Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ladder support structures are large, separate components that hinder ladder mode changes and require removal for different uses, lacking a multifunctional, adjustable solution.
Innovation Solution
A permanent, adjustable ladder support device with arm structures and connectors that can be extended, angled, and locked in various positions, providing stability and functionality without hindering ladder modes, and featuring a locking mechanism and fastener holes for additional support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate support structures are attached to the ladder, then the ladder gains additional support functionalities, but the device complexity increases and the ladder's mode switching capability is hindered
Solution Approach 1:
The patent combines multiple support structures (roof standoffs, wall standoffs, stabilizers) into a single integrated attachment system that can be mounted to the ladder. This merging approach provides diverse support functionalities while reducing the number of separate components needed, thereby addressing the contradiction between versatility and device complexity
Solution Approach 2:
The integrated support attachment is designed to perform multiple functions including roof standoff, wall standoff, and stabilizer roles. This multi-functionality allows a single device to replace multiple separate support structures, enhancing adaptability while maintaining relatively simple device complexity
2Adaptability or versatility
If separate support structures are used, then the ladder gains support features, but the ease of operation deteriorates due to removal and reattachment requirements
Solution Approach 1:
By merging multiple support features into a single integrated attachment, the system eliminates the need to separately attach and detach multiple individual support structures. This consolidation improves ease of operation while maintaining the versatility of support features
3Adaptability or versatility
If inbuilt attachment is provided, then the ladder maintains functionality across different modes, but the device complexity increases
Solution Approach 1:
The inbuilt attachment is designed with universal functionality to serve multiple support roles (roof standoff, wall standoff, stabilizer) across different ladder modes. This multi-functional design ensures the ladder maintains functionality across modes while the integrated nature of the attachment keeps the overall device complexity manageable

AI summary
The multifunctional ladder support device is intended to provide users with an adjustable accessory for different kinds of ladders. More specifically, the device is a permanent attachment to a ladder that enables users to use the attachment as a roof standoff, wall standoff, ladder stabilizer, etc. To accomplish this, the device includes a plurality of arm structures attached to the plurality of side rails of the ladder. Each of the arm structures have multiple pieces and connectors that help to extend the arm structures in different directions and angles, to achieve the intended functionalities. Further, the device may be stowed in a retracted mode, without hindering any functionalities of the ladder. Furthermore, the arm structures have holes to thread through external fasteners, thereby providing additional support and stability features to the ladder system. Thus, the device is a simple and efficient accessory and safety attachment for ladders.
