Solution Overview

Problem

Existing door compartments for household refrigeration appliances lack flexibility in front-side configuration and have complex assembly processes, with components often being difficult to position and secure relative to each other.

Innovation Solution

A door compartment design featuring a base body with forward-oriented upper and lower brackets allows for the attachment of additional parts in a non-destructive manner, providing a flexible and secure fastening mechanism, and can be made with U-shaped brackets for enhanced stability and positional security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a one-piece container-like base body is used, then the basic structure is simple, but the front area cannot be changed and variant formation is limited

Engineering Contradiction:
Improvebase body structureVSAvoidfront area configuration
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The door rack is divided into a base body and separate additional parts (front panel, side panels). The base body remains simple and unchanged, while the additional parts can be detached and replaced to create different variants. This segmentation allows the front area to be modified without changing the basic container structure.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple separate elements are used for the door compartment, then variant formation is possible, but the assembly becomes complex and components are difficult to position securely

Engineering Contradiction:
Improvevariant formationVSAvoidassembly process
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The additional parts (front panel, side panels) are extracted as separate detachable components from the base body. These parts can be removed and replaced independently, allowing variant formation without assembling entire door compartments. The connection elements (brackets, recesses) enable simple attachment and detachment operations.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If simple attachment methods are used, then assembly is easy, but the positioning and securing of components relative to each other is restricted

Engineering Contradiction:
Improveassembly easeVSAvoidcomponent positioning
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

Connection elements are placed at specific locations (upper and lower brackets on the base body, corresponding recesses on additional parts) to provide secure positioning. The brackets extend forward from the rear wall at different heights, creating localized connection points that ensure proper alignment and stable attachment without requiring complex assembly procedures throughout the entire structure.

Inventive Principle:
Principle #3Local quality
