Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If direct connection to BGA is used for cable termination, then manufacturing precision is improved, but productivity deteriorates due to precision slowing down the manufacturing process
Solution Approach 1:
The patent introduces a holder assembly as an intermediary component between the BGA and the cable. The holder assembly includes a holder body with a first end that couples to the BGA and a second end that receives the cable, eliminating the need for direct precision connection while maintaining signal integrity and structural stability.
2Stability of the object's composition
If direct connection to BGA is used for cable termination, then connection stability is improved, but device complexity increases due to larger termination region and outer diameter
Solution Approach 1:
The patent segments the cable termination system into distinct functional components: the holder assembly (with holder body and holder cap), the BGA, and the cable. This segmentation allows each component to be optimized independently, reducing the overall termination region size and outer diameter while maintaining connection stability through the holder's structured design.
3Reliability
If direct connection to BGA is used for cable termination, then electrical conductivity is improved, but ease of manufacture deteriorates due to assembly quality problems
Solution Approach 1:
The holder assembly serves as a mediator that simplifies the manufacturing process. The holder body can be coupled to the BGA using standard mounting techniques, and the holder cap provides a simplified interface for cable attachment, reducing assembly complexity and improving ease of manufacture while maintaining electrical connection reliability through the structured holder design.

AI summary
A shield for a cable attachment system for attaching a cable to a component having a ball grid array (BGA). The shield may comprise an outer conductive surface, a first end configured to be coupled to a surface of the component, a second end that receives the cable, and an inner non-conductive material received within the shield adjacent the first end and encasing the connection of the cable to the BGA of the component. The cable may be configured to be coupled to the BGA of the component.
