Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional autonomous driving systems using guide rails and conveyer belts are used, then large production lines and mass production processes can be automated, but the system becomes too complex and costly for small work sites and lightweight product transfer
Solution Approach 1:
The patent extracts the essential autonomous driving function from the complex guide rail and conveyer belt system, isolating only the necessary control components (wireless communication module, sensor module, control module) needed for lightweight autonomous movement, thereby reducing system complexity while maintaining automation capability
Solution Approach 2:
The patent employs cost-effective, simple components such as standard wireless communication modules, basic sensors (ultrasonic, infrared, or camera), and conventional microcontrollers instead of expensive industrial-grade guide rail systems, making autonomous driving accessible for small work sites and lightweight applications
2Productivity
If complex autonomous driving infrastructure is installed, then mass production efficiency is improved, but the implementation cost becomes prohibitive for general users and small work sites
Solution Approach 1:
The patent designs a universal autonomous driving control apparatus that can be applied to various moving objects (shopping carts, strollers, lightweight carriers) without requiring site-specific infrastructure installation, thereby reducing implementation costs while maintaining work efficiency across different applications
Solution Approach 2:
The system uses the moving object's own sensors and onboard computer to autonomously navigate and avoid obstacles, eliminating the need for external guide rails or infrastructure, thereby significantly reducing implementation costs for general users
3Speed
If the moving object follows the user closely, then responsiveness to user movement is improved, but the user experiences discomfort and safety concerns
Solution Approach 1:
The patent implements dynamic distance adjustment where the separation distance between the moving object and user is not fixed but adapts based on user preferences, environmental conditions, and safety requirements, allowing the system to maintain optimal responsiveness while preventing user discomfort or safety issues
4Object-affected harmful factors
If the moving object maintains a fixed separation distance from the user, then user comfort is improved, but the system lacks adaptability to different usage scenarios and user preferences
Solution Approach 1:
The patent implements dynamic distance adjustment where the separation distance between the moving object and user is not fixed but adapts based on user preferences, environmental conditions, and safety requirements, allowing the system to maintain optimal responsiveness while preventing user discomfort or safety issues
Solution Approach 2:
The system pre-defines multiple driving modes (follower mode, parallel mode, leader mode) with characteristic distance relationships, allowing users to select appropriate modes before operation based on their specific needs, thereby providing adaptability without requiring complex real-time calculations
