Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing automatic steering systems are used, then steering accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The steering system is divided into separate functional modules: a portable control unit with motor and drive assembly, and a separate guidance system. The control unit can be detached and transferred between vehicles, eliminating the need for permanent installation infrastructure.
Solution Approach 2:
The motor and drive assembly are extracted from the vehicle's fixed steering system and placed in a portable handheld unit. This extraction allows the steering function to be separated from the vehicle's electrical and mechanical infrastructure.
2Measurement precision
If existing automatic steering systems are used, then steering accuracy is improved, but installation complexity increases
Solution Approach 1:
The system is segmented into a portable control unit that requires no permanent installation. The unit attaches to the steering wheel through a simple mechanical interface, eliminating complex wiring and mounting procedures.
Solution Approach 2:
By extracting the motor and control functions from the vehicle's fixed infrastructure and placing them in a portable unit, the installation process is simplified to mere attachment rather than permanent integration.
3Extent of automation
If existing automatic steering systems are used, then steering automation is improved, but adaptability between vehicles decreases
Solution Approach 1:
The control unit is designed as a dynamic, movable system that can be attached to and removed from different steering wheels. The mechanical interface adapts to different steering wheel sizes and configurations, enabling use across multiple vehicle types.
Solution Approach 2:
The portable control unit is designed with universal compatibility to work with various vehicle models. The same unit can be transferred between different vehicles without modification, providing multi-functionality across the fleet.
