Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ladder stability solutions, such as telescopic extensions, are costly, fragile, and complex, failing to provide a reliable and simple means to stabilize ladders on uneven ground effectively.
Innovation Solution
A ladder lateral stabilizer accessory featuring a pair of stabilizing members with a movable section and a fixed section, attached via a hinge, allowing the movable section to pivot downward and adjust to uneven ground surfaces without the need for telescoping, using filleted rods and mechanical fasteners for secure attachment, and pivoting pads for ground contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If telescopic extensions are used to stabilize ladders on uneven ground, then adaptability to different ground conditions is improved, but device complexity and cost increase
Solution Approach 1:
The stabilizing member is divided into two distinct sections: a fixed section that attaches to the ladder and a movable section that pivots independently. This segmentation allows each section to perform its specific function - the fixed section provides stable attachment while the movable section adapts to ground variations, eliminating the need for complex telescopic mechanisms.
Solution Approach 2:
The movable section is designed to pivot dynamically around a hinge point, allowing it to automatically adjust its angle and position in response to uneven ground conditions. This dynamic capability provides adaptability without requiring complex telescopic extensions or multiple adjustment mechanisms.
2Reliability
If telescopic extensions are used to stabilize ladders, then stability on uneven ground is improved, but reliability decreases due to fragile components
Solution Approach 1:
The movable section pivots around a fixed hinge point, providing reliable and repeatable motion. This pivot mechanism is inherently more reliable than telescopic extensions because it avoids the fragility of sliding tubes, locking mechanisms, and telescopic joints that are prone to failure.
Solution Approach 2:
The design uses simple, robust geometric forms - specifically triangular configurations formed by the stabilizing members and ground. This triangular geometry provides inherent structural stability and reliability while maintaining adaptability through the pivot joint, avoiding the need for complex telescopic components.
3Stability of the object's composition
If extension members are added to create an A-frame structure, then lateral stability is improved, but device complexity increases
Solution Approach 1:
Each stabilizing member is segmented into fixed and movable sections, allowing the structure to achieve lateral stability through simple pivot motion rather than complex A-frame mechanisms. This segmentation enables the stabilizer to adapt to ground conditions while maintaining structural simplicity.
Solution Approach 2:
Instead of extending members upward to create an A-frame, the movable sections pivot downward to contact the ground. This inverted approach achieves lateral stability by creating a wide base of support through downward-pivoting members rather than upward-extending A-frames, simplifying the overall structure.

AI summary
A ladder lateral stabilizer accessory is provided, which includes a pair of stabilizing members, one for each side of a ladder. Each stabilizing member is attached to the side runners of a ladder by way of filleted rod running through the rungs such that they connect the pair of stabilizing members together from across the width of the ladder. Once installed, the upper part of the pair of stabilizing members which is hingedly attached to the lower part of the stabilizing members. Each movable member of the stabilizing members pivots downwardly so as to make contact with the ground, including uneven ground. When not in use, the upper parts are releasably attached to the ladder runners by way of wing nuts.
