Ladder Corner Attachment with 90-Degree Arms for Lateral Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ladders are difficult to safely lean or prop against corners or round features on structures or trees, leading to potential accidents due to dangerous lateral movement.
Innovation Solution
A ladder attachment with first and second arms extending at a 90° angle, secured via bolts to the ladder, allowing it to rest stably on corners or round features, featuring a top and bottom panel connected by a web and mounted via brackets to ladder rungs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional ladder is used against corners or round features, then the ladder can be positioned for use, but the ladder experiences dangerous lateral movement and instability
Solution Approach 1:
The patent introduces an intermediary device (ladder attachment with arms) that mediates between the ladder and the corner/round feature. The attachment includes padded arms that conform to corners and round features, providing a stable interface that prevents lateral movement while being easy to position.
Solution Approach 2:
The patent applies curvature by designing the ladder attachment arms with padded, rounded surfaces that can conform to both corner and round feature geometries. This curved design allows the attachment to adapt to various surface shapes, improving stability without compromising ease of positioning.
2Reliability
If a ladder attachment with multiple arms and mounting components is added, then ladder stability and safety are improved, but the device complexity increases
Solution Approach 1:
The patent divides the ladder attachment into segmented components: a body portion, multiple arms, mounting brackets, and padding elements. This segmentation allows each component to perform its specific function independently while simplifying the overall assembly and installation process.
Solution Approach 2:
The patent merges multiple functions into a single integrated attachment device that combines stability provision, protection of the ladder and structure, and ease of positioning. The attachment unified several safety features into one device, reducing overall system complexity.

AI summary
A ladder attachment may allow a ladder to securely rest on a corner of a structure, structure corners, tree, or the like. The attachment may be attached to the rung of a ladder via several mounting brackets and mounting flanges. The attachment includes first and second arms which may be arranged at about a 90° angle to allow the positioning a ladder on the corner of the structure or oddly shaped structures during use.
