Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If multiple moving component sets are linked together to achieve synchronous extension and contraction, then the lifting mast can raise its top to high places, but the movement becomes unsmooth due to lack of support between components
Solution Approach 1:
Guide rails are introduced as intermediary components between the moving component sets and support tubes. The guide rails extend along the support tubes and provide continuous contact surfaces for the moving components, ensuring smooth guidance and support during extension and contraction movements while maintaining the synchronous operation capability
Solution Approach 2:
The linkage mechanism uses threaded sections on active rods that can dynamically adjust the position of moving component sets along the support tubes. This dynamic adjustment capability allows the system to maintain smooth movement while achieving the required extension heights for various applications
2Productivity
If active rods and hollow rods are used to link moving component sets, then synchronous movement is achieved, but the process of erecting antennas or lines is affected due to unsmooth operation
Solution Approach 1:
Guide rails serve as intermediary elements between the linkage rods and moving component sets. These guide rails provide continuous support and smooth contact surfaces, eliminating the unsmooth operation that previously affected antenna installation efficiency while preserving the synchronous movement capability of the linkage mechanism
3Device complexity
If multiple moving component sets are connected without auxiliary support components, then the structure remains simple, but the extension and folding process becomes unsmooth
Solution Approach 1:
Guide rails are introduced as auxiliary intermediary components that provide smooth contact surfaces between moving component sets and support tubes. While these components add some structural elements, they significantly improve movement smoothness with minimal increase in overall system complexity, as the guide rails integrate seamlessly with the existing support tube structure

Implementation Method 1
a plurality of balls are embedded in a wall of the screw hole of the moving base, so that the moving base can smoothly reciprocate on the threaded section of the linkage rod through the balls
Implementation Method 2
The linkage rod comprises a threaded section located on an outer surface thereof... the moving base can smoothly reciprocate on the threaded section of the linkage rod
