Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fixed workpiece lifting device is provided at a fixed position, then the device structure is simple, but the stacking area cannot be efficiently utilized and loading efficiency decreases when the stacking area is wide
Solution Approach 1:
The workpiece lifting device is made movable rather than fixed, allowing it to be repositioned to different locations in the stacking area. The control device determines optimal arrangement positions and orientations based on workpiece locations, enabling the lifting device to dynamically adapt to different stacking configurations and maximize loading efficiency.
Solution Approach 2:
The portable workpiece lifting device can serve multiple workpiece groups at different locations in the stacking area, rather than being dedicated to a single fixed position. This multi-functional capability allows one lifting device to replace multiple fixed devices, improving space utilization while maintaining loading efficiency.
2Productivity
If multiple workpiece lifting devices are arranged at multiple locations, then loading efficiency is improved, but it becomes difficult to accurately determine the arrangement position and orientation of portable devices
Solution Approach 1:
An image capturing device is introduced as an intermediary to detect the arrangement position and orientation of the portable workpiece lifting device. The control device processes the captured images to accurately determine the device's position and orientation, solving the measurement problem without requiring complex direct measurement systems on the lifting device itself.
Solution Approach 2:
The mechanical or manual method of determining device position and orientation is replaced with an optical detection system. The image capturing device captures visual information, and the control device processes this information to precisely determine arrangement parameters, achieving high measurement precision through optical-electrical conversion rather than mechanical measurement.
3Area of stationary object
If the stacking area is divided into multiple locations with different workpiece types, then space utilization is improved, but a fixed lifting device cannot handle multiple workpiece groups efficiently
Solution Approach 1:
The lifting device transitions from a fixed configuration to a movable, reconfigurable system. The control device calculates optimal arrangement positions and orientations based on the distribution of different workpiece types across the stacking area, enabling the lifting device to adapt to various workpiece groups and maximize space utilization.
Solution Approach 2:
The arrangement parameters (position and orientation) of the lifting device are made variable rather than fixed. The control device determines these parameters based on workpiece group locations and characteristics, allowing the device to change its configuration to handle different workpiece types efficiently across the divided stacking area.
