Pickup Rear Door With Vertical Sliding Opening in Tight Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing rear doors of pick-up vehicles often face difficulties in opening due to limited space, which can lead to damage and hinder access to the loading area, especially when parked in tight spaces.
Innovation Solution
A door design featuring a first structure with connecting elements and a second movable structure that can move vertically relative to the first, guided by slides and linked by telescopic cylinders, allowing for two types of openings: a horizontal and a vertical opening, facilitated by actuating elements and a damping device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rear door is opened horizontally in traditional manner, then the door can be fully opened, but the space required behind the vehicle increases and risk of collision with parked vehicles increases
Solution Approach 1:
The patent applies dimensionality change by transitioning from traditional horizontal door opening (2D plane movement) to vertical door opening (3D spatial movement). The door structure includes a first structure mounted on the vehicle and a second structure that moves vertically relative to the first structure, allowing the door to open upward instead of outward, thereby reducing the horizontal space requirement and collision risk with parked vehicles.
2Volume of moving object
If the rear door is made retractable at bumper level, then space utilization is improved, but the door opening accessibility and load access difficulty increase
Solution Approach 1:
The patent divides the door into two separate structures: a first structure that remains mounted on the vehicle and a second structure that moves vertically. This segmentation allows the second structure to be retracted or opened independently, providing both space utilization benefits and maintained accessibility to the load compartment.
3Ease of manufacture
If the door structure is simplified to reduce complexity, then manufacturing cost decreases, but the door opening functionality in confined spaces is compromised
Solution Approach 1:
The patent introduces dynamic movement capability to the door structure by enabling vertical movement of the second structure relative to the first structure. This dynamic feature allows the door to adapt to different parking scenarios and confined spaces while maintaining a relatively simple overall structure that does not require complex mechanical systems.
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 enhances access to the loading area by providing flexible opening options, reducing the risk of damage and improving usability in confined spaces, while ensuring secure locking mechanisms.
Implementation Method 1
The two structures can be linked together by at least one telescopic jack, in particular positioned in a slide of the first structure
Implementation Method 2
The motor vehicle door may comprise a damping device for damping the movement of the second structure relative to the first structure
Implementation Method 3
The first structure may comprise at least two slides, and the vertical movement of the second structure of the door relative to the first structure may be guided by said slides of the first structure
