Printer Guidance Rail Non-Equidistant Mounting Sites
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The equidistant arrangement of mounting sites on guidance rails in printers leads to increased vibrations, affecting the longevity and precision of the print head carriage, as it creates regular patterns that resonate with specific frequencies induced by the carriage's movement.
Innovation Solution
The mounting sites on the guidance rails are arranged non-equidistantly, with varying distances between adjacent sites to break the regularity and reduce resonance frequencies, thereby minimizing vibrations. This can be achieved by defining equidistant center positions with mounting sites positioned within tolerance intervals and randomly or alternately varying the distances between adjacent sites.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If mounting sites are arranged equidistantly on the guidance rail, then the manufacturing and installation process is simplified, but the guidance rail becomes more susceptible to vibrations at specific resonance frequencies
Solution Approach 1:
The patent applies asymmetry by deliberately arranging mounting sites at non-equidistant positions along the guidance rail. This asymmetric distribution breaks the periodic structure that would otherwise resonate with the print head carriage movement, thereby reducing vibration susceptibility while maintaining manufacturing feasibility through standardized mounting components.
Solution Approach 2:
The patent changes the spatial parameter of mounting site distribution from equidistant to non-equidistant arrangement. By varying the distances between adjacent mounting sites, the structural resonance characteristics of the guidance rail are modified to avoid matching the excitation frequencies generated during printing operations.
2Object-affected harmful factors
If mounting sites are arranged non-equidistantly to reduce vibrations, then vibration susceptibility decreases, but the manufacturing complexity increases
Solution Approach 1:
The patent applies asymmetry by deliberately arranging mounting sites at non-equidistant positions along the guidance rail. This asymmetric distribution breaks the periodic structure that would otherwise resonate with the print head carriage movement, thereby reducing vibration susceptibility while maintaining manufacturing feasibility through standardized mounting components.
3Stability of the object's composition
If the guidance rail is rigidly fixed at equidistant mounting sites, then structural stability is improved, but precision of the print head carriage deteriorates due to vibrations
Solution Approach 1:
The patent applies asymmetry by deliberately arranging mounting sites at non-equidistant positions along the guidance rail. This asymmetric distribution breaks the periodic structure that would otherwise resonate with the print head carriage movement, thereby reducing vibration susceptibility while maintaining manufacturing feasibility through standardized mounting components.

AI summary
1. A guidance rail (20) for a print head carriage and a printer having a guidance rail (20) are provided. The guidance rail (20) has mounting sites (12-1, 12-2) arranged essentially in a row and configured for applying mounting elements for mounting the guidance rail (20) to a printer. At least two distances (d12, d23, d34) between any adjacent mounting sites (12-i, 12-(i+1)) are non-equal, in order to reduce the susceptibility of the guidance rail (20) to vibrations induced by movements of the print head carriage.
