Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual sweeping is used for snow removal, then labor intensity and time consumption increase, but sweeping efficiency remains low
Solution Approach 1:
The patent replaces manual mechanical sweeping with an automated snow removal system that uses a snow collecting device (spiral auger or snow shovel), snow throwing device (blower or impeller), and automated moving system with sensors and control modules to autonomously navigate and remove snow, dramatically improving productivity while reducing time consumption
Solution Approach 2:
The snow removal device is equipped with detection modules (ultrasonic sensors, infrared sensors, collision sensors) and control modules that enable the system to autonomously detect obstacles, navigate paths, and operate without continuous human intervention, achieving self-service operation that eliminates manual labor while maintaining high efficiency
2Productivity
If snow melting method using heat energy or chemical agents is used, then energy consumption increases and cost rises, but environmental pollution and road surface corrosion occur
Solution Approach 1:
The patent replaces thermal and chemical snow melting methods with a purely mechanical snow removal system that collects snow using a spiral auger or snow shovel and throws it aside using a blower or impeller, achieving effective snow removal without energy-intensive heating or harmful chemical agents, thus eliminating environmental pollution and road surface corrosion
Solution Approach 2:
The system extracts and removes snow from the road surface mechanically, separating the snow removal function from harmful thermal and chemical methods, allowing snow to be physically removed and discarded rather than melted or chemically treated, thereby avoiding pollution and corrosion
3Productivity
If large mechanical snow removal devices are used, then cost increases and snow removal effect deteriorates, but damage action to road surface occurs due to huge size
Solution Approach 1:
The patent segments the snow removal device into compact, modular components including a small prime motor, transmission device, snow collecting device, snow throwing device, and control modules, creating a compact system that is easy to maneuver on roads without causing damage, while maintaining effective snow removal capability
Solution Approach 2:
The system uses a small prime motor (electromotor or small engine) instead of large mechanical systems, combined with automated control and sensing technologies, to achieve effective snow removal with a compact device that minimizes road surface damage while reducing operational cost
4Ease of operation
If hand push operation is used to control snow blower, then labor intensity reduces, but automation degree remains low and manual operation is required
Solution Approach 1:
The snow removal device is equipped with detection modules (ultrasonic sensors, infrared sensors, collision sensors) and control modules that enable the system to autonomously detect obstacles, navigate paths, and operate without continuous human intervention, achieving self-service operation that eliminates manual labor while maintaining high efficiency
Solution Approach 2:
The patent replaces manual hand push operation with an automated moving system driven by a prime motor, combined with sensor-based obstacle detection and control modules that autonomously control movement and snow removal operations, dramatically increasing automation degree while reducing labor intensity
