Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If water-based cleaning systems are used to clean plastic waste, then cleaning function is provided, but energy consumption increases and water contamination occurs
Solution Approach 1:
The patent replaces water-based mechanical cleaning systems with a pneumatic sandsplash system. Compressed air carries abrasive blasting media (sand, gravel, or ceramic particles) to impact and clean plastic waste surfaces, eliminating the need for large volumes of water and high-energy drying processes while maintaining effective contaminant removal
Solution Approach 2:
The invention employs pneumatic principles to deliver cleaning force through compressed air flow. The pneumatic system transports abrasive blasting media through hoses and nozzles, using air pressure to propel particles that mechanically abrade contaminants from plastic surfaces without requiring water immersion or thermal drying
2Ease of manufacture
If water-based washing techniques are used, then cleaning function is provided, but water contamination increases
Solution Approach 1:
The patent substitutes water-based washing with a purely mechanical pneumatic abrasion system. Compressed air delivers abrasive particles that physically impact and remove contaminants from plastic surfaces, generating no wastewater, sludge, or water contamination while effectively cleaning the material
Solution Approach 2:
The pneumatic system uses compressed air as the transport medium instead of water. Air carries the abrasive blasting media through the system and dissipates into the atmosphere, leaving no liquid waste or water contamination behind, thus eliminating the harmful water contamination issue entirely
3Ease of manufacture
If traditional washing techniques are used to remove contaminants, then cleaning function is provided, but effectiveness in removing floatable and non-floatable contaminants is insufficient
Solution Approach 1:
The patent replaces water-based washing with pneumatic abrasive blasting that mechanically impacts all contaminant types. The high-velocity abrasive particles effectively remove both floatable contaminants (through impact) and non-floatable contaminants (through abrasion), providing reliable cleaning across all contaminant categories without relying on density-based separation
Solution Approach 2:
The pneumatic system delivers abrasive blasting media with sufficient kinetic energy to penetrate and remove various contaminant types. The compressed air flow ensures consistent delivery of abrasive particles that can effectively clean both floatable and non-floatable contaminants from plastic waste surfaces
4Device complexity
If a compact sandsplash system is designed, then device complexity is reduced, but cleaning power may be compromised
Solution Approach 1:
The patent employs a compact pneumatic system where a compressor generates compressed air that travels through hoses to reach blasting nozzles. This pneumatic delivery system maintains high cleaning power in a compact configuration, as the compressed air can be stored in a compact reservoir and delivered through flexible hoses to the cleaning point without requiring a large-scale mechanical structure
