Cross-Guide Oscillating Table Coupling for High-Frequency Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oscillating devices with cross guideways have a complex structure that leads to increased weight and size, necessitating higher electrical power consumption and lower oscillation frequencies, especially in high-frequency ranges, due to the use of intermediary stages and heavy movable parts, which also cause vibration noise issues.
Innovation Solution
The oscillating device is designed with a simplified cross guide configuration that eliminates the intermediary stage, utilizing multiple cross guides arranged in a specific overlapping pattern, with X-axis and Y-axis linear guides overlapping in the Z-axis direction, and direct fixation of carriages without an intermediary stage, enhancing frequency characteristics through downsizing and weight reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an intermediary stage is used to couple carriages of linear guides, then the cross guide can be assembled, but the number of components increases and the cross guide becomes heavy
Solution Approach 1:
The patent merges the X-axis carriage and Y-axis carriage into a single integrated cross guide component. The carriages are directly coupled without an intermediary stage, eliminating the need for separate coupling components. This integration reduces the total number of parts and decreases the overall weight of the moving cross guide assembly while maintaining the ability to assemble the components using standard linear guide interfaces.
2Device complexity
If the cross guide structure is complex with intermediary stages, then coupling is achieved, but the movable part weight increases requiring greater electrical power
Solution Approach 1:
By integrating the carriages directly without intermediary stages, the patent simplifies the cross guide structure. This reduction in structural complexity decreases the total mass of the movable part, which in turn reduces the electrical power required to accelerate and decelerate the moving mass during oscillation operations.
3Stability of the object's composition
If the movable part is heavy, then structural stability is improved, but the upper limit of oscillation frequency decreases
Solution Approach 1:
The integrated cross guide design reduces the movable part weight while maintaining structural integrity through direct carriage coupling. The simplified structure with fewer components reduces the total mass that needs to be accelerated, thereby increasing the upper limit of oscillation frequency without compromising the stability required for accurate positioning and operation.
4Force
If the cross guide is heavy, then load capacity is improved, but the resonance frequency of the movable part decreases causing vibration noises
Solution Approach 1:
The patent achieves an optimized balance between load capacity and vibration noise by integrating the carriages directly. This simplification reduces the movable mass, which increases the resonance frequency of the cross guide assembly. By raising the resonance frequency above the operational frequency range, vibration noises and unwanted resonances are minimized while the direct coupling maintains sufficient load capacity through efficient force transmission.

AI summary
An oscillating device (1) comprises an X-axis, Y-axis and Z-axis oscillating units (100, 200, 300) configured to oscillate a vibrating table (400) in the X-axis, Y-axis and Z-axis directions respectively. A plurality of XY sliders (364) each have a first and second linear guideway (364A, 364B) coupling the vibrating table and the Z-axis oscillating unit slidably in the X-axis and Y-axis direction respectively. The first linear guideway has a first carriage (364Bb) configured to engage with a first rail (364Ba) slidably in the X-axis direction, and the second linear guideway (364A) has a second carriage (364Ab) configured to engage with a second rail (364Aa) slidably in the Y-axis direction. Two of the XY sliders (364) being adjacent to each other are arranged while orienting their orientations in the Z-axis direction opposite to each other.
