Portable Machine Tool Guiding System Position Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guiding systems for portable machine tools lack a reliable and easy-to-use mechanism for fixing the position of the guiding apparatus on the positive guidance unit, which limits precise positioning and ease of operation, especially in applications like surface milling machines where portability and versatility are crucial.
Innovation Solution
The proposed guiding system includes a position fixing unit with a fastening unit, a movably mounted latching element, and a spring element, allowing for a positive-locking and friction-locking connection between the guiding apparatus and the positive guidance unit, enabling precise positioning and easy release, thus enhancing the operational ease and versatility of portable machine tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a position fixing unit is added to fix the guiding apparatus on the positive guidance unit, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The latching element is designed to automatically engage with the guiding apparatus when the guiding system is assembled, fixing the position without requiring manual intervention or additional fastening operations. The spring element provides automatic engagement force, making the positioning process self-serviceing and eliminating the need for complex manual fixation mechanisms.
Solution Approach 2:
The patent replaces complex mechanical fastening systems with a simplified spring-loaded latching mechanism. Instead of using multiple screws, clips, or complex locking mechanisms, the invention uses a spring element to provide continuous engagement force on a simple latching element, significantly reducing mechanical complexity while maintaining positioning precision.
2Ease of operation
If a fastening unit with latching element is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The latching element automatically engages with the guiding apparatus structure during assembly, requiring no manual fastening operations. The spring element automatically provides engagement force, making the entire fastening process self-serviceing and extremely easy to operate - simply assemble the components and the latching mechanism does the rest.
Solution Approach 2:
The patent extracts the fastening function from complex manual operations and embeds it within the structure of the guiding apparatus itself. The latching element is integrated into the guiding apparatus body, and the spring element is pre-installed to provide automatic engagement, removing the need for separate fastening operations and simplifying user interaction.
