Modular Ultrasonic Waveguide Joining for Flexible Generator Tuning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ultrasonic generators lack the ability to readily optimize the waveguide for different applications, as the waveguide is often integrated with the ultrasonic wave converging unit, limiting flexibility and efficiency.
Innovation Solution
The ultrasonic generator design includes a separate waveguide joined to the ultrasonic wave converging unit through a joining section, allowing for the waveguide to be easily adapted to various applications while using the ultrasonic wave generation source and converging unit in common, with features like recesses, projections, and screwing structures to enhance joining without obstructing ultrasonic wave propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the waveguide is integrated with the ultrasonic wave converging unit, then the structure is simplified and the number of parts is reduced, but the adaptability to different applications is limited
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 the waveguide to be independently selected and optimized for different applications while reusing the common components (generation source and converging unit), thereby improving adaptability without significantly increasing overall system complexity.
Solution Approach 2:
The ultrasonic wave generation source and ultrasonic wave converging unit are designed as universal components that can be used with different waveguide types. By standardizing the interface and mounting structure, the same generation source and converging unit can support multiple waveguide configurations (different lengths, materials, end shapes) to meet various application requirements.
2Adaptability or versatility
If the waveguide is made separate from the ultrasonic wave converging unit, then the adaptability to different applications is improved, but the number of parts and assembly complexity increases
Solution Approach 1:
The waveguide is joined to the ultrasonic wave converging unit through a joining section, merging these separate components into a functional assembly. This joining approach allows the components to be manufactured separately (enabling waveguide optimization for different applications) while creating a unified structure during assembly, thus balancing adaptability with ease of manufacture.
3Reliability
If the joining section is positioned in the region obtained by extending the outer peripheral edge of the ultrasonic wave generation source, then the ultrasonic wave propagation is minimized from obstruction, but the joining strength may be reduced
Solution Approach 1:
The joining section is specifically positioned in a region that is optimized for both ultrasonic wave propagation and joining strength. By carefully selecting the location where the waveguide joins the converging unit, the design ensures that the joining area does not interfere with the ultrasonic wave path while still providing sufficient structural strength through appropriate joining methods and structural features.

Implementation Method 1
The first reflective surface is a curved surface that is convex in a direction away from the ultrasonic wave generation source and reflects the ultrasonic wave generated by the ultrasonic wave generation source toward the second reflective surface
Implementation Method 2
The second reflective surface reflects the ultrasonic wave reflected by the first reflective surface toward the waveguide so that the ultrasonic wave is introduced into the waveguide
