Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sensing devices and complex algorithms are added to improve interaction capability, then the robot's ability to recognize and respond to user emotions and environmental stimuli is improved, but the device complexity increases
Solution Approach 1:
The interaction system is divided into distinct functional modules: audio capturing module, image capturing module, pressure sensing module, odor sensing module, neural network analysis module, and response execution module. Each module handles a specific aspect of interaction, making the complex system manageable and maintainable while achieving comprehensive interaction capabilities
Solution Approach 2:
The robot integrates multiple sensing devices (audio, image, pressure, odor) and output devices (audio output, expression output, movement output) into a single platform that can handle various types of interactions simultaneously. The neural network analysis module processes multiple input types (audio information, image information, sensing data) to generate comprehensive responses, making the system versatile across different interaction scenarios
2Measurement precision
If neural network and deep learning algorithms are used to accurately understand user emotions, then the measurement precision of emotion recognition is improved, but the loss of time for processing increases
Solution Approach 1:
The system performs preliminary processing of input data before neural network analysis. Audio information is captured and preprocessed, image information is captured and preprocessed, and sensing data is collected in advance. This preliminary action prepares the data in an optimized format, reducing the processing time required by the neural network while maintaining high recognition accuracy
Solution Approach 2:
The interaction system operates continuously, with the neural network analysis module constantly processing incoming data streams from multiple sensors. The system maintains continuous monitoring of user emotions and environmental stimuli, eliminating idle processing time and ensuring real-time response capabilities through uninterrupted analysis
