A display device that includes a display unit for three-dimensional display, a detection unit to detect body movements, and a control unit to perform operations based on detected displacements, allowing users to interact with virtual objects as if they were real by changing their position, rotation, or deformation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If stereoscopic display is used for viewing purposes, then viewing convenience is improved, but operational convenience remains unchanged

Engineering Contradiction:

Improveoperational convenienceVSAvoidfunctional versatility

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The display device integrates multiple functions by combining stereoscopic display capability with gesture-based interaction functionality. The detection unit enables the device to not only display three-dimensional images but also detect user gestures and execute corresponding operations, making the device adaptable to both viewing and operational tasks.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The detection unit acts as an intermediary between the user and the displayed object. By detecting gestures in the display space and translating them into control commands, the system enables natural interaction without requiring physical contact with the display surface or additional input devices.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If gesture detection is added to enable interaction, then operational convenience is improved, but device complexity increases

Engineering Contradiction:

Improveoperational convenienceVSAvoidsystem complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system replaces traditional mechanical interaction methods (such as physical buttons, switches, or direct touch) with gesture-based control. The detection unit captures gesture information in the display space, and the control unit processes these gestures to execute operations, eliminating the need for complex mechanical input mechanisms.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If real-time gesture detection and response is implemented, then user experience is improved, but processing requirements increase

Engineering Contradiction:

Improveoperational efficiencyVSAvoidprocessing power

Core Design Contradiction:

ProductivityVSPower

Solution Approach 1:

The system focuses detection resources on the display space where gestures are most relevant for interaction. By concentrating processing power on analyzing gestures within the three-dimensional display environment rather than monitoring the entire physical space, the system achieves real-time responsiveness with optimized computational resources.

Inventive Principle:

Principle #16Partial or excessive action
