Vehicle Door Assembly Segmentation for Compact Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle door assemblies do not efficiently manage the width extension when transitioning between closed and open positions, limiting access to passenger compartments, especially in tighter spaces.
Innovation Solution
A vehicle door assembly design where the forward door panel is hingedly connected to the rear door panel, allowing both panels to pivot approximately 180 degrees, with a locking mechanism to secure the forward door to the vehicle body, reducing the overall width extension when opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the door assembly is opened to provide access to passenger compartments, then accessibility is improved, but the width extension increases
Solution Approach 1:
The door assembly is divided into two separate panels: a forward door panel and a rear door panel. The forward panel is hingedly connected to the vehicle body structure, while the rear panel is hingedly connected to the forward panel. This segmentation allows the rear panel to be opened independently to access passenger compartments without requiring the entire door assembly to extend fully outward, thereby improving accessibility while reducing the overall width extension.
2Stability of the object's composition
If the forward door panel is lockingly connected to the vehicle body structure, then structural stability is improved, but device complexity increases
Solution Approach 1:
The locking mechanism for the forward door panel is integrated with the existing vehicle body structure rather than being a separate, complex assembly. The lockable connection combines the forward panel's hinged movement with a straightforward locking feature that engages with the vehicle body structure, providing structural stability while avoiding unnecessary complexity in the overall door assembly mechanism.
