Solution Overview

Problem

Existing strap-on sexual aid devices lack the ability to quickly, effectively, and safely change the sexual aid device from a harness during sexual activities, especially when switching to a device of different size, shape, length, or weight, and they often compromise hygiene due to complex components that accumulate dirt and bacteria.

Innovation Solution

A modular harness system comprising a set of customizable components with securement and coupling elements that allow for rapid exchange and secure attachment of sexual aid devices, ensuring ease of use, hygiene, and comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a modular harness system is used to enable quick exchange of sexual aid devices, then the ease of operation and adaptability are improved, but the device complexity increases due to multiple coupling elements and modular components

Engineering Contradiction:
Improvequick exchange of devicesVSAvoidmultiple coupling elements
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The harness system is divided into separate modular components including a harness body, coupling elements, and attachment mechanisms. This segmentation allows each component to be independently manufactured, cleaned, and replaced, enabling quick device exchange while maintaining overall system functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coupling elements are designed with universal interfaces that can accommodate different sexual aid devices of various sizes and shapes. The same harness body can securely attach multiple different devices through standardized coupling mechanisms, providing adaptability without requiring multiple specialized harnesses.

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

2Reliability

If complex components are used to secure the harness, then the reliability of attachment is improved, but hygiene deteriorates due to accumulation of dirt and bacteria in complex structures

Engineering Contradiction:
Improvesecure attachmentVSAvoiddirt and bacteria accumulation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The coupling elements are designed as separate, removable components that can be easily detached from the harness body. This extraction of the attachment function into discrete elements allows for thorough cleaning and sanitization of each component independently, preventing dirt and bacteria accumulation in complex structures.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The modular design allows coupling elements to be removed, cleaned, and reused. Contaminated components can be easily separated from the harness system for cleaning and sanitization, then recovered and reattached, maintaining hygiene while preserving the secure attachment function.

Inventive Principle:
Principle #34Discarding and recovering

3Ease of manufacture

If a fixed harness design is used, then the ease of manufacture is improved, but adaptability to different device sizes and shapes deteriorates

Engineering Contradiction:
Improvestandardized harness productionVSAvoidaccommodation of different device sizes
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The harness incorporates adjustable and flexible elements such as adjustable straps, movable coupling points, and flexible materials that can adapt to different device dimensions. This dynamic design allows a single standardized harness to securely accommodate various device sizes and shapes while maintaining ease of manufacture through modular components.

Inventive Principle:
Principle #15Dynamics
