Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If processing devices and cutting devices are fixed at predetermined positions, then device stability is improved, but the ability to manufacture linear materials of different lengths is worsened
Solution Approach 1:
The processing device and transport device are made movable along the transport direction, allowing their positions to be dynamically adjusted based on the required linear material length. The control device calculates optimal positions in each transport cycle and controls the devices to move to these calculated positions, enabling flexible production of different lengths while maintaining operational stability through controlled movement.
2Adaptability or versatility
If processing devices are repositioned to manufacture linear materials of different lengths, then product versatility is improved, but manufacturing process complexity is worsened
Solution Approach 1:
The control device implements a feedback control system that calculates the required processing device and transport device positions based on the target linear material length, controls the devices to move to these calculated positions, and adjusts their movements in each transport cycle according to the specific length requirements. This automated feedback control simplifies the manufacturing process by eliminating manual repositioning complexity.
3Manufacturing precision
If equipment is stopped to switch linear material types, then manufacturing precision is improved, but productivity is worsened
Solution Approach 1:
The processing device and transport device continuously operate without stopping to switch between different linear material types. The control device enables seamless transition by calculating and adjusting device positions in each transport cycle according to the required length, allowing the equipment to maintain continuous operation while producing linear materials of different lengths in accordance with a planned sequence, thus improving productivity without sacrificing manufacturing precision.
