Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If two layers of sliding rails are used to achieve secondary amplification of stroke, then the culture carrier can fully extend out, but the overall stiffness and stability of structure significantly decrease causing deformation or swaying
Solution Approach 1:
The invention divides the stroke amplification function into two independent stages: the first sliding rail assembly provides primary stroke amplification, and the second sliding rail assembly provides secondary stroke amplification. This segmentation allows each stage to contribute to the total extension distance while maintaining structural integrity through separate, optimized designs rather than a single complex extended structure
Solution Approach 2:
The invention introduces a vertical dimension to the stroke amplification mechanism by stacking two sliding rail assemblies at different heights (first sliding rail at upper level, second sliding rail at lower level). This dimensional arrangement enables the culture carrier to achieve full extension through combined horizontal and vertical motion paths, increasing the effective extension distance without compromising the lateral stiffness of individual rail assemblies
2Length of moving object
If two layers of sliding rails are used to achieve secondary amplification of stroke, then the culture carrier can fully extend out, but the position of the culture carrier deviates from the target position due to lateral bending moment
Solution Approach 1:
The invention introduces intermediate connecting structures (including guide rails and positioning mechanisms) between the first and second sliding rail assemblies that act as mediators to maintain proper alignment and reduce lateral bending moments. These intermediary elements ensure that the culture carrier remains positioned accurately at the target location while still achieving full extension through the two-stage amplification mechanism
3Length of moving object
If two layers of sliding rails are used to achieve secondary amplification of stroke, then the culture carrier can fully extend out, but the number of parts increases and assembly becomes complex
Solution Approach 1:
The invention merges the stroke amplification function with the support function by integrating the second sliding rail assembly into the overall structure in a way that it serves dual purposes: providing secondary stroke amplification while also supporting the culture carrier during extended positions. This merging reduces the need for separate structural elements and simplifies the overall assembly process

Implementation Method 1
a slide power transmission device, which is connected, via a coupling, to an output shaft of the slide drive motor configured to output rotational power and can convert the rotational motion of the output shaft into a linear displacement in a direction of width of the incubator body

AI summary
The present application provides an culture vessel active-oscillation slide mechanism and a shaker incubator, which can improve the overall stiffness and stability of the slide mechanism to avoid the creation of lateral bending moment while ensuring the culture vessel in the shaker incubator to fully extend out, and can also simplify the assembly complexity of a stroke amplification mechanism and reduce the number of parts. The culture vessel active-oscillation slide mechanism comprises a slide power transmission device, a slide stroke amplification mechanism and a slide mounting plate. The slide power transmission device can convert a rotational motion of an output shaft of a slide drive motor into a linear displacement in a direction of width. The slide stroke amplification mechanism amplifies the stroke of the linear displacement of the slide power transmission device in the direction of width. Rigid multi-stage rails are mounted on two sides of the slide mounting plate in a direction of length of the incubator body. In the multi-stage rails are configured to, by means of stages of rails partially sliding out relative to each other, support a culture vessel carrier mounting plate that fully extends out after the stroke is amplified.
