Solution Overview

Problem

The production of ceramic cast parts using traditional slip casting molds is complex and time-consuming due to inefficient dewatering processes, limiting the flexibility and speed of transporting the green compact.

Innovation Solution

A slip casting mold design featuring a first mold part with a base body and filtration layer, where water is drained through a dewatering channel that opens into a dewatering channel within a second mold part or an additional dewatering body, allowing for free movement and flexible transport of the mold part, facilitated by a robot-assisted fluid supply and discharge system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If water is drained through a connection to the base body via flexible hoses, then the mold parts can move relative to each other, but the transport of the green compact is limited and the process becomes complex

Engineering Contradiction:

Improveflexibility of transportVSAvoidcomplexity of dewatering process

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The dewatering channels of the first and second mold parts are merged into a single integrated channel structure. The first dewatering channel opens directly into the second dewatering channel, eliminating the need for separate flexible hose connections and reducing overall system complexity while maintaining transport flexibility.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The second mold part acts as an intermediary element that receives water from the first mold part's dewatering channel and facilitates its discharge. This intermediary structure enables the first mold part to move freely without direct hose connections while ensuring effective water drainage.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the first mold part is connected to a drain via flexible hoses, then water can be drained, but the first mold part cannot move freely after dewatering

Engineering Contradiction:

Improvefree movement of mold partVSAvoidspeed of transport

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The flexible hose connection is extracted and replaced by a direct integration of dewatering channels within the mold parts themselves. This removes the constraint that prevented free movement while maintaining the drainage function through the integrated channel structure.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The dewatering channel system is designed to remain functional during the movement and transport phases. The first dewatering channel's opening into the second dewatering channel maintains drainage capability regardless of the mold parts' position or movement state, enabling dynamic operation throughout the process.

Inventive Principle:

Principle #15Dynamics

3Productivity

If traditional slip casting molds are used with separate dewatering connections, then the structure is simple, but the production process is time-consuming

Engineering Contradiction:

Improvespeed of productionVSAvoidtime for dewatering process

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The dewatering process continues seamlessly as water flows directly from the first mold part's filtration layer through its dewatering channel into the second mold part's dewatering channel without interruption or manual intervention. This continuous action eliminates delays associated with hose connections and manual drainage operations.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The dewatering channels are pre-configured within the mold parts during manufacturing, so that when the casting process begins, water can immediately drain through the integrated channels without requiring additional setup or connection steps. This preliminary preparation accelerates the overall production cycle.

Inventive Principle:

Principle #10Preliminary action
