Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Packaging systems with robots are limited in their flexibility and utility, as they are often restricted by size and force capabilities, and require complex cabling that complicates maintenance and hygiene.
Innovation Solution
A packaging system with a robot mounted on a transport carriage that includes a frame, current collector, and various operating components such as a data transmission device, drive, compressor, and vacuum pump, allowing wireless operation and movement along the packaging machine, eliminating the need for a drag chain and enhancing flexibility and hygiene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If robots are used to support system operations such as format changes, then operational flexibility is improved, but safety limitations restrict robot dimensions and force absorption capabilities
Solution Approach 1:
The patent introduces a collaborative robot that acts as an intermediary between the packaging system and operators. This mediator robot performs auxiliary tasks like format changes and consumable management, enabling operational flexibility while maintaining safety through controlled interaction capabilities and limited force absorption designed for collaborative work environments.
2Reliability
If traditional cabling systems are used to power and control moving robots, then reliable power transmission is achieved, but system complexity and maintenance requirements increase
Solution Approach 1:
The patent replaces the mechanical cabling system with a wireless power and data transmission system. The moving robot communicates with and receives power wirelessly from stationary components, eliminating the need for drag chains and physical cables, thereby reducing system complexity and maintenance requirements while maintaining reliable power transmission.
3Stability of the object's composition
If drag chains are used to supply power and signals to moving components, then continuous connection is maintained, but hygiene requirements cannot be met due to difficult-to-clean structures
Solution Approach 1:
The patent eliminates drag chains by implementing wireless power and data transmission. This substitution removes the mechanical connection system that creates hygiene problems, allowing the robot and surrounding areas to meet stringent hygiene requirements while maintaining continuous power and communication connections through wireless means.
4Reliability
If robots are limited in size and force for safety, then operator safety is improved, but the range of applicable tasks is reduced
Solution Approach 1:
The patent designs a universal collaborative robot platform that can perform multiple functions including format changes, consumable management, and auxiliary packaging tasks. By making the robot multi-functional and adaptable to various operations, it expands the range of applicable tasks while maintaining safety through collaborative design principles that limit force and size appropriate for human-robot interaction.
