Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If complex laser imaging systems with multiple synchronized mirrors are used to project information, then image projection capability is achieved, but system reliability deteriorates under hazardous conditions

Engineering Contradiction:

Improveimage projection capabilityVSAvoidcontinuous operation under hazard conditions

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent extracts and eliminates the complex synchronized mirror system from the projection apparatus, replacing it with a single static beam director containing encoded surface geometry. This removal of complex moving parts directly addresses the reliability issue while preserving the core image projection function through the encoded geometric patterns on the beam director surface.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical synchronized mirror system with an optical encoding solution where images are formed by the geometric pattern of the beam director surface itself. This substitution eliminates mechanical complexity and electronic controls, achieving both simplicity and reliability while maintaining image projection capability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If complex electronic and mechanical controls are used to synchronize mirrors, then desired image generation is achieved, but device complexity increases

Engineering Contradiction:

Improvedesired image generationVSAvoidelectronic and mechanical controls

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent removes the complex electronic and mechanical control systems entirely, replacing them with a passively encoded beam director where the image information is embedded in the surface geometry itself. This extraction of control mechanisms directly reduces device complexity while maintaining image generation capability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using controls to dynamically adjust mirrors to create images, the patent inverts the approach by having the beam director's static encoded geometry directly form the images. The image is not created through active control but is inherently encoded in the beam director's physical structure.

Inventive Principle:

Principle #13The other way round (Inversion)

3Illumination intensity

If multiple colors and lasers are utilized in the projector, then image quality improves, but opportunity for malfunctions increases

Engineering Contradiction:

Improveimage qualityVSAvoidmalfunction risk

Core Design Contradiction:

Illumination intensityVSReliability

Solution Approach 1:

The patent extracts and eliminates the multiple laser and color control systems, replacing them with a single laser source and a beam director that encodes multiple images through its geometric surface patterns. This reduction to a single laser source dramatically reduces malfunction risk while maintaining the ability to project multiple images through the encoded geometry.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

In an illustrative embodiment, methods and systems for image projection include a beam director having a surface region geometrically encoded with an image such that, when a beam profile created from a beam strikes a portion of the surface region of the beam director, an altered beam profile is created incident to the portion of the surface region, where the altered beam profile has a light beam pattern configured to present a portion of the image, and the altered beam profile includes a predetermined beam spacing, a predetermined beam size, and a predetermined beam shape. The beam director may be configured to redirect predetermined beam profiles including the altered beam profile, incident across portions of the surface region of the beam director, as image beam patterns configured to strike a projection surface where the image is displayed.
