Swivelable Support for Rapier Guide Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for setting the position of a stationary guide on a weaving machine are complex and unreliable, making precise alignment with reference elements difficult, especially when those elements are not directly accessible.
Innovation Solution
A device comprising a first and second support part, with the first support part mounted swivelably about a virtual axis outside itself, allowing for precise alignment of the stationary guide with reference elements using a four-joint linkage mechanism and eccentric axles for adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the stationary guide is mounted directly to the frame using conventional mounting structures, then the mounting is simple and direct, but precise alignment with reference elements located at inaccessible positions cannot be achieved
Solution Approach 1:
The patent introduces a first support part as an intermediary component between the stationary guide and the frame. This support part is mounted swivelably about a virtual axis that lies outside the first support part, enabling indirect adjustment of the stationary guide's position to achieve precise alignment with reference elements that are not directly accessible to the mounting structure.
2Reliability
If conventional direct mounting methods are used, then the structure is simple, but repeated adjustments are required and reliability is low
Solution Approach 1:
The first support part is designed to be movable (swivelable) about a virtual axis during the positioning process, allowing dynamic adjustment of the stationary guide's orientation. After positioning is complete, the support part can be fixed to achieve the desired position, providing both adjustability and stability.
3Measurement precision
If the virtual axis is placed inside the first support part, then the mounting structure is compact, but alignment with reference elements at inaccessible positions becomes impossible
Solution Approach 1:
The virtual axis serves as a conceptual intermediary that extends beyond the physical boundaries of the first support part. This allows the rotation center to be positioned at locations that are not directly accessible to the mounting structure, enabling alignment with reference elements located at inaccessible positions while maintaining a compact overall structure.
