Resilient Retainer for Appliance Hinge Assembly to Prevent Deflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinge assemblies for appliances lack a secure and efficient mechanism to rotationally secure the hinge member within the hinge housing, leading to potential deflection and structural integrity issues during operation of the operable panel between open and closed positions.
Innovation Solution
A resilient retainer with a cap and integrally formed resilient portion is used to enclose the hinge housing, biasing the hinge member towards the cap and providing structural integrity by compressing within the housing to secure the pin and absorb rotational forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional hinge assembly is used without a resilient retainer, then the structure is simpler and easier to manufacture, but the hinge member is not securely retained leading to deflection and structural integrity issues
Solution Approach 1:
The hinge assembly is segmented into distinct functional components: the hinge member, the retainer, and the resilient portion. This segmentation allows each component to perform its specific function optimally while maintaining overall structural integrity through their coordinated interaction.
Solution Approach 2:
The resilient portion introduces dynamic characteristics to the hinge assembly by providing elastic deformation capability. This allows the assembly to absorb operational stresses and maintain secure retention under varying load conditions, transforming a static structure into a dynamically adaptive one.
2Reliability
If a resilient retainer is added to secure the hinge member, then structural integrity and retention are improved, but the device becomes more complex and harder to manufacture
Solution Approach 1:
The retainer and resilient portion are merged into a single integrated component rather than separate parts. This merging reduces the total number of components, simplifies assembly procedures, and decreases manufacturing complexity while maintaining the secure retention function.
Solution Approach 2:
The integrated retainer-resilient portion component performs multiple functions simultaneously: it secures the hinge member, absorbs operational stresses, provides elastic recovery, and maintains structural integrity. This multi-functionality reduces the need for additional specialized components.
3Reliability
If the resilient portion is compressed within the hinge housing, then the hinge is securely biased towards the cap, but the installation process becomes more difficult
Solution Approach 1:
The resilient portion is pre-compressed during the assembly process before final installation. This preliminary action allows the hinge member to be positioned and secured in the correct orientation, with the resilient portion already providing the necessary biasing force to ensure proper engagement.
Solution Approach 2:
The resilient portion acts as a pre-installed cushioning element that absorbs installation forces and protects the hinge member from damage during assembly. It provides a compliant interface that facilitates easier installation while ensuring secure retention once assembled.

AI summary
An operable panel for an appliance includes a top panel that defines a hinge receptacle. A lid includes a hinge housing. A hinge is disposed within the hinge housing and extends between the lid and the top panel. A retainer includes a cap and a resilient portion. The retainer partially surrounds the hinge and the cap encloses the hinge housing. The resilient portion of the retainer biases the hinge toward the cap and the hinge receptacle.
