Solution Overview

Problem

Conventional moving head light fixtures have limited degrees of freedom for the movement of the head relative to the base, restricting flexibility and ease of replacement.

Innovation Solution

A moving head light fixture with a spherical head and a base featuring omni wheels that provide unlimited rotation in three degrees of freedom (yaw, pitch, and roll) without a fixed mechanical connection, allowing for enhanced flexibility and ease of head replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a fixed mechanical connection is used between the base and head, then structural stability is improved, but the degree of freedom for head movement is limited

Engineering Contradiction:

Improvestructural stabilityVSAvoiddegree of freedom for head movement

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent replaces the traditional fixed mechanical connection system with an omniwheel-based mechanical system. The omniwheels provide support and enable unlimited rotation in three degrees of freedom while maintaining structural stability through controlled mechanical contact points between the spherical head and the base.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of manufacture

If a fixed mechanical connection is used between the base and head, then manufacturing simplicity is improved, but flexibility for head replacement is reduced

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidflexibility for head replacement

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent segments the light fixture into two independent replaceable components: a base and a spherical head. The omniwheel mechanism enables the head to be easily detached and replaced without affecting the base structure, while maintaining manufacturing simplicity through standardized interfaces and modular design.

Inventive Principle:

Principle #1Segmentation

3Device complexity

If traditional pan and tilt mechanism is used, then device complexity is reduced, but the range of motion is limited

Engineering Contradiction:

Improvemechanism complexityVSAvoidrange of motion

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent employs a spherical head design that contacts the base through omniwheels, enabling rotation in three degrees of freedom (pan, tilt, and roll) without the complex multi-axis mechanisms of traditional systems. The spherical geometry naturally provides unlimited rotational range while keeping the mechanism relatively simple through the omniwheel support system.

Inventive Principle:

Principle #14Spheroidality (Curvature)
