Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple components (die-casting part, dielectric layer, feed core, plastic shell) are used in the cable connection device, then the device can achieve functional requirements, but the device complexity increases and cost increases
Solution Approach 1:
The patent integrates multiple functional components into a single integrated structure. The feeder box combines the functions of the die-casting part, dielectric layer, and support structure into one unified component, eliminating the need for separate assembly of multiple parts while maintaining all necessary functions for cable connection and signal transmission.
Solution Approach 2:
The feeder box serves multiple functions simultaneously: it provides structural support, acts as a dielectric barrier, houses the circuit board, and facilitates cable routing through integrated through-holes. This multi-functionality reduces the need for separate specialized components.
2Reliability
If multiple components are used in the cable connection device, then the device can achieve functional requirements, but the manufacturing cost increases
Solution Approach 1:
By merging multiple components into a single integrated feeder box, the patent reduces the number of parts that need to be manufactured, stored, and assembled. This integration simplifies the supply chain and manufacturing process while maintaining all necessary functional performance.
3Reliability
If multiple components are used in the cable connection device, then the device can achieve functional requirements, but the assembly difficulty increases
Solution Approach 1:
The integration of multiple functions into a single feeder box eliminates the need for complex multi-step assembly processes. The unified structure with pre-integrated through-holes and mounting features allows for straightforward installation and cable routing.
4Volume of moving object
If the feed network is miniaturized and integrated, then the device size is reduced, but the difficulty of achieving optimal PIM performance and parameter performance across multiple frequency bands increases
Solution Approach 1:
The circuit board is strategically positioned within the feeder box cavity, and the through-holes are precisely located on the side walls to optimize signal transmission paths. This careful arrangement of components in specific locations maintains optimal electrical performance across multiple frequency bands despite the compact size.
Solution Approach 2:
The patent utilizes the three-dimensional space within the feeder box effectively by positioning the circuit board vertically within the cavity and routing cables through side wall through-holes. This spatial arrangement optimizes signal paths and electrical performance within the limited volume.

AI summary
A cable connection device is configured for connecting a pair of cables in a feed network and includes a feeder box having a cavity and a circuit board located in the cavity. The feeder box includes a bottom wall and at least one side wall. The circuit board has an upper surface and a lower surface opposite to the upper surface. The lower surface is fixedly connected to the bottom wall. The side wall extends from an edge of the bottom wall toward the upper surface and further extends beyond the upper surface. The side wall defines a pair of through holes. The pair of cables pass through the pair of through holes in a one-to-one correspondence manner. The pair of cables are electrically connected to the upper surface of the circuit board.
