Double Motion Vehicle Door Hinge With Vertical Swivel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing car door hinges, particularly vertically opening ones, face challenges in providing a lightweight and space-optimized design for retrofitting standard factory model vehicles, often resulting in bulky and complex structures that are difficult to use and install effectively.
Innovation Solution
A door hinge system comprising a base member with a primary swivel and shock protrusion, a motorized assembly for vertical door opening, and adjustable components such as a stopper bracket and ball bolt, allowing for customizable installation and operation, including a double motion mechanism for both horizontal and vertical door opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a vertically opening car door hinge is used, then space usage is optimized, but the structure becomes bulky and complex
Solution Approach 1:
The hinge system is divided into separate functional modules: a hinge assembly for vertical opening and a separate door opening assembly for horizontal opening. This segmentation allows each component to be simpler and more specialized, resolving the contradiction between space optimization and structural complexity.
Solution Approach 2:
The hinge system is designed to perform multiple functions: vertical opening via the hinge assembly and horizontal opening via the door opening assembly. This multi-functionality allows a single system to achieve both space optimization and reduced complexity by distributing functions across specialized components.
2Volume of moving object
If a vertically opening car door hinge is used, then space usage is optimized, but ease of installation for retrofitting is reduced
Solution Approach 1:
By segmenting the hinge system into modular assemblies (hinge assembly and door opening assembly), the system becomes easier to manufacture and install. Each module can be produced independently and assembled on-site, facilitating retrofitting while maintaining space optimization.
Solution Approach 2:
The hinge system incorporates adjustable components such as adjustable stoppers and positioning features that allow adaptation to different vehicle door configurations. This dynamic adjustability enhances ease of installation for retrofitting applications while preserving the compact vertical opening design.
3Adaptability or versatility
If a powered assembly is added for vertical door opening, then functionality is enhanced, but device complexity increases
Solution Approach 1:
The powered assembly is integrated with the existing hinge assembly rather than being a completely separate system. The motor and drive mechanism are combined with the hinge components, reducing overall complexity while enhancing functionality to provide both manual and powered vertical door opening capabilities.
Solution Approach 2:
The powered assembly is designed to work in conjunction with the manual hinge operation, creating a multi-functional system that can operate in both powered and manual modes. This universality enhances functionality without proportionally increasing complexity, as the same mechanical components serve dual purposes.

AI summary
A double motion door hinge for a vehicle door includes an upper door connection plate having a second motion assembly pivotally mounted to the upper door connection plate. The axis of rotation of the second motion assembly is perpendicular to the upper door connection plate. A first motion assembly is mounted to the second motion assembly at a first motion hinge. The first motion assembly is adapted to connect to an upper portion of a vehicle door. The lower door connection plate includes a lower door connection plate stopper and a lower shock connection. The lower door connection plate stopper has a lower door double motion stopper surface.
