Solution Overview

Problem

Conventional open front coolers consume significantly more energy than glass door merchandisers due to the lack of insulation, which may not be justified by the increased sales volume they provide, and supercooling coolers require precise temperature control to function effectively, leading to inefficiencies.

Innovation Solution

The indexing cooler features an insulated outer shell with rotating product zones defined by indexing wings equipped with brush seals, where one zone is exposed while the others remain refrigerated, using an indexing drive motor to alternate their positions, promoting impulse purchases while reducing energy costs and maintaining temperature consistency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If an open front cooler is used to provide easy product accessibility and promote impulse purchases, then consumer accessibility and sales volume are improved, but energy consumption increases significantly

Engineering Contradiction:
Improveproduct accessibilityVSAvoidenergy consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The cooler is divided into multiple independently controllable zones (first zone with open front, second zone with glass door, third zone that is refrigerated). This allows each zone to serve different functions - the open front zone provides easy accessibility for impulse purchases, while the other zones maintain energy efficiency through proper insulation and cooling, thus resolving the contradiction between accessibility and energy consumption

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different parts of the cooler have different thermal characteristics - the first zone has an open front for accessibility, while the second zone has a glass door for insulation, and the third zone is fully refrigerated. This local differentiation allows the system to provide easy access where needed while maintaining energy efficiency in other areas, resolving the contradiction between accessibility and energy consumption

Inventive Principle:
Principle #3Local quality

2Use of energy by moving object

If a glass door merchandiser is used to reduce energy consumption, then energy efficiency is improved, but product accessibility and impulse purchase potential decrease

Engineering Contradiction:
Improveenergy efficiencyVSAvoidproduct accessibility
Core Design Contradiction:
Use of energy by moving objectVSEase of operation

Solution Approach 1:

The cooler is divided into multiple independently controllable zones, with the first zone having an open front that provides easy accessibility for impulse purchases, while the second and third zones have glass doors for energy efficiency. This segmentation allows the system to provide both accessibility and energy efficiency simultaneously, resolving the contradiction

Inventive Principle:
Principle #1Segmentation

3Temperature

If supercooling techniques are used to cool beverages below freezing, then product cooling effect is improved, but temperature control precision requirements increase

Engineering Contradiction:
Improvecooling effectVSAvoidtemperature control precision
Core Design Contradiction:
TemperatureVSManufacturing precision

Solution Approach 1:

The cooler creates distinct thermal zones with the third zone being fully refrigerated and maintaining beverages below freezing for supercooling effects. By separating the supercooling function into a dedicated zone rather than applying uniform cooling, the system achieves the desired cooling effect while managing temperature control requirements through zoned management

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The indexing mechanism periodically rotates product zones between different thermal environments (open front, glass door, refrigerated zones). This periodic movement allows beverages to experience varying thermal conditions that facilitate supercooling while preventing uniform over-cooling, thus achieving the cooling effect with manageable temperature control precision

Inventive Principle:
Principle #19Periodic action
