Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deck construction tools lack an electric drill-powered device that combines functions for removing old deck boards and nails, as well as aligning and holding new deck boards for installation, requiring manual labor and multiple tools.
Innovation Solution
A multi-arm tool powered by an electric drill, incorporating a drill-actuated board lifter, nail puller, and aligning clamp, which removes old deck boards and nails, straightens, aligns, and holds new boards in place for fastening, reducing manual labor and enabling efficient installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual tools (pry bar) are used to remove deck boards, then the device complexity is low, but the productivity and ease of operation are poor requiring significant manual labor
Solution Approach 1:
The patent combines multiple functions (board removal, nail removal, board alignment, and board holding) into a single integrated device. The drill actuates multiple mechanisms simultaneously - the lifter arms for board removal, the nail puller for nail extraction, and the aligning clamp for board positioning - eliminating the need for multiple separate tools and significantly improving productivity.
Solution Approach 2:
The device is designed as a universal tool that performs multiple deck installation and removal tasks. The single drill-powered mechanism can remove boards, extract nails, align new boards, and hold boards in place, making it applicable to various stages of deck construction and renovation work.
2Loss of time
If multiple separate tools are used for deck board removal and installation, then the ease of operation for specific tasks is maintained, but the loss of time increases due to tool switching
Solution Approach 1:
The patent merges the functions of board removal, nail removal, board alignment, and board holding into one integrated device. The drill actuates all these functions through interconnected mechanisms, eliminating the need to switch between multiple tools and significantly reducing installation time.
Solution Approach 2:
The device performs preliminary actions by removing old boards and nails before installing new ones, and simultaneously prepares the installation area by aligning and holding the new boards in place. This sequential preparation within a single device workflow eliminates time losses associated with tool switching.
3Power
If hand-operated nail pullers are used, then the device complexity is low, but the productivity and force application are insufficient
Solution Approach 1:
The patent replaces hand-operated mechanical nail pullers with a drill-powered actuation system. The rotational motion of the drill is converted through gear mechanisms into the linear motion required to extract nails, providing significantly greater force and productivity while maintaining manageable device complexity through standardized mechanical transmissions.
4Manufacturing precision
If manual alignment methods are used for deck boards, then the ease of operation is maintained, but the manufacturing precision and alignment accuracy are insufficient
Solution Approach 1:
The aligning clamp is designed to self-align deck boards through its geometric constraints and spring-loaded adjustment mechanism. The device automatically adjusts to accommodate minor variations in board positioning and maintains precise alignment during installation, eliminating the need for complex external alignment tools while ensuring high alignment accuracy.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tool significantly reduces manual effort, speeds up the deck installation process, allows both hands to be free for fastening, and ensures nails are removed straight for reuse, providing a comprehensive solution for deck board replacement.
Implementation Method 1
a portable drill motor
Implementation Method 2
a threaded shaft extending along the length of the outer structural tube... an inner structural tube or piston riding on the threaded shaft
Implementation Method 3
The actuator mechanism is operated through a gear train to obtain linear motion of the actuator mechanism

AI summary
A multi-function deck tool is powered by a portable electric drill to remove old deck boards and nails and install new boards. Lifting forks remove deck boards. A built-in nail puller removes nails from the deck board supporting beam. An aligning arm attachment straightens and aligns new or loose boards with nailed-in boards and holds them in place, freeing the hands of the installer to nail in the new board.
