Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single ultrasonic transducer is used, then the device structure is simple, but the focal depth is limited to a single depth and treatment effectiveness is restricted
Solution Approach 1:
The patent divides the ultrasonic treatment function into multiple independent transducer units, each capable of operating at different focal depths. This segmentation allows the system to treat multiple depth levels simultaneously, enhancing treatment effectiveness while maintaining relative structural simplicity through modular design.
Solution Approach 2:
The patent introduces the depth dimension by configuring multiple transducers at different positions and orientations. This dimensional expansion from a single focal point to multiple focal points at different depths enables comprehensive treatment of various skin layers without proportionally increasing device complexity.
2Adaptability or versatility
If the ultrasonic generator is rotated in a tilted state, then the focal point can be positioned diagonally on the skin, but the structure becomes complicated and manufacturing cost increases
Solution Approach 1:
The patent segments the ultrasonic generation function across multiple transducers that can be independently positioned and oriented. This eliminates the need for a single complex tilted rotation mechanism, as each transducer can be individually angled to achieve diagonal focal points on the skin surface.
Solution Approach 2:
Each transducer unit is configured with specific local orientation and positioning to achieve the desired focal point distribution. This local quality approach allows diagonal focal positioning without requiring a complex overall device structure, as each component is optimized independently.
3Adaptability or versatility
If multiple protruding members are brought into contact with the top of the ultrasonic generator, then the focus can be moved along a circular path, but the structure becomes complicated and a large load is required to rotate the ultrasonic generator
Solution Approach 1:
The patent segments the circular motion function across multiple independently controllable transducers. Each transducer can be positioned at different radial distances from the rotation center, allowing focal points to move along circular paths without requiring a single heavy rotating generator, thus reducing motor load.
Solution Approach 2:
The patent introduces radial distance as an additional dimension for transducer positioning. By arranging transducers at multiple radial distances from the rotation center, the system achieves circular focal point movement through dimensional diversity rather than through a single complex rotation mechanism, reducing the required motor load.
4Ease of operation
If ultrasonic waves are delivered in a curved shape due to pivot mechanism, then the focal point can be moved, but the energy delivered to the skin decreases and focal depth changes toward the periphery resulting in uneven treatment
Solution Approach 1:
The patent segments the ultrasonic energy delivery into multiple independent transducer channels, each capable of maintaining a consistent focal depth. This segmentation allows the system to overcome the curvature problem of single-pivot mechanisms by distributing energy across multiple focal points that can be independently controlled to maintain uniform depth and energy delivery.
Solution Approach 2:
The patent changes the operational parameters by allowing each transducer to operate at its own optimized focal depth and angle. This parameter independence enables the system to maintain uniform energy delivery across the treatment area while still achieving the desired focal point movement, eliminating the depth variation problem of curved delivery paths.
