Solution Overview

Problem

LED and fluorescent light bulbs emit a cool blue or green hue, which is undesirable for residential use, as they have a narrow band of visible light compared to traditional incandescent lighting.

Innovation Solution

Hue-modifying wraps made from materials like polyvinyl, polyester, polyolefin, PVC, polyethylene, and polypropylene, which can be applied to light bulbs and configured to change their shape to adhere tightly, modifying the light's hue by incorporating indicia and adhesive properties to adjust the color emission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If LED and fluorescent light bulbs are used for residential lighting, then energy efficiency is improved, but the light emits a cool blue or green hue that is undesirable

Engineering Contradiction:

Improveenergy efficiencyVSAvoidundesirable cool blue or green hue

Core Design Contradiction:

Use of energy by moving objectVSObject-generated harmful factors

Solution Approach 1:

The patent introduces a hue-modifying wrap as an intermediary component between the light source and the environment. This wrap selectively transmits certain wavelengths while blocking others, mediating the interaction between the LED/fluorescent bulb and the surrounding space to produce a warmer, more desirable light hue without changing the underlying light source technology.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent directly applies color modification by using a wrap with specific optical properties that alter the perceived color of the light. The wrap is designed to block blue and green wavelengths while allowing red and yellow wavelengths to pass through, effectively changing the color temperature from cool (blue-green) to warm (red-yellow).

Inventive Principle:

Principle #32Color changes

2Object-generated harmful factors

If a hue-modifying wrap is applied to a light bulb, then the light's color hue is modified to be warmer, but the wrap must conform to the bulb's shape requiring transformation from 2D to 3D configuration

Engineering Contradiction:

Improvelight color hueVSAvoidwrap configuration transformation

Core Design Contradiction:

Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The patent employs a dynamic wrap design that transitions from a two-dimensional flat state during storage and application to a three-dimensional conformed state when wrapped around the bulb. The wrap includes transformation features such as score lines, adhesive regions, and flexible material properties that enable it to dynamically change its configuration from flat to curved, simplifying the application process while achieving proper fit.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent uses a flexible thin film material for the hue-modifying wrap that can be easily bent, folded, and conformed to the bulb's surface. This flexible film approach allows the wrap to adapt to various bulb shapes and sizes without requiring complex rigid structures, enabling simple application by wrapping and adhering the material to the bulb surface.

Inventive Principle:

Principle #30Flexible shells and thin films

3Reliability

If the hue-modifying wrap is made from materials like polyvinyl, polyester, or polyolefin, then the wrap provides durability and adhesive properties, but the material selection is limited to specific polymers

Engineering Contradiction:

Improvewrap durability and adhesionVSAvoidmaterial selection flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent specifies composite material construction for the hue-modifying wrap, combining a polymeric base material (such as polyvinyl, polyester, or polyolefin) with adhesive layers and potentially other functional coatings. This composite approach provides both the structural durability needed for long-term use and the adhesive properties required for secure attachment to the bulb surface, while the specification of multiple polymer options maintains material selection flexibility.

Inventive Principle:

Principle #40Composite materials
