Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the winding machine is stopped to replace the spool after winding is completed, then the spool can be replaced, but the winding efficiency is reduced
Solution Approach 1:
The patent implements continuous winding operation by preparing multiple spools in advance and enabling seamless spool replacement. The winding machine operates continuously without stopping, as spools are pre-positioned and swapped during non-critical moments or by auxiliary mechanisms, thereby eliminating idle time and maintaining uninterrupted productive action.
Solution Approach 2:
The patent applies preliminary action by preparing multiple spools beforehand and positioning them ready for immediate replacement. This advance preparation ensures that when a spool is depleted, a replacement is already in place, eliminating the need to stop the winding machine for spool changes and thus preventing loss of time.
2Productivity
If the winding machine is stopped to replace the spool, then the spool replacement can be performed, but the production efficiency is reduced
Solution Approach 1:
The patent maintains continuous production by implementing uninterrupted winding operation. Multiple spools are prepared in advance and replaced seamlessly, ensuring that the winding machine operates without stopping. This continuity eliminates downtime and maximizes production efficiency.
Solution Approach 2:
The patent uses preliminary action by preparing multiple spools before the winding process begins. These pre-prepared spools are positioned ready for immediate use, allowing rapid replacement without interrupting the winding operation, thus preventing production delays and maintaining high efficiency.
3Productivity
If multiple spools are prepared in advance for continuous winding, then winding efficiency is improved, but device complexity increases
Solution Approach 1:
The patent divides the spool management into independent, manageable segments. Multiple spools are prepared separately in advance, and the system handles them as discrete units. This segmentation simplifies the overall management by breaking down the complex task of continuous spool replacement into simpler, pre-prepared stages.
Solution Approach 2:
The patent reduces device complexity by performing spool preparation in advance rather than requiring complex real-time replacement mechanisms. By pre-positioning multiple spools and organizing them ready for use, the system avoids the need for sophisticated automated changeover equipment, thus maintaining simplicity while achieving continuous operation.
