Solution Overview

Problem

In the manufacturing of honeycomb structured bodies, continuous production lines are hindered by the need to halt all processes if a trouble arises in one stage, leading to decreased productivity and often resulting in the discard of immature products.

Innovation Solution

Implementing a method where treated honeycomb molded bodies are temporarily stored in a molded body storage container, allowing for compartmentalization of the production process without halting other stages, and using automated receiving and taking-out apparatuses to manage the storage and conveyance efficiently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a continuous production line is used for manufacturing honeycomb structured bodies, then productivity is improved, but if a trouble arises in one process stage, then all processes must be halted leading to productivity loss and waste of immature products

Engineering Contradiction:
ImproveproductivityVSAvoidproduction stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The production line is segmented into independent process stages (extrusion, drying, firing, coating) with buffer storage containers positioned between them. This segmentation allows each stage to operate independently, so that a failure in one stage does not propagate to halt the entire production line, thus maintaining productivity while improving reliability.

Inventive Principle:
Principle #1Segmentation

2Productivity

If all processes are synchronized in a continuous production line, then manufacturing efficiency is improved, but any disruption causes complete line halt and loss of immature products

Engineering Contradiction:
Improvemanufacturing efficiencyVSAvoidproduction line complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Buffer storage containers act as intermediaries between different process stages. These containers decouple the synchronization requirement, allowing each stage to operate at its own optimal pace while maintaining overall production flow. This reduces the complexity of coordinating all stages simultaneously while preserving manufacturing efficiency.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Speed

If the production line operates continuously without intermediate storage, then production speed is improved, but any process failure results in discard of immature products

Engineering Contradiction:
Improveproduction speedVSAvoidproduct waste
Core Design Contradiction:
SpeedVSLoss of substance

Solution Approach 1:

The buffer storage containers enable preliminary completion of products at one stage to be stored before proceeding to the next stage. This preliminary action allows immature products to be preserved in a stable state, preventing waste when subsequent stages experience disruptions, while maintaining high production speed throughout the line.

Inventive Principle:
Principle #10Preliminary action
