Volute Shell Massager Segmented Nose for Pressure Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Volute shell-type massagers face issues with uneven pressure distribution and deflection due to the extended arm body, leading to imbalance and inability to maintain intended massage posture, especially when the carrier deviates from its axis.
Innovation Solution
A volute shell-type massage structure with a wand-type massage body and a volute shell nose forming a wrapping angle sector, where the volute shell nose is connected to the wand-type massage body with a specific connecting angle, allowing the volute shell body to maintain contact with the outer surface and adapt to different depths, ensuring balanced and uninterrupted massage stimulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the arm body length is extended to enable the volute shell massage body to enter the human body, then the massage coverage is improved, but the pressure distribution becomes uneven and the structure becomes unstable
Solution Approach 1:
The volute shell nose is divided into two wrapping angle sectors: S1 (continuously connected to volute shell body) and S2 (separated from volute shell body). This segmentation allows different functional zones - S1 provides structural support for stable pressure distribution, while S2 allows adaptive movement for massage coverage.
Solution Approach 2:
Different portions of the volute shell nose have different connection states to the volute shell body. The S1 sector maintains continuous connection for stability, while the S2 sector is separated to allow independent movement and adaptation, creating local quality differences that resolve the contradiction between coverage and stability.
2Length of moving object
If the arm body length is extended to reach the intended massage position, then the massage depth is improved, but the head portion becomes heavier and prone to deviation
Solution Approach 1:
The S2 wrapping angle sector is extracted from the continuous structure of the volute shell nose, creating a separated portion that can move independently. This extraction reduces the effective weight that contributes to deviation while maintaining the overall length needed for massage depth.
Solution Approach 2:
The separated S2 sector introduces dynamic capability to the structure, allowing the head portion to adapt its position and orientation in response to carrier deviation, thereby compensating for the weight issue and maintaining stable massage contact.
3Strength
If the volute shell nose is continuously connected to the volute shell body, then the structural strength is improved, but the adaptability to depth changes and deviation is reduced
Solution Approach 1:
The volute shell nose is segmented into S1 (connected) and S2 (separated) sectors. The S1 sector maintains continuous connection for structural strength, while the S2 sector is separated to provide adaptability to depth changes and carrier deviation.
Solution Approach 2:
Different sectors of the volute shell nose have different connection qualities - S1 has strong continuous connection for structural integrity, while S2 has separated connection for adaptability, creating local quality variations that simultaneously satisfy both strength and adaptability requirements.
4Area of stationary object
If the wrapping angle sector is increased to improve massage coverage, then the massage area is expanded, but the connecting angle becomes less effective in maintaining orientation
Solution Approach 1:
The wrapping angle sector is segmented into S1 and S2 with different connection states. This segmentation allows the total wrapping angle to be increased for broader massage coverage while the S1 sector maintains precise orientation through continuous connection.
Solution Approach 2:
Different angular sectors have different functional qualities - S1 maintains precise orientation control through continuous connection, while S2 allows broader angular coverage through separated connection, enabling both large massage area and precise orientation where needed.

AI summary
A volute shell-type massage structure and a volute shell-type massager are disclosed. The volute shell-type massage structure includes a wand-type massage body; a volute shell massage body having a volute shell nose and a volute shell body; the volute shell nose is connected to the volute shell body to form a wrapping angle sector S, the volute shell nose in a wrapping angle sector S1 is continuously connected with the volute shell body, and the volute shell nose in a wrapping angle sector S2 is separated from the volute shell body; and the volute shell nose is connected to the wand-type massage body to form a connecting angle b1. When the volute shell body receives acting force from an outer surface of a hole-shaped part to be massaged, the volute shell nose can exert retraction force on the volute shell body, such that strong uninterrupted massage stimulation effects are achieved.
