Door-Hinge Mounted Cabinet Structure for Independent 135° Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture and storage solutions, such as cabinets and mirrors, are not effectively integrated with door hinges to provide flexible access and storage configurations, lacking the ability to pivot relative to doors for enhanced usability and space optimization.
Innovation Solution
Cabinets and mirrors are designed with multi-sectioned hinges supported by door hinges, allowing them to pivot about double and single hinge pins, enabling 135° arc movement and adjustable mounting for beveled sides, and featuring curvilinear back designs for increased shelf space and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a cabinet is hinged to the same hinges that support a door on a door frame, then the cabinet can be pivotally moved relative to the door to provide access while maintaining door functionality, but the hinge structure becomes more complex with multiple hinge sections and pins
Solution Approach 1:
The hinge structure is divided into multiple independent sections: a first hinge section attached to the door frame, a second hinge section attached to the cabinet, and a third hinge section connecting the door to the cabinet. This segmentation allows each section to function independently, enabling the cabinet to pivot relative to the door while the door pivots relative to the frame, thus providing flexible access without requiring a completely new complex hinge design.
Solution Approach 2:
The third hinge section acts as an intermediary element between the door and the cabinet. It mediates the relationship between these two components, allowing the cabinet to be attached to the door while maintaining independent pivotal movement capability. This intermediary hinge section resolves the complexity by providing a standardized connection point rather than requiring direct integration of the cabinet into the door hinge mechanism.
2Ease of operation
If the cabinet is designed with beveled sides to enable opening beyond 90°, then the cabinet can be fully opened to approximately 135° for better accessibility, but the manufacturing precision requirements increase
Solution Approach 1:
The cabinet sides are designed with asymmetric beveling rather than symmetric vertical sides. The beveled sides create an angular configuration that naturally guides the cabinet's movement arc, allowing it to open beyond the conventional 90° limit. This asymmetric geometry transforms the opening mechanism, enabling the cabinet to reach approximately 135° without requiring complex mechanical adjustments or high-precision manufacturing tolerances for hinge alignment.
3Adaptability or versatility
If multiple hinge sections are used to allow independent pivotal movement, then the cabinet can move through a 135° arc relative to the door, but the number of hinge pins and mounting points increases
Solution Approach 1:
The hinge system is segmented into three distinct sections, each with its own mounting points and pivot capabilities. The first hinge section mounts to the door frame, the second attaches to the cabinet, and the third connects the door to the cabinet. This segmentation allows independent pivotal movement of the cabinet relative to the door while using standardized hinge components rather than a single complex integrated hinge mechanism, thus managing the number of parts through modular design.
4Adaptability or versatility
If the cabinet is mounted on door hinges rather than fixed to the door, then the door functionality is maintained while the cabinet provides flexible access, but the mounting structure requires additional hinge sections
Solution Approach 1:
The third hinge section serves as an intermediary mounting element that attaches the cabinet to the door while preserving the door's independent functionality. This intermediary mounting structure allows the cabinet to be securely attached yet freely pivotable, providing flexible access without permanently fixing the cabinet to the door. The mounting structure's complexity is managed by using a standardized hinge section rather than a custom integrated mounting system.

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 sane 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.
