Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If lighting elements and speakers are arranged in predetermined configurations, then image display and sound presentation can be achieved, but flexibility and adaptability are limited

Engineering Contradiction:

Improveflexibility in arrangementVSAvoidsystem configuration complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system transitions from static predetermined configurations to dynamic random arrangements. Lighting elements and speakers are positioned randomly in space, and the control system dynamically determines their locations and assigns functions based on real-time spatial relationships rather than fixed pre-arranged positions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The invention adds a spatial dimension to the system by using three-dimensional positioning data (x, y, z coordinates) to determine element placement and functionality. Instead of two-dimensional array positions, the system operates in three-dimensional space, allowing elements to be placed anywhere within the spatial volume.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If fixed arrays of lighting elements are used for image display, then image presentation is achieved, but the system cannot adapt to random or dynamic arrangements

Engineering Contradiction:

Improvearrangement flexibilityVSAvoidlocation determination accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system incorporates feedback mechanisms where the controller receives location data from positioning signals emitted by lighting elements, processes this information to determine precise spatial coordinates, and uses this feedback to dynamically control which elements are activated and how they display images based on their actual positions.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The invention replaces mechanical positioning systems (physical mounting structures and fixed arrays) with electronic/optical positioning methods. Lighting elements emit positioning signals (such as infrared or radio frequency signals) that are detected and processed to determine their locations, eliminating the need for physical alignment and mechanical mounting precision.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If predetermined speaker arrangements are used for surround sound, then sound presentation is achieved, but adaptability to different spatial configurations is limited

Engineering Contradiction:

Improvespatial configuration adaptabilityVSAvoidinstallation complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system enables self-service installation where lighting elements and speakers automatically transmit their positioning information to the controller. The controller autonomously processes this data to determine optimal placement and functional assignment, eliminating the need for manual configuration or complex installation procedures by the user.

Inventive Principle:

Principle #25Self-service
