Solution Overview

Problem

Existing ultrasonic generators lack the ability to easily switch waveguides based on application requirements, as the waveguide is often integrated with the ultrasonic wave converging unit, limiting flexibility and optimization.

Innovation Solution

The ultrasonic generator design includes a separate waveguide joined to the ultrasonic wave converging unit through a joining section, allowing for easy adaptation to different applications without obstructing the ultrasonic wave propagation path.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the waveguide is integrated with the ultrasonic wave converging unit, then the structural complexity is reduced, but the adaptability to different applications deteriorates

Engineering Contradiction:

Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The ultrasonic generator is divided into separate functional modules: the ultrasonic wave generation source, the ultrasonic wave converging unit, and the waveguide. This segmentation allows each component to be independently optimized and selected based on specific application requirements, thereby improving adaptability without significantly increasing overall system complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The ultrasonic wave converging unit is designed as a universal component that can work with different waveguide configurations. By standardizing the interface and mounting structure, the same converging unit can be used across multiple applications with different waveguide requirements, achieving versatility without proportionally increasing device complexity.

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

2Adaptability or versatility

If the waveguide is a separate member joined to the ultrasonic wave converging unit, then the adaptability to different applications is improved, but the device complexity increases

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system is segmented into independently replaceable modules, with the waveguide being a separate member that can be joined to or removed from the ultrasonic wave converging unit. This modular approach enables easy adaptation to different applications by simply changing the waveguide component, while the joining mechanism is designed to be simple and standardized to minimize the increase in overall device complexity.

Inventive Principle:
Principle #1Segmentation

3Strength

If the joining section is disposed in the region obtained by extending the outer peripheral edge of the ultrasonic wave generation source, then the waveguide can be securely joined, but the ultrasonic wave propagation path may be obstructed

Engineering Contradiction:

Solution Approach 1:

The joining section is strategically positioned in a specific region that balances joining strength and wave propagation. The joining structure is designed to provide adequate mechanical strength while being localized in an area that does not interfere with the main ultrasonic wave propagation path, thus achieving both secure joining and minimal wave obstruction through optimized local design.
