Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical screw connections are used to attach mold frames to mold lifting cylinders, then the connection is secure and reliable, but the replacement process is time-consuming and expensive
Solution Approach 1:
The patent replaces the mechanical screw connection system with an electromagnetic fastening system. Electromagnets are integrated into the mold lifting cylinder, and corresponding ferromagnetic elements are attached to the mold frame. This substitution eliminates the need for manual screwing and unscrewing operations, reducing replacement time from minutes to seconds while maintaining secure connection during the pressing operation. The electromagnetic field can be activated/deactivated electrically to securely hold or quickly release the mold frame.
Solution Approach 2:
The patent changes the physical state of the connection from mechanical (threaded engagement) to electromagnetic (magnetic field interaction). By controlling the electrical current parameter to the electromagnets, the connection strength can be dynamically adjusted - fully engaged during pressing operations and quickly disengaged during replacements. This parameter change enables rapid tool-free attachment and detachment while maintaining connection reliability when needed.
2Reliability
If mechanical screw connections are used to attach mold frames to mold lifting cylinders, then the connection is secure, but the assembly process is expensive due to labor and time requirements
Solution Approach 1:
The electromagnetic fastening system replaces manual mechanical assembly operations with automated electromagnetic engagement. The electromagnets can be activated automatically when the mold frame approaches the lifting cylinder, eliminating the need for operators to manually position and tighten screws. This reduces labor costs and assembly time while maintaining secure connections, directly addressing the high manufacturing cost issue.
Solution Approach 2:
The electromagnetic system enables self-aligning and self-securing functionality. When the mold frame is positioned near the lifting cylinder, the electromagnetic field automatically engages the ferromagnetic elements without requiring precise manual alignment or operation of fastening mechanisms. This self-service capability reduces the skill level and time required for assembly operations, lowering manufacturing costs.
3Productivity
If electromagnetic fastening means are used to attach receiving devices to support devices, then the attachment is rapid and tool-free, but the device complexity increases due to integration of electromagnets
Solution Approach 1:
The patent merges the electromagnets directly into the structure of the mold lifting cylinder, combining the lifting function and the fastening function into a single integrated component. This eliminates the need for separate fastening mechanisms and reduces overall system complexity despite the addition of electromagnetic functionality. The control system is also integrated to manage both lifting and fastening operations through a unified interface.
