Innovation Solution
A modular mold structure with displaceable molded parts and insert devices allows for varying cavity volumes and shapes, enabling the production of diverse objects with different geometries using a single mold setup, including magnetic attachment for ease of assembly and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional two-piece mold structure is used, then mold strength and sealing are improved, but adaptability and productivity deteriorate due to inability to produce different geometries
Solution Approach 1:
The mold is divided into multiple detachable connecting mold parts that can be independently positioned and removed. These segmented parts allow the cavity geometry to be reconfigured for different products while maintaining the overall mold structure integrity.
Solution Approach 2:
The connecting mold parts are designed to be movable and repositionable rather than fixed. This dynamic structure enables the mold to adapt to different cavity geometries by adjusting the position and configuration of the connecting parts between molding operations.
2Manufacturing precision
If custom molds are produced for each object geometry, then manufacturing precision is improved, but loss of time and device complexity worsen
Solution Approach 1:
The mold base structure, including the cavity definition and connecting part interfaces, is prepared in advance. This preliminary preparation allows quick exchange of connecting mold parts without requiring complete mold remanufacturing, reducing lead time while maintaining precision.
Solution Approach 2:
A single mold base structure is designed to perform multiple functions by accommodating different connecting mold parts. This universal mold can produce various geometries by simply changing the connecting parts, eliminating the need for custom molds for each product.
3Device complexity
If fixed mold geometry is used, then device complexity is reduced, but adaptability deteriorates due to inability to produce different objects
Solution Approach 1:
The mold structure is segmented into standardized base components and interchangeable connecting parts. This segmentation maintains relative simplicity of individual components while enabling high adaptability through reconfiguration of the connecting parts for different products.
