Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing material sorting systems are inflexible and inefficient, particularly when handling multi-carrier systems, autonomous mobile transport systems, or robots, as they struggle to accurately capture and process data from multiple sensors at different points in the production process, leading to complex interactions and high data loads that overwhelm existing infrastructure.
Innovation Solution
A control system that incorporates an edge computing device to determine time information and transport times, allowing for real-time control of handling components and enabling flexibility and adaptability across various transport systems by decoupling time information determination from the control device, thereby simplifying real-time control and reducing data processing burdens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an integrated control device processes all sensor data in real-time, then measurement precision and response time are improved, but device complexity and data processing load increase significantly
Solution Approach 1:
The system divides the control infrastructure into two segments: an edge computing device that determines time information from sensor data, and a control device that executes real-time control programs. This segmentation allows the control device to focus only on real-time control execution while the edge device handles time information determination, reducing the control device's data processing load and complexity.
Solution Approach 2:
The edge computing device acts as an intermediary between the sensor components and the control device. It processes sensor data to determine time information and provides this processed information to the control device, which then uses it for real-time control decisions. This intermediary approach simplifies the control device's workload while maintaining measurement precision.
2Adaptability or versatility
If the control system is highly integrated with all functions in one device, then adaptability to different transport systems is reduced, but ease of operation is improved
Solution Approach 1:
The control system is segmented into independent functional units: the edge computing device that determines time information and the control device that executes control programs. This modular architecture allows the system to be adapted to different transport systems (conveyor belts, multi-carrier systems, autonomous mobile transport systems, robots) by configuring the appropriate sensor components and control programs without redesigning the entire system.
3Speed
If time information determination is integrated into the control device, then real-time control performance is improved, but adaptability to changed transport parameters is reduced
Solution Approach 1:
The system separates time information determination (edge computing device) from real-time control execution (control device). The edge computing device can determine time information using various methods suitable for different transport systems, while the control device executes real-time control programs based on this information. This segmentation maintains real-time control performance while allowing flexibility in how time information is determined for different transport parameters.

AI summary
A control system for handling a processing product includes a control device with at least one application module for interconnecting first and second sensor components, and a control module, wherein the first and second sensor components capture first and second sensor data, the handling component handles, processes and/or manipulates the processing product, and the control module executes the control program, and further includes an edge computing device which determines an item of time information, where times for transporting a product transported on the transport device from the first to the second sensor component and on to the handling component are determined from the item of time information, and wherein the control module executes the control program to provide real-time control of the handling component for handling the processing product taking into account the first and second sensor data and the time information and/or the determined transport times.
