Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing linear conveyor system faces issues with transferring a slider between fixed and movable linear modules due to discontinuity in coordinate axes, preventing effective position control and transfer operations.
Innovation Solution
A linear conveyor system with a controller that sets and adjusts coordinate axes for fixed and movable linear modules, ensuring continuity by changing coordinate values, allowing for precise position control and transfer operations by generating a continuous coordinate axis system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If position control is executed based on coordinate axes set for respective fixed linear modules and movable linear module, then the transfer operation can be performed, but the coordinate axes are not continuous and the transfer operation cannot be performed
Solution Approach 1:
The system dynamically changes coordinate parameters by switching between local coordinate systems (for each linear module) and a unified coordinate system (spanning all modules) based on the operational state. When transferring between modules, the controller transitions from local coordinate control to unified coordinate control, ensuring continuous position representation across module boundaries without physical modification to the coordinate axes themselves
Solution Approach 2:
The coordinate system configuration is made dynamic rather than static. The system automatically adjusts which coordinate system is active based on whether the slider is being controlled by a single linear module or being transferred between modules. This dynamic switching resolves the discontinuity issue by adapting the coordinate representation to the current operational context
2Adaptability or versatility
If a movable linear module is used to transfer a slider between fixed linear modules, then flexibility in transfer operations is improved, but coordinate axis discontinuity prevents successful transfer
Solution Approach 1:
The unified coordinate system serves multiple functions: it provides continuous position measurement across all linear modules during normal operation, and it enables seamless transfer operations between modules by maintaining consistent position references. This universal coordinate framework allows the system to handle both individual module control and multi-module coordination with a single measurement system
Solution Approach 2:
The unified coordinate system acts as an intermediary layer between the local coordinate systems of individual linear modules and the overall transfer operation. During transfers, it mediates the position information from the movable linear module and the target fixed linear module, ensuring continuous and accurate position measurement throughout the transfer process

AI summary
A transfer operation of moving the slider between one fixed linear module and a movable linear module while locating the movable linear module in the facing range facing the one fixed linear module is performed. At this time, it is judged whether or not the coordinate axis of the one fixed linear module and the coordinate axis of the movable linear module are continuous If it is judged before the transfer operation that the coordinate axes are not continuous, the transfer operation is performed after the coordinate axes are made continuous in the direction by changing the coordinate axis. Thus, it is possible to suppress the occurrence of a situation where the transfer operation of moving the slider between the fixed linear module and the movable linear module cannot be performed due to the discontinuity of the coordinate axes respectively set for the fixed and movable linear modules.
