Solution Overview

Problem

Conventional shop window displays struggle to provide effective feedback to users selecting products due to limitations in visibility, especially in daylight, and require complex setups for multiple product highlighting, which can be cumbersome and obstructive.

Innovation Solution

An interactive system utilizing controllable light emitting surfaces, such as RGB LED arrays embedded in mats or surfaces, linked to RFID tags for automatic product detection and highlighting, allowing independent illumination of products with desired attributes, including color coding and adjustable intensity, to provide clear feedback on user selections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If spot lights are used for product highlighting, then product visibility is improved, but the number of spot lights required increases and their placement becomes complex and obstructive

Engineering Contradiction:
Improveproduct visibilityVSAvoidlight placement complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The system divides the shop window into multiple segments, with each segment containing a light source that can be independently controlled to highlight specific products. This segmentation allows multiple products to be highlighted simultaneously without requiring complex external light placement, as each segment self-contained lighting capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent combines the light source, control system, and display segment into an integrated unit. By merging these components, the system eliminates the need for separate spot light placements and achieves product highlighting through a unified, simplified structure where the light source is inherently part of the display segment.

Inventive Principle:
Principle #5Merging (Combining)

2Area of stationary object

If multiple spot lights are positioned close to each other for highlighting multiple products, then product coverage is improved, but light blockage between products increases

Engineering Contradiction:
Improveproduct coverage areaVSAvoidlight blockage
Core Design Contradiction:
Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

Each light source is positioned and directed to illuminate only its associated product or local area within the segment. This localized lighting approach ensures that light is concentrated on the intended target without being blocked by adjacent products, as each light source has its own optimized illumination path independent of neighboring segments.

Inventive Principle:
Principle #3Local quality

3Illumination intensity

If product layout is adjusted to accommodate spot light placement, then highlighting effectiveness is improved, but layout flexibility is reduced

Engineering Contradiction:
Improvehighlighting effectivenessVSAvoidlayout flexibility
Core Design Contradiction:
Illumination intensityVSAdaptability or versatility

Solution Approach 1:

The system incorporates electronically controllable light sources that can be dynamically adjusted in intensity, color, and timing through electronic control signals. This dynamic control allows the highlighting effectiveness to be optimized without physical repositioning of light sources or products, maintaining layout flexibility while achieving effective highlighting through electronic adjustment rather than mechanical reconfiguration.

Inventive Principle:
Principle #15Dynamics
