Carrier Device for Roof Panel De-stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Arranging roof covering panels on a roof is a heavy and labor-intensive task due to the weight and size of the panels, which requires lifting and precise placement.
Innovation Solution
A carrier device with pairs of co-acting carrier elements and drive means that allows for efficient transportation and upward displacement of a stack of panels, enabling individual panels to be presented at a suitable height and location for easy placement, using either manual or electric drive mechanisms and featuring adjustable carrier elements and spacers for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If roof covering panels are manually lifted and arranged on a roof, then the panels can be placed on the roof, but the work is heavy and labor-intensive due to the weight of the panels
Solution Approach 1:
The stack of panels is segmented into individual panels that can be presented one at a time by the carrier device. Each panel is separately carried by carrier elements that can be individually controlled, allowing workers to handle one panel at a time rather than managing the entire stack, thereby reducing the physical effort required.
Solution Approach 2:
The carrier device automatically presents panels to the roof level and positioning system, reducing the need for manual lifting. The system serves itself by mechanically delivering panels to the correct location and orientation, minimizing human physical intervention in the heavy lifting process.
2Productivity
If panels are transported as a complete stack to the roof, then transportation efficiency is improved, but individual panel access and placement become more difficult
Solution Approach 1:
The carrier device incorporates dynamically adjustable carrier elements that can move independently to present individual panels from the stack. The carrier elements can be positioned at different heights and locations, allowing flexible access to any panel in the stack while maintaining efficient transportation of the entire stack to the roof.
Solution Approach 2:
The system adds a vertical dimension to panel access by using carrier elements that can move up and down along the stack height. This allows individual panels to be extracted from any position in the vertical stack without requiring horizontal manipulation of the entire stack, improving both transportation efficiency and individual panel accessibility.
3Adaptability or versatility
If carrier elements are fixed in position, then the device structure is simpler, but individual panel presentation at varying heights and locations is not possible
Solution Approach 1:
The carrier elements are made dynamically adjustable rather than fixed, allowing them to move to different positions along the stack. This enables the same carrier device to adapt to different panel extraction requirements while maintaining a relatively simple overall structure through modular design.
Solution Approach 2:
The carrier elements are designed with multi-functionality, serving both as structural support members and as adjustable positioning mechanisms. Each carrier element can function as a simple support when not in use and as an active positioning device when needed, reducing the need for separate components and minimizing overall device complexity.
4Productivity
If all carrier elements are driven simultaneously, then the mechanism is simpler to control, but individual panel extraction speed and precision are reduced
Solution Approach 1:
The drive mechanism is designed to be dynamically controllable, allowing selective activation of individual carrier element drives based on which panel needs to be extracted. This enables rapid panel extraction by activating only the necessary drives, improving productivity without requiring all drives to operate simultaneously, thus managing complexity effectively.
