Prostate Massage Roller with Automated Reciprocation and Variable Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional prostate massage devices require users to sit and manually move a chair board forward and backward, leading to constant massage pressure and reduced touch sense due to a fixed elastic load, making them inconvenient and less efficient.
Innovation Solution
A prostate massage device with a base body, support, cylindrical guide member, massage roller moving rod, drive motor, and height adjustment member, allowing variable pressing strength through the reciprocating motion of the massage roller and adjustable height, enhancing touch quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user manually moves the chair board forward and backward, then the massage device can be operated, but the operation convenience deteriorates and massage efficiency is reduced
Solution Approach 1:
The patent replaces the manual mechanical operation of moving the chair board with an automated driving mechanism. The driving wheel rotates to move the chair board automatically, eliminating the need for manual back-and-forth movement while maintaining continuous massage action, thus improving both operation convenience and massage efficiency.
Solution Approach 2:
The massage device performs self-service by automatically moving the chair board through the driving mechanism. The system serves itself by generating the motion required for massage without external manual intervention, allowing continuous operation while the user simply needs to position themselves correctly.
2Device complexity
If the elastic load is applied only by the elastic spring, then the structure is simple, but the massage pressing strength becomes constant and touch sense deteriorates
Solution Approach 1:
The patent introduces dynamics to the massage system by allowing the massage roller to move up and down in addition to the forward and backward motion. This creates variable pressing strength during the massage process, enhancing touch sense while maintaining reasonable structural simplicity through the addition of a guide groove and elastic member.
Solution Approach 2:
The patent combines multiple functions into the massage roller assembly: it performs both the forward-backward movement (through the driving mechanism) and the up-down pressing motion (through the guide groove and elastic member). This merging of motions creates variable pressing strength without requiring completely separate mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides a massage with varying pressing strength and improved touch quality by allowing the massage roller to move in a streamlined manner, adapting to different positions and user comfort.
Implementation Method 1
An elastic spring 24 is embedded in the fixed shaft 22 connected to the floor surface fixed plate 23 to form a structure that is pressed by a lower end portion of the U-shaped support member 21, and an upper end portion 22a of the fixed shaft is positioned in a cylindrical shape inside the accommodation groove 21a formed in the central portion of the U-shaped support member 21 to operate a structure in which, when the user sits on the chair board 30 and moves forward and backward while pressing the protrusion of the rotating body 10, the rotating body 10 is pushed about 2 to 10 mm downward and then returns to its original position by elasticity.
