Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If carriers are started at the same time to move together, then collision avoidance is improved, but production speed is reduced due to waiting time
Solution Approach 1:
The system dynamically adjusts carrier启动 timing based on real-time position detection and process requirements. Carriers can be started simultaneously when needed for synchronization, or individually when process conditions allow, optimizing both collision avoidance and production speed through adaptive control
Solution Approach 2:
The control device changes the timing parameter of carrier启动 based on detected positions and process requirements. By varying the启动 time parameter dynamically, the system achieves optimal balance between preventing collisions and maintaining high production speed
2Productivity
If carriers are started at different times to maintain production speed, then production speed is improved, but collision risk increases
Solution Approach 1:
The system continuously detects carrier positions and feeds this information back to the control device. Based on the feedback, the control device adjusts启动 timing to maintain safe distances between carriers, reducing collision risk while preserving production speed
Solution Approach 2:
The control device determines and prepares启动 timing for each carrier in advance based on predicted positions and process requirements. This preliminary planning allows carriers to be started at optimal times that prevent collisions while maintaining high production speed
3Adaptability or versatility
If additional hardware is added to enable simultaneous carrier control, then control flexibility is improved, but system cost increases
Solution Approach 1:
The control device is designed to perform multiple functions: it can control carriers individually or simultaneously, adjust启动 timing dynamically, and adapt to different process requirements. This multi-functionality eliminates the need for separate control systems, maintaining flexibility while avoiding additional hardware costs
Solution Approach 2:
The patent combines position detection, timing determination, and carrier control functions into a single integrated control device. By merging these functions, the system achieves high control flexibility without requiring separate hardware components for each function
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances flexibility and production speed by allowing carriers to move independently or in sync, reducing the risk of collisions and production costs by avoiding the need for additional hardware, thus optimizing the production process.
Implementation Method 1
carriers are conveyable by the use of magnetic force. The magnetic force can be produced by driving devices fixedly arranged in one or more tracks along which the carriers travel
