Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a negative pressure pump or suction blower is used to collect fiber waste, then fiber waste can be effectively suctioned and collected, but loud noise is generated which deteriorates the working environment
Solution Approach 1:
The patent extracts and removes the noise-generating components (negative pressure pump or suction blower) from the fiber waste collection system. Instead, it uses compressed air supply to create positive pressure that propels fiber waste through transfer pipes, eliminating the harmful noise while maintaining collection functionality
Solution Approach 2:
The patent applies pneumatic principles by using compressed air supply to create positive pressure in the transfer pipes, which propels fiber waste from suction ports to the collection container. This replaces the traditional negative pressure suction method with a positive pressure pneumatic transport system, achieving noise reduction while maintaining effectiveness
2Productivity
If compressed air is continuously supplied to transfer pipes, then fiber waste can be continuously transferred, but energy is wasted when suction ports are closed
Solution Approach 1:
The patent implements dynamic control of the compressed air supply system by linking the opening/closing state of compressed air supply valves to the opening/closing state of suction ports. This ensures compressed air is supplied only when fiber waste collection is actually occurring, eliminating energy waste during idle periods while maintaining continuous transfer capability when needed
Solution Approach 2:
The system incorporates feedback control where the state of suction ports (open/closed) provides information that automatically controls the compressed air supply valves. This feedback mechanism ensures energy is consumed only when necessary for actual fiber waste collection, optimizing energy efficiency
3Productivity
If multiple suction ports are arranged in parallel, then fiber waste from multiple locations can be collected simultaneously, but device complexity increases
Solution Approach 1:
The patent applies universality by using a single compressed air supply system that serves multiple suction ports arranged in parallel. The same positive pressure mechanism that propels fiber waste from one suction port works equally for all other suction ports, simplifying the overall system architecture while enabling multi-location collection
Solution Approach 2:
The patent segments the fiber waste collection system into multiple independent suction ports that can operate simultaneously, each connected to the common compressed air supply network. This segmentation allows parallel collection from multiple locations while the unified control approach prevents excessive complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution significantly reduces noise pollution and improves energy efficiency by using compressed air to collect fiber waste, preventing unnecessary air supply and minimizing energy loss, while effectively preventing backflow and clogging of transfer pipes.
Implementation Method 1
compressed air injected into the suction pipe from the compressed air injection nozzle hole of each of the plurality of suction units generates air flow capable of carrying the fiber waste toward a side of the fiber waste transfer pipe within the suction pipe
Implementation Method 2
each of the plurality of suction units further includes an opening/closing member for opening and closing the suction port
Implementation Method 3
the connection unit includes an opening/closing control valve to be opened and closed in a switchable manner between an opened state and a closed state thereby to control supply of compressed air toward the fiber waste transfer pipe
Implementation Method 4
the fiber waste having flown into the fiber waste transfer pipe from the suction port is transferred through the fiber waste transfer pipe with the aid of compressed air having flown from the connection unit
