Solution Overview

Problem

Traditional cooler devices with integrated screens for promotion are expensive, inflexible, and obstruct product visibility, while alternative methods like stickers or billboards are aesthetically undesirable and require high effort to change.

Innovation Solution

A cooler device design featuring a transparent product presentation area and a separate, at least partly transparent display area that does not overlap, allowing unobstructed product visibility and enabling easy replacement of displays with a single glass sheet or gas-filled insulating glass units for improved aesthetics and energy efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If screens are integrated into the transparent area of the door for promotion, then display functionality is improved, but product visibility is obstructed and manufacturing complexity increases

Engineering Contradiction:
Improvedisplay functionalityVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The door is divided into separate functional areas: a transparent product presentation area and a display area with header structure. This segmentation allows the display functionality to be added without integrating screens into the transparent area, thus maintaining product visibility and simplifying manufacturing by separating the display system from the door glass assembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The display area is positioned in the header structure above the door rather than in the door panel itself. This spatial relocation to a different dimension (vertical space above the door) resolves the conflict between display functionality and product visibility, as the display no longer overlaps with the transparent area through which customers view products.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Illumination intensity

If light level is increased to achieve necessary contrast for displays, then display visibility is improved, but energy consumption increases significantly

Engineering Contradiction:
Improvedisplay visibilityVSAvoidenergy consumption
Core Design Contradiction:
Illumination intensityVSUse of energy by moving object

Solution Approach 1:

Lighting is localized to the display area in the header structure rather than illuminating the entire transparent door area. This targeted lighting approach provides sufficient contrast for display visibility while minimizing overall energy consumption by limiting the illuminated volume to only where promotional content is shown.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If digital displays are used in the cooled area, then display functionality is improved, but component reliability decreases due to condensation and humidity

Engineering Contradiction:
Improvedisplay functionalityVSAvoidcomponent reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The display area and its electronic components are extracted from the cooled area and positioned in the header structure above the door, which is outside the temperature-controlled zone. This relocation removes the display components from the harmful environment of low temperatures and high humidity, thereby improving reliability while maintaining display functionality.

Inventive Principle:
Principle #2Taking out (Extraction)
