Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
ImprovenoiseVSAvoidfiber waste collection efficiency
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

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

Inventive Principle:
Principle #2Taking out (Extraction)

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

Inventive Principle:
Principle #29Pneumatics and hydraulics

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

Engineering Contradiction:
Improvecontinuous fiber waste transferVSAvoidcompressed air energy waste
Core Design Contradiction:
ProductivityVSLoss of energy

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

Inventive Principle:
Principle #15Dynamics

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

Inventive Principle:
Principle #23Feedback

3Productivity

If multiple suction ports are arranged in parallel, then fiber waste from multiple locations can be collected simultaneously, but device complexity increases

Engineering Contradiction:
Improvemulti-location fiber waste collectionVSAvoidsuction pipe network complexity
Core Design Contradiction:
ProductivityVSDevice complexity

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Inventive Principle:
Principle #1Segmentation
