Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate facilities are used for manufacturing cores with organic binder and inorganic binder, then the manufacturing process can be specialized for each binder type, but the facility investment costs increase
Solution Approach 1:
The patent combines two separate core manufacturing facilities (one for organic binder and one for inorganic binder) into a single integrated facility. The system uses a common hopper, mixer, and molding equipment that can process both organic and inorganic binder materials through the same production line, thereby reducing facility investment costs while maintaining specialized manufacturing capabilities for each binder type
Solution Approach 2:
The core manufacturing facility is designed with universal equipment that can handle multiple binder types. The mixer and molding equipment are configured to accommodate both organic and inorganic binders, allowing a single facility to perform multiple functions and produce different types of cores using different binder materials
2Quantity of substance
If a single facility is used to manufacture both organic and inorganic core sand, then facility investment costs are reduced, but the system complexity increases
Solution Approach 1:
The system incorporates dynamic control mechanisms that allow the mixer and processing equipment to adapt their parameters based on the binder type being used. The facility can dynamically switch between processing organic and inorganic binders by adjusting mixing time, temperature, and other process parameters, thereby managing system complexity through flexible, adaptive control rather than requiring completely separate dedicated lines
3Reliability
If separate facilities are used for organic and inorganic binder processing, then cross-contamination is avoided, but productivity decreases due to duplication
Solution Approach 1:
The single facility is segmented into distinct processing zones or sequences for organic and inorganic binder handling. The system can process different binder types in separate batches or time sequences, preventing cross-contamination while utilizing the same equipment, thereby maintaining product purity without the need for duplicate facilities and improving overall productivity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The integrated system enables the production of both organic and inorganic core sand products in one facility, reducing facility investment costs and improving productivity.
Implementation Method 1
a mixer connected to the lower hopper to allow the first core sand to directly pass therethrough and accommodate the pure sand
Implementation Method 2
a binder supply unit connected to the mixer to supply an inorganic binder into the mixer
Implementation Method 3
a core mold that molds each of the first core sand that has directly passed through the mixer and second core sand in which the pure sand is coated with the inorganic binder in the mixer into a preset shape
