Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support devices for large, cylindrical bodies with geometric deviations from rotational symmetry experience high surface and edge pressures due to inaccuracies in concentricity and deflections along the axis of rotation, leading to potential damage.
Innovation Solution
A support device with two support rollers mounted on an upper frame, an intermediate frame, and a subframe, featuring pivotable cylindrical surfaces and axes to allow self-adjustment for geometric deviations, minimizing high surface and edge pressures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single rigid roller is used to support the cylindrical body, then the device structure is simple, but it cannot compensate for concentricity inaccuracies leading to high edge pressures and potential damage
Solution Approach 1:
The support device employs dynamically adjustable support rollers that can independently move along the cylindrical body's surface. This dynamic capability allows the rollers to adapt to concentricity deviations and deflections, compensating for geometric imperfections while maintaining reliable support without requiring an overly complex rigid structure
2Adaptability or versatility
If two parallel support rollers are used with a rocker-like mounting, then self-adjustment for the axis is achieved, but deflections along the rotation axis still cause increased edge pressures
Solution Approach 1:
The support system is segmented into multiple independently adjustable support rollers distributed along the cylindrical body. Each roller can individually compensate for local deflections and geometric deviations, preventing concentrated edge pressures while maintaining the self-adjustment capability for axis alignment
Solution Approach 2:
The invention extends the adjustment capability from a single rocker axis to multiple degrees of freedom, allowing support rollers to compensate for deflections along the rotation axis by moving in additional dimensions, thereby reducing edge pressures caused by longitudinal deflections
3Stability of the object's composition
If support rollers are fixed at a predetermined distance, then the device structure is stable, but it cannot adapt to shape and position deviations of the cylindrical body
Solution Approach 1:
The support rollers are mounted on adjustable carriers that can dynamically change their positions along the cylindrical body while maintaining stable support. This dynamic positioning capability allows adaptation to shape and position deviations without compromising the overall structural stability of the support device
