Dual-Plane Latching Rod for Vehicle Door Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door stop technologies for motor vehicles lack precision and comfort in positioning the vehicle door, as they fail to provide a consistent holding force and desired action characteristic during opening and closing.
Innovation Solution
A door stop design featuring a latching rod guided in two independent planes of action, with horizontally and vertically arranged latching depressions and flattened portions, engaging with spring elements that act in both vertical and horizontal directions, allowing for precise positioning and enhanced latching functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single-plane latching mechanism is used, then the device complexity is reduced, but the positioning precision and holding force are insufficient
Solution Approach 1:
The patent transitions from a single-plane latching mechanism to a dual-plane latching mechanism. The first plane contains latching depressions and flattened portions on the upper and lower surfaces of the latching rod, while the second plane contains latching depressions and flattened portions on the side surfaces. This dimensional expansion enables independent vertical and horizontal latching actions, significantly improving door positioning precision and holding force.
Solution Approach 2:
The latching mechanism is segmented into two independent planes of action. The first plane handles vertical latching with spring elements acting in the vertical direction, while the second plane handles horizontal latching with spring elements acting in the horizontal direction. This segmentation allows each plane to be optimized independently for its specific latching function, achieving precise positioning without excessive overall complexity.
2Force
If spring elements are arranged in a single plane, then the device complexity is reduced, but the latching function and holding force are insufficient
Solution Approach 1:
The spring elements are arranged in two independent planes rather than a single plane. Spring elements in the first plane act vertically on the latching rod, while spring elements in the second plane act horizontally on the latching rod. This spatial arrangement in multiple dimensions enables the mechanism to generate holding force in both vertical and horizontal directions, significantly enhancing the overall latching function and holding force.
3Ease of operation
If a simple latching mechanism is used, then the ease of manufacture is improved, but the action characteristic and user comfort are insufficient
Solution Approach 1:
The dual-plane latching mechanism provides independent vertical and horizontal latching actions, creating a more sophisticated action characteristic that enhances user comfort during door operation. The vertically arranged spring elements and horizontally arranged spring elements work independently to provide smooth, controlled latching motion in multiple directions, improving the overall user experience despite increased manufacturing complexity.
