Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ceramic refractory insulation blocks in hot presses crack and lose structural integrity over time, leading to increased operational costs and downtime due to the need for frequent replacements and associated deformation of expensive platen components.
Innovation Solution
Incorporating a plurality of reinforcing rods with greater flexural strength than the ceramic body, arranged in specific arrays to reduce cracking and crack propagation, thereby maintaining structural integrity and extending the lifespan of the insulation blocks and connected components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If ceramic refractory insulation blocks are used to support and insulate platens in a hot press, then insulation performance and platen support are improved, but structural integrity deteriorates over time due to cracking and propagation
Solution Approach 1:
The patent applies composite materials by combining ceramic refractory insulation blocks with reinforcing rods made of high-strength materials such as carbon fiber-reinforced polymer (CFRP), glass fiber-reinforced polymer (GFRP), or stainless steel. This composite structure allows the ceramic blocks to maintain their superior insulation properties while the reinforcing rods provide enhanced structural integrity and crack resistance, directly resolving the contradiction between insulation performance and structural strength.
Solution Approach 2:
The patent segments the ceramic refractory insulation block into multiple sections with reinforcing rods strategically positioned between these segments. The reinforcing rods act as internal partitions that divide the ceramic structure into smaller, more manageable segments, preventing crack propagation across the entire block while maintaining the overall insulation function.
2Reliability
If ceramic refractory insulation blocks are used in hot press operations, then insulation and support functions are achieved, but operational costs increase due to frequent replacements
Solution Approach 1:
The patent applies preliminary action by incorporating reinforcing rods into the ceramic refractory insulation blocks during the manufacturing process, before the blocks are installed in the hot press. This pre-reinforcement ensures that the blocks are structurally strengthened from the outset, preventing future cracking and eliminating the need for frequent replacements and associated downtime.
Solution Approach 2:
The reinforcing rods serve as a protective cushioning mechanism that is built into the ceramic blocks beforehand. This internal reinforcement structure absorbs and distributes stresses that would otherwise cause cracking, providing a buffer against the thermal and mechanical stresses encountered during hot press operations, thereby extending service life and reducing replacement frequency.
3Stability of the object's composition
If ceramic refractory insulation blocks support platens, then platen stability is maintained, but platen deformation occurs when blocks crack and lose integrity
Solution Approach 1:
By using composite materials consisting of ceramic blocks reinforced with high-strength rods, the patent creates a support structure that maintains its load-bearing capacity and structural integrity over time. This composite construction prevents the cracking that would otherwise cause platen instability and deformation, ensuring continuous platen stability and flatness throughout operational life.
4Strength
If reinforcing rods are added to ceramic refractory insulation blocks, then structural integrity and crack resistance are improved, but device complexity increases
Solution Approach 1:
The patent manages device complexity by segmenting the reinforcement strategy into discrete, modular reinforcing rods that are independently positioned within the ceramic blocks. This segmentation allows for standardized manufacturing processes and simplifies the integration of reinforcement elements, making the enhanced structural design more manageable despite the added complexity of multiple components.

AI summary
A ceramic refractory insulation block for a hot press (10) is provided that is reinforced in a manner that reduces the likelihood of cracking and, once cracked, reduces the rate at which the crack will propagate through the ceramic refractory insulation block. The ceramic refractory insulation block 18 includes a ceramic body 52 defining a plurality of outer surfaces 70, 72, 74. Each of the surfaces is a planar surface. The ceramic body 52 also defines a centerline 76 about which the ceramic body 52 is subjected to a bending moment 78. The ceramic refractory insulation body 52 also includes a plurality of reinforcing rods 54 extending through the ceramic body 52. The reinforcing rods 54 have a greater flexural strength than the ceramic body 52. One or more of the plurality of reinforcing rods 54 extend through the ceramic body 52 on each of the opposed sides of the centerline 76 about which the ceramic body 52 is subjected to the bending moment 78.
