Solution Overview

Problem

Existing furnace systems face challenges in efficiently transporting saggars back to the inlet with fluctuating quantities without the need for complex control systems, particularly due to variable sawdust generation at the outlet.

Innovation Solution

A transport device with multiple parallel tracks allows for easy and continuous return transport of saggars to the oven inlet, adjusting the number of tracks used based on demand, using a single-speed operation and avoiding the need for complex control systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the transport speed of the return transport device is regulated based on the amount of saggar generated at the outlet, then the transport efficiency can be optimized, but a complex control system is required

Engineering Contradiction:
Improvetransport efficiencyVSAvoidcontrol system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The return transport device is divided into multiple independent parallel tracks instead of using a single track with variable speed control. Each track operates independently at constant speed, eliminating the need for complex centralized control systems while maintaining high transport efficiency through parallel processing capability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of dynamically adjusting the speed of a single transport device based on load conditions, the system uses a fixed number of parallel tracks that can be selectively activated. The system adapts to varying saggar quantities by utilizing different numbers of parallel tracks rather than changing the speed of individual tracks

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the transport device operates at variable speeds to handle fluctuating saggar quantities, then the system can adapt to demand, but the operational complexity increases

Engineering Contradiction:
Improveadaptability to fluctuating loadsVSAvoidoperational simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The transport system is segmented into multiple identical parallel tracks, each capable of operating independently at constant speed. This segmentation allows the system to adapt to fluctuating saggar quantities by activating the appropriate number of tracks, maintaining operational simplicity while achieving flexibility

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of changing the speed parameter of transport devices, the system changes the number of active parallel tracks. This parameter change approach maintains constant operating conditions for each track (simplifying operation) while adapting overall system capacity to match demand

Inventive Principle:
Principle #35Parameter changes
