Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If soft silicone is used to seal the sucking channel and generate negative pressure through deformation, then the device can provide a sucking force, but the deformation is limited and the negative pressure is relatively small, resulting in insufficient sucking force

Engineering Contradiction:

Improvesucking forceVSAvoiddeformation distance

Core Design Contradiction:

ForceVSLength of moving object

Solution Approach 1:

The patent removes the soft silicone sealing layer from the sucking channel and replaces it with a mechanical piston assembly. The piston assembly includes a piston that moves within a cylinder to directly generate negative pressure, eliminating the reliance on silicone deformation and providing stronger, more controllable sucking force.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the elastic deformation mechanism of soft silicone with a mechanical piston-cylinder system. The piston assembly uses direct mechanical movement to displace air and generate negative pressure, providing more forceful and controllable suction compared to the limited elastic deformation of silicone material.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If soft silicone is used to seal the sucking channel, then the device can maintain sealing, but due to fatigue feature of silicone material, the sucking force gradually decreases in long-time use

Engineering Contradiction:

Improvesealing performanceVSAvoidservice life

Core Design Contradiction:

ReliabilityVSDuration of action of moving object

Solution Approach 1:

The patent removes the soft silicone sealing layer that is prone to fatigue and replaces it with a mechanical piston assembly with a piston that moves within a cylinder. The piston and cylinder provide durable mechanical sealing through precision fitting, eliminating the fatigue issues associated with repeated elastic deformation of silicone material.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using a flexible sealing layer that deforms to create suction, the patent inverts the approach by using a rigid piston-cylinder mechanism where the piston moves to directly displace air and generate negative pressure. This mechanical approach provides more reliable long-term performance without material fatigue.

Inventive Principle:

Principle #13The other way round (Inversion)

3Force

If soft silicone is used to seal the sucking channel, then the device can provide initial sucking force, but the soft silicone may be damaged while movable components are used frequently for a long time

Engineering Contradiction:

Improvesucking forceVSAvoidmaterial durability

Core Design Contradiction:

ForceVSStrength

Solution Approach 1:

The patent removes the soft silicone sealing layer that is susceptible to damage from frequent mechanical operations and replaces it with a robust piston assembly. The piston and cylinder provide durable mechanical components that can withstand repeated use without degradation, maintaining consistent sucking force over time.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent inverts the traditional approach by replacing the flexible, damage-prone silicone sealing layer with a rigid mechanical piston-cylinder system. This mechanical structure provides superior strength and durability, enabling the device to withstand frequent and prolonged use without material damage.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

The present disclosure provides a clitoral sucker. The clitoral sucker includes: a housing, including a body and a sucking portion disposed on the body, where the body is provided with an inner cavity, and the sucking portion is provided with a sucking opening connected to the inner cavity; a negative pressure mechanism, including a piston assembly and a guide member, where the guide member is disposed in the inner cavity, the piston assembly is disposed in the inner cavity, partially extends into the guide member, and is configured to generate a negative pressure in the sucking opening. Due to the design of the piston assembly and the guide member, the piston assembly has a large movement path, and a greater negative pressure can be generated in the sucking opening. This significantly improves user experience.
