Solution Overview

Problem

Conventional refrigeration devices with laterally mounted swivel joints for door racks limit design freedom, reduce storage space, and require manual tilting back, leading to discomfort and potential rubbing against internal components.

Innovation Solution

The swivel joint is positioned at the lower front edge of the receiving and holder parts, allowing the receiving part to automatically tilt back due to its weight, eliminating the need for manual intervention and increasing storage space by avoiding lateral obstructions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If lateral rotary joints are mounted in the middle of side walls, then the receiving part can be tilted for loading and unloading, but the storage space is reduced and the appearance is disrupted

Engineering Contradiction:
Improveloading and unloading comfortVSAvoidstorage space
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The rotary joint is relocated from the lateral middle position to the lower front edge position, changing the spatial dimension and location of the pivot point. This dimensional change allows the receiving part to tilt forward without lateral protrusions, maximizing storage space while maintaining tilting functionality for easy loading and unloading

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

2Ease of operation

If lateral rotary joints are mounted in the middle of side walls, then the receiving part can be tilted, but the geometric shape design freedom is limited

Engineering Contradiction:
Improvetilting movementVSAvoidgeometric shape design freedom
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The rotary joint is extracted from the lateral middle position and relocated to the lower front edge. This extraction eliminates the constraint that lateral joints impose on side wall geometry, allowing the receiving part and holder part to be designed with greater geometric freedom while still enabling necessary tilting movement

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If lateral rotary joints are mounted in the middle of side walls, then the receiving part can pivot, but manual tilting back is required causing discomfort

Engineering Contradiction:
Improvetilting capabilityVSAvoidmanual intervention requirement
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The lower front edge pivot position creates a configuration where the receiving part's weight naturally provides a restoring moment that automatically returns the receiving part to its closed position after tilting. This self-service mechanism eliminates the need for manual tilting back, improving operational comfort while maintaining full tilting capability

Inventive Principle:
Principle #25Self-service

4Adaptability or versatility

If lateral rotary joints are mounted in the middle of side walls, then the receiving part can be attached movably, but rubbing against internal components may occur

Engineering Contradiction:
Improvemovable attachmentVSAvoidrubbing against internal components
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

By relocating the rotary joint from lateral to lower front edge position, the tilting arc and movement path are changed to a forward-tilting motion. This dimensional change in pivot location ensures the receiving part moves clear of internal components in the door compartment, eliminating rubbing while maintaining movable attachment functionality

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

AI summary

At least one storage container (BE1) for a refrigerator (KG) comprises a stationary holder part (HT) and a receiving part (AT) which is movably mounted thereon and is used for storing products that are to be cooled. The receiving part (AT) is rotatably mounted on the holder part (HT) by means of at least one rotary joint (DS) in the region of the lower front edge (SK) of the receiving part (AT) in such a way that a net restoring torque (RM2) is applied to the receiving part (AT) in the respective opening position between the final closed position (SP) and the final open position (OP) of the receiving part (AT), said restoring torque (RM2) causing the receiving part (AT) to be automatically tilted back into the final closed position (SP).
