Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a vibration motor is used to provide vibration to sensitive areas, then the device can stimulate the user, but the stimulation effect is poor and difficult to meet users' needs

Engineering Contradiction:
Improvestimulation effectVSAvoiduser needs satisfaction
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The sex toy is divided into multiple stimulation portions (first stimulation portion with first cavity, second stimulation portion with second cavity) that can independently accommodate and stimulate different areas of the male penis. Each portion has its own vibration member, allowing targeted stimulation of specific sensitive areas rather than uniform vibration, thereby improving stimulation effectiveness and meeting diverse user needs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different stimulation portions are designed with different cavity structures (first cavity with first massage finger, second cavity with second massage finger) to provide localized stimulation tailored to different anatomical areas. The vibration members are positioned to deliver vibration specifically to each cavity, creating varied stimulation qualities for different regions of the penis, thus enhancing overall user satisfaction.

Inventive Principle:
Principle #3Local quality

2Ease of operation

If hand holding is required during use, then control is precise, but operation convenience is reduced

Engineering Contradiction:
Improveoperation convenienceVSAvoidstructural simplicity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The stimulation portions are designed with flexible materials that allow dynamic adaptation to the user's anatomy during use. The cavities can flex and conform to the penis shape, providing secure accommodation without requiring rigid structural support or hand holding. This dynamic flexibility maintains structural integrity while enabling hands-free operation.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If single-area stimulation is provided, then the device structure is simple, but stimulation diversity is limited

Engineering Contradiction:
Improvestimulation diversityVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is segmented into multiple independent stimulation portions, each capable of providing vibration to different areas. This segmentation enables diverse stimulation patterns without requiring an overly complex overall structure, as each portion remains relatively simple but collectively they provide comprehensive coverage of sensitive areas.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each stimulation portion serves multiple functions: accommodation of penis tissue, localized vibration delivery, and flexible adaptation to different anatomical variations. This multi-functionality allows the device to provide diverse stimulation experiences while maintaining a relatively simple design for each individual portion.

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

AI summary

A sex toy includes a flexible first stimulation portion, a vibration member and a flexible second stimulation portion. The flexible first stimulation portion includes a first massage finger provided on a first side and a second massage finger provided on a second side opposite to the first side. The first massage finger extends toward the second side, the second massage finger extends toward the first side, and the first massage finger and the second massage finger cooperatively enclose a first cavity. The vibration member is provided at the flexible first stimulation portion. The flexible second stimulation portion is provided at one end of the first stimulation portion and provided with a second cavity. The first cavity is communicated with the second cavity to collectively form a stimulation chamber for accommodating a male penis.
