Mitre Saw Side Handle Assembly for Maneuverability and Work Surface Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding compound mitre saws lack efficient handling mechanisms for easy maneuverability between locations, which hinders operator convenience and work surface extension during use.
Innovation Solution
Integration of D-shaped side handles made from plastic, which are flat on top and lie flush with the platforms and rotatable table, extending the work surface and providing secure attachment to the base assembly, along with a pivotally mounted bevel joint and guide rods for enhanced cutting capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If no side handles are provided on the base assembly, then the structure remains simple, but the operator cannot easily maneuver the saw between different locations
Solution Approach 1:
The side handles are integrally formed with the base assembly, merging the handling function into the base structure itself. This integration provides maneuverability benefits while avoiding the complexity of separate attachable handles, as the handles become an inherent part of the base assembly design
2Area of stationary object
If the top surfaces of handles are not flush with the platforms and rotatable table, then manufacturing is simpler, but the work surface cannot be extended
Solution Approach 1:
The top surfaces of the side handles are designed to be coplanar with the top surfaces of the platforms and rotatable table, merging these surfaces into a single extended work surface. This design extension provides additional workspace while the integral formation maintains manufacturing simplicity through unified structure

AI summary
A sliding compound mitre saw and a method of manufacturing such a sliding compound mitre saw, the compound mitre saw comprising: a base (6); a rotatable table (100) pivotally mounted within the base to enable the saw to perform mitre cuts, the base and rotatable table forming a base assembly with the top surfaces (102, 104) of the base and the rotatable table forming a work surface; a mount (27) pivotally mounted on the rear of the rotatable table to enable the saw to perform bevel cuts; a second base (222) pivotally mounted on the mount (27) to enable the saw to perform chop cuts; two parallel guide rods (200) rigidly attached to the second base (222) and which extend across the base assembly (6, 100), one guide rod being located above the other guide rod; a cutting unit (50) slideably mounted on the two guide rods which is capable of being slid along the length of the guide rods (200) over the base assembly (6, 100) to enable the saw to perform sliding cuts; wherein a handle (10) is mounted to each side of the base (6), the top surfaces (610) of which are flat and flush with the top surfaces (102, 104) of the base and the rotatable table to extend the work surface ; wherein each side of the base comprises a receiving section (600) which faces at least in an upward direction; the underside of each handle comprising a mating portion (620) which faces at least in a downward direction for engaging with a corresponding receiving section (600); wherein each handle is mounted on the base by being lowered (Arrow A) from above the base (6) onto the base (6) so that the receiving section engages with the mating portion, each handle being secured to the base with at least one fastener (608) when mounted on the base.
