Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If existing control systems (lighting desks, tablets, smartphone interfaces) are used to control LED lights, then the control interface is available and operational, but the control precision and responsiveness are insufficient for fine-scale parameter adjustment

Engineering Contradiction:

Improvecontrol precisionVSAvoiduser control intuitiveness

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The patent replaces traditional mechanical control interfaces (lighting desks with sliders and knobs, physical buttons) with a virtual reality-based gesture recognition system. Users control LED parameters through hand gestures captured by sensors, eliminating the need for physical manipulation of controls while achieving precise parameter adjustment through spatial and temporal analysis of gestures.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an intermediary processing layer between the user and the LED control system. This intermediary includes gesture recognition algorithms, virtual object representations, and a communication bridge that translates gestures into precise control commands, enabling intuitive interaction while maintaining control precision.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If existing control systems are used, then the basic control function is provided, but response delay occurs and fine-scale tuning capability is limited

Engineering Contradiction:

Improvecontrol response speedVSAvoidresponse delay

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent implements continuous monitoring of user gestures through sensors, maintaining constant analysis of hand position and movement. This continuous action eliminates idle states and processing delays, allowing real-time translation of gesture movements into immediate LED parameter adjustments, thereby reducing response time and enhancing control responsiveness.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The system performs preliminary processing of gesture data by continuously analyzing hand positions and movements before executing control commands. Virtual objects and gesture templates are pre-configured, allowing the system to quickly match and interpret user gestures without delay, enabling proactive rather than reactive control.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If multiple parameters (color, intensity, focus, position) are controlled simultaneously, then comprehensive control is achieved, but the complexity of organizing and executing these parameters in real-time increases

Engineering Contradiction:

Improveparameter control capabilityVSAvoidcontrol system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the control of multiple parameters into distinct virtual objects, each representing a specific LED parameter (color, intensity, focus, position). Users interact with each virtual object independently through separate gestures, allowing comprehensive parameter control while maintaining organizational clarity and reducing processing complexity through modular approach.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent transitions from traditional two-dimensional interface controls to three-dimensional spatial gestures. Users control multiple parameters simultaneously through gestures in three-dimensional space, where the spatial dimension provides an intuitive framework for organizing and executing complex parameter adjustments without increasing perceived interface complexity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

Disclosed are embodiments for systems and methods for controlling secondary devices at fine scales using mixed, virtual and/or augmented reality. Examples of secondary devices may include those involved in lighting (i.e., light emitting diodes), sound, and the production of videos, film, and movies. In some embodiments, a system may include a server, mixed reality user device and secondary device communicatively coupled via a network. The server may be configured to generate a virtual object based on gestural data that is configured for display within a mixed reality environment. The server may also be configured to generate secondary device settings based on gestural data, where the secondary device settings may be used to control the operation of a secondary device.
