Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drywall mounting systems require multiple personnel to hold and secure large panels, increasing costs and logistical difficulties, and existing supports are cumbersome, difficult to adjust, and require repositioning the panel for adjustments.
Innovation Solution
A drywall support and lift assembly with a mounting portion, a support platform, and a lift mechanism featuring a worm gear and rack and pinion assembly that allows a single user to easily attach, adjust, and secure drywall panels to a wall frame without additional assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional drywall mounting is performed without assistance, then labor costs and logistical difficulty increase, but using multiple personnel improves the ease of mounting large panels
Solution Approach 1:
The support assembly enables a single user to perform the mounting task independently by providing mechanical support and positioning assistance. The device allows the user to hold and position the drywall panel without requiring another person's help, thus transforming a multi-person task into a single-person operation while maintaining ease of mounting.
2Strength
If heavy brace assemblies are used to support drywall sheets, then the support capacity is sufficient, but the device becomes cumbersome and difficult to assemble
Solution Approach 1:
The support assembly is divided into separate modular components including a mounting portion, support platform, and lift mechanism that can be independently assembled. This segmentation allows for easier assembly compared to heavy integrated brace assemblies, while maintaining sufficient support capacity through the coordinated function of these modular parts.
Solution Approach 2:
The lift mechanism with worm gear and rack provides dynamic adjustability, allowing the support platform to be easily raised and lowered to different positions. This dynamic capability enables the device to adapt to different drywall panel sizes and mounting locations without requiring heavy, fixed-brace assemblies, thus reducing cumulative weight and assembly complexity.
3Stability of the object's composition
If fixed brace assemblies are used to support drywall sheets, then the support is stable, but the device is not easily adjustable and requires repositioning the panel for adjustments
Solution Approach 1:
The lift mechanism with worm gear provides dynamic adjustability while maintaining stability. The worm gear's self-locking characteristic ensures the support platform remains stable at any positioned, while allowing easy adjustment by simply rotating the gear. This dynamic-stable combination eliminates the need to reposition the entire device for adjustments, as the platform can be smoothly adjusted to different heights and positions.
Solution Approach 2:
The support assembly allows continuous adjustment of the support platform's position parameters (height, angle, and location) through the worm gear mechanism. This enables the device to adapt to different drywall panel sizes, mounting locations, and positioning requirements while maintaining stable support throughout the adjustment range, eliminating the need to reposition the panel for adjustments.
4Ease of operation
If portable drywall supports are used, then the device is easily relocatable, but the support mechanism becomes less stable and less capable of supporting large panels
Solution Approach 1:
The support assembly uses segmented, modular components that can be easily assembled and disassembled for portability. The mounting portion, support platform, and lift mechanism are separate components that can be quickly put together and taken apart, enabling easy relocation. Despite this portability, the segmented design allows for robust construction of each component to maintain strong support capability for large panels.
Solution Approach 2:
The dynamic lift mechanism with worm gear provides both portability and strong support capability. The mechanism allows the device to be easily assembled and disassembled for relocation, while the worm gear's mechanical advantage and self-locking feature provide stable, strong support when in use. The dynamic nature of the mechanism allows it to adapt between portable and supportive modes seamlessly.

Function Achieved in This Case
Enables a single user to securely mount and adjust drywall panels with precision, reducing labor and logistical challenges, and providing a lightweight, portable solution that maintains panel position without manual effort.
Implementation Method 1
A lift mechanism including a rack is coupled to the support platform. A worm gear is operably coupled to the rack and rotatably coupled to the mounting portion. The lift mechanism is configured to selectively raise and lower the support platform relative to the mounting portion upon rotation of the worm gear.
Implementation Method 2
The lift mechanism includes a rotatable actuator coupled to the support body, a worm gear operably coupled to the rotatable actuator, and a rack and pinion assembly. The rack and pinion assembly is operably coupled to the worm gear and to the support platform. The rack and pinion assembly is configured to selectively raise and lower the support platform relative to the support body upon rotation of the rotatable actuator and the worm gear.
