Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If wet-type recycling method is used, then paper recycling can be achieved, but huge amount of water is required and energy consumption is large
Solution Approach 1:
The invention extracts and eliminates the water-based processing step from the recycling process. By using a defibrator that operates without water, the system achieves paper recycling while removing the need for huge water quantities and subsequent drying energy consumption, directly resolving the contradiction between water usage and energy loss
Solution Approach 2:
The invention replaces the mechanical water-based defibration system with a pneumatic system using a defibrator. This substitution eliminates the need for water immersion and mechanical pressing, achieving fiber separation through air flow and centrifugal force, thereby reducing both water consumption and energy requirements
2Productivity
If large-scale recycling facilities are installed, then quantity requirements for recycling can be satisfied, but facility complexity and cost increase
Solution Approach 1:
The invention segments the recycling process into a compact, modular defibrator unit that can be installed in small offices. By dividing the function into a portable defibration device rather than requiring a large-scale facility, the system achieves sufficient recycling capacity for office environments while dramatically reducing facility complexity and installation requirements
3Quantity of substance
If dry-type defibration technique is used, then water consumption is reduced, but airflow force is not constant due to temperature fluctuations
Solution Approach 1:
The invention introduces a feedback control system where temperature sensors monitor the defibrator interior temperature and the control unit adjusts the rotor rotation speed accordingly. This feedback mechanism compensates for temperature-induced airflow fluctuations, maintaining constant airflow force while preserving the water-free processing advantage
Solution Approach 2:
The invention makes the rotor rotation speed adjustable and dynamic rather than fixed. By allowing the control unit to vary the rotation speed in response to temperature changes, the system adapts to maintain optimal airflow conditions, resolving the contradiction between water reduction and airflow stability
4Ease of operation
If small office recycling is implemented, then self-recycling and security are improved, but quantity requirements for recycling cannot be met
Solution Approach 1:
The invention segments the recycling function into a compact, office-sized defibrator that can be deployed in small offices. This segmentation allows individual offices to perform self-recycling of their waste paper, meeting security requirements while the device's optimized design ensures it can handle sufficient quantities for practical office recycling needs

Implementation Method 1
a defibration unit that pulverizes and defibrates a raw sheet material that contains fibers
Implementation Method 2
the force of transporting the waste paper as a material by the airflow is not constant because the density of air fluctuates depending on the temperature
