Removable Door Hinge System With Keyway And Post Collar Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems make it burdensome to install and remove pivoting doors from their hinges, especially in tight spaces, due to difficulty in engagement and disengagement mechanisms.
Innovation Solution
A hinge system with cooperative attachments to the door frame and door, utilizing a keyway and counter bore mechanism at the header end and a post and collar system at the sill end to facilitate easy installation and removal by aligning and connecting hinge parts, allowing for tilting and rotational engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing hinge systems are used for pivoting doors, then the door can be installed and function, but the removal and reinstallation process is burdensome and difficult especially in tight spaces
Solution Approach 1:
The hinge system is divided into separate components: a hinge plate attached to the door frame, a hinge pin, and a hinge leaf attached to the door. This segmentation allows each component to be independently positioned and engaged, simplifying the overall installation and removal process while maintaining functional integrity.
Solution Approach 2:
The hinge pin acts as an intermediary element that connects the hinge plate and hinge leaf. By using this intermediate component, the system enables easy attachment and detachment of the door from the frame without requiring complex integrated mechanisms, thus improving ease of operation.
2Loss of time
If traditional hinge engagement mechanisms are used, then the door remains securely attached, but the process of removing and reinstalling the door becomes time-consuming and difficult
Solution Approach 1:
The hinge plate is pre-attached to the door frame and the hinge leaf is pre-attached to the door before the final assembly step. This preliminary positioning allows the door to be quickly installed or removed by simply engaging or disengaging the hinge pin, significantly reducing the time required for door maintenance operations.
Solution Approach 2:
The hinge system allows the door to transition dynamically between fixed (when pinned) and movable (when unpinned) states. This dynamic capability enables rapid installation and removal operations while maintaining secure attachment during normal use, addressing both time efficiency and operational ease.

AI summary
A hinge system includes first and second hinge assemblies. The first hinge assembly includes a first hinge plate with a post and a second hinge plate with a collar configured to selectively receive the post. The second hinge assembly includes a third hinge plate with a counter bore and a keyway and a fourth hinge plate with a key configured to be selectively received within the keyway and the counter bore.
