Concealed Vehicle Door Opening Mechanism with Rotating Cover Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle door handles protrude from the sheet metal plane, leading to increased wind resistance, dust accumulation, and a non-streamlined appearance.
Innovation Solution
A concealed mechanism for opening a vehicle door, featuring a cover plate that rotates on a fixed axle, a transmission mechanism, and an actuator, allowing the door to be opened without protrusions, with a flat surface design that reduces wind resistance and dust accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional protruding handle is used, then the door can be easily opened, but the wind resistance increases and dust accumulates
Solution Approach 1:
The operating mechanism is nested within a recessed cavity in the door panel, with the cover plate fitting into the cavity. When closed, the cover plate is flush with the door surface, creating a streamlined appearance that reduces wind resistance and prevents dust accumulation, while still providing access to the opening mechanism when needed
Solution Approach 2:
The cover plate is designed to be rotatable about a fixed axle, transitioning between a closed flush position and an open position that provides access to the operating mechanism. This dynamic design allows the surface to maintain its streamlined appearance during normal conditions while enabling easy access when the door needs to be opened
2Ease of operation
If a protruding handle is used, then the door opening function is accessible, but the surface appearance becomes non-streamlined
Solution Approach 1:
The entire operating mechanism including the cover plate is nested within a recessed cavity, allowing the external surface to remain flush and streamlined while the operational components are housed within the door panel itself
Solution Approach 2:
The cover plate rotates from a flush closed position to an open position, dynamically changing the surface configuration to provide access to the operating mechanism only when needed, thereby maintaining streamlined appearance during normal operation
3Shape
If a concealed mechanism is used, then the surface is streamlined, but the structure becomes more complex
Solution Approach 1:
The mechanism is segmented into distinct functional components: the cover plate for access, the fixed axle for rotation, the transmission mechanism for force transfer, and the actuator for door opening. This segmentation allows each component to perform its specific function efficiently while maintaining an overall simple and streamlined design
Solution Approach 2:
The transmission mechanism acts as an intermediary between the cover plate rotation and the door opening actuator, transferring and transforming the rotational motion into the appropriate actuation motion, thereby simplifying the overall control architecture
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
The mechanism provides a smooth, aesthetically pleasing surface, reduces wind resistance, and is easy to manufacture and repair, with a simple structure and long service life.
Implementation Method 1
one side edge of the cover plate being mounted on the first fixed rotational axle such that when an external force is applied to the cover plate, the cover plate is rotatable about the first fixed rotational axle to enter the operating cavity
Implementation Method 2
a transmission mechanism, housed in the operating cavity and driven by rotation of the cover plate; when the cover plate rotates inside the operating cavity about the first fixed rotational axle by more than a predetermined angle, the cover plate drives the transmission mechanism such that the transmission mechanism actuates a component for opening the vehicle door

AI summary
A mechanism for opening a vehicle door, comprising: a door opening component for opening the vehicle door, a cover plate, and a first fixed rotational axle. The door opening component is disposed in an operating cavity. The cover plate covers the operating cavity such that the cover plate is concealed in the door. The first fixed rotational axle is mounted adjacent to the operating cavity. A side edge of the cover plate is mounted on the first fixed rotational axle such that when an external force is applied to the cover plate, the cover plate is rotatable about the first fixed rotational axle to enter the operating cavity such that the door opening component is accessible to an operator via the operating cavity to open the vehicle door.
