Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing door hinge attachments have limited capabilities and often interfere with door operation, causing damage, and are not suitable for storing items like paper towels or toilet paper rolls, which are commonly stored unsafely near toilets.

Innovation Solution

A hinge hanger system comprising a curved supporting connector, a hook component, and an arm component with an elastic base, which can be easily installed on door hinges to store items like paper towels and toilet paper rolls without interfering with door operation and includes modular accessories for expanded storage options.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If permanently installed hooks are used to attach items to doors, then the attachment capacity is limited and permanent attachment is achieved, but the door surface is marred and damaged

Engineering Contradiction:

Improveattachment capacityVSAvoiddoor surface damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a hinge hanger as an intermediary device between the door hinge and the items to be hung. Instead of directly attaching hooks to the door surface, the hinge hanger interfaces with the door hinge mechanism, distributing forces to the hinge hardware rather than the door surface, thereby preventing damage while maintaining attachment capacity

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention replaces the traditional screw-adhesive mechanical attachment system with a hinge-based mechanical system. The hinge hanger utilizes the existing hinge pin and knuckle mechanism, substituting direct door surface attachment with hinge mechanism attachment, which is designed to bear mechanical loads without damaging the door

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If over-the-door hangers are used to support brackets, then attachment to the door is achieved, but the door frame is damaged and door operation is interfered with

Engineering Contradiction:

Improveattachment capabilityVSAvoiddoor frame damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention extracts the attachment function from the door frame itself and relocates it to the door hinge mechanism. The hinge hanger takes out the bracket support function from the door frame structure and implements it through the hinge assembly, which is specifically designed to handle mechanical loads without compromising the door frame integrity

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A hinge hanger and accessory components are described. In a one illustrative embodiment, the hinge hanger includes a curved supporting connector, a hook component and an arm component. The curved supporting connector is configured to interface with a cylindrical component. Also, the curved supporting connector has a top lip that interfaces with the cylindrical component. Additionally, the curved supporting connector has a bottom end that interfaces with the cylindrical component. The hook component is disposed near the bottom end of the curved supporting connector. The arm component extends from the curved supporting connector. The arm component includes a vertical upright component proximate to a distal end of the arm component. The arm component also includes an elastic base at the distal end of the arm component.
