Rolling Guide Head Module Support for Precise Liquid Jet Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid jet heads face challenges in ensuring defined position accuracy and rigidity during the movement of fluid jet modules due to the use of slip guides, which leads to difficulty in maintaining precise alignment and stability.
Innovation Solution
The implementation of rolling guides extending in the first direction for guiding the movement portion with respect to the fixing portion, along with a distributed arrangement of rolling guides and hardening treatments to enhance position accuracy and rigidity, and the use of position detection units to facilitate precise adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a slip guide is used to guide the movement portion with respect to the fixing portion, then the device complexity is reduced, but the position accuracy and rigidity deteriorate
Solution Approach 1:
The patent replaces the slip guide (friction-based mechanical guidance) with a rolling guide (roller-based mechanical guidance). The rolling guide includes a roller that rotates along a groove, converting sliding friction to rolling friction, thereby reducing frictional forces and improving position accuracy while maintaining reasonable structural complexity.
2Ease of manufacture
If a slip guide is used to guide the movement portion with respect to the fixing portion, then the ease of manufacture is improved, but the rigidity and stability deteriorate
Solution Approach 1:
The patent replaces the slip guide with a rolling guide that uses a roller element. This substitution maintains manufacturing feasibility while significantly improving the stability and rigidity of the movement portion during operation, as rolling contact provides more stable and predictable motion characteristics than sliding contact.
3Ease of operation
If the total length of the rolling guide is made shorter than the fixing portion, then the ease of operation and access is improved, but the position accuracy may deteriorate
Solution Approach 1:
The patent employs multiple rolling guides distributed at different positions along the movement portion rather than a single long rolling guide. This segmentation approach provides multiple contact points that collectively ensure position accuracy while allowing the individual guide segments to be shorter and more accessible for maintenance and operation.
