Solution Overview

Problem

Refrigerators and freezers lack sufficient space for accommodating functional elements like bearings, closing dampers, and electronic components due to design constraints, limiting their functionality and aesthetic appeal.

Innovation Solution

A receiving element is detachably connected to the door, featuring recesses for bearings and electronic components, and extending into the protruding area outside the circumferential seal, allowing for the inclusion of closing dampers, cable guides, and power/data supply means, optimizing the use of the protruding space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If the door has a projecting section outside the sealing area to improve appearance, then aesthetic appeal is improved, but space for functional elements remains insufficient

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidspace for functional elements
Core Design Contradiction:
ShapeVSVolume of moving object

Solution Approach 1:

The receiving element utilizes the projecting section of the door (second area) that extends beyond the sealing area (first area) in the vertical dimension. By placing functional elements in this previously underutilized protruding region, the invention increases available space without compromising the aesthetic appearance that the projecting section provides.

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

Solution Approach 2:

The door structure is segmented into two distinct areas: the first area within the sealing circumference and the second area (projecting section) outside the sealing area. The receiving element is specifically positioned in the second area, separating functional element placement from the sealing function, thereby allowing both aesthetic appearance and functional space requirements to be met simultaneously.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If functional elements are integrated into the door structure, then functionality is improved, but the complexity of the door assembly increases

Engineering Contradiction:
ImprovefunctionalityVSAvoiddoor assembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The receiving element is designed as a separate, detachable component that can be independently manufactured and assembled. This segmentation allows the door assembly to be produced in modular sections, reducing overall assembly complexity while still integrating multiple functional elements (bearings, dampers, electronic components) into a unified structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The receiving element serves multiple functions simultaneously: it provides structural support for the door, accommodates bearings for pivotable movement, houses closing dampers, and integrates electronic components with power and data supply. This multi-functionality reduces the need for separate components, thereby reducing overall assembly complexity while enhancing functionality.

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

3Volume of moving object

If the receiving element extends into the protruding area, then space utilization is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvespace utilizationVSAvoidmanufacturing complexity
Core Design Contradiction:
Volume of moving objectVSEase of manufacture

Solution Approach 1:

The receiving element is designed as a detachable module that can be manufactured separately from the main door structure. This segmentation allows for simplified manufacturing of individual components using standard production techniques, while the final assembly achieves optimal space utilization by extending into the protruding second area of the door.

Inventive Principle:
Principle #1Segmentation
