Narrow Base Rolling Ladder Maneuverability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rolling ladders are difficult to maneuver in spaces with limited mobility and narrow aisles due to their large bases, making it challenging to move them between obstacles and utilize space efficiently in environments like warehouses and retail stores.
Innovation Solution
A ladder design featuring a narrow base with an elongated rectangular assembly, connected to the stair section and vertical upright, allowing for a reduced width of no more than six inches, which includes wheels for mobility and a locking mechanism for secure positioning, enabling easier navigation around obstacles and efficient use of space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional rolling ladders are used, then stability and support are provided, but maneuverability and space utilization deteriorate due to large base width
Solution Approach 1:
The base is segmented into a narrow elongated member (6 inches or less) positioned on the centerline, separate from the full ladder width. This segmentation allows the ladder to have a compact base for maneuverability while maintaining full width at the step level for stability and support.
Solution Approach 2:
The base design transitions from a two-dimensional wide base to a three-dimensional elongated narrow base that extends horizontally toward the rear of the ladder. This dimensional change allows the base to provide structural support equivalent to a wide base while occupying minimal floor space for improved maneuverability.
2Ease of operation
If base width is reduced for better maneuverability, then ease of movement improves, but structural stability may worsen
Solution Approach 1:
Different parts of the ladder have different width characteristics: the base is narrow (6 inches or less) for ease of movement, while the step section maintains full width for structural stability and user support. This local quality differentiation allows each part to optimize its function without compromising the whole.
Solution Approach 2:
The base includes an elongated member that extends horizontally toward the rear of the ladder, creating a dynamic structural configuration that provides stability through extended support geometry rather than through increased base width. This dynamic design maintains structural integrity while enabling easy movement.

AI summary
A ladder includes a stair section having a plurality of steps, a vertical upright that connects to a top of the stair section, a base that connects a bottom of the stair section and a bottom of the vertical upright, and one or more wheels connected to the bottom of the vertical upright. The ladder may also include a front locking step and a rear wheel assembly. A narrow base extends between a step of the stair section above a bottom step or locking step and the vertical upright.
