Sanding Block Coupling Accessory for Extension-Stick Reach
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanding blocks require manual handling, necessitating professionals to climb stairs or scaffolding for reaching high surfaces, increasing the risk of accidents and complicating the work process.
Innovation Solution
A coupling accessory that attaches a sanding block to a painter's extension stick, allowing for manual sanding of distant surfaces without climbing, featuring a support area for the block and a cylindrical section for the stick connection, with optional stabilizing elements and a light for detecting irregularities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sanding block is held directly by hand, then the sanding block can be controlled precisely, but the user must climb stairs or scaffolding to reach high surfaces, increasing safety risks and work complexity
Solution Approach 1:
The patent introduces an extension stick as an intermediary tool between the user and the sanding block. The extension stick allows the user to reach high surfaces without climbing, thereby eliminating the safety risk while maintaining control over the sanding block through the extended reach mechanism
2Reliability
If an extension stick is used to reach high surfaces, then safety is improved by avoiding climbing, but the sanding block requires additional attachment mechanisms, increasing device complexity
Solution Approach 1:
The extension stick is designed with multi-functionality, serving both as a reaching mechanism and as an attachment system for the sanding block. The universal design allows the same extension stick structure to provide both the extended reach for safety and the mounting interface for the sanding block, thereby avoiding additional complexity
