Vehicle Tread Plate Row Profile for Easier Dirt Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tread systems with anti-slip profiles, such as checker plates, face challenges in efficient cleaning due to dirt particles getting trapped between profile elements, which can lead to slipping hazards, especially in wet conditions.
Innovation Solution
A tread system with profile elements arranged in rows, where each element has a greater length along a longitudinal axis than a transverse axis, facilitating directional cleaning by brushes that sweep along the rows, and optionally having brush members to clean both the tread surface and profile element surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If checker plates with profile elements are used to provide anti-slip effect, then passenger safety is improved, but cleaning efficiency deteriorates due to dirt particles trapped between profile elements
Solution Approach 1:
The profile elements are segmented into discrete rows with controlled spacing, creating defined channels between rows that facilitate dirt particle removal while maintaining anti-slip functionality on the tread surface
Solution Approach 2:
Different regions of the tread plate have different properties: the profile element surfaces provide anti-slip quality where passengers step, while the spaces between rows provide cleaning accessibility for brush members to remove dirt particles
2Reliability
If profile elements are arranged in checkered pattern, then anti-slip performance is improved, but dirt removal becomes difficult
Solution Approach 1:
The checkered pattern is segmented into distinct rows with uniform spacing, transforming the continuous checkered structure into discrete parallel elements that create accessible channels for dirt removal while preserving the anti-slip characteristic
Solution Approach 2:
The profile elements are arranged in a directional row pattern rather than a symmetric checkered pattern, introducing a primary directionality that facilitates linear brush movement for cleaning while maintaining sufficient friction surfaces for anti-slip performance

AI summary
A tread system for a vehicle includes a tread plate, which is movable, underneath a tread strip edge of the vehicle, from a retracted position in the direction towards a deployed position and vice versa along a deployment axis extending perpendicularly to the tread strip edge. The tread plate has a tread surface capable of bearing tread loads, on which an anti-slip profile is formed, wherein the anti-slip profile has profile elements, wherein each profile element is raised relative to a tread surface base and has a greater length along a respective longitudinal profile element axis than along a transverse profile element axis that extends perpendicularly to the longitudinal profile element axis and parallel to the tread surface base.In order for the tread plate to be capable of being cleaned in a simplified manner and with improved efficiency, it is proposed that the profile elements are arranged in rows.
