Modular Electric Saw With Wheeled Dust Collection Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concrete cutting saws are large, heavy, and difficult to transport, and they generate significant dust and debris during operation, which can obscure the operator's view and is problematic when cutting indoors.
Innovation Solution
A cutting system with a wheeled base unit that can receive and adjustably position a handheld electric rotary cutting tool, allowing for up-cut or down-cut operations, and incorporates dust and debris collection systems to manage the generated waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional concrete cutting saw is used, then cutting capability is achieved, but the device is large, heavy, and difficult to transport
Solution Approach 1:
The cutting system is divided into separate components: a handheld electric rotary cutting tool and a wheeled base unit. The cutting tool can be detached and transported separately from the base unit, improving transportability while maintaining cutting capability.
Solution Approach 2:
The patent transitions from a traditional self-contained saw design to a modular system where the cutting tool operates in one dimension (handheld operation) while the base unit provides support in another dimension (dust collection and tool positioning).
2Object-generated harmful factors
If dust collecting assemblies are used, then dust and debris collection is improved, but the operator's view of the cutting area and blade position is obscured
Solution Approach 1:
The dust collection system uses a wheeled base unit positioned behind the cutting zone as an intermediary structure. This allows dust collection to occur without placing collection components in the operator's direct line of sight of the cutting area and blade position.
Solution Approach 2:
The dust collection functionality is relocated to a separate spatial dimension (the wheeled base unit positioned behind the cut), allowing it to operate effectively without interfering with the operator's forward view of the cutting operation.
3Ease of operation
If a handheld electric rotary cutting tool is used with a wheeled base, then transportability is improved, but dust and debris collection becomes more complex
Solution Approach 1:
The wheeled base unit serves multiple functions: it provides structural support for the cutting tool, enables easy transport through wheels, and incorporates dust collection provisions. This multi-functionality reduces the need for separate dedicated components.
Solution Approach 2:
The patent combines the cutting tool support structure with dust collection provisions in a single integrated wheeled base unit, simplifying the overall system while maintaining both transportability and dust collection capabilities.
