Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current metal casting techniques are inefficient in material usage and prone to air bubble formation and oxidation due to the use of single pouring openings, which can lead to suboptimal joint formation between joinable components.
Innovation Solution
A bi-casting system with a movable pouring cup and platform within a vacuum chamber, allowing alignment with multiple surface openings to pour molten metal or alloy efficiently, reducing material usage and preventing air bubbles and oxidation by maintaining a vacuum during the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a single pouring opening is used in traditional metal casting, then the process is simple to operate, but material usage efficiency is poor and air bubbles form easily
Solution Approach 1:
The patent divides the single pouring opening into multiple pouring openings (first pouring opening and second pouring opening). This segmentation allows molten metal to be poured from multiple locations simultaneously, improving material utilization efficiency and reducing the formation of air bubbles by providing multiple escape paths for trapped gases during the casting process.
Solution Approach 2:
The patent combines multiple pouring operations into a single unified casting system where both pouring openings are integrated into the same mold structure. This merging allows simultaneous or sequential pouring from multiple openings while maintaining coordinated control over the casting process, improving efficiency without proportionally increasing operational complexity.
2Object-affected harmful factors
If a single pouring opening is used, then the equipment structure is simple, but oxidation and air bubble formation occur frequently
Solution Approach 1:
By segmenting the pouring system into multiple openings, the patent reduces the volume of air trapped above the molten metal and provides multiple pathways for air bubbles to escape during pouring. This segmentation effectively reduces oxidation and air bubble formation without requiring complex additional equipment.
Solution Approach 2:
The patent introduces a protective atmosphere system that fills the casting chamber with inert gas or maintains a controlled atmosphere environment. This creates an inert environment around the molten metal in the pouring cup and throughout the casting process, preventing oxidation and reducing air bubble formation by displacing oxygen and other reactive gases.
3Loss of substance
If multiple pouring openings are used, then material usage efficiency improves, but alignment precision requirements increase
Solution Approach 1:
The pouring cup is designed with multi-functionality to serve multiple pouring openings from a single reservoir. The cup structure includes multiple spouts or pouring lips that can simultaneously or sequentially deliver molten metal to different openings, reducing the need for multiple separate pouring operations and simplifying the alignment requirements while maintaining material efficiency.
Solution Approach 2:
The patent employs a movable or adjustable pouring cup mechanism that can dynamically position and orient the cup to align with different pouring openings as needed. This dynamic positioning capability allows the system to adapt to the specific geometry of multiple openings without requiring extremely tight fixed alignment tolerances, facilitating efficient material usage while managing alignment precision requirements.

Function Achieved in This Case
