Automated Lifting Device for Building Materials on Elevated Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for delivering building materials to elevated surfaces, such as roofs, require manual labor and are limited by the type of roof pitch and surface material, lacking a solution for automated and versatile loading solutions.
Innovation Solution
A system comprising a lifting device with a descending fork frame and portable supports that can transport and hold loads on various target surfaces, including pitched roofs, without the need for manual labor, using a platform with fork pockets for secure attachment and spacing to maintain load stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual methods are used to place building materials on roofs, then personnel can directly position materials, but safety risks increase and labor intensity is high
Solution Approach 1:
The system enables self-service by using automated lifting and positioning mechanisms that operate without human intervention on the roof. The portable support structure automatically secures materials once delivered, eliminating the need for workers to manually position and secure heavy building materials at heights.
Solution Approach 2:
The patent introduces an intermediary automated delivery system that acts as a mediator between ground-level material storage and roof-level installation points. This intermediary system includes lifting devices and portable support structures that transfer materials safely without requiring personnel to be on the roof during the hazardous handling process.
2Adaptability or versatility
If table top devices are used to hold building materials on roofs, then materials can be held in place, but the devices are limited to specific roof types and pitches
Solution Approach 1:
The portable support structure incorporates adjustable and adaptable components that can dynamically configure to match different roof geometries. The structure includes adjustable legs, extendable support members, and configurable attachment mechanisms that can accommodate varying roof pitches, slopes, and surface types while maintaining secure material holding capability.
Solution Approach 2:
The patent designs a universal portable support structure that can function across multiple roof types and configurations. The structure serves multiple functions including material support, positioning, and securing, while adapting to different roof geometries through adjustable components, making it versatile for various construction scenarios without compromising holding reliability.
3Productivity
If automated lifting devices are used to transport materials, then labor requirements are reduced, but device complexity increases
Solution Approach 1:
The automated material delivery system is segmented into modular functional units including lifting mechanisms, portable support structures, and attachment devices. Each module performs a specific function and can be independently controlled or replaced, reducing overall system complexity while maintaining high productivity through coordinated operation of these simplified modular components.
