Engineering Contradiction Analysis
1Manufacturing precision
If mechanical synchronization structure is used to drive two sliding blocks along two guide rails, then synchronization performance is improved, but device complexity and cost increase significantly
Solution Approach 1:
The patent divides the synchronization control into two independent parts: the upper sliding block is controlled by a first motor through a first timing belt, and the lower sliding block is controlled by a second motor through a second timing belt. This segmentation eliminates the need for complex mechanical synchronization structures while maintaining synchronization performance through independent motor control.
Solution Approach 2:
The patent replaces the mechanical synchronization structure with an electrical control system. Instead of using mechanical linkages to synchronize the movement of two sliding blocks, the invention uses two independent motors controlled by a control system to drive each block separately, thereby eliminating complex mechanical synchronization mechanisms.
2Manufacturing precision
If mechanical synchronization structure is used for large distance between guide rails, then synchronization is achieved, but weight and cost become very high
Solution Approach 1:
The patent segments the drive system into two independent drive units, each consisting of a motor and timing belt assembly. This allows each unit to be optimized independently and reduces the overall weight compared to a single heavy mechanical synchronization structure spanning the entire distance between guide rails.
Solution Approach 2:
The patent replaces heavy mechanical synchronization structures with lighter electrical motor-driven timing belt systems. The timing belts are significantly lighter than mechanical linkages or rigid synchronization structures, reducing the overall weight of the moving components while maintaining synchronization capability.
3Device complexity
If dual power driving is used to drive sliding blocks respectively, then device complexity is reduced, but synchronization errors cause torsion and potential damage to coupling structures
Solution Approach 1:
The patent introduces a flexible separation column as an intermediary element between the upper and lower sliding blocks. This flexible column can accommodate synchronization errors and positional deviations without transmitting damaging torsional forces to the coupling rod, thereby protecting the structural integrity while maintaining the simplicity of dual independent drive systems.
Solution Approach 2:
The patent changes the rigidity parameter of the connection between upper and lower sliding blocks by using a flexible separation column instead of a rigid coupling. This flexibility allows the system to tolerate synchronization errors from independent motors without causing damaging stress concentrations, thus improving reliability while maintaining simple dual-power driving.
4Stability of the object's composition
If rigid coupling is used between upper and lower sliding blocks, then structural stability is improved, but synchronization errors generate damaging torsion
Solution Approach 1:
The patent changes the rigidity parameter of the vertical rod from rigid to flexible by using a flexible separation column. This flexible connection maintains structural stability for normal operations while accommodating synchronization errors without generating damaging torsional forces, thus improving component durability.
Solution Approach 2:
The flexible separation column acts as an intermediary that decouples the rigid connection between upper and lower sliding blocks. It allows relative movement and rotation to accommodate synchronization errors while maintaining overall structural stability, preventing damage to coupling structures.
