Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a suction device with a suctioning pipe and negative pressure pump is used to collect fiber waste, then fiber waste can be collected from the textile machine, but air accompanied with fiber waste is discharged to the exterior
Solution Approach 1:
The invention divides the collection system into separate functional components: a suctioning pipe for capturing fiber waste, a collection container for storing the waste, and a separate air discharge path that directs air through a filter before release. This segmentation allows the air and fiber waste to be handled separately, preventing direct discharge of air with fiber waste to the exterior while maintaining collection efficiency.
2Productivity
If the suction device operates continuously during yarn-threading or package-replacing, then fiber waste is collected effectively, but static electricity causes fiber waste to attach to the suctioning pipe
Solution Approach 1:
The invention introduces an intermediary element - a wire mesh or conductive coating - on the inner surface of the suctioning pipe. This intermediary conductive layer acts as a static discharge path, allowing accumulated static electricity to be dissipated continuously during operation. This prevents fiber waste from attaching to the pipe walls while enabling continuous collection during yarn-threading or package-replacing operations.
3Productivity
If the suctioning pipe diameter is increased to reduce air velocity and static electricity, then fiber waste collection is improved, but the device size and complexity increase
Solution Approach 1:
Instead of changing the physical dimensions of the suctioning pipe, the invention changes the electrical parameter by adding a conductive coating or wire mesh. This parameter change (adding conductivity) achieves the desired reduction in static electricity effects and improved fiber waste collection without increasing the pipe diameter or overall device size, thus avoiding increased complexity.
