Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the cup diameter is fixed, then the structure is simple and easy to manufacture, but the stimulation manner is single and monotonous

Engineering Contradiction:
Improvestimulation manner diversityVSAvoidcup structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the cup diameter adjustable rather than fixed. The control structure can dynamically change the inner diameter of the cup body, transforming it from a static structure to a dynamic one. This allows the masturbator cup to adapt to different usage scenarios and provide varied stimulation manners, directly resolving the contradiction between structural simplicity and stimulation diversity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by enabling the cup diameter to vary between a first diameter and a second diameter through the control structure. This parameter adjustment capability allows the device to provide different stimulation intensities and patterns, enhancing adaptability while maintaining a relatively simple overall structure through controlled parameter variation.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the cup diameter is adjustable, then the stimulation experience is diversified, but the structure becomes more complex

Engineering Contradiction:
Improvestimulation experience diversityVSAvoidcup structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control structure introduces dynamic adjustability to the cup body, enabling the diameter to change between first and second diameters. This dynamic feature provides diversified stimulation experiences while the control structure is designed to be integrated and efficient, minimizing the increase in overall device complexity.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If a control structure is added to adjust the inner diameter, then the stimulation variety increases, but the device complexity increases

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

Solution Approach 1:

The control structure is designed to perform multiple functions: adjusting the inner diameter of the cup body, creating negative pressure within the cavity, and controlling the deformation of the soft colloid. By integrating these functions into a single control mechanism, the patent increases stimulation variety while minimizing the increase in device complexity.

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

Solution Approach 2:

The patent utilizes pneumatic principles by using the control structure to generate negative pressure within the cavity formed by the cup body and outer cylinder. This negative pressure control enables the soft colloid to deform and provides adjustable stimulation, achieving enhanced functionality through a relatively simple pneumatic control mechanism.

Inventive Principle:
Principle #29Pneumatics and hydraulics

AI summary

A negative pressure masturbator cup includes an accommodating cavity, a cup main body, and a control structure. The accommodating cavity is configured to accommodate a soft colloid. The cup main body has an elastically deformable body. The control structure has a negative pressure generator. When the control structure controls the negative pressure generator to generate a negative pressure, the soft colloid is pulled by the negative pressure generated by the negative pressure generator, and the elastically deformable body is deformed in a direction towards the accommodating cavity.
