Solution Overview

Problem

Conventional male sexual stimulation devices with reusable parts require extensive cleaning and disinfecting, pose safety risks if not properly cleaned, and can develop cracks over time, leading to ineffective sanitation and potential disease transmission.

Innovation Solution

A disposable, low-cost, user-made device using a mold assembly with a mold inner tube, outer tube, end caps, and a mold fluid composed of water and alginate powder, which can be quickly assembled, cured, and used as a genital sheath, providing a sterile and easily cleanable solution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If conventional stimulation devices use reusable parts, then device durability and reusability are improved, but cleaning complexity and disease transmission risk increase

Engineering Contradiction:
Improvedevice reusabilityVSAvoiddisease transmission risk
Core Design Contradiction:
Duration of action of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The patent applies the disposable principle by making the genital engaging portion a single-use component that is discarded after one use. This eliminates the need for repeated cleaning and disinfecting, thereby removing the risk of disease transmission from improper cleaning or wear cracks. The disposable nature ensures each use is sterile while maintaining device functionality through inexpensive replacement rather than complex cleaning protocols.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The device is segmented into a reusable motorized portion and a disposable genital engaging portion. This segmentation allows the critical hygiene component to be replaced frequently and cheaply, while the expensive motorized portion is reused. The separation enables independent disposal of the contaminated portion without wasting the functional motor component, resolving the contradiction between reusability and hygiene safety.

Inventive Principle:
Principle #1Segmentation

2Object-affected harmful factors

If conventional stimulation devices are extensively cleaned and disinfected, then hygiene is improved, but time consumption and potential damage to device structure increase

Engineering Contradiction:
Improvegerm exposureVSAvoidcleaning time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

By making the genital engaging portion disposable, the patent eliminates the time-consuming cleaning and disinfecting process entirely. Users simply discard the used portion and attach a new one, reducing cleaning time from potentially extensive procedures to a simple replacement action. This resolves the contradiction by making hygiene maintenance instantaneous rather than time-intensive.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent extracts the hygiene-critical genital engaging portion as a separate removable component that can be independently disposed of. This extraction allows the hygiene function to be maintained through simple replacement rather than complex cleaning procedures, eliminating the time loss associated with extensive cleaning while ensuring germ-free usage.

Inventive Principle:
Principle #2Taking out (Extraction)

3Duration of action of stationary object

If reusable parts are used over time, then device longevity is improved, but crack formation and wear marks increase making true cleaning impossible

Engineering Contradiction:
Improvedevice lifespanVSAvoidcleaning effectiveness
Core Design Contradiction:
Duration of action of stationary objectVSReliability

Solution Approach 1:

The patent applies the disposable principle to the genital engaging portion, which is manufactured at low cost and designed for single use. This eliminates the problem of crack formation and wear marks that compromise cleaning effectiveness, as each new portion is pristine and free from degradation. The low cost of the disposable portion makes this approach economically viable despite the reduced lifespan of individual components.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

By segmenting the device into reusable and disposable portions, the patent isolates the component subject to wear and contamination. The disposable genital engaging portion is replaced before cracks or wear marks can form, ensuring cleaning effectiveness is never compromised. The reusable motorized portion remains protected from direct contact with biological materials, maintaining its integrity over time.

Inventive Principle:
Principle #1Segmentation
