Alternating Width Parking Space Markings for Driver Door Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-storey car parks with standard-sized parking spaces are insufficient for modern vehicles, leading to difficulties in opening doors and increased risk of parking damage due to restricted space, particularly affecting two-door cars and individuals with mobility issues.
Innovation Solution
The introduction of laterally delimiting markings and built-in parts, with alternating wide and narrow sections, to create a protective path for the driver's door while maintaining small space for the passenger door, allowing for comfortable vehicle exit and improved accessibility, along with directional arrows to guide proper parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If standard-sized parking spaces (2.3-2.5m width) are used, then space utilization is maximized, but driver accessibility and door opening space are insufficient
Solution Approach 1:
The parking space boundary is segmented into two distinct zones: a first section with a first width (e.g., 2.3-2.5m) and a second section with a second width (e.g., 3.0-3.5m). This segmentation allows the driver's door to be positioned in the wider second section, providing adequate opening space, while the narrower first section maintains efficient space utilization for vehicle parking.
2Ease of operation
If parking space width is increased to accommodate modern vehicles, then door opening space is improved, but the number of parking spaces per area is reduced
Solution Approach 1:
Different sections of the parking space boundary are assigned different width characteristics. The first section maintains a narrower width optimized for space efficiency, while the second section provides a wider width specifically at the driver's door location to ensure adequate opening space. This local differentiation resolves the contradiction between overall space utilization and local accessibility.
3Productivity
If uniform narrow parking spaces are provided, then maximum parking capacity is achieved, but parking damage risk increases due to restricted door opening
Solution Approach 1:
By segmenting the parking space boundary into narrow and wide sections, the invention allows drivers to open their doors into the wider second section without encroaching on adjacent parking spaces. This reduces the risk of door-related parking damage while maintaining high overall parking capacity through the efficient use of narrow sections.
4Ease of operation
If laterally delimiting markings and built-in parts are introduced with alternating wide and narrow sections, then driver accessibility is improved, but device complexity increases
Solution Approach 1:
The invention introduces local quality variations in the parking space boundary configuration, creating alternating wide and narrow sections. This approach improves driver accessibility at specific locations (driver's door area) while maintaining simple, standardized configurations for the majority of the parking space, thus balancing accessibility improvement with minimal increase in overall system complexity.

AI summary
The invention is an arrangement for orienting multi-track vehicles in the direction of travel in car parks or in garages, wherein arrows which show the direction of travel and floor markings which indicate the parking spaces are provided on the floor of the parking area and/or on the walls of the garage as well as on free-standing indicator boards. Different markings and installed components (2), (3) which form lateral boundaries are provided between the parking areas characterized above, in order to achieve corresponding economy of space and also to facilitate exiting from vehicles, wherein a wide footpath (2), characterized by marking or an installed component and a narrow boundary device, characterized by an installed component (3) or a marking, are provided alternately, wherein they each respectively serve as a parking lane boundary.
