Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a linear drive is used to move the container along a trajectory curve, then the container can be driven in a positively guided reciprocating motion, but the device complexity increases and linear guides or slotted guides are required
Solution Approach 1:
The patent replaces the linear drive system with a rotary drive system. The container holder is driven by rotary motors that generate rotational motion, which is then converted to reciprocating motion through a linkage mechanism consisting of levers and pivot bearings. This substitution eliminates the need for linear drives and linear guides, reducing device complexity while maintaining reliable guided motion.
Solution Approach 2:
The patent employs curved trajectories for the container holder's motion path. The rotary drives move the container holder along arc-shaped or sinusoidal trajectories rather than straight linear paths. This curved motion approach allows the system to achieve complex reciprocating patterns using only rotary actuators, avoiding the need for linear guidance mechanisms.
2Device complexity
If rotary drives are used instead of linear drives, then the device complexity is reduced, but achieving precise trajectory guidance becomes more difficult
Solution Approach 1:
The patent uses a dynamic linkage mechanism with multiple levers and pivot bearings that convert rotary motion into precise reciprocating motion along curved trajectories. The mechanism includes a first lever with a first pivot bearing, a second lever with a second pivot bearing, and a container holder that moves along a predetermined trajectory. The dynamic interaction between these components ensures accurate trajectory guidance while maintaining device simplicity.
Solution Approach 2:
The patent introduces intermediate linkage components (levers and pivot bearings) that mediate between the rotary drives and the container holder. These intermediaries transform the simple rotary motion into complex reciprocating trajectories with high precision. The linkage mechanism acts as a mechanical intermediary that translates rotational input into the desired curved motion path without requiring complex control systems.
