Sectional Vehicle Door With Movable Window for Wide Side Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle doors with complex geometries face challenges such as increased width on opening, manual slamming causing overpressure, need for electricity inside the door, and limited design freedom due to rigid windows and sliding rails.
Innovation Solution
A sectional vehicle door with a top frame pivoting on the roof and a bottom door leaf pivoting on a top frame, allowing minimal width expansion on opening, manual or automated closure without slamming, and movable windows translating outward for improved accessibility and design flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single-piece door is used to close a large opening, then accessibility is improved, but the door width increases significantly when open
Solution Approach 1:
The door is divided into two distinct parts: a fixed top frame that remains attached to the vehicle body, and a movable bottom door leaf that can be opened independently. This segmentation allows the bottom leaf to provide accessibility while the top frame maintains a compact profile, resolving the contradiction between ease of operation and door width.
2Speed
If manual slamming closure is used, then closure speed is improved, but overpressure is generated in the interior
Solution Approach 1:
A cam mechanism acts as an intermediary between the door leaf and the striker. The cam's curved surface guides the door closure, allowing rapid closing while controlling the impact point and direction. This intermediary mechanism enables fast closure without generating harmful overpressure in the vehicle interior.
3Reliability
If motorized striker and sliding bolt are used for locking, then locking reliability is improved, but electricity must be brought into the door
Solution Approach 1:
The electrical motorized locking system is replaced with a purely mechanical cam-and-striker mechanism. The cam, when rotated manually or automatically, mechanically engages the striker to lock the door. This substitution eliminates the need for electricity infrastructure inside the door while maintaining reliable locking through mechanical advantage.
4Adaptability or versatility
If windows are placed in the upper part of the door, then design flexibility is improved, but space is consumed widthwise or opening is limited
Solution Approach 1:
The window is repositioned from the traditional upper horizontal placement to the lower vertical placement within the door leaf. This dimensional change allows the window to open vertically downward rather than horizontally outward, providing design flexibility while minimizing widthwise space consumption and maximizing opening area.

AI summary
The invention relates to a sectional door of a vehicle opening as close as possible to the body of said vehicle, having cam strikers for closing, locking and opening same, having actuators for opening same and having a movable window capable of separating from said body and translating horizontally along said door. These elements are implemented on a door having surfaces with a complex geometry, thus providing a one-piece body having surfaces with a complex geometry, with a single large opening on the side for accessing the front seats and the rear seats, and a single large door for closing said opening.
