Refrigeration unit door bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigeration units lack a robust and efficient mechanism for securely attaching the door to the hinge, which can lead to instability and reduced structural integrity.
Innovation Solution
A bracket system is introduced that connects the door to the hinge, featuring multiple portions fixed to different surfaces of the door and a tab with a tang that extends over the second surface, allowing for secure attachment and alignment with an aperture for fastener insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple door attachment mechanism is used, then the device complexity is reduced, but the structural integrity and stability of the door connection deteriorates
Solution Approach 1:
The bracket is divided into multiple portions (first portion, second portion, third portion) that are fixed to different surfaces of the door, creating a segmented attachment system that distributes structural loads across multiple connection points while maintaining overall structural integrity
Solution Approach 2:
The bracket extends in multiple spatial dimensions by fixing portions to different surfaces (front surface, side surface, rear surface) of the door, creating a three-dimensional attachment structure that enhances stability without significantly increasing complexity
2Strength
If a robust bracket system with multiple portions is used, then the structural integrity is improved, but the device complexity increases
Solution Approach 1:
Multiple bracket portions are merged into a single integrated bracket structure that connects the door to the hinge, combining multiple attachment functions into one unified component that reduces overall device complexity while maintaining structural integrity
Solution Approach 2:
The bracket serves multiple functions simultaneously: it provides structural support, enables door attachment to the hinge, and distributes mechanical loads across multiple surfaces, making it a multi-functional component that justifies its structural complexity
3Ease of operation
If the aperture is vertically aligned with the tab, then the ease of operation for fastener insertion is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The aperture is pre-positioned and vertically aligned with the tab during bracket manufacturing, so that when assembly occurs, the fastener can be directly inserted without requiring complex alignment procedures, thereby improving ease of operation
Solution Approach 2:
The tab acts as an intermediary element that guides the fastener into the aperture during assembly, mediating the alignment process and reducing the precision requirements for the aperture position while maintaining ease of operation

AI summary
A refrigeration unit includes a cabinet that defines a storage cavity, a door pivotably coupled to the cabinet via a hinge and configured to selectively cover an opening to the storage cavity, and a bracket that connects the door to the hinge. The door includes a first surface, a second surface adjacent to the first surface, and a third surface adjacent to the first and second surfaces. The bracket includes a first portion fixed to the first surface, a second portion fixed to the second surface, and a third portion fixed to the third surface.
