Power Tool Ski Elevates Base to Block Dust Intake
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power tools, especially chipping hammers, suffer from reduced lifespan due to the intake of dust, grit, and debris, which damages components, and are uncomfortable to use due to weight and vibration, leading to fatigue and health issues.
Innovation Solution
A power tool ski accessory that elevates the tool above the work surface, preventing dust and debris from entering the tool and reducing strain on the power cord, featuring a bridge and side walls with a securing mechanism to detachably couple to the tool, allowing the power cord to pass through and maintaining contact with the surface to prevent kinking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power tool is placed directly on the work surface, then the tool is stable and easy to position, but dust and debris enter the tool through the intake, damaging motor components and reducing lifespan
Solution Approach 1:
The patent introduces an intermediary structure (a base or platform with elevated edges) that positions the power tool above the work surface. This intermediary prevents direct contact between the tool intake and dust/debris on the surface, while still allowing the tool to remain stable and properly positioned for operation.
Solution Approach 2:
The patent elevates the power tool from the horizontal work surface plane to a higher vertical position using a base structure. This dimensional change in the vertical direction creates separation between the tool intake and harmful particles on the surface, preventing contamination while maintaining operational stability.
2Reliability
If the power tool rests directly on the work surface, then the tool is stable, but the power cord and base suffer wear and tear from movement and contact with the surface
Solution Approach 1:
The patent introduces a protective base or platform as an intermediary between the power tool and the work surface. This base absorbs the wear and tear from contact with the surface, preventing direct damage to the power cord and tool base, while still providing stable positioning.
3Reliability
If the power tool is elevated from the work surface, then dust and debris are prevented from entering the tool, but the tool requires additional support structure and complexity
Solution Approach 1:
The patent designs the base structure to serve multiple functions simultaneously: it elevates the tool to prevent dust intake, provides stable support, protects the power cord from wear, and facilitates easy attachment/detachment of the tool. This multi-functionality reduces the need for separate protective devices.
Solution Approach 2:
This principle does not apply to this patent as it relates to visual properties rather than functional protection mechanisms.

AI summary
A power tool accessory for elevating the base of a power tool from off a work surface and a method of use. The accessory or ski comprises a bridge, a first side wall coupled to the bridge, and a second side wall coupled to the bridge opposite the first side wall. The bridge, the first side wall, and the second side wall form an upper surface and an opening through which a power cord may pass. The upper surface is configured to receive a base of a power tool. Because the ski elevated the power tool from off of a work surface, dust, debris, and grit is not brought into the intake of the power tool, the power cord is not kinked, and the base of the power tool is not worn down on the work surface.
