Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple assistance modes are provided with different drive parameters, then the versatility and adaptability of the electric bicycle is improved, but the device complexity increases due to the need to manage and store multiple sets of drive parameters
Solution Approach 1:
The patent segments the assistance modes into distinct categories (e.g., eco mode, tour mode, sport mode, turbo mode) with separate drive parameter sets stored in memory. Each mode is independently manageable and can be selected by the user, allowing the system to handle multiple configurations without overwhelming complexity.
Solution Approach 2:
The system dynamically switches between different drive parameter sets based on the selected assistance mode. The ride controller adapts its behavior in real-time by loading the appropriate parameter set from memory, enabling flexible adaptation to different riding conditions without requiring permanent complex hardware modifications.
2Adaptability or versatility
If the system stores multiple sets of drive parameters for different assistance modes, then the adaptability is improved, but the memory requirements and data management complexity increase
Solution Approach 1:
The drive parameters are segmented into distinct sets, with each assistance mode having its own dedicated parameter set stored in memory. This organization allows efficient storage and retrieval of parameters without requiring a monolithic data structure, reducing overall data management complexity.
Solution Approach 2:
The system pre-stores multiple sets of drive parameters in memory before operation. This preliminary action allows the ride controller to quickly switch between different parameter sets based on user selection without requiring real-time calculations or complex data processing during actual riding.
3Adaptability or versatility
If the operating interface provides detailed configuration options for drive parameters, then the ease of customization is improved, but the ease of operation decreases due to the complexity of the interface
Solution Approach 1:
The configuration interface is segmented into mode-specific sections, with each assistance mode presenting its own simplified configuration options. This allows users to customize parameters relevant to their specific mode without being overwhelmed by all available parameters across all modes simultaneously.
Solution Approach 2:
The interface provides detailed configuration options only when needed, such as when a user selects a specific assistance mode or enters configuration mode. The default operation remains simple with pre-configured modes, while detailed customization is available on demand without adding permanent complexity to the basic operation.
