Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deck board plugs often fail to match the aesthetic appearance of the surrounding deck boards due to differences in material batches, leading to unsightly and aesthetically displeasing installations, and can trap moisture, causing damage and promoting algae growth.
Innovation Solution
A plug cutting tool that produces plugs with an aesthetic exterior surface matching the donor board, featuring a cutting edge that rotates to create a plug face, sidewall, and bottom, with a movable cutting edge to taper the plug, allowing it to fit seamlessly into recipient board holes, and a stabilizer to prevent tool wobbling during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pre-manufactured plugs are used to fill screw holes, then the holes can be plugged efficiently, but the plugs often do not match the aesthetic appearance of the surrounding deck boards due to different material batches
Solution Approach 1:
The invention performs preliminary action by cutting the plug from the actual deck board before installation. The cutting tool removes a cylindrical portion of the board that contains the screw hole, creating a plug that is guaranteed to match the board's grain, color, and texture. This preliminary cutting action ensures aesthetic continuity while maintaining efficient installation.
Solution Approach 2:
The invention creates a perfect copy of the board material by cutting the plug directly from the board itself. The plug is an exact replica of the surrounding material in terms of grain pattern, color variation, and texture, ensuring seamless visual integration. This copying approach eliminates the mismatch problem inherent in pre-manufactured plugs from different batches.
2Ease of manufacture
If conventional plugging methods are used, then holes can be filled, but moisture and debris can remain trapped in the holes causing damage and algae growth
Solution Approach 1:
The cutting tool performs preliminary cleaning action by removing debris and moisture from the screw hole during the plug cutting process. As the cylindrical portion is cut from the board, the hole is cleared of contaminants. Additionally, the tapered configuration allows the plug to be driven into the hole, compressing any remaining moisture and debris outward, preventing trapped moisture issues.
Solution Approach 2:
The invention changes the geometric parameters of the plug by providing a tapered configuration rather than a uniform cylindrical shape. The plug has a larger diameter at the top and a smaller diameter at the bottom, creating a wedge effect that facilitates insertion and ensures proper seating. This parameter change allows the plug to be driven into the hole with controlled force, expelling moisture and debris effectively.
3Ease of manufacture
If plugs from different material batches are used, then plug production is simplified, but the plugs appear as an obviously different shade or hue contrasting the surrounding board
Solution Approach 1:
The invention eliminates the color and grain matching problem by performing preliminary action - cutting the plug from the actual board being worked on. This ensures the plug material is identical to the surrounding board material in terms of batch, color, grain pattern, and texture. The preliminary cutting action from the source board guarantees aesthetic continuity without requiring separate matching processes.
Solution Approach 2:
The invention applies local quality by creating a plug with the exact same material properties as the specific location where it will be installed. Rather than using generic plugs from bulk production, the plug is locally sourced from the actual board, ensuring that the grain direction, color variation, and texture match the immediate surrounding area perfectly.
4Manufacturing precision
If a rotating cutting tool is used to create plugs, then plugs with aesthetic exterior surfaces can be produced, but the tool may wobble during operation reducing precision
Solution Approach 1:
The invention introduces an intermediary stabilizing component that contacts the board surface to prevent tool wobble. The stabilizer element acts as a mediator between the rotating cutting tool and the workpiece, providing additional support and constraint. This intermediary component ensures the tool remains stable and accurate during operation while allowing the cutting edge to produce a high-quality aesthetic surface on the plug.
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 efficiently creates plugs that closely match the deck boards, enhancing the deck's appearance and reducing moisture retention, thereby minimizing damage and maintenance issues.
Implementation Method 1
a cutting edge that rotates about the tool axis and advances the tool into a donor board face to produce a plug having a plug face including the aesthetic exterior surface
Implementation Method 2
another cutting edge that is selectively moveable toward a plug axis to taper or remove material from the plug below the plug face

AI summary
A plug tool produces plugs having an aesthetic exterior surface common to a donor board. The tool can include a cutting edge that rotates about a tool axis and advances the tool into a donor board face to produce a plug having a plug face including the aesthetic exterior surface. A stabilizer can simultaneously engage the donor board face as the tool rotates and impair the tool from walking as the cutting edge penetrates the face. The tool can have a cutting end with compound angled surfaces extending from certain cutting edges to cut and move material away from the plug during cutting. The tool can be in a kit with a plug getter that is moveable to detach the plug from the donor board and/or a plug locator defining a plug aperture sized to extend around the plug, locating it relative to a fastener hole defined by a board.
