Remote-Controlled Shingle Installation Jack for Roof Levels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current method of manually re-mounting walk boards at different roof levels for shingle installation or repair is inefficient, time-consuming, and poses safety risks due to the need for repeated securement, especially on slanted roofs.
Innovation Solution
A remote-controlled shingle installation jack device that allows for the mechanical raising and lowering of a walk board between roof levels, eliminating the need for continuous re-mounting by using a frame with a pulley, winch motor, and adjustable cable system, enabling continuous movement up and down the roof.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If walk boards are manually re-mounted at different roof levels, then workers can access various roof levels for shingle installation, but the process becomes time-consuming and labor-intensive
Solution Approach 1:
The patent applies the dynamics principle by transforming the static walk board into a movable one through the jack device. The walk board is no longer fixed at a single level but can be dynamically adjusted to different roof levels using the winch motor and cable system, eliminating the need for repeated manual re-mounting
Solution Approach 2:
The jack device serves as an intermediary mechanism between the walk board and the roof structure. Instead of directly re-mounting the walk board at different levels, the jack device mediates this process by providing mechanical lifting and positioning capabilities, allowing the walk board to be raised and lowered as needed
2Reliability
If walk boards are repeatedly mounted and dismounted, then workers can safely access different roof levels, but safety risks increase due to repeated securement requirements
Solution Approach 1:
The jack device enables self-service by allowing workers to independently adjust the walk board position to different roof levels without requiring assistance for mounting and dismounting operations. The remote control capability further enhances this by allowing one worker to operate the device while another safely positions the walk board
Solution Approach 2:
The patent replaces the manual mechanical system of mounting and dismounting walk boards with a motorized winch system. Instead of manually securing and unsecuring the walk board at different levels, the winch motor mechanically lifts and lowers it, reducing the complexity and safety risks associated with repeated manual securement
3Device complexity
If manual mounting methods are used, then simple equipment is required, but labor intensity and time consumption increase significantly
Solution Approach 1:
The patent replaces simple manual mounting equipment with a motorized winch system that provides mechanical advantage. The winch motor, cable, and pulley system substitute for manual labor, enabling one or two workers to efficiently position the walk board at any roof level without the high labor intensity associated with manual methods
Solution Approach 2:
The invention changes the key parameter of position accessibility by enabling the walk board to reach any roof level rather than being limited to fixed mounting points. The adjustable cable length and winch motor allow continuous vertical positioning, transforming the discrete step-by-step access into a continuous range of accessible heights

Function Achieved in This Case
Facilitates efficient and safe shingle installation or repair across various roof levels without re-mounting walk boards, reducing labor and enhancing safety by allowing continuous movement and secure positioning of the walk board at any desired roof height.
Implementation Method 1
a spring spanning from the top member of the frame to the upper surface of the mounting assembly
Implementation Method 2
a bottom member for anchoring a pulley

AI summary
The shingle installation jack devices may be mounted once at a first roof level, providing support for the walk board. When installation or repair of the shingles is complete at the first level of the roof, the shingle installation jack devices may be operated in tandem to raise the level of the walk board to a second level of the roof. Shingle installation and/or repair may then be carried out at this second roof level without the need to re-mount the walk board supports at the second level. The shingle installation jack devices may also be run in reverse to lower the walk boards. The shingle installation device includes a frame and utilizes a winch motor to adjust the effective length of a cable and thus adjustably raise or lower the walk boards to any desired roof level.
