Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing transfer operations for reels in tire blank manufacturing are inefficient, leading to ergonomic issues, increased costs, and potential machine stoppages due to the limitations of autonomous mobile platforms when handling multiple mission instructions simultaneously.
Innovation Solution
A transfer installation with a control unit, independent mobile platforms, and measuring means to evaluate reel conditions, allowing for optimized mission instructions and minimizing the need for operator intervention by anticipating reel evacuation and supply needs, thus enhancing productivity and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If autonomous mobile platforms are used to transfer reels, then operator intervention is reduced and ergonomics are improved, but the system becomes inefficient when the number of mission instructions exceeds the number of available platforms
Solution Approach 1:
The system performs preliminary actions by measuring the quantity of product on reels in advance and using this data to determine optimal timing for evacuation and supply missions. This allows the control unit to transmit mission instructions proactively, ensuring platforms are dispatched at the most efficient moments rather than reacting to urgent needs, thereby maintaining high transfer efficiency with fewer platforms.
2Productivity
If the number of mobile platforms is increased to handle multiple missions simultaneously, then productivity is maintained, but the cost and size of the transfer installation increase
Solution Approach 1:
The system implements feedback by continuously measuring the quantity of product on reels and communicating this data to the control unit. This feedback loop enables the control unit to optimize mission timing and platform allocation dynamically, ensuring that the minimum necessary number of platforms is deployed while maintaining high transfer efficiency, thus avoiding the need for expensive and large-scale installations.
3Adaptability or versatility
If reel transfers are performed manually by operators, then flexibility is maintained, but the process is repetitive and lacks added value
Solution Approach 1:
The system enables self-service by automatically measuring reel product quantities, determining optimal transfer timing, and dispatching mobile platforms without continuous human intervention. The autonomous mobile platforms execute transfer operations independently based on control unit instructions, eliminating repetitive manual tasks while maintaining operational flexibility through programmable mission management.
