Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mechanical snow removal devices are used, then snow removal efficiency is improved, but device complexity and cost increase
Solution Approach 1:
The snow removal device is divided into functional modules: a working module for snow collection and removal, a moving module for autonomous navigation, an energy module for power supply, a detection module for environmental sensing, and a control module for coordination. This segmentation allows each module to be optimized independently while maintaining overall system efficiency.
Solution Approach 2:
The device integrates multiple functions into a single autonomous system that can navigate, detect environmental conditions, collect snow, throw snow, and manage its own energy supply. This multi-functionality improves snow removal efficiency while avoiding the need for multiple separate complex devices.
2Productivity
If traditional mechanical snow blowers are used, then snow removal capability is improved, but harm to road surface increases
Solution Approach 1:
The working module uses a snow collecting wheel with optimized rotational speed (smaller than 100 rpm) and a snow throwing wheel with controlled rotational speed (1000-5000 rpm) to gently handle snow. The detection module senses road surface conditions and adjusts operating parameters locally to minimize damage while maintaining snow removal capability.
Solution Approach 2:
The device changes operational parameters such as rotational speeds of working components and advancing speed based on detection module feedback about snow depth, road surface condition, and environmental factors. This dynamic parameter adjustment enables effective snow removal while protecting the road surface from excessive mechanical stress.
3Ease of operation
If automatic moving capability is added to snow removal devices, then labor intensity is reduced, but energy consumption increases
Solution Approach 1:
The device is fully autonomous, with the control module automatically coordinating the moving module and working module based on detection module input. The energy module manages power distribution and monitors battery levels, enabling the device to service itself without human intervention while optimizing energy consumption through intelligent control algorithms.
Solution Approach 2:
The detection module continuously monitors environmental conditions and device status, providing feedback to the control module which adjusts the operation of the moving and working modules in real-time. This feedback mechanism optimizes energy consumption by adapting power usage to actual snow removal needs and environmental conditions.
