Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single gear is used to mesh between sliding auxiliary devices, then the structure is simpler, but the reliability and synchronization of movement between multiple rails deteriorates
Solution Approach 1:
The patent divides the single gear function into two separate gears: a first gear meshing with the first sliding auxiliary device and a second gear meshing with the second sliding auxiliary device. This segmentation allows independent control and meshing for each rail system, improving movement synchronization and reliability while maintaining reasonable structural complexity through modular design.
2Stability of the object's composition
If gears are fixed to the rails, then the meshing is more stable, but the gears cannot rotate independently causing movement delays
Solution Approach 1:
The patent applies different quality requirements to different parts of the gear system. The gears are positioned adjacent to the rails with their rotation axes extending along the longitudinal direction of the rails, allowing stable meshing engagement while maintaining independent rotation capability. This local configuration enables both stable meshing and independent gear rotation without conflict.
Solution Approach 2:
The gear acts as an intermediary element between the sliding auxiliary devices and the rails. By positioning the gears adjacent to the rails rather than fixing them directly to the rails, the system allows the gears to rotate independently on their rotation axes while maintaining stable meshing engagement with the sliding auxiliary devices, resolving the conflict between meshing stability and rotational independence.
3Device complexity
If the gear rotation axis is perpendicular to the rail, then the meshing is simpler, but the synchronization and alignment between multiple rails deteriorates
Solution Approach 1:
The patent changes the orientation of the gear rotation axis from perpendicular to the rail (traditional configuration) to parallel with the longitudinal direction of the rail. This dimensional change in the rotation axis orientation enables better synchronization and alignment between multiple rails while maintaining manageable meshing complexity through the adjacent positioning of the gears.
