Removable Circular Saw Mounting for Safer Bench Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Regular handheld circular saws pose safety hazards due to the need for multiple hole drilling, constant switch grip maintenance, and continuous power connection, violating safety standards.
Innovation Solution
A modified handheld circular saw design featuring a specialized power cable with specific wire connections and a secure attachment system to a bench, ensuring safe operation by bypassing hazardous connections and using a secure bolt system for attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a regular handheld circular saw is used, then it can perform cutting operations, but it requires drilling four holes on the bottom plate and constant switch grip maintenance which creates safety hazards
Solution Approach 1:
The system divides the cutting tool into two separate components: a stationary bench-mounted base unit containing the motor and blade, and a handheld remote control unit with switches. This segmentation eliminates the need for the handheld unit to contain hazardous electrical components while maintaining cutting functionality.
Solution Approach 2:
A long flexible power cable acts as an intermediary connection between the bench-mounted motor unit and the handheld control unit. This allows the control switches to be positioned safely away from the blade while still enabling operation of the cutting tool.
2Reliability
If the power cable is continuously connected to the wall outlet, then power is always available, but this creates safety violations and hazards
Solution Approach 1:
The hazardous power connection and motor components are extracted from the handheld unit and relocated to a stationary bench-mounted base unit. The handheld unit only contains control switches connected via a flexible power cable, removing the safety hazards from the mobile portion of the system.
3Ease of operation
If grips are added to keep switches at the 'ON' position, then the saw can operate, but this requires constant manual attention and creates safety issues
Solution Approach 1:
The control switches are segmented from the motor and blade assembly, placed in a separate handheld unit connected by a flexible power cable. This allows the switches to be positioned in a safe location away from the cutting zone while maintaining full control functionality.
