Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machines for compacting ceramic powder to produce structured ceramic articles face issues with frequent wear of the pressure belt, leading to inferior quality slabs and increased production costs due to the need for frequent replacements and non-homogeneous slab quality.
Innovation Solution
A machine with a pressure belt featuring a metal or composite base layer and a polymer contact layer with a structured surface, equipped with an identification code and a control unit to monitor wear, allowing for timely replacement and adjustment of the contact layer to maintain consistent quality and reduce waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a pressure belt with a structured contact surface is used to compact powder material, then a structured surface on ceramic articles is obtained, but the contact surface is subject to progressive wear and must be replaced at frequent intervals
Solution Approach 1:
The pressure belt is segmented into a base layer and a replaceable contact layer. The contact layer can be removed and replaced when worn, while the base layer remains in use. This segmentation allows the structured surface function to be maintained by replacing only the worn contact layer rather than the entire pressure belt.
Solution Approach 2:
The contact layer is designed to be discarded when worn and recovered (reused) by transferring it to a new base layer. The method includes removing the contact layer from a worn base layer and transferring it to a new base layer, thereby extending the service life of the structured contact surface.
2Manufacturing precision
If the contact layer material is chosen for its ability to create structured surface, then the desired relief geometry is achieved, but the material is relatively prone to wear
Solution Approach 1:
The pressure belt is divided into a base layer and a contact layer with different material properties. The base layer provides structural support and durability, while the contact layer provides the structured surface geometry. This segmentation allows each layer to be optimized for its specific function.
Solution Approach 2:
The pressure belt uses a composite structure combining a base layer (which can be metal, composite, or fabric) with a contact layer made of plastic material. This composite construction allows the system to benefit from both the structural properties of the base layer and the surface properties of the contact layer.
3Productivity
If the structured contact surface is used continuously, then production efficiency is maintained, but the quality of slabs becomes non-homogeneous as wear progresses
Solution Approach 1:
The system uses an identification code on the base layer and a detection device to track the service life of each base layer. When the contact layer is removed from a worn base layer, the detection device reads the identification code to determine how many times the base layer has been used, providing feedback to control the replacement process.
Solution Approach 2:
The method allows the contact layer to be pre-transferred to a new base layer before the worn base layer is discarded. This preliminary action ensures that a fresh contact layer is already prepared on a new base layer, allowing continuous operation without interruption and maintaining quality homogeneity.
4Manufacturing precision
If the entire pressure belt is replaced when wear occurs, then quality issues are resolved, but production time is lost and costs increase
Solution Approach 1:
By segmenting the pressure belt into replaceable contact layer and permanent base layer, the system allows replacement of only the worn contact layer rather than the entire pressure belt. This significantly reduces replacement time and maintains continuous production.
Solution Approach 2:
The base layer is recovered and reused by transferring the contact layer from a worn base layer to a new base layer. This recovery process eliminates the need to discard and replace the entire pressure belt, reducing both time and cost.
