Appliance Door Hinge Assembly With Adjustable Flange And Guide Wings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hinge assemblies for appliances have limited adjustability, failing to accommodate variations in doors and cabinets, and are not versatile across different appliance types.
Innovation Solution
An adjustable hinge assembly featuring a hinge arm with a flange that fits into connector slots on the appliance body, coupled with a guide having wings that prevent horizontal movement, allowing for precise alignment and adjustment of the door relative to the cabinet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional hinge assemblies are used, then the structure is simple, but the adjustability is limited and cannot accommodate variations in doors and cabinets
Solution Approach 1:
The hinge assembly is divided into multiple independent components: a hinge arm with a flange, a connector slot in the appliance body, a guide with wings, and a fastener. This segmentation allows each component to perform a specific function while collectively providing extensive adjustability. The flange can be positioned at multiple locations within the connector slot, and the guide with wings provides additional alignment options, enabling the hinge to accommodate various door and cabinet configurations.
Solution Approach 2:
The hinge assembly is designed as a universal solution that can be used across different appliance types and configurations. The connector slot and guide structure provide multiple adjustment positions, allowing the same hinge assembly to accommodate variations in door sizes, cabinet depths, and installation locations. This multi-functional design eliminates the need for different hinge models for different applications.
2Adaptability or versatility
If the hinge assembly allows extensive adjustment, then adaptability improves, but the complexity of the assembly increases
Solution Approach 1:
Multiple adjustment functions are merged into a single integrated assembly. The hinge arm incorporates both the pivoting mechanism and the adjustable flange position within one component. The guide with wings combines alignment guidance and positioning functions in a single structure. This merging reduces the number of separate parts needed while maintaining extensive adjustability.
Solution Approach 2:
The connector slot acts as an intermediary element between the hinge arm and the appliance body, enabling adjustable positioning. The slot receives the flange and allows it to be positioned at multiple locations, providing adjustment capability without requiring multiple separate mounting mechanisms. This intermediary structure simplifies the overall assembly while maintaining versatility.
3Stability of the object's composition
If the guide with wings is used to prevent horizontal movement, then stability improves, but the device complexity increases
Solution Approach 1:
The guide structure provides stability specifically in the horizontal direction where it is most needed, while allowing free movement in the vertical direction for adjustment purposes. The wings of the guide are positioned to constrain horizontal movement of the flange, but do not interfere with vertical positioning. This localized constraint approach provides necessary stability without over-constraining the system.
Solution Approach 2:
The guide structure transitions from a static constraint to a dynamic adjustment mechanism. During installation, the flange can be moved vertically along the guide to achieve proper alignment. Once positioned, the wings engage to prevent horizontal movement, providing stability. This dynamic behavior allows the same structure to facilitate adjustment and then provide constraint.

AI summary
An appliance includes an appliance body defining a cavity. A front panel defines a connector slot. A hinge arm is configured to be pivotally coupled with the appliance body and includes an arm body defining an arm receiving well. A flange extends from the arm body and is configured to be received by the connector slot. A door includes a rail defining a rail receiving well and a channel configured to receive the hinge arm so that the rail receiving well is aligned with the arm receiving well. A fastener is configured to be received by the arm and rail receiving wells to fixedly couple the hinge arm within the channel of the rail. A guide is coupled with the front panel and defines an aperture aligned with the connector slot. First and second wings are configured to frame the flange when the flange is received by the connector slot.
