Skimming Tool Pole Attachment With Extended Jaws
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plastering tools are inflexible and inadequate for smoothing and levelling wet finish coat plaster on surfaces, particularly on uneven substrates and hard-to-reach areas, limiting efficiency and finish quality.
Innovation Solution
A pole attachment with a clamp and clamping mechanism, featuring jaws and wings for easy attachment to a skimming tool, providing lateral support and enabling the use of a extendable pole for reaching higher areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rigid and inflexible Darby tool is used for levelling, then it can rule off backing plaster, but it cannot smooth and level finish coat plaster on uneven substrates
Solution Approach 1:
The patent applies the dynamics principle by making the skimming tool body flexible rather than rigid. The tool comprises a flexible body that can conform to uneven substrates, allowing it to adapt dynamically to the surface being worked on. This flexibility enables the tool to smooth and level finish coat plaster on irregular surfaces while maintaining sufficient structural integrity through its elongate design and material properties.
2Length of moving object
If conventional stainless steel sheet trowels are used, then they can apply plaster, but they cannot reach hard-to-reach areas such as ceilings
Solution Approach 1:
The patent applies segmentation by dividing the tool into modular components: a handle, an elongate flexible body, and an optional extendable pole attachment. This segmentation allows the tool to be configured in different ways - the pole can be attached to extend reach for ceilings and hard-to-reach areas, while the flexible body maintains the necessary length and flexibility for effective plastering. The modular design reduces overall system complexity while enabling extended functionality.
3Ease of operation
If a pole attachment with narrow jaws is used for easy attachment, then it simplifies installation, but it may compromise lateral support of the pole
Solution Approach 1:
The patent applies the dimensionality change principle by extending the jaws in a width direction perpendicular to the gripping direction. The jaws have a first dimension for gripping the tool body and a second dimension (width) that provides lateral support. This creates a two-dimensional engagement surface that simultaneously achieves easy attachment through the gripping function while providing robust lateral support through the extended width, effectively resolving the contradiction by operating in multiple spatial dimensions.
