Engineering Contradiction Analysis
1Use of energy by moving object
If dry coal particulate is used for gasification, then thermal efficiency is improved, but mechanical handling and pumping efficiency deteriorates
Solution Approach 1:
The coal plug is segmented into discrete sections by the chain links as it moves through the posimetric rotary drive. Each chain link creates a defined segment of coal material, allowing for controlled handling and pumping of dry coal particulate while maintaining thermal efficiency benefits.
Solution Approach 2:
The posimetric rotary drive with its integral chain acts as an intermediary mechanism between the dry coal particulate and the pumping system. This intermediary structure enables efficient mechanical handling by providing a working surface that interacts with the coal plug, solving the mechanical handling efficiency problem while preserving thermal efficiency.
2Productivity
If a posimetric rotary drive with integral chain is used, then pumping capacity is improved, but device complexity increases
Solution Approach 1:
The chain is made integral with the hub, merging two separate components (chain and hub) into a single unified structure. This reduces the number of separate parts that need to be assembled and maintained, thereby reducing device complexity while still providing the necessary pumping capacity through the posimetric rotary drive mechanism.
Solution Approach 2:
The hub serves multiple functions: it supports the chain, provides structural integrity to the posimetric rotary drive, and acts as part of the driving mechanism. This multi-functionality reduces the need for additional separate components, simplifying the overall device structure while maintaining high pumping capacity.
