Locking Hinge Bracket Assembly for Fast Secure Door Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinge bracket assemblies for appliance doors lack a secure and efficient mechanism for coupling the hinge plate with the anchor plate, leading to potential instability and difficulty in assembly and disassembly.
Innovation Solution
A hinge bracket assembly featuring an anchor plate with a retention member and stop, a hinge plate with a protrusion, and a locking arm that is rotatable between unlocked and locked positions, allowing the hinge plate to be securely coupled with the anchor plate through aligned receiving apertures and a wrapper receiving aperture, eliminating the need for screws or fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional screw or fastener mechanism is used to couple the hinge plate with the anchor plate, then the connection is secure, but the assembly and disassembly process becomes time-consuming and complex
Solution Approach 1:
The locking arm is designed to be rotatable between unlocked and locked positions, transforming a static fastening system into a dynamic one. This allows the hinge plate to be quickly secured or released by simply rotating the locking arm, eliminating the need for screws or multiple fasteners and significantly reducing assembly time
Solution Approach 2:
The coupling mechanism is divided into distinct functional components: the locking arm for securing, the receiving aperture for alignment, and the stop for positioning. This segmentation allows each component to perform its specific function efficiently, enabling quick assembly through simple alignment and rotation rather than complex fastening procedures
2Productivity
If a simple alignment mechanism is used without a locking arm, then the assembly process is quick, but the connection becomes unstable and prone to inadvertent movement
Solution Approach 1:
The locking arm provides a dynamic locking mechanism that can be quickly engaged or disengaged. When rotated to the locked position, it securely holds the hinge plate against the anchor plate, providing stability without compromising assembly speed. The rotatable nature allows for rapid engagement while maintaining a secure connection
Solution Approach 2:
The locking arm acts as an intermediary element between the hinge plate and anchor plate. It mediates the connection by providing both alignment guidance through the receiving aperture and secure locking through its rotatable engagement, ensuring both quick assembly and stable connection
3Reliability
If multiple fasteners or complex coupling mechanisms are used, then the connection is very secure, but the device complexity increases and manufacturing becomes more difficult
Solution Approach 1:
The locking arm combines multiple functions into a single component: alignment guidance through the receiving aperture, positioning through the stop, and secure locking through rotatable engagement. This merging eliminates the need for multiple separate fasteners or complex coupling mechanisms while maintaining reliable security
Solution Approach 2:
The locking arm serves multiple purposes: it guides alignment during assembly, positions the hinge plate correctly using the stop, and provides secure locking when rotated to the locked position. This multi-functionality reduces the number of components needed while ensuring reliable coupling

AI summary
A hinge bracket assembly includes an anchor plate. A retention member extends perpendicular to the anchor plate. The anchor plate defines a first receiving aperture. A hinge plate is aligned with the anchor plate and includes a hinge arm and a protrusion. The protrusion extends from an edge of the hinge plate opposite the hinge arm. The hinge plate defines a second receiving aperture aligned with the first receiving aperture when the protrusion is received by a space defined by the retention member. A locking arm is rotatable between an unlocked position and a locked position and is configured to be at least partially received by the first and second receiving apertures to couple the anchor plate and the hinge plate.
