Engineering Contradiction Analysis
1Speed
If telescopic axes with long travel distances are used to distribute movement across various machine elements, then the speed of each individual component is reduced, but the risk of carrier moving ahead of telescopic elements increases, leading to potential collisions and increased downtime
Solution Approach 1:
The patent implements dynamic control of the telescopic device by using a transmission device with different transmission ratios for different telescopic elements. This allows the system to adaptively adjust the movement speed of each telescopic element (base, carrier, slide) during the transfer process, ensuring that elements move at coordinated speeds to prevent collisions while maintaining efficient overall transfer speed.
Solution Approach 2:
The patent changes the transmission parameters by employing a transmission device with variable transmission ratios. Different transmission ratios are applied to different telescopic elements based on their position and functional requirements, allowing precise control over their relative speeds and positions throughout the transfer cycle, thereby preventing the carrier from moving ahead of the telescopic elements.
2Productivity
If telescopic elements are moved at different speeds to optimize transfer efficiency, then productivity increases, but coordination between elements becomes more complex, requiring precise control mechanisms
Solution Approach 1:
The patent merges the control of multiple telescopic elements into a single integrated transmission device driven by one motor. This transmission device simultaneously controls the base, carrier, and slide with different transmission ratios, eliminating the need for multiple independent motors and complex control systems while achieving coordinated movement and high transfer efficiency.
Solution Approach 2:
The transmission device serves multiple functions: it drives all telescopic elements (base, carrier, slide), provides different transmission ratios for each element, and ensures proper coordination throughout the transfer cycle. This multi-functional design simplifies the overall control system while maintaining high productivity.
3Manufacturing precision
If the carrier and telescopic elements move in sync with differential gear ratios, then precision and efficiency of component transfer is enhanced, but the transmission device complexity increases
Solution Approach 1:
The transmission device is segmented into multiple transmission stages, each with specific transmission ratios tailored to different telescopic elements. This segmentation allows precise control over the movement of each element (base, carrier, slide) while keeping each transmission stage relatively simple in design, balancing precision requirements with device complexity.
