Vehicle Door Guiding Assembly to Clear Wheel Well Obstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle doors adjacent to wheel wells face limitations in opening and closing due to the obstruction caused by the wheel well, restricting the door's movement and the size of the opening.
Innovation Solution
A vehicle door system with a guiding assembly that constrains the door movement between closed and open positions, allowing it to slide upwards and longitudinally to avoid the wheel well, using a rail and arm assembly to define a travel-path that includes upward and longitudinal vectors during opening, and downward and longitudinal vectors during closing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the door is positioned adjacent to a wheel well, then the door can be located in a compact vehicle design, but the wheel well obstructs the door movement and limits the opening size
Solution Approach 1:
The door movement is transitioned from a conventional horizontal sliding path to a vertical path by incorporating upward motion. The guiding assembly redirects the door's trajectory to move upward alongside the wheel well rather than horizontally across it, effectively utilizing the vertical dimension to resolve the spatial conflict between compact vehicle design and door accessibility.
2Device complexity
If the door is allowed to swing outward conventionally, then the door opening is simple to implement, but the door path is obstructed by the wheel well
Solution Approach 1:
A guiding assembly is introduced as an intermediary mechanism between the door and the wheel well. This guiding assembly, comprising a rail and arm assembly, mediates the door's movement by providing a constrained vertical path that avoids the wheel well obstruction, enabling smooth door operation without direct conflict with the wheel well structure.
3Ease of operation
If the door moves horizontally to open, then the opening mechanism is straightforward, but the door cannot clear the wheel well obstruction
Solution Approach 1:
The door movement is transformed from a static horizontal sliding action to a dynamic vertical motion. The guiding assembly enables the door to adapt its trajectory by moving upward in response to the wheel well obstruction, creating a dynamic travel path that clears the obstacle while maintaining operational simplicity through the rail and arm assembly mechanism.

AI summary
A vehicle comprising: a side wall shaped to define a door opening and a door-exclusion zone, the door-exclusion zone having a maximum height that is higher than a bottom edge of the door opening and lower than a top edge of the door opening; a door having a closed-door position aligned with the door opening and an open-door position higher in its entirety than the door-exclusion zone in its entirely; and a guiding assembly coupled to the door being arranged to constrain the movement of the door between the closed-door position and the open-door position in a travel-path defined to keeping the door of impinging the door-exclusion zone; wherein the door movement constrained to the travel-path includes, in a door-opening mode, an upward vector and a longitudinal vector toward the door-exclusion zone, and in a door-closing mode, a downward vector and a longitudinal vector away from the door-exclusion zone.
