Guide Carriage Saw Positioning With an Adjustable Blade Stop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices require the guide carriage to be placed on a guide rail to adjust the position of a tool device, which limits flexibility and convenience in positioning the tool relative to the workpiece.
Innovation Solution
The device incorporates adjusting elements with a stop that allows the tool to be fixed in a desired position without being on the guide rail, using a guide carriage that can be displaced parallel to a reference line formed by a plastic splinter protection strip, with position fixing elements and adjusting elements that can be moved transversely to adjust the tool's distance from the guide carriage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the guide carriage is placed on the guide rail to adjust the position of the tool device, then the positioning accuracy is improved, but the flexibility and convenience of positioning are reduced
Solution Approach 1:
The positioning system is divided into two independent parts: (1) the guide rail with reference line that provides accurate positioning reference, and (2) the guide carriage with adjustable positioning elements that can be configured independently. The positioning elements on the guide carriage can be adjusted without requiring the carriage to be mounted on the guide rail, enabling flexible positioning setup while maintaining accuracy when needed.
Solution Approach 2:
The positioning elements are pre-adjusted and configured on the guide carriage before the carriage is placed on the guide rail. The adjusting elements can be positioned in advance to define the desired tool position relative to the reference line, so that when the carriage is mounted, the tool is already in the correct position, eliminating the need for continuous alignment during operation.
2Adaptability or versatility
If the adjusting elements are continuously adjustable, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The positioning elements are designed to be movable and adjustable during the setup phase, allowing continuous adaptation to different tool positions. The adjusting elements can be freely positioned along the guide carriage to accommodate various tool diameters and positioning requirements. Once adjusted, the elements maintain their position to provide stable reference during operation, combining the benefits of adaptability and simplicity.

AI summary
The invention relates to an apparatus having a guide carriage (5) which can be fitted onto a guide track (1) and is displaceable thereon having position-fixing elements (6, 7) for fixing a tool device (8) on the guide carriage (5), having an adjusting element (10) in order during adjustment of the position-fixing elements (6, 7) to bring a tool (9) of the tool unit (8) into a defined position. In order to simplify the position fixing of a tool device (8), in particular a handheld circular saw, on the guide carriage (5), the adjusting element (10) has an adjusting stop (13) against which the tool (9), in particular a saw blade, can be placed.
