Shared-Door Hinge Cabinet Mounting for Independent Swing Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cabinet and door hinge systems do not allow for independent pivotal movement of a cabinet relative to a door, limiting access and storage flexibility, and lack designs that integrate mirrors for enhanced functionality.
Innovation Solution
A cabinet design featuring multi-sectioned hinges with double and single hinge pins, allowing 135° arc movement, beveled sides for increased opening capacity, and adjustable shelving, along with the option for a fold-down work surface and integrated mirrors that can pivot independently or with the cabinet for enhanced accessibility and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a cabinet is mounted on the same hinges as a door, then space utilization is improved and storage is accessible in narrow spaces, but the cabinet and door cannot move independently limiting access flexibility
Solution Approach 1:
The hinge system is divided into multiple independent hinge sections (first hinge section on door, second hinge section on cabinet, third hinge section on door frame) connected by hinge pins. This segmentation allows the cabinet and door to be independently mounted and moved relative to each other, resolving the contradiction between space utilization and access flexibility.
Solution Approach 2:
The cabinet hinge sections are nested within the door hinge structure, with the cabinet's hinge sections fitting within the door's hinge assembly. This nested configuration allows the cabinet to be mounted in the door's hinge space, achieving compact space utilization while maintaining independent movement capability through the multi-section hinge design.
2Device complexity
If a single hinge pin is used for both door and cabinet, then device complexity is reduced, but the cabinet and door must move concurrently reducing operational independence
Solution Approach 1:
The hinge structure is segmented into multiple hinge sections (first, second, and third hinge sections) that can be connected by hinge pins. This segmentation allows operational independence while maintaining relatively simple construction through the modular hinge section design.
Solution Approach 2:
The hinge sections are designed with universal mounting capability, where the same hinge section design can be used for both door mounting and cabinet mounting. This multi-functionality reduces overall device complexity while enabling independent operation of the door and cabinet.
3Stability of the object's composition
If the cabinet is hinged to the door frame directly, then structural stability is improved, but the cabinet cannot pivot relative to the door reducing accessibility
Solution Approach 1:
The hinge system is segmented into door-mounted hinge sections and cabinet-mounted hinge sections, with the cabinet sections connected to the door frame through the door hinge structure. This segmentation provides structural stability through the door frame connection while enabling relative pivoting between cabinet and door.
Solution Approach 2:
The door-mounted hinge sections act as an intermediary between the cabinet and the door frame. This intermediary connection allows the cabinet to be indirectly supported by the stable door frame while maintaining the ability to pivot relative to the door, resolving the contradiction between structural stability and relative pivoting capability.

AI summary
A cabinet and a door are each provided with hinge sets having hinge parts secured thereto so that they can be separately mounted on the same hinge parts that are mounted on a door frame and are connected by a hinge pin for each hinge set that support the door on the door frame, using a single hinge pin for and as a part of each hinge set. With this mounting arrangement, the cabinet and the door of each such installation can move independently in an arc about the hinge pins connecting the door frame parts to the hinge parts fastened to the door and the hinge parts fastened to the cabinet without requiring the movement of the door concurrently with the movement of the cabinet.
