Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the ultrasonic wave generating source generates ultrasonic waves frontward along the axial direction, then the ultrasonic waves can be effectively transmitted, but the design flexibility is limited
Solution Approach 1:
The patent applies asymmetry by configuring the joining surface at a slant angle rather than perpendicular to the waveguide axis. This asymmetric arrangement allows the ultrasonic wave generating source to be positioned at an angle, enabling flexible directional control of ultrasonic waves while maintaining effective transmission through the waveguide, thus resolving the contradiction between design flexibility and transmission efficiency
2Adaptability or versatility
If the joining surface is arranged perpendicular to the waveguide axis, then the structure is simple, but the design flexibility is reduced
Solution Approach 1:
The patent changes the geometric parameter of the joining surface from a perpendicular arrangement to a slanted arrangement at a specific angle. This parameter change enables the ultrasonic wave generating source to radiate waves at optimized angles for different applications, providing design flexibility while the slant angle can be precisely controlled during manufacturing to maintain ease of fabrication
3Volume of moving object
If the ultrasonic wave generating device uses a conventional axial configuration, then the transmission path is straightforward, but the device size cannot be reduced
Solution Approach 1:
The patent transitions from a conventional one-dimensional axial configuration to a two-dimensional slanted configuration by arranging the joining surface at an angle. This dimensional change allows the ultrasonic waves to propagate through the waveguide more efficiently at an optimized angle, improving transmission efficiency while enabling more compact device positioning and potentially reducing overall device size
