Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cam-based actuators are used in movable members, then the structure is simple and reliable, but the system lacks adaptability to changes in packaging material type and dimensions
Solution Approach 1:
The patent applies dynamics by replacing fixed cam-based actuators with motor-driven actuators that can dynamically adjust their movement profiles. The motors can be controlled to provide different motion patterns, speeds, and positions, enabling the movable members to adapt to various packaging material types and dimensions. This dynamic control capability allows the system to reconfigure itself for different packaging requirements without physical modifications.
Solution Approach 2:
The patent implements parameter changes by enabling continuous adjustment of actuator movement parameters such as position, speed, and acceleration through motor control. This allows the system to modify operational parameters in real-time based on the specific packaging requirements, achieving adaptability without changing the fundamental system structure. The motor-driven actuators can be programmed with different movement profiles to accommodate various packaging scenarios.
2Measurement precision
If real-time control and monitoring of movable members is implemented, then operational precision and error detection improve, but device complexity increases
Solution Approach 1:
The patent applies feedback by implementing monitoring systems that track the position, movement, and operational status of movable members in real-time. This feedback mechanism enables precise control by continuously comparing actual positions with target positions and making necessary adjustments. The feedback also facilitates error detection by identifying deviations from expected operational patterns, allowing for timely corrections and maintaining high measurement precision.
