Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-directional high-frequency power dividers lack the ability to adjust power distribution simply without affecting the main line, limiting their versatility and adaptability.
Innovation Solution
The second inner conductor is designed to be adjustable relative to the primary inner conductor and outer conductor, allowing for variable power distribution through a radial adjustment mechanism, enabling a broadband and infinitely variable power split across a range of frequencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed non-directional power divider structure is used, then the device is simple and reliable, but the power distribution cannot be adjusted
Solution Approach 1:
The patent applies the dynamics principle by making the second inner conductor adjustable relative to the outer conductor through a radial adjustment mechanism. This allows the power distribution ratio to be dynamically changed by varying the distance between the second inner conductor and the outer conductor, transforming a static structure into a dynamic one that can adapt to different power division requirements while maintaining structural simplicity
Solution Approach 2:
The patent implements parameter changes by varying the physical distance (spacing) between the second inner conductor and the outer conductor. This geometric parameter change directly affects the characteristic impedance and power distribution ratio, enabling continuous adjustment of power split from 6 dB to 20 dB without changing the fundamental structure or adding complex control systems
2Adaptability or versatility
If the distance between conductors is changed to adjust power distribution, then power split is variable, but the characteristic impedance of the main line may be affected
Solution Approach 1:
The patent applies local quality by making only the second inner conductor adjustable while keeping the first inner conductor and outer conductor fixed in their original positions. This localized adjustment ensures that the main transmission line's characteristic impedance remains unchanged, maintaining proper impedance matching and signal integrity while still achieving variable power distribution through the adjustable second conductor's position

AI summary
An improved nondirectional radiofrequency power divider is characterized by the following features: - having an outer conductor (1) and/or outer conductor housing (1'), with a first inner conductor (11), wherein the first inner conductor (11) runs in the outer conductor (1) or in the outer conductor housing (1'), - with a second inner conductor (13), wherein the second inner conductor (13) runs in the space (15) which is formed between the first inner conductor (11) and the outer conductor (1) or the outer conductor housing (1'), - the second inner conductor (13) is electrically connected to a branch line running away therefrom or is provided therewith, the second inner conductor (13) is relatively adjustable and/or positionable in terms of the distance of said second inner conductor from the first inner conductor (11) and/or in terms of the distance of said inner conductor from the outer conductor (1) or from the outer conductor housing (1') so as to effect a variable power distribution.
