Solution Overview

Problem

Conventional door-mounted storage devices often damage door finishes, compromise structural integrity, and interfere with door closure, while being bulky and heavy, making them costly to ship and install.

Innovation Solution

A hinge-mounted cabinet assembled from modular sections using internal and external support channels with splines and caps, allowing weight support by existing door hinges, eliminating the need for door apertures and accommodating various hinge configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If conventional door-mounted storage devices are used, then storage capacity is provided, but the door's finish is damaged and structural integrity is compromised

Engineering Contradiction:

Improvestorage capacityVSAvoiddoor damage

Core Design Contradiction:

Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The cabinet is extracted from door-mounted configuration and repositioned to hinge-mounted configuration, removing the harmful interaction with the door surface while preserving storage function. The cabinet hangs from the hinge assembly rather than attaching to the door, eliminating finish damage and structural compromise.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The hinge assembly serves as an intermediary structure between the cabinet and the door. Instead of the cabinet directly interacting with the door (causing damage), the hinge acts as a mediator that supports the cabinet weight without compromising the door's integrity or finish.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Quantity of substance

If conventional door-mounted storage devices are used, then storage capacity is provided, but door closure is interfered with

Engineering Contradiction:

Improvestorage capacityVSAvoiddoor closure

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The cabinet is extracted from the door-mounted position where it interfered with door closure and repositioned to hang from the hinge. This removes the interference with the door jam and allows smooth door operation while maintaining storage functionality.

Inventive Principle:

Principle #2Taking out (Extraction)

3Quantity of substance

If conventional door-mounted storage devices are used, then storage capacity is provided, but the devices are bulky and heavy making shipping expensive

Engineering Contradiction:

Improvestorage capacityVSAvoidcabinet weight

Core Design Contradiction:

Quantity of substanceVSWeight of moving object

Solution Approach 1:

The cabinet material is changed from traditional heavy materials (wood, metal) to lightweight plastic through extrusion processes. This parameter change in material density reduces the cabinet weight and shipping costs while maintaining structural integrity and storage capacity.

Inventive Principle:

Principle #35Parameter changes

AI summary

A hinge mounted cabinet (1) that can be assembled from one or more sections (22) using a plurality of internal support channels (15) that are locked together using splines (23) and caps (31, 32) to form a main body (2) of the cabinet. An exterior support channel (39) allows hinge hanging brackets (40) to be easily positioned to accommodate various sized door and hinge configurations.
