Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional collection methods are used, then the collection process is simple, but the orientation and uniformity of carbon nanotube macroscopic bodies are poor
Solution Approach 1:
The patent applies preliminary action by introducing a pre-adjustment mechanism before the main collection process. This mechanism includes first and second wheel bodies that pre-press and align the carbon nanotube aggregates in a first direction, and a third wheel body that draws and aligns them in a second direction. This preliminary orientation adjustment ensures that the carbon nanotubes are properly aligned before being wound into the final macroscopic body, thereby improving orientation and uniformity without complicating the main collection function.
Solution Approach 2:
The patent segments the collection device into distinct functional modules: a pre-adjustment mechanism with multiple wheel bodies for orientation control, and a winding mechanism for collection. The pre-adjustment mechanism is further divided into first and second sub-mechanisms that operate in sequence. This segmentation allows each component to perform its specific function efficiently while maintaining overall system clarity and manageability.
2Stability of the object's composition
If pre-adjustment mechanisms are added to improve orientation, then the internal structure and orientation of carbon nanotubes are improved, but the device complexity increases
Solution Approach 1:
The pre-adjustment mechanism performs preliminary orientation alignment before the main winding process. The first wheel bodies pre-press aggregates in a first direction, the third wheel body draws and aligns them in a second direction, and the fourth wheel body provides additional drawing force. This sequential preliminary action ensures proper internal structure formation without requiring complex adjustments during the main collection process.
Solution Approach 2:
The wheel bodies act as intermediary elements that transfer and control the orientation of carbon nanotube aggregates. These intermediary components enable precise control over the internal structure through mechanical interaction, serving as mediators between the raw aggregates and the final organized macroscopic body.
3Manufacturing precision
If multiple wheel bodies are used for pre-adjustment, then orientation control is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The multiple wheel bodies are arranged to perform preliminary orientation actions in a fixed sequence. The first wheel bodies pre-press, the third wheel body draws and aligns, and the fourth wheel body provides additional drawing force. This predetermined sequence simplifies operation by eliminating the need for complex real-time adjustments, as each component automatically performs its specific orientation function in order.
Solution Approach 2:
The patent merges multiple orientation-control functions into a single integrated pre-adjustment mechanism section. The first and second wheel bodies, third wheel body, and fourth wheel body work together as a unified system that simultaneously performs pre-pressing, alignment, and drawing functions, reducing the complexity of coordinating separate operations.
