Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manufacturing processes for roll-type materials require manual loading and transportation, which can lead to damage, quality issues, and safety risks due to the heavy nature of the materials, necessitating an automated solution for loading, releasing, conveying, and inputting.
Innovation Solution
An automatic conveying and feeding facility that includes a roll buffer, transfer, and overhead hoist transport (OHT) with rod-to-rod movement, utilizing rods inserted into the roll-type materials and pusher units for automated handling, ensuring stable and efficient transfer between these components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual loading and transportation of roll-type materials is used, then device complexity is reduced, but manufacturing precision deteriorates due to damage and quality issues
Solution Approach 1:
The patent introduces an automated conveying facility as an intermediary system between storage and processing areas. This facility includes conveying mechanisms, transfer stations, and control systems that automatically handle roll-type materials, eliminating direct manual contact and transportation. The intermediary system ensures precise and damage-free material handling while maintaining operational efficiency.
2Reliability
If manual handling of heavy roll-type materials is performed, then device complexity is reduced, but reliability deteriorates due to safety risks and worker burden
Solution Approach 1:
The automated conveying facility enables self-service operation where the system automatically loads, conveys, and positions roll-type materials without human intervention. The facility includes automated transfer mechanisms, conveyors, and control systems that handle heavy materials safely and reliably, eliminating safety risks associated with manual handling while maintaining continuous operational reliability.
3Manufacturing precision
If automated conveying facility is introduced, then manufacturing precision is improved through automated handling, but device complexity increases
Solution Approach 1:
The conveying facility is divided into distinct functional segments including loading stations, conveying sections, transfer points, and unloading areas. Each segment performs a specific function and can be independently controlled or maintained. This segmentation allows for precise material handling in each zone while simplifying the overall system architecture and easing maintenance requirements.
4Productivity
If automated transfer and conveying systems are used, then productivity is improved through continuous operation, but device complexity increases
Solution Approach 1:
The conveying facility is designed to operate continuously without interruption, with materials being constantly loaded, conveyed, and transferred. The system includes multiple conveyors operating in sequence, automated transfer mechanisms that operate without stopping, and buffer storage areas that maintain continuous flow. This continuous operation maximizes productivity while the modular design keeps device complexity manageable through standardized components and procedures.
