Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional sex toys are used for sexual stimulation, then sexual pleasure can be obtained, but skin irritations and inflammations occur in the genital area

Engineering Contradiction:
Improvesexual pleasureVSAvoidskin irritation
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces conventional mechanical vibration stimulation with optical stimulation using LEDs that emit light at different wavelengths. The optical effect generating member with diffraction grating creates polychromatic optical effects that stimulate erogenous zones without direct mechanical contact, thereby avoiding skin irritation while maintaining sexual pleasure

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the stimulation parameter from mechanical vibration to optical wavelength variation. By using LEDs that emit multiple wavelengths (e.g., 450nm blue, 530nm green, 630nm red) and diffracting them through a grating, the system creates dynamic optical patterns that stimulate sensitive areas without the harmful mechanical friction caused by traditional toys

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If simple phallic-shaped sex toys are used, then ease of use is improved, but the device cannot accommodate diverse user physiologies and provides limited sexual pleasure

Engineering Contradiction:
Improveease of useVSAvoidaccommodation of user physiology
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent creates a universal stimulation device that can accommodate diverse user physiologies by using optical patterns instead of fixed mechanical structures. The programmable LED array can generate various optical patterns (scanning lines, rotating patterns, pulsing effects) that can adapt to different anatomical variations and user preferences, making the device versatile for different users without requiring multiple specialized toys

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

Solution Approach 2:

The patent introduces dynamic optical patterns that can change over time through programmable control. The LEDs can scan across different areas, rotate patterns, pulse at varying frequencies, and change wavelengths dynamically, allowing the device to adapt to different user needs and physiological responses during use, rather than being static like conventional toys

Inventive Principle:
Principle #15Dynamics
