Existing ultrasound devices face challenges with inconvenient and high-cost ultrasonic coupling gels, particularly due to their liquid state and the difficulty in fixing and using solid-state gels effectively.
Innovation Solution
An ultrasonic device design featuring a solid-state ultrasonic coupling gel with a connecting part accommodated between the ultrasonic head and a cover plate, forming an accommodation space to reduce stress concentration and facilitate easy assembly, along with a peripheral wall that is magnetically or elastically connected to the ultrasonic head, and a through hole for the protruding part to contact the skin, enhancing assembly efficiency and reducing friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If liquid ultrasonic coupling gel is used, then the ultrasound can act on the treatment site, but it is inconvenient to clean
Solution Approach 1:
The patent changes the physical state of the ultrasonic coupling gel from liquid to solid gel state. The solid gel maintains the necessary acoustic coupling properties while eliminating the messiness and cleaning difficulties associated with liquid gels. This parameter change directly resolves the contradiction between maintaining ultrasound transmission and improving ease of cleaning.
2Ease of operation
If solid-state ultrasonic coupling gel is used, then cleaning is easier, but it is inconvenient to fix and high in cost
Solution Approach 1:
The solid gel is divided into two functional parts: a connecting part with adhesive properties for attachment to the ultrasonic head, and a protruding part that extends through the cover plate to contact the skin. This segmentation allows the gel to be easily fixed to the device while maintaining its solid-state cleaning advantages, resolving the contradiction between ease of cleaning and ease of fixation.
Solution Approach 2:
The connecting part of the solid gel acts as an intermediary between the ultrasonic head and the skin, providing both adhesive attachment to the device and acoustic coupling to the skin. This intermediary structure simplifies the overall system by integrating both fixation and coupling functions into a single component, reducing complexity and cost.
3Device complexity
If the ultrasonic coupling gel is directly attached to the ultrasonic head, then the assembly is simple, but the gel may bend and break during assembly
Solution Approach 1:
The connecting part of the solid gel is designed with adhesive properties and sufficient thickness to cushion and distribute mechanical stresses during the assembly process. This beforehand cushioning prevents the gel from bending and breaking when attached to the ultrasonic head, resolving the contradiction between assembly simplicity and gel reliability.
4Stability of the object's composition
If the solid gel is fully enclosed, then the assembly is stable, but the gel cannot contact the skin effectively
Solution Approach 1:
The solid gel is segmented into a connecting part for stable attachment within the accommodation space and a protruding part that extends through the cover plate to contact the skin. This segmentation simultaneously achieves stable positioning and effective skin contact, resolving the contradiction between stability and operational effectiveness.

AI summary
The present invention discloses an ultrasonic device including an ultrasonic head protruding from a body, 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 the 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 connecting part that is accommodated in the accommodation space and respectively attached to the ultrasonic head and the cover plate. The close connection between the ultrasonic coupling gel and the ultrasonic head is realized by arranging the connecting part between the ultrasonic head and the cover plate, so that the force on the connecting part is more uniform.
