Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing saw guides for handheld circular saws lack versatility and precision in making angled cuts, as they often require complex configurations and are not easily portable for on-site use.
Innovation Solution
A portable saw guide with a pivoted, adjustable saw engagement track and interengaging angular locking positions on a curvilinear support surface, allowing for precise angular cuts and easy transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a portable saw guide uses a simple guide configuration, then ease of operation and portability are improved, but cutting precision and angular accuracy deteriorate
Solution Approach 1:
The guide track is made pivotally adjustable relative to the support surface, allowing dynamic repositioning between 0 and 45 degrees. This dynamic capability enables the guide to adapt to different cutting angles while maintaining precision through the interengaging locking mechanism that secures the track at specific angular positions.
Solution Approach 2:
The curvilinear support surface portion provides a curved path along which the guide track can pivot. This curved geometry enables smooth angular adjustment while the interengaging locking positions on the curvilinear surface ensure precise angular accuracy at multiple predetermined angles.
2Manufacturing precision
If a saw guide uses complex configurations to achieve precise angled cuts, then cutting precision is improved, but device complexity and portability deteriorate
Solution Approach 1:
The guide is divided into distinct functional segments: a support surface, a pivotally mounted guide track, and an interengaging locking mechanism. This segmentation allows each component to perform its specific function independently, simplifying the overall design while achieving precise angular cuts through the coordinated action of these modular elements.
Solution Approach 2:
The guide track serves multiple functions: it provides a straight guide edge for the saw, enables angular adjustment up to 45 degrees, and locks at multiple predetermined angles. This multi-functionality reduces the need for separate components for each function, thereby reducing overall device complexity while maintaining precision.
3Ease of operation
If a saw guide is designed for on-site portability, then ease of transportation is improved, but stability and setup reliability deteriorate
Solution Approach 1:
The interengaging locking mechanism automatically engages and locks the guide track at predetermined angular positions without requiring external tools or complex assembly steps. This self-locking capability ensures reliable setup stability while maintaining portability, as the guide can be quickly deployed and secured at any required angle.

AI summary
The invention provides a portable folding saw guide for hand held circular saws that allow the user to make different cross angled cuts to a work piece positioned thereon. The guide uses an adjustable guide track in which the saw is engaged which can be sequentially positioned at different cross angle incremental orientation by the user in a self-contained portable platform structure. The saw guide has hinges that allow the bottom surface of one of the work surface portions to be folded up against the bottom surface of the other work surface portion so that the saw guide can be folded, transported to a use location, unfolded and used. The saw guide plate supports and engages the saw on one side of the saw only.
