Bevel Saw Guide Plate for Consistent Bevel Cut Location
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bevel saws are limited in accurately making bevel cuts at various angles due to the variability of the cut location relative to the bevel angle, requiring multiple cut guides for each angle and making precise cuts difficult.
Innovation Solution
The bevel saw design includes a motor, arbor, and base plate with a bevel guide that can selectively vary the bevel angle between the blade plane and the base plate, utilizing a guide plate with non-concentric circular arc-shaped slots and a bevel guide mount for precise angle adjustment, allowing for consistent blade location and accurate cuts across a range of angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional bevel guide is used that permits bevel angle to be selectively varied, then the bevel angle can be adjusted to different values, but the cut location varies relative to the bevel saw with the bevel angle
Solution Approach 1:
The guide plate employs non-concentric circular arc-shaped slots where the first circular arc-shaped slot has a different radius of curvature and origin than the second circular arc-shaped slot. This asymmetric configuration ensures that as the bevel angle varies, the blade location remains consistent relative to the base plate, resolving the contradiction between angle adaptability and cut location precision
Solution Approach 2:
The guide plate acts as an intermediary mechanism between the bevel guide and the blade assembly. Through its specifically designed non-concentric circular arc-shaped slots, it mediates the relationship between angle adjustment and blade position, allowing angle variation while maintaining consistent cut location
2Manufacturing precision
If multiple cut guides are provided for different bevel angles, then accurate cuts can be made at various angles, but the device complexity increases
Solution Approach 1:
The guide plate with non-concentric circular arc-shaped slots serves multiple functions simultaneously: it guides the blade at various bevel angles while maintaining consistent cut location, eliminates the need for multiple separate cut guides, and provides a universal solution for all angle adjustments within the bevel cut angular range-of-motion
Solution Approach 2:
The invention merges the functions of multiple angle-specific cut guides into a single guide plate structure. The non-concentric circular arc-shaped slots combine the guidance functions for different angles into one integrated component, reducing device complexity while maintaining cut accuracy across all angles
3Reliability
If the bevel guide is securely attached to the base plate, then the bevel angle can be precisely maintained, but the attachment structure becomes more complex
Solution Approach 1:
The bevel guide mount includes a reinforcing structure with pre-positioned openings that are designed to receive fasteners. This preliminary configuration of the mounting structure ensures secure attachment and stable angle maintenance while keeping the overall design simple and straightforward to assemble

AI summary
Bevel saws configured to make a bevel cut in a workpiece are disclosed herein. The bevel saws include a motor and an arbor configured to operatively attach a circular saw blade to the bevel saws and to rotate the circular saw blade within a blade plane. The bevel saws further include a base plate that defines an arbor-facing side and an arbor-opposed side. The arbor is operatively attached to the arbor-facing side of the base plate. The bevel saws also include a bevel guide configured to selectively vary a bevel angle between the blade plane and the arbor-opposed side of the base plate within a bevel cut angular range-of-motion to selectively vary an angle of the bevel cut within the workpiece. The bevel saws may include a bevel guide mount configured to operatively attach the bevel guide to the base plate.
