Solution Overview
Problem
Existing high-load couplers require complex construction and manufacturing efforts due to the need for separate assemblies and external absorbers, leading to increased production costs and assembly complexity.
Innovation Solution
A high-load coupler design that integrates the absorber connection using a triplate line with a center conductor, eliminating the need for separate printed circuit boards and allowing for a simpler construction by using a single line strip for both coupling and absorber connection, which also serves as an impedance transformer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If external absorbers are used with separate printed circuit boards, then the coupler can handle high power loads, but the construction effort and manufacturing complexity increase significantly
Solution Approach 1:
The patent merges the absorber connection and coupling functions into a single integrated structure. The second line strip serves dual purposes: it provides the coupling path for the second input signal and simultaneously connects to the absorber, eliminating the need for separate printed circuit boards and reducing construction complexity while maintaining power handling capability
Solution Approach 2:
The second line strip is designed as a multi-functional element that performs both coupling and absorber connection functions. This universal component approach reduces the number of separate parts needed and simplifies the overall device structure without compromising its high power handling ability
2Power
If external absorbers are used with separate printed circuit boards, then the coupler can handle high power loads, but the manufacturing effort and assembly complexity increase
Solution Approach 1:
By combining the absorber connection and coupling functions into a single integrated line strip structure, the patent eliminates the need for separate printed circuit board assemblies. This integration significantly reduces manufacturing steps, assembly operations, and the complexity of population from two sides, making the device easier to manufacture while maintaining high power capability
3Adaptability or versatility
If a complex housing with two-sided population is used, then the coupler can accommodate separate absorber assemblies, but the construction effort increases
Solution Approach 1:
The patent eliminates the need for complex two-sided housing population by integrating the absorber connection into the line strip structure itself. This allows for a simpler housing design that does not require separate absorption chambers or complex mounting arrangements, reducing construction effort while maintaining the ability to accommodate the absorber

Function Achieved in This Case
This design simplifies the production and assembly of the high-load coupler, reduces construction effort, and enables efficient heat dissipation through a coolant line, while maintaining effective signal coupling and impedance matching.
Implementation Method 1
In order to dissipate the heat generated in the absorber when an input signal fails, the absorber is preferably arranged on a heat-conducting surface of a coolant line
Implementation Method 2
By arranging the absorber on such a coolant line, the amount of heat that occurs can be dissipated in a simple manner by a coolant
