Surface Repair Tool With Integrated Applicator And Sanding Pad
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface repair tools require multiple tools for applying and sanding repair compounds, leading to inefficiencies, waste, and contamination.
Innovation Solution
A single tool with a handle, collapsible container, applicator blade, and integrated sanding pad that allows for the application and sanding of repair compounds without the need for separate tools, minimizing waste and contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate tools are used for applying and sanding repair compound, then each tool can be specialized for its function, but the overall process becomes more complex and requires more tools
Solution Approach 1:
The patent combines the application blade and sanding pad into a single integrated tool handle assembly. The blade for applying repair compound and the sanding pad for smoothing dried compound are both attached to the same handle, eliminating the need for separate tools and reducing overall device complexity while maintaining functional versatility
Solution Approach 2:
The single tool handle is designed to perform multiple functions: it holds the container, supports the application blade for spreading compound, and incorporates the sanding pad for finishing. This multi-functional design allows one tool to replace multiple specialized tools
2Ease of operation
If a putty knife is dipped into a container of spackling, then the spackling can be applied to the surface, but waste and contamination of the spackling occurs
Solution Approach 1:
The patent extracts the spackling compound from the container and delivers it directly to the application blade through a controlled flow passage system. The blade receives compound through an orifice without needing to be dipped into the container, eliminating the contamination and waste associated with dipping methods
Solution Approach 2:
The flow passage acts as an intermediary mechanism between the container and the application blade. It controls the transfer of spackling compound, allowing precise dispensing through the orifice and preventing the blade from contacting the main body of compound in the container, thus avoiding contamination and excess waste

AI summary
A surface repair tool for repairing defects in surfaces includes a handle with an applicator blade extending from one end of the handle and a sanding device extending from the opposite end of the handle. The handle includes a receptacle into which is removably received a container of repair compound. The applicator blade includes an application surface and a flow passage that has an inlet and an orifice formed through the application surface. Squeezing the container causes repair compound in the container to flow through the flow passage of the applicator blade and out of the orifice where it is dispensed onto the applicator surface to be spread on a surface needing repair. Once the repair compound dries, the sanding device is used to sand the repair compound to a desire finish.
