Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the sand injection nozzle is made integral to the filling frame, then the structural strength is improved, but the maintenance difficulty increases and availability decreases
Solution Approach 1:
The sand injection nozzle is separated from the filling frame as a detachable component. This segmentation allows the nozzle to be replaced independently when worn, without replacing the entire filling frame, thus improving maintenance ease and availability while maintaining structural integrity through proper connection designs.
Solution Approach 2:
The sand injection nozzle is extracted as a separate replaceable component from the filling frame structure. This extraction enables independent maintenance of the nozzle, allowing quick replacement to restore machine availability without affecting the main filling frame structure.
2Ease of manufacture
If the filling frame is made as a single integrated component, then the manufacturing simplicity is improved, but the availability decreases when wear occurs
Solution Approach 1:
The filling frame system is segmented into the main filling frame structure and detachable components including the sand injection nozzle. This segmentation maintains manufacturing simplicity for each individual component while enabling quick replacement of worn parts, thus improving overall system availability and reliability.
3Ease of repair
If the liner is made detachable, then the ease of repair is improved, but the device complexity increases
Solution Approach 1:
The liner is designed as a detachable component that can be removed and replaced independently from the filling frame. This segmentation significantly improves ease of repair by allowing quick liner replacement without disassembling the entire filling frame, while the modular connection design minimizes the increase in device complexity.
Solution Approach 2:
The liner is designed as a consumable component that wears over time and can be replaced economically. By making the liner detachable and replaceable, the system allows for cost-effective maintenance by replacing only the worn liner rather than the entire filling frame, improving ease of repair while keeping the overall device complexity manageable.

AI summary
A molding machine forms a mold by using a transferred molding flask and pattern plate, and includes: a filling frame provided with a lower opening connectable to an upper opening of the molding flask and a side portion opened; a squeeze head mechanism including a squeeze board movable into and out from the filling frame, and a plurality of squeeze feet passing through the squeeze board, being able to move up and down with respect to the squeeze board; a sand injection hopper including at least one sand injection port for injecting molding sand into a molding space defined by the molding flask, the filling frame, the squeeze head mechanism, and the pattern plate; and a sand injection nozzle provided in a component detachably attached to an opening of the side portion of the filling frame to enable the sand injection port and the molding space to communicate with each other.
