Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional incandescent lighting or fluorescent bulbs are used, then illumination is provided, but the system lacks longevity and efficiency compared to LED technology

Engineering Contradiction:
ImprovelongevityVSAvoidconfigurable illumination patterns
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The illumination system is divided into multiple individual LED modules, each capable of independent directional adjustment. This segmentation allows each module to be optimized for longevity and efficiency while the collective system provides configurable illumination patterns through individual module positioning.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The LED modules are designed with rotatable mounts that enable dynamic adjustment of illumination direction. This dynamic capability allows the system to adapt illumination patterns to different applications while maintaining the inherent longevity and efficiency of LED technology.

Inventive Principle:
Principle #15Dynamics

2Use of energy by moving object

If light emitting diodes are used, then longevity and efficiency are improved, but the ability to provide configurable and adjustable illumination patterns is limited

Engineering Contradiction:
ImproveefficiencyVSAvoidconfigurable illumination patterns
Core Design Contradiction:
Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

Each LED module is designed as a universal unit that combines the energy-efficient LED light source with adjustable directional optics and rotatable mounting capabilities. This multi-functional design allows a single module type to serve multiple illumination needs while maintaining high energy efficiency.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The rotatable mount mechanism enables dynamic repositioning of each LED module, transforming the static LED light source into a dynamically adjustable illumination unit. This allows the system to provide configurable illumination patterns while preserving the energy efficiency of LED technology.

Inventive Principle:
Principle #15Dynamics

3Illumination intensity

If light is emitted in all directions, then maximum light output is achieved, but light spillage increases and directional illumination is lost

Engineering Contradiction:
Improvelight outputVSAvoidlight spillage
Core Design Contradiction:
Illumination intensityVSLoss of energy

Solution Approach 1:

The optic element extracts and redirects light from the omnidirectional LED emission, concentrating it into a directional beam. This extraction process removes the unwanted lateral light spillage while preserving and directing the useful light output toward the desired target area.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The optic acts as an intermediary between the LED light source and the target area, mediating the light transmission by refracting and reflecting light rays to achieve directional illumination. This intermediary element concentrates light output while minimizing energy loss to spillage.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A light module can comprise a light emitting diode that generates light and an optic that manipulates or manages the resulting light. The optic can direct the generated light off axis, resulting in an illumination pattern that is biased towards one side of the light module, for example in a desired direction. Thus, the optic can transform the emission pattern of the light emitting diode to create an illumination pattern that is aimed in a desired direction. The optic can comprise a light-blocking shield to suppress, manage, or redirect light that would otherwise emanate from the light module in an unintended direction, for example opposite the desired direction.
