Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cable cores with small cross-sectional areas are positioned and attached to correspondingly small contacting surfaces, then positioning accuracy must be high, but the difficulty of handling and positioning increases
Solution Approach 1:
The patent introduces a soldering aid as an intermediary tool between the cable core and the contacting surface. This soldering aid includes a body with a receptacle that receives the cable core, and a contact part that contacts the contacting surface. The intermediary device facilitates precise positioning and attachment of small cable cores by providing a handling interface that is much larger and easier to manipulate than the cable core itself.
Solution Approach 2:
The attachment system is segmented into distinct functional components: a body made of electrically insulating material, a contact part made of electrically conductive material, and a receptacle for the cable core. This segmentation allows each component to be optimized for its specific function while collectively solving the positioning accuracy and handling difficulty contradiction.
2Manufacturing precision
If multiple cable cores are attached to respective contacting surfaces at a defined distance from one another, then positioning precision is improved, but the device complexity increases
Solution Approach 1:
The soldering aid is designed as a universal device that can accommodate multiple cable cores simultaneously. The body contains multiple receptacles, and the contact part has multiple contact surfaces, allowing the same device structure to handle multiple attachment operations with defined spacing without requiring separate specialized tools for each cable core.
Solution Approach 2:
Multiple attachment functions are merged into a single integrated device. The body combines multiple receptacles for different cable cores, and the contact part integrates multiple contact surfaces that correspond to multiple contacting surfaces on the conductor area, enabling simultaneous positioning of multiple cable cores at defined distances.

AI summary
A soldering aid for electrically conductively connecting a cable core of a cable to a conductor area includes a body made of an electrically insulating material and an electrically conductive contact part received in the body. The contact part has a contact surface configured to electrically conductively contact the conductor area. The body is formed with a receptacle having a slot open toward one side configured to receive the cable core of the cable, and is formed with a through-bore configured to surround a sheathed portion of the cable. The contact part closes an opening at a bottom of the slot and conductively contacts the cable core.
