External Sliding Door Layout for Full-Height Vehicle Door Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle door designs restrict the clear height of the door portal due to the placement of support guides, limiting the available space within the vehicle.
Innovation Solution
A vehicle door device featuring an outer sliding door with an electro-mechanical drive system, door guide, and locking mechanism entirely arranged on the outer vehicle wall, utilizing magnetic interaction between stator and rotor modules for operation, allowing for increased space utilization and simplified assembly by eliminating mechanical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If support guides are placed in the upper part of the door portal opening, then the door device can be supported and guided, but the clear height of the door portal is limited
Solution Approach 1:
The support and guidance functions are extracted from the door portal opening and relocated to the outer wall of the vehicle. The door guide device is mounted on the outer wall, completely outside the door portal opening, thereby eliminating the space occupation within the portal and maximizing the clear height while maintaining reliable door support and guidance.
2Stability of the object's composition
If mechanical connections between external and internal components are used, then structural stability is achieved, but installation complexity and space requirements increase
Solution Approach 1:
The mechanical connection system is replaced with a magnetic field-based electromechanical drive device. The drive device includes a stator module with magnet coils and a rotor module with permanent magnets that interact magnetically to drive the door, eliminating the need for complex mechanical connections between external and internal components while maintaining operational stability.
3Volume of moving object
If door mechanism components are mounted inside the vehicle body, then space utilization is improved, but available space for other systems is reduced
Solution Approach 1:
The door mechanism components, including the drive device and guide device, are extracted from the internal vehicle body space and mounted on the outer wall. This external mounting arrangement completely eliminates the space occupation within the vehicle body, maximizing the available internal volume for passenger space and other essential systems while maintaining effective door operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design maximizes available space within the vehicle by eliminating internal mechanical connections and allowing for the installation of other essential systems, while enabling efficient operation of the door mechanism with reduced electrical dependency through an integrated emergency unlocking system.
Implementation Method 1
a magnetic interaction arises between the at least one stator module and the at least one rotor module when the magnet coils are energized and, as a result of the magnetic interaction, a magnetic force is exerted as a driving force on the at least one outer door
