Solution Overview

Problem

Existing massage toys for sexual stimulation face issues such as mold growth due to inadequate drying, noise from motors or vacuum pumps, bulkiness, and a lack of discreet and easy-to-clean designs, while also lacking innovative stimulation mechanisms.

Innovation Solution

A massage toy with rotatable rod elements connected by a hinge assembly, allowing adjustable distance and angle, driven by a motor assembly for eccentric or centered motion, providing silent operation and easy cleaning, and featuring interchangeable rod elements for varied sensations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a sleeve-like structure is used to stimulate the penis, then the tactile features of the body opening are imitated, but the toy becomes difficult to clean and dry, leading to mold growth risks

Engineering Contradiction:
Improvetactile feature imitationVSAvoidmold growth prevention
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The toy is divided into multiple rod elements that can be independently positioned and adjusted. Instead of a single enclosed sleeve, the stimulation mechanism uses separate rods that can be spaced apart, allowing easy access for cleaning and drying between and around the elements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rod elements are arranged to be movable relative to each other, allowing the structure to open up for cleaning and drying. The hinge assembly enables the rods to be positioned in different configurations, including an open position that facilitates thorough cleaning and complete drying.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If electric motors or vacuum pumps are used for stimulation, then mechanical vibrations or vacuum effects are generated, but the operation becomes noisy

Engineering Contradiction:
Improvestimulation mechanismVSAvoidnoise
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent replaces electric motors and vacuum pumps with a purely mechanical linkage system. The hinge assembly and rod elements work together through mechanical advantage to generate the stimulation motion without requiring powered components, eliminating the noise associated with motors and pumps.

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

Solution Approach 2:

The mechanical linkage creates periodic motion through the oscillating movement of the rod elements. The hinge assembly converts linear or rotational input motion into periodic oscillations of the stimulation rods, providing rhythmic stimulation without continuous motor operation.

Inventive Principle:
Principle #19Periodic action

3Adaptability or versatility

If vacuum pumps or complex motor systems are incorporated, then stimulation functions are enhanced, but the toy becomes bulky and heavy

Engineering Contradiction:
Improvestimulation functionVSAvoidtoy weight
Core Design Contradiction:
Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The patent extracts and removes the heavy components (vacuum pumps, large motors, power supplies) from the system. The stimulation function is achieved through a lightweight mechanical linkage system that uses levers and hinges to amplify small input forces into effective stimulation motion.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The mechanical system uses dynamic movement and mechanical advantage to achieve effective stimulation with minimal mass. The rod elements and hinge assembly create leveraged motion that multiplies the effect of small input forces, eliminating the need for heavy powered components.

Inventive Principle:
Principle #15Dynamics

4Device complexity

If fixed rod positions are used, then the structure is simple, but the stimulation variety and user adaptability are limited

Engineering Contradiction:
Improvestructural simplicityVSAvoidstimulation variety
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The rod elements are designed to be adjustable and movable relative to each other through the hinge assembly. Users can change the spacing, angle, and position of the rods to create different stimulation patterns and intensities, providing versatility without requiring complex mechanisms.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mechanical linkage system serves multiple functions: it positions the rods, creates oscillating motion, and allows user adjustment. The same hinge assembly enables both the structural connection and the dynamic movement, providing multiple capabilities through a single integrated mechanism.

Inventive Principle:
Principle #6Universality (Multi-functionality)
