Solution Overview
Problem
Existing electrical connectors with holddowns attached to circuit boards face issues of complexity in manufacturing and increased cost due to mechanisms for adjusting the center of gravity, leading to tilting during soldering and requiring additional components and larger sizes.
Innovation Solution
An electrical connector design featuring a holddown formed from a single metal sheet, which serves both as a fixing member and a center of gravity adjuster, eliminating the need for additional components and complex mechanisms, thereby simplifying the manufacturing process and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a mechanism for moving the connector body is provided to adjust the center of gravity, then the center of gravity can be adjusted to prevent tilting, but the entire structure of the connector becomes complicated and the manufacturing process becomes complicated
Solution Approach 1:
The patent combines the connector body and the balance weight into a single integrated component. The balance weight is formed as an integral part of the connector body through a single molding process, eliminating the need for separate adjustment mechanisms while maintaining the ability to adjust the center of gravity by varying the weight distribution within the integrated structure.
Solution Approach 2:
The connector body serves multiple functions: it provides the structural housing for the connector and simultaneously acts as the balance weight structure. By incorporating weight adjustment capability directly into the connector body design, the structure achieves both mechanical support and center of gravity adjustment functions without requiring additional components.
2Stability of the object's composition
If balance weights are placed on the housing to adjust the center of gravity, then the center of gravity can be adjusted closer to the center, but additional components are required and the connector becomes larger
Solution Approach 1:
The balance weight function is merged into the connector body itself. The connector body is designed with internal cavities or varying wall thicknesses that allow adjustment of the center of gravity without adding external components. This integration eliminates the need for separate balance weights and reduces the overall volume of the connector assembly.
3Stability of the object's composition
If the connector body is made movable to adjust the center of gravity, then the center of gravity can be adjusted, but the manufacturing process becomes complicated
Solution Approach 1:
The patent adjusts the center of gravity by changing the physical parameters of the connector body itself, such as the distribution of material, wall thickness, or internal cavity positioning. These parameters can be varied during the molding process without requiring complex assembly steps or movable components, thereby maintaining manufacturing simplicity while achieving center of gravity adjustment.
