Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the waveguide and ultrasonic wave condensation part are formed as separate members and joined to each other, then adaptability is improved, but ultrasonic wave output deteriorates due to loss at the joining interface
Solution Approach 1:
The waveguide and ultrasonic wave condensation part are formed as a single integrated component from the same material, eliminating the joining interface that causes ultrasonic wave loss. This merging approach maintains adaptability while reducing energy loss at the interface between separate members.
2Loss of energy
If the waveguide and ultrasonic wave condensation part are integrated from the same material, then ultrasonic wave output is improved by reducing loss, but adaptability deteriorates as the waveguide cannot be changed independently
Solution Approach 1:
The integrated waveguide-condensation part assembly is segmented from the ultrasonic wave generation source, allowing the waveguide to be replaced as a complete unit while maintaining the low-loss integrated structure. This enables adaptability at the module level without sacrificing the benefits of integration.
3Loss of energy
If a recessed portion is formed between the waveguide and condensation part, then ultrasonic wave output is improved by reducing interference, but device complexity increases
Solution Approach 1:
The recessed portion is formed as an integral feature of the unified waveguide-condensation part structure rather than as a separate component. This merging approach reduces device complexity while maintaining the interference-reducing benefits of the recessed geometry.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The configuration enhances ultrasonic wave output by reducing interference and loss, facilitating optimal waveguide selection and improving overall performance.
Implementation Method 1
The first reflection surface reflects the ultrasonic wave, which has been generated from the ultrasonic wave generation source, toward the second reflection surface
Implementation Method 2
The second reflection surface reflects the ultrasonic wave, which has been reflected by the first reflection surface, toward the waveguide so as to introduce the ultrasonic wave into the waveguide
Implementation Method 3
the recessed portion may be filled with a filler, and an acoustic impedance of the filler may differ from each of an acoustic impedance of the ultrasonic wave condensation part and an acoustic impedance of the waveguide. Therefore, adverse influence on an ultrasonic wave that propagates to the waveguide can be effectively suppressed.
Data Source
AI summary
An ultrasonic wave generation device including: an ultrasonic wave generation source; an ultrasonic wave condensation part; and a waveguide. The ultrasonic wave condensation part has a first reflection surface opposed to the ultrasonic wave generation source and a second reflection surface opposed to the first reflection surface. The first reflection surface reflects the ultrasonic wave, generated from the ultrasonic wave generation source, toward the second reflection surface. The second reflection surface reflects the ultrasonic wave, which has been reflected by the first reflection surface, toward the waveguide so as to introduce the ultrasonic wave into the waveguide. The waveguide protrudes from the first reflection surface to a side opposite the second reflection surface. A recessed portion is formed from the first reflection surface to the second reflection surface side along an outer circumferential surface of the waveguide.
