Solution Overview

Problem

Commercial refrigerators are heavy, difficult to maintain, and do not align with modern design trends or consumer expectations, as they are typically large, heavy, and require customers to view merchandise from a single angle while exposing the refrigeration unit to dirt and debris, leading to increased maintenance costs.

Innovation Solution

A lightweight refrigerated merchandise display system with a modular design featuring a removable refrigeration unit positioned at the top, transparent front door assembly, and side windows for multi-angle viewing, using a plastic or metal outer housing with foam-based insulation and a hybrid convection-conduction refrigeration system, allowing for easy access and maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the refrigeration unit is positioned at the bottom of the refrigerator, then the refrigeration unit is exposed to dirt, debris and hazards that clog fans and mechanical parts, but this configuration increases maintenance and replacement costs

Engineering Contradiction:
Improvepositioning of refrigeration unitVSAvoidmaintenance and replacement costs
Core Design Contradiction:
Ease of operationVSEase of repair

Solution Approach 1:

The refrigeration unit is inverted from the conventional bottom position to the top position of the display system. This inversion resolves the technical contradiction by placing the refrigeration unit away from dirt and debris on the floor, thereby reducing clogging of fans and mechanical parts while lowering maintenance and replacement costs.

Inventive Principle:
Principle #13The other way round (Inversion)

2Strength

If the walls are formed from two thin steel plates with insulating polyurethane foam injected between them, then the construction is heavy and time-consuming to build, but this traditional construction method is difficult to recycle

Engineering Contradiction:
Improvewall constructionVSAvoidweight and construction time
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The display system is segmented into modular components including the outer housing, refrigeration unit, and shelving system. This segmentation allows for lighter-weight construction materials to be used while maintaining structural integrity, reduces construction time through pre-fabricated modules, and facilitates recycling by enabling separate disposal or reuse of individual components.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If customers can only view the product within a commercial refrigerator when standing in front of the refrigerator, then the viewing angle is limited, but this configuration does not provide visual access from a variety of angles

Engineering Contradiction:
Improvecustomer viewing capabilityVSAvoidviewing angles
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The display system incorporates side windows in addition to the front viewing area, transitioning from a single-dimension (front-only) viewing configuration to a multi-dimensional viewing configuration. This allows customers to view products from multiple angles including the front and sides of the display system, enhancing both ease of operation and adaptability.

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

4Stability of the object's composition

If the refrigeration unit is made heavy and fixed, then the structure is stable, but this makes the system difficult to maintain and replace

Engineering Contradiction:
Improvestructural stabilityVSAvoidaccessibility and replaceability of refrigeration unit
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The refrigeration unit is designed as a separate, modular component that can be easily detached from the display system. This segmentation maintains structural stability when assembled while enabling easy maintenance and replacement by allowing the refrigeration unit to be accessed and removed without disassembling the entire display system.

Inventive Principle:
Principle #1Segmentation
