Solution Overview

Problem

Existing household refrigeration appliances lack a cost-effective and versatile storage compartment front wall design that can be easily adapted for various uses, such as drawer fronts or pivoting flaps, which limits flexibility and efficiency in storage configurations.

Innovation Solution

A household refrigeration appliance with a storage compartment front wall that features bearing means for rigid attachment as a drawer front or pivotable flap between side walls, utilizing latching and hinge mechanisms for secure locking and easy conversion between drawer front and flap configurations, allowing for identical design storage compartment front walls in both forms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the storage compartment front wall is designed as a fixed drawer front, then the structure is simple and stable, but the adaptability and flexibility are limited

Engineering Contradiction:
Improveadaptability of storage compartment front wallVSAvoidcomplexity of front wall mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The storage compartment front wall is designed with universal bearing means that can accommodate multiple functions - serving as a fixed drawer front when locked, or as a pivotable flap when unlocked. The bearing means includes both locking mechanisms and hinge mechanisms, allowing the same component to perform different roles based on operational requirements.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The front wall transitions from a static fixed structure to a dynamic system that can change its state between fixed and movable. The bearing means enables the front wall to switch between being rigidly attached to the drawer container and being pivotable between side walls, providing dynamic adaptability to user needs.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the storage compartment front wall is designed as a pivotable flap, then the flexibility is improved, but the structural stability and ease of manufacture are reduced

Engineering Contradiction:
Improveflexibility of storage compartment front wallVSAvoidease of manufacture of front wall mechanism
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The same front wall design with bearing means serves both as a drawer front and a flap, eliminating the need to manufacture separate components for each function. The bearing means integrates both locking and hinge capabilities into a single manufacturable component.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The bearing means is segmented into distinct functional elements - locking mechanisms and hinge mechanisms - that can be independently manufactured and then assembled. This segmentation allows for easier manufacturing of complex functions by combining simpler, standardized components.

Inventive Principle:
Principle #1Segmentation

3Reliability

If different front wall designs are used for drawer fronts and flaps, then the functional requirements are met, but the cost and complexity increase

Engineering Contradiction:
Improvefunctional performance of front wallVSAvoidcomplexity of multiple front wall designs
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

A single universal front wall design with bearing means replaces the need for separate drawer front and flap designs. The bearing means provides both locking functionality for drawer fronts and hinge functionality for flaps, reducing the number of different designs to one while maintaining all required functional performances.

Inventive Principle:
Principle #6Universality (Multi-functionality)
