Solution Overview

Problem

The precise positioning of mold components in ceramic die-casting processes is complex and requires significant engineering effort, especially in slip casting where porous plastic molds are used, as they can shift if not assembled correctly, leading to an improper seal and failed casting.

Innovation Solution

Integrating guides on mold carriers to ensure precise positioning of movable mold parts relative to each other, allowing for simplified assembly by guiding one mold carrier on another, reducing the need for precise force application and eliminating free positioning, thus simplifying the mold closure process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If precise positioning of mold components is achieved through complex engineering measures, then positioning accuracy is improved, but device complexity increases

Engineering Contradiction:
Improvepositioning accuracy of mold componentsVSAvoidengineering effort for positioning
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The mold assembly is divided into multiple mold carriers, each independently movable and equipped with guides. This segmentation allows each carrier to be positioned and guided separately, simplifying the overall positioning system while maintaining accuracy.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Guides are introduced as intermediary elements between mold carriers to enable precise positioning. These guides act as mediators that constrain movement paths and ensure accurate relative positioning without requiring complex engineering measures for direct carrier-to-carrier positioning.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If mold components are freely positionable for easy assembly, then ease of operation is improved, but positioning precision deteriorates

Engineering Contradiction:
Improveease of mold assemblyVSAvoidpositioning accuracy of mold components
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The mold carriers are designed to be dynamically movable during assembly and operation, guided by guide elements that provide constraint only when needed for positioning. This allows easy movement and assembly while ensuring precision when the mold is in operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The guides enable the mold carriers to self-position during assembly and operation. The carriers automatically find their correct positions through the guide constraints without requiring complex external positioning mechanisms or precise force application.

Inventive Principle:
Principle #25Self-service

3Productivity

If multiple mold carriers are used for complex mold assemblies, then manufacturing capability is improved, but device complexity increases

Engineering Contradiction:
Improvemanufacturing capability for complex componentsVSAvoidnumber of mold carriers and positioning mechanisms
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Each mold carrier is designed as a universal unit that can support different mold parts and includes integrated guides. This multi-functionality allows the same carrier design to be used throughout the assembly, reducing overall complexity despite having multiple carriers.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The guide elements are integrated within or attached to the mold carriers themselves, creating a nested structure where guides are part of the carrier assembly. This reduces the number of separate components and simplifies the overall device structure.

Inventive Principle:
Principle #7Nested doll (Nesting)
