Solution Overview

Problem

Existing pivot hinge brackets for commercial refrigerator doors require multiple differently configured brackets for left and right-handed installations, complicating installation and necessitating a large number of parts, especially when door stops are involved.

Innovation Solution

A pivot hinge bracket assembly with two mirror-imaged main bracket portions and a removably coupled pivot plate, allowing for interchangeable installation regardless of handedness, reducing the required number of parts to two main bracket portions and an optional door stop.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional pivot hinge brackets are used with fixed configurations for left and right handed installations, then the door mounting function is achieved, but the number of required bracket types increases to four or six different configurations

Engineering Contradiction:
Improvedoor mounting adaptabilityVSAvoidnumber of bracket types
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The bracket is designed with a universal configuration that can accommodate both left-handed and right-handed door installations through a single standardized design, eliminating the need for multiple bracket types while maintaining full mounting functionality

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The bracket is divided into separate functional components including a mounting flange portion and a door stop portion, allowing each segment to be independently optimized and assembled in different configurations as needed for various installation scenarios

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple differently configured brackets are required for left and right handed installations with door stops, then all mounting scenarios are covered, but the inventory requirement increases to six different bracket types

Engineering Contradiction:
Improvemounting scenario coverageVSAvoidnumber of brackets in inventory
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

A single standardized bracket design serves multiple mounting scenarios including both left and right handed installations with and without door stops, reducing inventory requirements from six different bracket types to a universal configuration that handles all cases

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The bracket incorporates removable and reconfigurable components such as the door stop that can be positioned or removed based on installation requirements, allowing one bracket type to dynamically adapt to different mounting scenarios rather than requiring fixed configurations

Inventive Principle:
Principle #15Dynamics

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.
