Method for adjusting the position of a door of a household refrigeration appliance, and household refrigeration appliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household refrigeration appliances face challenges in precisely aligning door positions, leading to uneven gaps and a visually disadvantageous appearance, which can restrict finger insertion and cause deflection or rubbing during door movement.
Innovation Solution
A method for adjusting the position of a door on a household refrigeration appliance using a tool inserted into a gap between the door and the housing, allowing for precise readjustment of the door's position through a readjustment element accessible from the side or top, utilizing a bearing device with a pivotable bearing angle adjustment plate and base plate, and a locking screw for fixing the adjusted position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the door placement is precisely aligned with the housing during manufacturing, then the visual appearance is improved and gaps are uniform, but the device complexity increases and adjustment becomes difficult
Solution Approach 1:
The door adjustment system is segmented into multiple independent components: the door leaf, the bearing device with adjustment plate, and the readjustment element. This segmentation allows the door position to be adjusted independently without affecting the entire door assembly, enabling precise positioning while maintaining ease of operation through simple, modular components.
Solution Approach 2:
The readjustment element is designed to be accessible from the front through the gap between the door and housing, allowing users to perform adjustments themselves without requiring disassembly of cover parts or specialized tools. The gap itself serves as the access channel, enabling self-service adjustment by the end user.
2Ease of operation
If the readjustment element is made accessible through the gap, then the ease of operation is improved, but the readjustment element becomes vulnerable to damage or loss
Solution Approach 1:
The readjustment element is nested within the gap structure itself, which acts as a protective cavity. The gap serves dual purposes: it provides access for tool insertion while simultaneously accommodating and protecting the readjustment element. The bearing device structure creates a nested arrangement where the adjustment plate and readjustment element are housed within the door assembly framework.
Solution Approach 2:
The tool acts as an intermediary between the user and the readjustment element. The tool is inserted through the gap, engages with the readjustment element, and transfers the adjustment force. This intermediary mechanism allows the readjustment element to remain protected within the gap while still being accessible for operation through the mediating tool.
3Reliability
If extensive cover parts are removed to access the readjustment element, then the reliability of access is improved, but the loss of time increases
Solution Approach 1:
The readjustment function is extracted from the interior of the door assembly and positioned within the gap between the door and housing. This extraction eliminates the need to remove cover parts or disassemble components to access the readjustment element. The gap, which naturally exists for other functional purposes, is utilized as the access channel, saving time while maintaining reliable access.
Solution Approach 2:
The gap is preliminarily designed and positioned to serve dual functions: its primary function for door operation and its secondary function as an access channel for the readjustment element. This preliminary arrangement of the gap structure enables direct access to the readjustment element without requiring additional disassembly steps, reducing adjustment time while ensuring reliable access.

AI summary
A method for adjusting a position of a door on a housing of a household refrigeration appliance to change a placement of the door while located on the housing, includes separating a door leaf of the door from a front flange of the housing in a depth direction of the household refrigeration appliance by a gap in a closed state of the door. A tool is inserted into the gap and a readjustment element, which can be accessed through the gap, is readjusted by using the tool in such a way that the position of the door relative to the housing is changed in dependence on the readjustment of the readjustment element. A household refrigeration appliance is also provided.
