Solution Overview
Problem
Conventional data management systems for casting processes are limited in acquiring specific information, particularly for casting apparatuses that use gravity to pour molten metal and have tiltable molds, making it difficult to identify causes of defective products.
Innovation Solution
A data management system connected to casting equipment that includes a casting apparatus with tiltable molds, an engraving apparatus for product identifiers, and acquisition units for tilting patterns, temperature transitions, and imaging data, allowing for the association and storage of this information to identify defects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a gravity-based casting apparatus with tiltable molds is used, then the apparatus structure is simplified and cost is reduced, but specific information on tilting patterns and temperature transitions cannot be acquired, making defect cause identification difficult
Solution Approach 1:
The patent implements feedback by equipping the gravity-based casting apparatus with sensors that continuously monitor and record tilting patterns and temperature transitions during the casting process. This feedback mechanism captures critical process data that was previously unavailable, enabling defect analysis while maintaining the simplicity and low cost of the gravity-based system.
Solution Approach 2:
The patent replaces manual observation and mechanical measurement methods with electronic sensing and data acquisition systems. Sensors and controllers substitute for traditional mechanical gauges and manual recording, enabling automatic capture of tilting patterns and temperature transitions without complicating the overall apparatus structure.
2Reliability
If comprehensive data on tilting patterns and temperature transitions is collected and stored, then defect cause identification is improved, but the system complexity and data management burden increase
Solution Approach 1:
The patent introduces a controller as an intermediary device that automatically receives, stores, and manages data from multiple sensors. This controller acts as a mediator between the complex sensing network and the user, handling data organization and retrieval operations, thereby reducing the perceived system complexity for end users while maintaining comprehensive data collection for reliable defect analysis.
3Productivity
If the mold is tilted at higher speed to increase productivity, then pouring efficiency is improved, but air entrapment and oxide film formation increase, causing defects
Solution Approach 1:
The patent applies dynamics by enabling dynamic adjustment of the mold tilting speed during the pouring process. Rather than using a fixed high speed for all operations, the system can vary the tilting velocity based on real-time conditions, allowing optimization between productivity and defect prevention for different casting scenarios.
Solution Approach 2:
The patent uses feedback from sensors monitoring the casting process to detect early signs of air entrapment or oxide film formation. When such conditions are detected, the system can automatically adjust the tilting speed to prevent defects, creating a closed-loop control system that balances productivity with quality.
