Appliance Door Bracket Assembly for Adjustable Gasket Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing appliance door adjustment systems lack flexibility in adjusting the position of the door relative to the appliance body, leading to issues such as frost formation and gasket sealing problems, and require replacement of components to address these issues.
Innovation Solution
A door adjustment assembly that includes a housing with a cavity, a driven member movable between positions, and a driving member that rotates to adjust the position of a bracket coupled with the door and rear panel, allowing the door to be adjusted to be parallel or at specific angles relative to the appliance body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the door is fixed in a static position, then the structure is simple and stable, but the door cannot be adjusted to prevent frost and gasket sealing problems
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed door structure into an adjustable one. The adjustment assembly includes a driven member that can move between multiple positions, allowing the door to be dynamically repositioned. The bracket is coupled to both the door and the driven member, enabling the door position to change relative to the appliance body while maintaining structural stability through the housing and mounting mechanisms.
2Reliability
If the door position is adjusted to prevent frost and gasket issues, then sealing performance improves, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the adjustment function into separate components: a housing that mounts to the appliance body, a driven member with multiple positions within the housing, and a bracket that couples the door to the driven member. This segmentation allows the adjustment mechanism to be integrated into the existing door assembly without requiring complete redesign, thereby improving sealing while limiting complexity increase.
3Reliability
If components are replaced to fix frost and gasket problems, then reliability improves, but loss of time and manufacturing cost increase
Solution Approach 1:
The patent applies preliminary action by providing an adjustment assembly that can be pre-configured with multiple driven member positions during manufacturing. This allows the door to be adjusted in the field without requiring component replacement, as the appropriate position is already available in the pre-built assembly. The bracket and housing are designed to accommodate position changes without requiring reassembly or replacement of major components.

AI summary
An appliance door assembly includes a front panel spaced apart from a rear panel. A door adjustment assembly is coupled with the rear panel and includes a housing that defines a cavity. A driven member is positioned within the cavity and extends at least partially from the housing. The driven member is movable between a first position and a second position. A driving member is rotatably engaged with the driven member and is configured to rotate the driven member. A bracket is coupled with the door adjustment assembly at a first end and coupled with the rear panel at a second end. The bracket abuts the housing of the door adjustment assembly when the driven member is in the first position and is spaced apart from the housing of the door adjustment assembly when the driven member is in the second position.
