Solution Overview

Problem

Conventional refrigerated cabinets often require additional support structures for their outer surfaces, which can complicate maintenance and energy efficiency, and do not allow for easy access or presentation of goods without opening the cold room, disrupting customer shopping experiences.

Innovation Solution

A self-supporting refrigerated cabinet design with shelves forming the structural support for cover elements, enabling the shelves to be walked upon and filled from inside, with transparent or partially transparent cover elements allowing external visibility of goods without opening the cold room, and a modular structure for flexible expansion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a separate skeleton support structure is used for the outer surface, then the structural stability is improved, but the device complexity and maintenance difficulty increase

Engineering Contradiction:
Improvestructural stabilityVSAvoiddevice complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent merges the support function into the shelves themselves, which are designed with sufficient structural strength to support both goods and the outer surface cover elements. This eliminates the need for a separate skeleton support structure, reducing device complexity while maintaining stability through the integrated shelf design.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If the cold room is opened for filling shelves, then the goods can be accessed and filled, but the temperature stability deteriorates and customer shopping experience is disrupted

Engineering Contradiction:
Improveease of fillingVSAvoidtemperature stability
Core Design Contradiction:
Ease of operationVSTemperature

Solution Approach 1:

The patent segments the filling operation from the customer shopping area by providing rear access to the cold room. Staff can fill shelves through a separate rear opening without disrupting customers or causing temperature fluctuations from frequent front door openings. The shelves are designed to be accessible from the rear for efficient restocking.

Inventive Principle:
Principle #1Segmentation

3Loss of information

If transparent cover elements are used for the outer surface, then the visibility of goods is improved, but the insulation performance may deteriorate

Engineering Contradiction:
Improvevisibility of goodsVSAvoidinsulation performance
Core Design Contradiction:
Loss of informationVSLoss of energy

Solution Approach 1:

The patent applies transparent cover elements selectively to the front display areas where visibility is needed for customer viewing, while other portions of the cold room can use opaque insulation materials. This local application of transparency maintains energy efficiency while providing necessary product visibility in display zones.

Inventive Principle:
Principle #3Local quality

4Volume of stationary object

If shelves are arranged close together for compact design, then the space utilization is improved, but the accessibility for filling and maintenance deteriorates

Engineering Contradiction:
Improvespace utilizationVSAvoidaccessibility
Core Design Contradiction:
Volume of stationary objectVSEase of operation

Solution Approach 1:

The patent provides accessibility to shelves through a rear dimension by creating a walkable space at the back of the cold room. Staff can access and fill shelves from this rear area without needing to open the front customer-facing doors, thus maintaining compact front dimensions while ensuring operational accessibility.

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

AI summary

The invention relates to a cooling assembly (100) comprising at least two shelves (2, 4) each having at least two supports (2.1, 2.2, 2.3, 2.4; 4.1, 4.2, 4.3, 4.4) and several shelves (2.5; 4.5) arranged thereon. The, shelves (2, 4) are mounted at a distance from each other thus forming an accessible intermediate chamber (10). The cooling assembly (100) also comprises several cover elements (20) which are secured to at least one of the shelves (2, 4) thus forming an outer surface of the cooling device (100).
