Saw Cut-Depth Guide With Fixed Arbor And Single Hydraulic Circuit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing saws for cutting hard materials, such as concrete, rock, and asphalt, face challenges in maintaining precise cut depth and alignment, especially when operating near utilities or structures that must not be cut, and often require multiple hydraulic circuits and specific machine types, limiting versatility.
Innovation Solution
A saw design with a fixed arbor and single hydraulic circuit that includes a cut-depth guide with a guide wheel and mounting plate to maintain cut depth, allowing operation on various machines without additional hydraulic connections, and features like a shield with an elongate mark for alignment and an on-board fluid supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a fixed arbor design is used, then cut depth precision is improved, but adaptability to different machine types deteriorates
Solution Approach 1:
The mounting plate is designed with multiple mounting hole patterns that can accommodate different machine types (skid-steer loaders, compact track loaders, mini excavators, etc.). This universal mounting design allows the same saw assembly to be adapted to various host machines while maintaining the fixed arbor configuration for precise cut depth control.
2Power
If multiple hydraulic circuits are used, then power delivery is improved, but device complexity deteriorates
Solution Approach 1:
The patent combines multiple hydraulic functions into a single hydraulic circuit. The single circuit delivers power for both the auger and the saw blade through a common hydraulic motor or coordinated motors, eliminating the need for separate hydraulic systems while maintaining adequate power delivery for both cutting and augering operations.
Solution Approach 2:
The single hydraulic circuit is designed to perform multiple functions - powering the saw blade for cutting hard materials and powering the auger for material displacement. This multi-functional hydraulic system reduces overall system complexity while maintaining the power necessary for both operations.
3Reliability
If specialized machines are required, then operational reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The saw assembly is designed with universal mounting capabilities that allow it to be installed on various types of existing equipment (skid-steer loaders, compact track loaders, mini excavators, etc.). This eliminates the need for specialized machines while maintaining operational reliability through proven mounting configurations and hydraulic connections on commonly available equipment.

AI summary
The present disclosure provides for a saw for cutting a hard material. The saw includes a housing, a motor mounted to the housing and an arbor mounted in a fixed position relative to the housing. The arbor can further include a saw blade, where the motor turns the arbor to rotate the saw blade. A shield mounted to the housing covers the saw blade, where the shield includes an elongate mark that aligns with the circumferential cutting edge of the saw blade. The housing further includes a cut-depth guide that includes a depth post that passes through a sleeve having a latch that can releasably engages the depth post to fix the position of the depth post relative to the sleeve. A guide wheel extends from the depth post, where the guide wheel contacts the hard surface to maintain a cut depth of the saw blade.
