Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current retail lighting lacks dynamic 'white light illumination' solutions for mainstream display applications, relying on static white spectrum ambient lighting and theatrical color use, which limits the ability to create engaging and adaptive shopping environments.

Innovation Solution

Implementing a method and system using tunable spectrum lamps that cycle through different illumination spectra, creating periodic, repeating cycles to provide just-noticeable color accentuation and quasi-animation effects, thereby enhancing shopper engagement and browsing behavior.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If static white spectrum ambient lighting is used, then the lighting system is simple and reliable, but it cannot create engaging and adaptive shopping environments

Engineering Contradiction:

Improveadaptability of lighting to create engaging shopping environmentsVSAvoidcomplexity of lighting system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by transitioning from static ambient lighting to dynamic accent lighting that cycles through different color temperatures (e.g., 2000K warm white, 4000K neutral white, 6000K cool white) and intensities. This dynamic cycling creates visual interest and adapts to different shopping contexts while maintaining system reliability through controlled parameter changes.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent implements periodic action through cyclic illumination patterns where accent lights alternate between different color temperatures and intensities over time. This periodic variation in lighting parameters creates engaging visual effects that attract shopper attention without requiring permanently complex system architecture.

Inventive Principle:

Principle #19Periodic action

2Ease of operation

If concentrated accent lighting is used to focus attention on certain details, then visual attention is effectively directed, but the overall shopping atmosphere and mood are compromised

Engineering Contradiction:

Improveability to focus visual attention on merchandiseVSAvoidoverall ambient illumination quality

Core Design Contradiction:

Ease of operationVSIllumination intensity

Solution Approach 1:

The patent applies local quality by implementing accent lighting fixtures with specific color temperatures and intensities at particular locations (e.g., above product displays), while maintaining different ambient lighting conditions in other areas. This allows focused attention on specific merchandise while preserving overall shopping atmosphere through spatial differentiation of lighting characteristics.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If dynamic color-tunable lighting is used to create natural feelings of well-being, then customer experience is enhanced, but the system complexity and control requirements increase

Engineering Contradiction:

Improvecolor adaptation to different needs and moodsVSAvoidcomplexity of dynamic control system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by systematically varying color temperature (from 2000K to 6000K) and intensity parameters of accent lighting fixtures according to predetermined cycles. This approach enables color adaptation to different shopping contexts and moods while managing system complexity through structured parameter variation rather than uncontrolled adjustments.

Inventive Principle:

Principle #35Parameter changes

AI summary

Lighting methods and systems to enhance the browsing behaviors of shoppers in a manner intended to be primarily subconscious include illumination of a targeted area, such as a typical retail display, with a tunable spectrum lamp that slowly cycles through different illumination spectra such that color rendering of illuminated target is deliberately varied for subtle arousal of the visual senses. The illumination spectra, and the rates at which spectral conditions are changed, are both chosen as such that multi-colored objects in the targeted area change in appearance in a barely noticeable way, such that shoppers may find their visual attention redirected, seemingly at random, to a wider variety of products on display. Color spectrum changes also may be controlled in coordination with predefined packaging colors to create quasi-animation effects.
