Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If vision-based interaction is used to collect images of users or devices, then interaction capability is improved, but calculating complexity and hardware complexity increase

Engineering Contradiction:

Improveinteraction capabilityVSAvoidcalculating complexity and hardware complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces vision-based image collection with wireless signal-based interaction. Instead of using depth sensors to capture images and perform complex image processing, the system uses wireless signals to detect user actions through reflection echo features, substituting optical-mechanical systems with electromagnetic field-based systems that reduce computational and hardware complexity

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces wireless signals as an intermediary between the communication device and the user/another device. The wireless signals serve as a mediator that carries interaction information without requiring direct visual contact or complex image processing, simplifying the interaction pathway

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If wireless signals are used for interaction by detecting reflection echo features, then interaction capability is improved, but transmission distance is limited and recognition precision decreases

Engineering Contradiction:

Improveinteraction capabilityVSAvoidrecognition precision

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent segments the wireless signal transmission into multiple directional wave beams rather than using a single omnidirectional signal. By dividing the signal transmission into multiple directed beams, the system maintains signal strength and recognition precision over extended distances while covering broader interaction areas

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent makes the wireless signal system multi-functional by enabling it to operate effectively at both short and long distances through adjustable wave beam configurations. The system can adapt its signal transmission mode to serve different interaction scenarios, from close-range precise detection to long-range communication

Inventive Principle:

Principle #6Universality (Multi-functionality)
