Modular Refrigerated Display With Top-Mounted Removable Cooling Unit
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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
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.
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
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.
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
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.
