Solution Overview

Problem

Existing adult products rely on simple vibration or static pressing, leading to single massage effects and uneven local stimulation, failing to provide continuous and dynamic local massage for deep muscle relaxation.

Innovation Solution

A spiral peristaltic adult product design featuring a driving assembly with a telescopic rod, screw rod, and vibration motor, enabling linear reciprocation, rotation, and vibration to stimulate the PC muscle group and vaginal sphincter with continuous and multi-directional massage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If simple vibration or static pressing is used for massage, then the device structure is simple, but the massage effect is single and cannot provide continuous and dynamic local massage

Engineering Contradiction:
Improvedevice structureVSAvoidmassage effect
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent applies the dynamics principle by transforming the static pressing structure into a dynamic peristaltic motion system. The screw rod rotates to drive multiple balls to move along its spiral groove, creating continuous dynamic massage motion that adapts to different muscle groups and provides varied stimulation patterns, resolving the contradiction between structural simplicity and massage versatility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent segments the massage function into multiple independent balls distributed along the screw rod. Each ball can independently contact and massage different areas, allowing the system to cover larger areas and provide multi-point simultaneous stimulation, thereby enhancing massage adaptability without significantly increasing overall structural complexity.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If fixed contact parts are used for massage, then the device structure is simple, but the local stimulation is uneven and cannot cover a large area

Engineering Contradiction:
Improvecontact parts structureVSAvoidmassage coverage area
Core Design Contradiction:
Device complexityVSArea of stationary object

Solution Approach 1:

The patent converts fixed contact parts into dynamic moving balls driven by rotating screw rod. The balls continuously move along the spiral groove, enabling the system to cover extended areas and provide uniform distributed stimulation across large surfaces, effectively resolving the limitation of fixed contact parts.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent introduces rotational motion as an additional dimension to the traditional linear or static contact approach. The screw rod's rotation causes balls to traverse along its length, adding a temporal and spatial dimension to the massage coverage, thereby expanding the effective massage area beyond what fixed contact parts could achieve.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If simple vibration mode is used, then the device is easy to operate, but it cannot achieve deep muscle relaxation

Engineering Contradiction:
Improveoperation simplicityVSAvoidmassage effectiveness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements periodic peristaltic action through the rotating screw rod that rhythmically drives balls to contact and release the target tissue. This periodic compression and relaxation mimics natural physiological processes, providing deep muscle relaxation while maintaining simple automatic operation without complex user intervention.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The patent replaces simple vibration mechanics with a more sophisticated peristaltic pumping mechanism. The screw rod and balls create a mechanical system that delivers controlled, rhythmic compression forces, enhancing massage effectiveness for deep muscle relaxation while maintaining automatic operation that remains easy to use.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
