positioning sets with straight plates and bent plates). This composite structure leverages the manufacturing ease and insulation properties of plastic while utilizing the thermal stability and strength of metal to prevent deformation during high-temperature processes and transportation.
3Ease of manufacture
If the isolative housing experiences height differences at the two ends due to deformation, then the housing can be manufactured, but invalid soldering occurs when joining with the base plate
Solution Approach 1:
The positioning sets are strategically placed at both ends of the isolative housing to provide localized support and maintain precise positioning. The straight plates are welded to the circuit board and the bent plates restrict the side arms, ensuring that the housing maintains correct height and alignment at critical soldering locations, preventing invalid soldering connections.
Solution Approach 2:
The positioning sets are welded to the circuit board before the isolative housing is assembled and soldered. This preliminary action establishes a stable, precisely positioned foundation that prevents height differences and ensures proper alignment, thereby guaranteeing valid soldering connections when the housing is subsequently joined to the base plate.
4Measurement precision
If the positioning set restricts the side arm and enables fine adjustment, then the housing can be precisely positioned, but the assembly structure becomes more complex
Solution Approach 1:
The positioning function and restriction function are merged into a single positioning set consisting of a straight plate and bent plate. The straight plate provides the welding interface for positioning, while the bent plate simultaneously restricts the side arm movement. This integration achieves precise positioning without requiring separate complex positioning and restriction mechanisms.

AI summary
The present invention provides a positioning structure of the electrical connector comprising a housing with a slot and a plurality of terminals, at least two side arms positioned on the two side of the housing, every side arm is comprising an extension plate which assembled to the housing, a movable arm and a fixed arm, and the fixed arm has an inserting plate extending downwardly, and at least two positioning sets respectively receiving the side arms. Every positioning set comprises a straight plate and the bent plates respectively positioned on the two sides of the straight plate, a receiving chamber is formed between the bent plates for receiving the inserting plate. Thus by having the bottom portion of the straight plate of the positioning set and every bent plate welded to the circuit board in order to increase the welding area, and to restrict the side arm by every positioning set, thus not only the housing is precisely positioned and also the fine adjustment during the assembling can be implemented; therefore, the present invention provides the convenience for assembling, the stability for welding and accordingly to increase the yield.
