Hinge-Mounted Cabinet Using Modular Channels to Eliminate Door Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional door-mounted storage solutions often damage the door's finish, compromise its structural integrity, and interfere with door closure, while being heavy and costly for shipping and installation.
Innovation Solution
A hinge-mounted cabinet that uses internal and external support channels locked by splines and caps, allowing it to be pivoted independently of the door, eliminating the need for door-mounted apertures and supporting its weight through existing hinges, and is lightweight, modular, and easy to install on various hinge configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If storage devices are mounted directly to the door using screws, bolts and/or adhesives, then the storage is securely attached to the door, but the door's finish is damaged and structural integrity is compromised
Solution Approach 1:
The patent introduces hinges as an intermediary mounting mechanism. Instead of directly attaching storage to the door, the storage is mounted to the hinges which are already attached to the door. This intermediary approach transfers the attachment strength requirement from the door to the hinge system, preventing direct damage to the door while maintaining secure attachment.
Solution Approach 2:
The patent extracts the mounting function from the door itself and relocates it to the hinge system. By separating the storage attachment from direct door mounting, the door is spared from damage while the hinge system assumes the attachment role, resolving the contradiction between secure attachment and door preservation.
2Volume of stationary object
If conventional door mounted cabinets are made larger to provide more storage, then storage capacity increases, but shipping and transportation costs increase and weight added to the door increases
Solution Approach 1:
The patent applies dynamics by making the cabinet pivotable on the hinge pins, allowing the cabinet to move independently from the door. This dynamic mounting approach enables the cabinet to be suspended from the hinge mechanism rather than being rigidly attached, distributing weight more efficiently and reducing the effective load on the door while maintaining storage capacity.
Solution Approach 2:
The hinge system serves multiple functions: it provides the primary door hinge function and simultaneously serves as the mounting mechanism for the cabinet. This multi-functionality eliminates the need for separate heavy mounting hardware, reducing overall cabinet weight and shipping costs while maintaining secure attachment and adequate storage capacity.
3Ease of operation
If storage devices are mounted over the upper edge of doors on hooks, then installation is simple, but the door jam is interfered with and door closure is difficult
Solution Approach 1:
The hinge system acts as an intermediary that positions the cabinet away from the door edge. By mounting the cabinet to the hinges rather than directly over the door edge, the cabinet is positioned in a location that does not interfere with the door jam, eliminating closure interference while maintaining easy installation through the hinge mounting mechanism.
4Weight of moving object
If a cabinet is made modular with multiple sections to reduce shipping weight, then shipping costs decrease, but assembly complexity increases
Solution Approach 1:
The cabinet is divided into multiple modular sections that can be shipped separately and assembled on-site. This segmentation reduces individual package weight and shipping costs while allowing flexible assembly. The standardized hinge mounting interface simplifies the assembly process, preventing complexity from increasing despite the modular construction.

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.
