Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional panel lifting devices are inefficient in providing a mechanical advantage for lifting panels like drywall or plywood, and they lack a design that ensures stable support and easy maneuverability during the lifting process.
Innovation Solution
A panel lifting device comprising a rigid beam with a longitudinal load and effort portion, a pivotable fulcrum, and a roller, where the beam is formed as a single, integrally constructed component from metal, offering a mechanical advantage and enhanced stability through a tapered foot platform and wings to restrict roller movement, allowing for efficient panel lifting and positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a conventional panel lifting device is used, then the device can lift panels, but it provides insufficient mechanical advantage and lacks stable support
Solution Approach 1:
The beam is divided into distinct functional segments: a load portion extending proximally from the fulcrum and an effort portion extending distally from the fulcrum. This segmentation allows each portion to be optimized for its specific function - the load portion for supporting panel weight and the effort portion for providing mechanical advantage through user input force.
Solution Approach 2:
The foot platform incorporates a tapered width feature that transitions from the proximal end to the distal end, adding a dimensional variation that provides stable support for the user's foot while maintaining the lever mechanism's effectiveness. This dimensional change enhances stability without compromising the mechanical advantage.
2Ease of manufacture
If the beam is made as a single integrally formed component, then manufacturing is simplified and strength is improved, but the design becomes less adaptable to different panel sizes
Solution Approach 1:
The single integrally formed beam design serves multiple functions: it provides structural strength, acts as a lever mechanism with defined load and effort portions, offers stable foot platform support through its tapered geometry, and accommodates different panel sizes through its adjustable fulcrum positioning capability. This multi-functionality eliminates the need for separate components while maintaining versatility.
3Force
If the effort portion has greater mass than the load portion, then the lever provides better mechanical advantage, but the device becomes harder to maneuver
Solution Approach 1:
The beam exhibits non-uniform mass distribution with the effort portion having greater mass than the load portion. This local quality variation is strategically positioned to provide mechanical advantage during the lifting phase, while the overall balanced design maintains ease of maneuverability during positioning and setup operations.

AI summary
A panel lifting device includes a rigid beam and a roller coupled to the beam. The panel lifting device is pivotable at a fulcrum. A beam body includes an upper foot platform. The upper foot platform may have a width gradually increasing from the proximal end of the beam body toward the distal end of the beam body. The roller may be coupled to the beam by opposite tabs extending inward from opposite side walls and received in open ends of the roller. The opposite tabs may be integrally formed with the side walls. A rigid wing may extend downward from the upper foot platform adjacent the roller and opposing an outer circumferential surface of the roller. The rigid beam may be a single, one-piece, integrally formed component formed from a single sheet of metal.
