Soldering Iron Head Slot Geometry for Bent Cable Conductors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soldering iron heads struggle to accommodate and position bent end conductors of cables, requiring the conductor to be straightened, which complicates the welding operation.
Innovation Solution
A soldering iron head with a trapezoidal positioning slot that gradually increases in width from one side surface to the other, allowing bent end conductors to be positioned without interference, eliminating the need for straightening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a V-shaped positioning slot is used to locate the end conductor, then the conductor can be positioned when straight, but bent conductors interfere with the slot edge and cannot be accommodated
Solution Approach 1:
The positioning slot cross-section is changed from V-shaped to trapezoidal shape, and the width of the upper bottom facing side is made to gradually increase from one side to the other. This parameter change allows the slot to accommodate both straight and bent end conductors without interference, resolving the contradiction between positioning ease and adaptability to bent conductors
Solution Approach 2:
The positioning slot is designed with an asymmetric trapezoidal cross-section where the width gradually increases from one side to the other. This asymmetric design creates additional space that accommodates bent conductors while maintaining effective positioning capability, thus improving both adaptability and ease of operation
2Manufacturing precision
If the end conductor must be straightened before welding, then positioning in the V-shaped slot is possible, but the welding operation becomes more complex
Solution Approach 1:
By changing the positioning slot cross-section from V-shaped to trapezoidal with a gradually increasing width, the slot can accommodate bent conductors directly without requiring straightening. This maintains positioning accuracy while significantly reducing the complexity of the welding operation

AI summary
A soldering iron head includes a bottom surface, a first side surface, a second side surface opposite to the first side surface, and a positioning slot formed on the bottom surface and extending between the first side surface and the second side surface. The positioning slot is adapted to accommodate and position an exposed end conductor of a cable. The cross section of the positioning slot is trapezoidal in shape, absent a lower bottom. An upper bottom facing side of the trapezoidal cross section of the positioning slot gradually increases in width from the first side surface to the second side surface.
