Pivot hinge bracket assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pivot hinge brackets for commercial reach-in refrigerator doors require multiple differently configured brackets for various mounting positions, including left and right-handed configurations with and without pivot pins, and additional configurations for door stops, making installation complex and requiring a large number of brackets.
Innovation Solution
A pivot hinge bracket assembly with two mirror-imaged main bracket portions and a removably coupled pivot plate, allowing for interchangeable mounting positions and eliminating the need for multiple bracket types by using a modified square mounting hole that accommodates both pivot pins and screws, along with an optional door stop that can be easily secured.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple differently configured brackets are used for different mounting positions (left/right handed, with/without pivot pins, with/without door stops), then the bracket can accommodate all mounting configurations, but the number of bracket types increases from 2 to 6
Solution Approach 1:
The bracket is designed with a universal structure that can accommodate multiple mounting configurations (left/right handed, with/without pivot pins, with/without door stops) using a single bracket type. The key features include: (1) A square mounting hole that can receive both pivot pins and mounting screws interchangeably, (2) Symmetric design elements that allow the same bracket to be used for both left and right handed door configurations, (3) Optional door stop features that can be included or excluded without requiring different bracket types. This multi-functional design eliminates the need for six different bracket types while maintaining full adaptability to all mounting scenarios.
2Adaptability or versatility
If a square mounting hole is used instead of a round hole, then both pivot pins and mounting screws can be accommodated, but the mounting hole geometry changes
Solution Approach 1:
The square mounting hole serves as a universal interface that can accommodate both pivot pins (which typically have square cross-sections for anti-rotation) and mounting screws (which have circular shafts). The square geometry provides compatibility with both fastener types without requiring separate mounting holes or additional adapter components, thereby achieving multi-functionality in a single structural feature.

AI summary
A pivot hinge bracket assembly for use with a pivot hinge for a reach-in type cool room refrigerator includes two mirror imaged main bracket portions and a pivot plate removably coupled to one of the main bracket portions. The main bracket portion includes an edge mounting flange extending to a rear mounting flange mounted to the cool room refrigerator door jamb. The edge mounting flange has a modified square mounting hole and pivot pin plate screw mounting holes. The rear mounting flange has two door screw mounting holes. The pivot plate includes a pivot plate mounting flange and a pivot pin. The pivot hinge bracket assembly also includes an optional removably coupled door stop.
