Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If weight scales are used to measure waste yarn, then measurement accuracy is improved, but device complexity and time consumption increase
Solution Approach 1:
The patent replaces mechanical weight measurement systems with a computational model that calculates waste yarn amount based on rotational angles and operational parameters. The output section computes waste yarn emission amounts by integrating rotation angles of the winding drum and package during yarn joining operations, eliminating the need for physical weight scales and manual measurement procedures.
Solution Approach 2:
The patent introduces rotational angle data as an intermediary parameter to indirectly measure waste yarn amount. Instead of directly weighing waste yarn, the system measures the rotation angles of the winding drum and package, then uses these angular measurements as intermediate values to calculate the equivalent waste yarn emission amount through computational integration.
2Measurement precision
If manual weight measurement is used, then measurement accuracy is improved, but productivity and time efficiency deteriorate
Solution Approach 1:
The patent implements continuous measurement and calculation of waste yarn emission amounts during textile machine operation. The system continuously monitors rotational angles of the winding drum and package, and the output section continuously computes waste yarn emission amounts based on these real-time angular measurements, enabling ongoing productivity assessment without interrupting the manufacturing process for manual weighing.
Solution Approach 2:
The patent replaces time-consuming manual weight measurement with automated computational calculation based on rotational angle integration. The system processes angular data through mathematical integration to directly obtain waste yarn emission amounts, eliminating the need to stop production for manual measurement and significantly improving information acquisition speed while maintaining measurement accuracy.
3Productivity
If rotation angle calculation is used, then productivity is improved, but measurement precision may deteriorate
Solution Approach 1:
The patent uses rotational angle as an intermediary physical quantity that can be measured with high precision by encoders or sensors. These angular measurements serve as accurate intermediate parameters that are then integrated computationally to determine waste yarn emission amounts, maintaining measurement precision while enabling continuous real-time calculation without manual intervention.
Solution Approach 2:
The patent changes the measurement parameter from direct weight measurement to rotational angle measurement. By measuring angular displacement of the winding drum and package during yarn joining operations and integrating these angular parameters, the system achieves both high productivity through automated calculation and maintained precision through accurate angular sensing and mathematical integration.
