Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing substrate-mounted connectors experience disruptions in electrical connection due to displacement of tab terminals, leading to detachment of solder and instability in the connection between tab terminals and contact pieces.
Innovation Solution
A connector design featuring a frame-shaped body with connection parts, fixed parts, floating parts, and a restraining part, allowing for elastic deformation and movement to maintain stable connection even with displacement of the mating conductor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connector uses legs suspended from four corners with contact pieces to guide tab terminal displacement, then the tab terminal can be guided when slightly displaced, but when considerably displaced the solder detaches and electrical connection is disrupted
Solution Approach 1:
The connector body is designed to be movable relative to the circuit substrate, allowing the entire connector to shift position when the tab terminal is considerably displaced. This dynamic structure prevents excessive stress on the solder joints while maintaining electrical contact through the flexible connection parts.
Solution Approach 2:
The connector is divided into distinct functional parts: a movable connector body, separate connection parts for electrical contact, and floating parts that provide flexible support. This segmentation allows each component to handle displacement differently, with the body moving to accommodate large displacements while connection parts maintain stable electrical contact.
2Strength
If the legs receive load through contact pieces when tab terminal is considerably displaced, then the tab terminal connection is maintained, but the solder connecting the legs to the circuit substrate detaches
Solution Approach 1:
The floating parts act as intermediaries between the connector body and the circuit substrate, providing a flexible connection that absorbs displacement forces. This mediator structure prevents direct transmission of excessive load to the solder joints while maintaining the electrical connection path.
Solution Approach 2:
The connector utilizes elastic deformation of its components to change physical parameters dynamically. When displacement occurs, the floating parts and connection parts deform elastically to accommodate the movement, maintaining connection force without transmitting damaging loads to the solder joints.
3Stability of the object's composition
If the connector body is fixed rigidly to the circuit substrate, then structural stability is maintained, but displacement of the mating conductor causes connection instability
Solution Approach 1:
The connector body is designed with controlled mobility through floating parts rather than rigid fixation. This dynamic design allows the connector to adapt its position in response to mating conductor displacement while maintaining overall structural integrity and stable electrical connection.
Solution Approach 2:
The floating parts function as flexible connecting elements between the connector body and the circuit substrate. These flexible components allow controlled movement and elastic deformation to accommodate displacement while maintaining structural coherence and electrical connectivity.

Function Achieved in This Case
The connector effectively maintains an electrically stable connection by allowing the frame body to move and the floating parts to deform, preventing buckling and ensuring consistent contact with the mating conductor.
