Prostate Massage Device With Variable Pressure and Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing prostate massage devices require users to sit and reciprocate a chair, are inconvenient, and offer constant massage compression strength regardless of position, leading to decreased efficiency and comfort.
Innovation Solution
A prostate massage device with a base member, a support plate, a rotatable massage roller, an elastic spring, and a height adjusting mechanism, allowing variable pressure intensity and easy height adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user sits on the chair plate and allows the chair plate to reciprocate along the rail, then the rotatable body can press and massage the perineum, but the operation becomes inconvenient and complex
Solution Approach 1:
The patent extracts the massage function from a complex chair-based system and concentrates it into a simple handheld device. The massage head with roller can be manually held and moved directly on the perineum, eliminating the need for the entire chair plate, rail mechanism, and body weight dependency. This extraction of the core massage function resolves the contradiction by simplifying operation while maintaining effectiveness.
Solution Approach 2:
Instead of having the user's body weight drive the massage through a complex chair mechanism, the invention inverts the approach by making the massage head itself the active element that can be directly manipulated. The handheld design allows the user to control the massage directly without intermediary mechanical systems, thus improving ease of operation while reducing device complexity.
2Productivity
If an elastic spring is used to achieve elastic load of the rotatable body, then the massage action is provided, but the compression strength becomes constant regardless of position, decreasing massage efficiency
Solution Approach 1:
The patent replaces the static elastic spring mechanism with a dynamic motor-driven system. The motor can adjust the rotation speed and torque of the massage roller dynamically, allowing compression strength to vary according to position and user needs. This dynamic control enables the massage device to adapt to different anatomical regions and massage stages, resolving the contradiction between productivity and adaptability.
Solution Approach 2:
The invention changes the physical parameters of the massage action by using motor control to vary rotation speed, torque, and pressure. Instead of relying on the fixed elastic properties of a spring, the motor-driven system can adjust these parameters in real-time based on position and user feedback, thereby improving both massage efficiency and adaptability to different treatment requirements.
3Ease of operation
If the rotatable body is pushed downward by body weight during reciprocation, then massage pressure is applied, but the structure becomes complex and difficult to adjust
Solution Approach 1:
The patent segments the massage device into independent modular components: a handheld massage head with motor, battery, and control unit. This segmentation eliminates the need for complex integrated structures like the chair plate, rail system, and multiple frame components. Each module can be independently adjusted or replaced, improving ease of operation while reducing overall structural complexity.
Solution Approach 2:
The handheld design allows the user to self-adjust the position and pressure of the massage head directly on the perineum without requiring external adjustment mechanisms. The battery-powered motor provides autonomous operation without needing external power sources or complex mechanical linkages, enabling easy height and pressure adjustment while minimizing structural complexity.
