Flexible-Shell Massage Device for Swinging Under Body Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massage devices struggle to provide an effective massage experience due to resistance from the massaged body parts, limiting their ability to generate sufficient force and resulting in suboptimal massage outcomes.
Innovation Solution
A massage device with a shell containing a moving space that allows a massage member to swing laterally, providing sufficient space for the massage member to extend beyond the shell and apply strong force despite resistance, combined with a driving member to facilitate this motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the massage head performs linear reciprocating motion, then the device structure is simple, but the massage effect is poor due to body resistance
Solution Approach 1:
The massage head is changed from linear reciprocating motion to swinging motion, allowing it to dynamically adapt to body resistance. The swinging motion enables the massage head to penetrate deeper into muscle tissue and deliver more effective mechanical stimulation while maintaining structural simplicity.
Solution Approach 2:
The motion parameters of the massage head are changed from linear reciprocating to swinging motion with variable amplitude and frequency. This parameter change allows the massage device to overcome body resistance more effectively while maintaining a simple overall structure.
2Volume of moving object
If the massage head is constrained within the shell, then the device structure is compact, but the massage force is insufficient under resistance
Solution Approach 1:
The massage head is allowed to move in a swinging arc trajectory rather than being constrained to linear motion within the shell. This dimensional change in motion path enables the massage head to generate greater penetrating force against body resistance while the shell maintains its compact protective structure.
Solution Approach 2:
The shell is designed with a through-hole that segments the internal space, allowing the massage head to extend beyond the shell boundary during swinging motion. This segmentation enables the massage head to achieve sufficient stroke length and force while the shell remains compact and protective.

AI summary
A massage device includes a flexible outer shell configured with a front portion, a rear portion, and a middle portion between the front and rear portions; an annular wall concaved from a top side towards a bottom side of the middle portion and encircling a moving space that communicates with an outside environment, an interior chamber of the front/rear portion being not communicated with the moving space; and a massage member configured with a flexible cover protruding from the annular wall towards the moving space. During use, the front portion and middle portion of the flexible outer shell are inserted into a cavity of a human body, and the massage member is driven to at least reciprocate to a first position inside the moving space and a second position above the moving space to massage a cavity wall of the human body around the flexible outer shell.
