Solution Overview

Problem

Handling and transportation of wet honeycomb ceramic bodies are prone to shape distortion and damage due to their soft state, requiring specific and costly carriers that are not universally applicable, leading to logistical complexities and potential deformation during drying processes.

Innovation Solution

A universal carrier system comprising a flexible sheet suspended between two side supports, which cradles the honeycomb body to minimize deformation and support it uniformly, eliminating the need for product-specific carriers and reducing point contact that can cause damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional rigid carriers are used to support wet honeycomb bodies, then structural support is provided, but shape distortion and damage occur due to point contact and lack of flexibility

Engineering Contradiction:
Improvesupport capabilityVSAvoidshape accuracy
Core Design Contradiction:
StrengthVSManufacturing precision

Solution Approach 1:

The patent employs a flexible sheet as the support surface instead of rigid carriers. This flexible sheet can conform to the honeycomb body's shape and provides distributed support across the entire surface, eliminating point contact damage while maintaining structural support during handling and drying processes

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The flexible sheet is suspended between side supports rather than being rigidly fixed, allowing it to dynamically adapt its shape to match the honeycomb body being supported. This dynamic flexibility enables the carrier to accommodate variations in honeycomb geometry without causing deformation

Inventive Principle:
Principle #15Dynamics

2Reliability

If product-specific carriers are designed for each honeycomb geometry, then optimal support is achieved, but device complexity and logistical burden increase

Engineering Contradiction:
Improvesupport effectivenessVSAvoidcarrier variety
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The flexible sheet carrier with adjustable side supports is designed to universally accommodate different honeycomb body geometries, sizes, and shapes. By adjusting the position and height of the side supports, the same carrier configuration can adapt to various product specifications, eliminating the need for multiple product-specific carriers

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

Solution Approach 2:

The carrier system is divided into modular components: the flexible sheet and adjustable side supports that can be independently positioned. This segmentation allows the carrier to be configured for different honeycomb geometries without requiring completely different carrier designs, reducing overall system complexity

Inventive Principle:
Principle #1Segmentation
