Multi-Axis Door Hinge System for Wide Access

Solution Overview

Problem

Existing secure door and door jamb arrangements with a 90° swinging arc restrict access due to the door partially blocking the entrance when fully opened, limiting the effectiveness of resistance to forced entry.

Innovation Solution

A multi-axis door hinge system with a first hinge set on the external side and a second hinge set on the internal side, allowing both lateral and rotational movements, enabling the door to swing beyond 180° and providing improved clearance for access while maintaining security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the door swings open to 90° to maintain security resistance, then forced entry resistance is improved, but access clearance is restricted because the door partially blocks the entrance

Engineering Contradiction:

Improveforced entry resistanceVSAvoidaccess clearance

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces a second hinge axis that is non-coaxial with the first hinge axis, enabling the door to move in multiple dimensions. The door performs both lateral movement (translation) and rotational movement, allowing it to clear the door jamb zone completely when opened, rather than being constrained to a single 90° swing arc in one dimension.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The door hinge system allows the door to dynamically adjust its movement path between lateral translation and rotation based on the opening angle. The door can translate sideways to overlap the door jamb when closed for security, then rotate and translate to clear the jamb zone when opened for access, providing adaptive movement throughout the opening sequence.

Inventive Principle:

Principle #15Dynamics

2Strength

If the door translates sideways to overlap the door jamb, then resistance to prying is improved, but the swinging arc is limited to around 90°

Engineering Contradiction:

Improveresistance to pryingVSAvoidswinging arc range

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The door hinge system is segmented into two independent hinge sets with different axes. The first hinge set provides lateral translation for security, while the second hinge set enables rotation for extended opening. This segmentation allows each hinge to specialize in one movement type while combining to provide both security and extended access capability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The door hinge system performs multiple functions: it provides lateral translation for security overlap, rotation for extended opening arc, and complete clearance of the door jamb zone for full access. The multi-axis design makes the hinge system universal in handling both security requirements and access requirements that single-axis hinges cannot satisfy simultaneously.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A multi-axis door hinge system for a container, the system comprising: a door for enclosing a door frame of the container; a first hinge set, comprising one or more hinge(s) configured along a first hinge axis, mounted to or proximate an external side of the door frame; a second hinge set, comprising one or more hinge(s) configured along a second hinge axis, operatively mounted to an internal side of the door such that the door is rotatable about the second hinge axis, wherein the second hinge set is operatively coupled with the first hinge set so that the second hinge set is rotatable about the first hinge axis, thereby allowing both lateral and rotational movements of the door relative to the door frame.
