Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a wristband is used to collect surface electromyogram signals for gesture recognition, then the device structure is simple, but the gesture recognition accuracy is insufficient
Solution Approach 1:
The device is segmented into multiple functional components: detecting electrodes for EMG signal acquisition, sensors for three-dimensional motion data collection, and an elastic member forming a glove structure. This segmentation allows each component to specialize in specific detection tasks, improving overall measurement precision while distributing system complexity across modular elements.
Solution Approach 2:
The patent merges multiple detection functions into a single integrated glove device. The detecting electrode and sensor are combined within the same elastic member structure, enabling simultaneous acquisition of both surface electromyogram signals and three-dimensional motion data. This combination allows the system to overcome the limitations of single-modality detection and achieve more accurate gesture recognition.
2Measurement precision
If multiple sensors and detecting electrodes are integrated into the elastic member, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The elastic member serves multiple functions simultaneously: it acts as the structural base for mounting detecting electrodes, provides the mounting structure for sensors, and functions as the interface with the user's body. This multi-functionality reduces the need for separate structural components, thereby improving detection capabilities without proportionally increasing device complexity.
Solution Approach 2:
The patent employs an elastic member in the form of a flexible glove structure that conforms to the user's hand. This flexible shell approach allows detecting electrodes and sensors to be integrated into a thin, adaptable form factor that maintains close contact with the body for accurate signal acquisition, while the flexibility itself simplifies the overall structure compared to rigid mounting systems.
