Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a box mold with molding sand filling is used to support the core package, then the core package is externally supported and fixed, but operating costs increase due to the need for a box molding machine and multiple molds
Solution Approach 1:
The invention extracts the essential function of supporting and fixing the core package from the complex box mold system. Instead of using a complete box mold with molding sand filling, the patent applies clamping devices that directly clamp the core package at specific clamping points, removing the unnecessary mold structure while retaining the core support function.
Solution Approach 2:
The clamping device is designed to be universally applicable to different core packages. The adjustable clamping points and modular design allow the same clamping device to support various core package geometries and sizes, replacing the need for multiple specialized molds and achieving multi-functionality.
2Reliability
If the core package is adapted to the size of the mold, then the mold provides adequate support, but molding material consumption increases significantly when the product is smaller than the existing mold
Solution Approach 1:
Instead of requiring the entire mold to be sized for the largest possible core package, the invention applies clamping forces locally at specific clamping points on the core package. This localized approach provides adequate support without requiring excessive molding material to fill the entire mold cavity, reducing material consumption while maintaining support adequacy.
3Reliability
If multiple molds are used for continuous production of different products, then each product can be properly supported, but device complexity and cost increase due to mold replacement requirements
Solution Approach 1:
The clamping device incorporates adjustable clamping points and modular components that allow it to adapt to different core package geometries and sizes. This universal design enables a single clamping device to support multiple product types without requiring mold replacements, reducing device complexity while maintaining product-specific support adequacy.
Solution Approach 2:
The clamping device features adjustable and movable clamping points that can be dynamically repositioned according to the specific core package geometry. This dynamic adaptability allows the same device structure to provide optimal support for different products, eliminating the need for static, product-specific molds.
4Reliability
If the core package geometry deviates from a square or rectangular mold shape, then the mold must be oversized, but unusable areas increase and material efficiency decreases
Solution Approach 1:
The invention provides support only at the specific locations where clamping forces are needed on the core package, rather than requiring a complete mold structure that encompasses the entire core package volume. This localized support approach eliminates unusable material in irregular areas while maintaining adequate support for the core package geometry.
