Solution Overview

Problem

The split-ring resonator in existing technologies is directly formed on a board and connected to a ground pattern, making it impossible to be used as a single component or flexibly combined with other components according to design requirements.

Innovation Solution

A split-ring resonator with a ground terminal separated from the ground pattern, a board with a terminal configured to connect to the ground terminal, and a connector that allows the split-ring resonator to be used independently and combined with other components, enabling its distribution and flexible integration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the split-ring resonator is formed directly on a board and connected to a ground pattern, then the structure is simple and easy to manufacture, but the resonator cannot be distributed as a single component or flexibly combined with other components

Engineering Contradiction:
Improveease of manufactureVSAvoidadaptability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The ground terminal is separated from the ground pattern, dividing the resonator structure into independent components. This segmentation allows the resonator to be manufactured separately and then assembled with the board, enabling both ease of manufacture and flexibility in combination with other components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The ground terminal is extracted from the integrated structure and made separable. This extraction enables the resonator to be produced as a standalone component while maintaining the ability to connect to the ground pattern through the terminal, thus achieving versatility without compromising manufacturing simplicity.

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If the ground terminal is separated from the ground pattern, then the resonator can be used as a standalone component and flexibly combined, but the structure becomes more complex

Engineering Contradiction:
ImproveadaptabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The ground terminal is designed to serve multiple functions: it acts as both the grounding element and the connection interface for assembling the resonator with the board. This multi-functionality reduces the need for additional components, thereby limiting the increase in structural complexity while achieving high adaptability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Device complexity

If the split-ring resonator is formed directly on a board, then the structure is integrated and simple, but the resonator cannot be distributed or flexibly combined according to design requirements

Engineering Contradiction:
Improvestructure simplicityVSAvoiddesign flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The ground terminal is prepared in advance as a separate component with predefined connection interfaces. This preliminary preparation allows the resonator to be manufactured independently and then flexibly assembled with different board configurations, achieving design flexibility without significantly increasing overall structural complexity.

Inventive Principle:
Principle #10Preliminary action
