Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If specialized parameter setting methods are used to provide appropriate assist force, then the assist effectiveness is improved, but the ease of operation deteriorates due to requiring specialized knowledge
Solution Approach 1:
The patent introduces an intermediary interface between the user and the complex parameter settings. This interface translates simple user inputs (such as desired assist level selections) into optimized parameter configurations automatically, eliminating the need for users to have specialized knowledge while maintaining assist effectiveness.
Solution Approach 2:
The system performs self-configuration by automatically adjusting parameters based on detected user characteristics and task requirements. The device monitors user physiology and action patterns, then autonomously optimizes control parameters without requiring manual intervention or specialized knowledge from the user.
2Adaptability or versatility
If multiple parameters are adjusted to optimize assist force, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent segments the parameter adjustment process into distinct functional modules: detection module for gathering user data, processing module for analyzing patterns, and control module for adjusting parameters. This segmentation allows the system to handle multiple parameters systematically without overwhelming complexity.
Solution Approach 2:
The system dynamically adjusts parameters in real-time based on changing user needs and conditions. Rather than requiring manual configuration of multiple static parameters, the system continuously monitors user state and automatically adapts parameters, reducing the perceived complexity while maintaining high adaptability.
