Ladder Stabilizing Assembly with Spike and Movable Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Workers often operate ladders without adequate stabilization, risking instability and safety due to the absence of a secondary support at the base of the ladder.
Innovation Solution
A ladder stabilizing assembly comprising a mount, frame, and spike system that attaches to the ladder and extends outward to be driven into the ground, providing additional support and maintaining the ladder's base position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a worker operates a ladder without additional support, then the ease of operation is improved, but the stability of the ladder deteriorates
Solution Approach 1:
The ladder stabilizing assembly enables the ladder to stabilize itself without requiring a second worker. The assembly attaches to the ladder and provides automatic stabilization through its spike mechanism that engages with the ground, allowing the worker to operate the ladder independently while maintaining stability.
Solution Approach 2:
The stabilization function is separated from the ladder structure itself and implemented as a distinct, attachable assembly. This segmentation allows the ladder to maintain its original design for ease of operation while the separate stabilizing assembly provides the necessary stability through its frame and spike components.
2Stability of the object's composition
If a second worker is positioned at the base of the ladder to stabilize it, then the stability is improved, but the device complexity increases
Solution Approach 1:
Instead of requiring a human worker to manually stabilize the ladder, the system employs a self-service mechanical assembly that automatically provides stabilization. The assembly's frame and spike mechanism autonomously engage with the ground to prevent ladder movement, eliminating the need for additional human labor while maintaining stability.
Solution Approach 2:
The stabilizing assembly acts as an intermediary device between the ladder and the ground. Rather than directly having a worker interact with the ladder base, the assembly mediates the stabilization function through its mount attachment to the ladder and spike engagement with the ground, simplifying the overall system while achieving the stability goal.
3Stability of the object's composition
If the frame extends outwardly from the ladder to provide support, then the stability is improved, but the ease of operation deteriorates due to increased space requirements
Solution Approach 1:
The frame is designed to be movable between a stowed position adjacent to the ladder and an extended position outwardly from the ladder. This dynamic configuration allows the frame to provide stability when extended while being compact when stowed, enabling easy storage and transport without compromising the stabilization function when needed.
Solution Approach 2:
When not in use, the frame can be positioned adjacent to and nested against the ladder structure, minimizing the space it occupies. This nesting capability allows the stabilizing components to be stored compactly alongside the ladder, maintaining ease of operation and storage while preserving the ability to extend outwardly when stabilization is required.

AI summary
Systems for stabilizing ladders are provided. A representative system incorporates a ladder stabilizing assembly that includes a mount, a frame and a spike. The mount is configured to attach to a ladder. The frame extends from the mount and is movable between a stowed position, in which the frame is located adjacent the ladder, and an un-stowed position, in which the frame extends outwardly from the ladder. The spike extends from the frame and is operative to be driven into the ground such that, when the frame is in the un-stowed position and the spike is driven into the ground, the ladder stabilizing assembly provides support to the ladder.
