Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the processing speed is increased to improve productivity, then the hourly output increases, but liquid sloshing and spillage occurs during filling and sealing processes
Solution Approach 1:
The patent applies dynamics by implementing adjustable motion profiles that dynamically control the reciprocating beams' acceleration and deceleration rates. The system can adapt the speed characteristics based on the pouch type and liquid viscosity, allowing high productivity while preventing liquid sloshing through optimized dynamic parameters.
Solution Approach 2:
The patent changes physical parameters by implementing variable acceleration and deceleration rates for the reciprocating beams. Different motion profiles with specific acceleration/deceleration parameters are selected based on pouch dimensions and liquid properties, enabling the system to maintain high speed operation without causing liquid spillage.
2Productivity
If the reciprocating beam speed is increased to improve processing efficiency, then the cycle time decreases, but the alignment precision of pouches with stations deteriorates
Solution Approach 1:
The patent applies periodic action through the reciprocating motion of the beams, which move back and forth in a controlled cycle. The motion profile is designed with specific acceleration, constant velocity, and deceleration phases that ensure pouches are properly positioned at each station during the periodic cycle, maintaining alignment precision while achieving high processing efficiency.
3Device complexity
If a fixed motion profile is used to simplify the control system, then the device complexity is reduced, but the adaptability to various pouch dimensions and shapes is limited
Solution Approach 1:
The system uses dynamic motion profiles that can be adjusted based on pouch characteristics. The controller selects appropriate acceleration and deceleration parameters from a library of predefined profiles, allowing the system to adapt to different pouch types without requiring complex real-time calculations, thus maintaining relatively simple device architecture while achieving high versatility.
