Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If workers manually mix and add resin solution, then flexibility in operation is maintained, but labor intensity increases and continuous production is hindered
Solution Approach 1:
The resin stirring bath is equipped with an automatic stirring mechanism that continuously mixes the resin solution without human intervention. The system self-regulates the mixing process, eliminating the need for workers to manually mix and transfer resin, thereby reducing labor intensity while enabling continuous production.
Solution Approach 2:
The patent replaces manual mechanical operations with an automated stirring mechanism. The mechanical stirrer is driven by a motor to continuously mix the resin solution, substituting human labor with an automated mechanical system that operates without interruption.
2Temperature
If low-precision water bath heating is used, then equipment complexity is reduced, but temperature control precision deteriorates leading to heat loss
Solution Approach 1:
The patent implements localized heating zones: the resin impregnation bath has heating elements positioned specifically to maintain temperature where fiber impregnation occurs, and the pressure roller includes internal heating to compensate for heat loss during the winding process. This targeted approach ensures temperature stability at critical locations without requiring complex system-wide temperature control.
Solution Approach 2:
The heating system incorporates temperature sensors that continuously monitor the resin solution temperature and provide feedback to the control system. Based on this feedback, the heating power is automatically adjusted to maintain the desired temperature, preventing both heat loss and overheating while managing system complexity through intelligent control.
3Temperature
If resin solution is heated and then allowed to cool during transfer, then heating energy is saved, but temperature at impregnation position drops below technological requirements
Solution Approach 1:
The heating action continues throughout the entire process rather than being applied only during bulk heating. The resin impregnation bath maintains heating during transfer, and the pressure roller provides continuous auxiliary heating during winding. This continuous heating ensures the resin solution temperature remains within technological requirements throughout all stages, preventing temperature drop without excessive energy consumption.
Solution Approach 2:
The resin solution is pre-heated to the required temperature before impregnation begins. The resin impregnation bath and pressure roller are pre-heated in advance to ensure that when the resin solution contacts the fiber and undergoes impregnation, the temperature is already optimal and maintained throughout the process.
4Stability of the object's composition
If manual mixing is used, then equipment simplicity is maintained, but mixing uniformity and resin content consistency deteriorate
Solution Approach 1:
The patent replaces manual mixing with an automated mechanical stirring mechanism equipped with multiple stirring blades. This mechanical system provides consistent, controlled mixing action that ensures uniform resin content distribution throughout the solution, achieving stable composition that cannot be reliably obtained through manual mixing.
Solution Approach 2:
The resin solution is thoroughly mixed and made uniform in composition before the impregnation process begins. The stirring mechanism operates in advance to ensure complete homogenization of the resin and curing agent, creating a consistently uniform mixture that maintains its composition stability throughout subsequent processing stages.
