Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport trolleys for material rolls in corrugated board plants are inflexible, complex, and expensive, leading to bottlenecks during width changes and limited usage due to serial processing, which increases costs and reduces efficiency.
Innovation Solution
A transport trolley with a self-supporting frame, multiple running units, a dedicated movement drive, and a communications device that receives external information for actuating movement, allowing for flexible and autonomous operation without fixed rails, enabling safe and efficient transport of material rolls with varying diameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If self-propelled transport trolleys are used to equip plants and machines during use, then transport flexibility is improved, but device complexity and cost increase significantly
Solution Approach 1:
The transport trolley is divided into modular components: a frame, multiple independent running units (at least three), and a communications device. Each running unit can be independently controlled, allowing the trolley to navigate complex paths while maintaining structural simplicity and reducing overall system complexity.
Solution Approach 2:
The trolley employs at least one movement drive connected to the frame that can dynamically adjust the position and orientation of running units based on received communications. This dynamic capability enables flexible navigation around obstacles and adaptation to varying transport requirements without requiring complex fixed infrastructure.
2Productivity
If multiple transport trolleys are used to process jobs simultaneously, then productivity increases, but mutual interference and bottlenecks occur in two-way traffic
Solution Approach 1:
The communications device with receiver unit enables real-time information exchange between multiple trolleys and the control system. This feedback mechanism allows trolleys to receive external information items about the positions and operations of other trolleys, enabling them to adjust their paths and operations to avoid conflicts and optimize overall system productivity.
3Reliability
If fixed rail systems are used for transporting material rolls, then transport path is stable, but flexibility and adaptability to varying roll sizes are reduced
Solution Approach 1:
The running units are designed to accommodate varying operational parameters including different material roll diameters and weights. The movement drive and control system can adjust operational parameters in real-time based on received communications, allowing the same trolley configuration to reliably transport various roll sizes without requiring fixed rail infrastructure.
