Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a drive device is provided for each of multiple feed devices, then each table can be fed independently, but the configuration and control sequence become complex
Solution Approach 1:
The patent combines multiple drive devices into a single drive device that controls multiple feed devices. The interlocking mechanism couples the motion of multiple tables, allowing one drive device to synchronize the movement of multiple tables simultaneously, thereby reducing overall system complexity while maintaining independent feeding capability
Solution Approach 2:
The single drive device is designed to perform multiple functions by controlling different feed devices through the interlocking mechanism. This universal drive device can feed multiple tables in various sequences and patterns, replacing the need for dedicated drive devices for each table
2Measurement precision
If multiple drive devices are used for multiple feed devices, then each table can be controlled precisely, but the number of drive devices increases
Solution Approach 1:
Multiple drive devices are merged into a single drive device that controls multiple feed devices through an interlocking mechanism. This reduces the quantity of drive devices while maintaining positioning precision through the mechanical coupling that ensures synchronized and accurate movement of all tables
3Adaptability or versatility
If individual drive devices are provided for each feed device, then control flexibility is maintained, but manufacturing costs increase
Solution Approach 1:
The patent merges multiple drive devices into one, reducing component quantity and manufacturing cost. The interlocking mechanism enables this single drive device to maintain control flexibility by allowing various feeding sequences and patterns to be implemented through the mechanical coupling of multiple tables

AI summary
A robot system that simplifies a configuration and control sequence of a feed table device. The robot system includes a robot, a first table and a second table, a first feed device that feeds the first table, a second feed device that feeds the second table, an interlocking member that works the first feed device and the second feed device in synchronization with each other, and a control device that controls a first operation of the robot for a process and also controls a second operation, which is different from the first operation, of the robot for manipulating the interlocking member. The robot manipulates the interlocking member by the second operation, and thus respectively disposes the first table and the second table in a position corresponding to the process.
