Movable Roof Work Platform Barriers for Safe Vehicle Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work platforms for vehicle roofs, particularly on electrified vehicles, face limitations such as restricted work areas due to railings that hinder free movement, inadequate fall protection, and complex installation/dismantling of safety railings, posing risks to workers from live electrical components and falls.
Innovation Solution
A work platform design featuring movable platform elements that act as fall protection barriers and continue the working plane, controlled by a system ensuring safety from live components and falls, with adjustable dimensions and gap-bridging devices to ensure unrestricted access and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If railings are provided as fall protection and protection against live components, then worker safety is improved, but free movement and workspace on the platform are hindered
Solution Approach 1:
The railing system is designed to be movable rather than fixed. The second platform elements can be transferred between a first position where they form a railing for fall protection and electrical protection, and a second position where they form a continuation of the working plane, enabling unrestricted access to the vehicle roof.
2Reliability
If railings are provided along longitudinal sides, then fall protection is improved, but the working area is limited
Solution Approach 1:
The second platform elements dynamically change configuration based on operational needs. When in the first position, they provide fall protection along the longitudinal sides. When transferred to the second position, they extend the working plane to increase the available working area for vehicle roof maintenance.
3Adaptability or versatility
If removable railings are provided, then adaptability is improved, but dismantling and installation becomes complex and time-consuming
Solution Approach 1:
The system uses a controlled transfer mechanism that automatically moves the second platform elements between positions based on detected vehicle parameters, eliminating the need for manual dismantling and installation of removable railings while maintaining adaptability to different vehicle configurations.
Solution Approach 2:
Sensors detect vehicle dimensions and configurations, and this information feeds back to the control system which automatically adjusts the position of the second platform elements, enabling rapid adaptation without manual intervention.
4Stability of the object's composition
If fixed platform elements are used, then structural stability is improved, but adaptability to different vehicle dimensions is reduced
Solution Approach 1:
The platform combines fixed first platform elements that provide structural stability with movable second platform elements that can be transferred between positions. This hybrid design maintains platform stability while enabling adaptation to different vehicle dimensions through the controlled movement of the second elements.
Solution Approach 2:
Sensors detect vehicle dimensions and feed this information to the control system, which automatically adjusts the position of the second platform elements to match the specific vehicle configuration, enabling adaptation while maintaining structural stability.

AI summary
The invention relates to a work platform (31) for work on a roof area of an electrified vehicle (12) comprising a platform (36). The platform (36) has first platform elements (37, 57, 77) that form a working plane (34) and each have a longitudinal extension with two opposing longitudinal sides (38, 39, 58, 59, 78, 79), and several second platform elements (46 to 54, 66 to 74) that are arranged along at least one of the longitudinal sides (39, 58, 59, 78) of the first platform elements (37, 57, 77) and are movable between two positions relative to the first platform elements (37, 57, 77). The second platform elements (46 to 54, 66 to 74) form a fall protection barrier in a first position and a continuation of the working level (34) of the first platform elements (37, 57, 77) in a second position. The invention further relates to a maintenance device with at least one such work platform (31).
