Ladder Stabilization Device with Flexible Ribbed Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ladder stabilization devices fail to adapt to irregular roof surfaces and require complex mounting systems, potentially damaging fragile roof materials and lacking in stability during user ascent and descent.
Innovation Solution
A dual stabilization system with upper and lower mechanisms that pivot and adjust to prevent lateral and backward slippage, using flexible ribbed materials for non-slip contact and adjustable latches to secure the ladder without contacting the gutter, compatible with various ladder types and allowing quick assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid stabilization device is used, then stability is improved, but adaptability to irregular roof surfaces deteriorates
Solution Approach 1:
The patent employs flexible ribbed stabilization elements that can conform to irregular roof surfaces while maintaining gripping force. The ribbed structure provides flexibility to adapt to surface variations while the interlocking mechanism ensures stable fixation of the ladder.
Solution Approach 2:
The stabilization device incorporates movable and adjustable components that can dynamically adapt to different roof geometries. The device transitions from a static rigid structure to a dynamic system that can be positioned and shaped according to the specific roof configuration.
2Stability of the object's composition
If a complex remote locking system is used, then stability is improved, but device complexity increases
Solution Approach 1:
The patent combines the stabilization and locking functions into a single integrated device mounted at the top of the ladder. This merges multiple functions (stabilization, locking, adaptation) into one compact system, eliminating the need for separate mounting systems at different locations.
Solution Approach 2:
The device incorporates self-locking mechanisms that automatically engage and secure the ladder to the roof without requiring complex remote locking systems. The design allows the structure to lock itself into position through its own weight and the inherent mechanics of the ribbed engagement system.
3Stability of the object's composition
If stabilization arms are positioned close to the gutter, then stability is improved, but harmful factors increase due to potential contact with fragile roof materials
Solution Approach 1:
The patent introduces flexible ribbed stabilization elements as intermediaries between the rigid ladder structure and the fragile roof surface. These ribbed elements act as a protective mediator that distributes contact forces and prevents direct contact between hard stabilization arms and vulnerable roof materials like zinc or plastic gutters.
Solution Approach 2:
The flexible ribbed structure serves as a protective interface that conforms to the roof surface without exerting concentrated loads on fragile materials. The flexibility allows the stabilization device to maintain contact and stability while protecting the roof from damage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures secure and damage-free ladder placement on roofs with improved stability and ease of use, protecting roof materials and accommodating different roof shapes and ladder designs.
Implementation Method 1
flexible ribbed material (8) making it possible to protect the roofing materials and by its friction, limit the lateral movements of the device relative to the roof
Implementation Method 2
the flexible cylindrical buffer (18) will therefore come into contact with the arm (12) of the lower stabilization device (3), cause the latter to pivot around the axis (19) and allow the flexible ribbed part (14) to come into contact with the under the roof (11) or one of its rafters (10)
Implementation Method 3
by its friction, limit the lateral movements of the device relative to the roof

AI summary
The device has lower stabilization devices (3, 3') actuated by control units (4, 4') by an assembly composed of control rods (15, 15') and a flexible cylindrical baffle plate (18). The plate is in contact with an arm (12) when an user triggers the control unit towards outside for causing rotation of the control rods and the control units around an axle (19) so as to allow the stabilization devices to pivot around the axle and to have contact with a roof or one of studs to adapt to different thicknesses of the roof.
