Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If liquid ultrasonic coupling gel is used, then ultrasonic transmission is effective, but it is inconvenient to clean and has high cost
Solution Approach 1:
The patent changes the physical state of the ultrasonic coupling gel from liquid to solid form. The solid gel is provided in a storage container and applied to the ultrasonic head, maintaining ultrasonic transmission effectiveness while eliminating the cleaning issues associated with liquid gel. This parameter change (from liquid to solid state) directly resolves the contradiction between effective ultrasonic transmission and cleaning convenience.
2Ease of operation
If solid-state ultrasonic coupling gel is used, then cleaning is easier, but it is difficult to fix and high in cost
Solution Approach 1:
The patent segments the solid ultrasonic coupling gel into a storage container portion and an application portion. The gel is stored in a container that can be easily attached to or removed from the ultrasonic head, simplifying the fixing process. This segmentation allows the gel to be easily replaced without complex fixing mechanisms, addressing the contradiction between cleaning ease and fixing difficulty.
Solution Approach 2:
The patent introduces a storage container as an intermediary between the solid ultrasonic coupling gel and the ultrasonic head. The container serves as a mediator that simplifies the attachment and removal process, making the solid gel easier to fix and replace while maintaining cleaning convenience.
3Ease of manufacture
If solid ultrasonic coupling gel is used, then cost is reduced, but assembly and attachment require simplification
Solution Approach 1:
The patent divides the device into segmented components: a storage container for the solid ultrasonic coupling gel and an ultrasonic head. This segmentation simplifies the overall structure and assembly process, allowing the gel container to be independently manufactured and attached to the ultrasonic head, thereby reducing manufacturing complexity while maintaining cost-effectiveness.
Solution Approach 2:
The storage container is designed to be nested with or attached to the ultrasonic head, creating a compact integrated structure. This nesting approach simplifies the overall device structure while maintaining ease of assembly and manufacturing, addressing the contradiction between assembly ease and structural simplicity.

AI summary
The present disclosure provides an ultrasonic device including an ultrasonic head connected to the body through a lead wire or wirelessly, a fixing piece and an ultrasonic coupling gel. The fixing piece includes a cover plate and a peripheral wall circumferentially connected with the cover plate. The peripheral wall is sleeved on the ultrasonic head to realize connection between the fixing piece and the ultrasonic head, and at the same time, an accommodation space is formed between the ultrasonic head and the cover plate. The ultrasonic coupling gel includes a first connecting part that is accommodated in the accommodation space and respectively attached to the ultrasonic head and the cover plate. Close connection between the ultrasonic coupling gel and the ultrasonic head is realized by arranging the first connecting part between the ultrasonic head and the cover plate, so that the force on the first connecting part is more uniform.
