Work Support for Hand-Held Tools with Cutting Trough
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for handling hand-held cutting and drilling tools, such as angle grinders, lack effective solutions for ensuring occupational safety and precise, clean handling on-site, often resulting in environmental contamination from dust and chips.
Innovation Solution
A work surface with a cutting trough and adjustable lids that allows for safe positioning of materials, minimizes slipping, and integrates a suction system for dust collection, along with a swivel arm for enhanced support and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cutting stand is used to guide hand-held cutting tools, then occupational safety is improved, but the device becomes stationary and unsuitable for mobile on-site work
Solution Approach 1:
The work surface is designed with movable and adjustable components including a swivel arm that can rotate and extend to provide support at different positions. The entire work surface can be moved to different locations, combining the safety benefits of a guided cutting system with the mobility needed for on-site work.
2Adaptability or versatility
If cutting is performed on-site without a dedicated work surface, then mobile processing is enabled, but environmental contamination from dust and chips increases
Solution Approach 1:
The cutting trough is designed as a separate, removable component that can be detached from the work surface. This allows the trough to be used independently for containing dust and chips during mobile cutting operations, while the work surface can be used separately for other support functions.
Solution Approach 2:
The cutting trough acts as an intermediary structure between the cutting tool and the work surface, capturing dust and chips generated during cutting operations. The trough can be positioned to receive debris while allowing the cutting tool to operate above it.
3Ease of operation
If materials are placed directly on the work surface for cutting, then easy handling is achieved, but processing marks and damage can occur on the surface
Solution Approach 1:
The work surface is segmented into distinct functional zones including a cutting area with the trough, support areas with profile surfaces, and clear zones where materials should not be placed. This segmentation guides proper material positioning and prevents damage to the work surface while maintaining ease of operation.
4Ease of manufacture
If the work surface has a fixed design, then manufacturing simplicity is maintained, but adaptability to different materials and tools is reduced
Solution Approach 1:
The work surface is designed with multiple functional elements that serve different purposes: profile surfaces for preventing slips, a cutting trough for dust collection, measurement marks for precision work, and a swivel arm for extended support. This multi-functional design allows a single work surface to accommodate various cutting tools, materials, and working conditions without requiring multiple specialized surfaces.
