Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If sequential processing of image and audio information is used, then device complexity is reduced, but real-time responsiveness deteriorates
Solution Approach 1:
The patent divides the processing system into multiple independent cores: one core dedicated to image processing and another core dedicated to audio processing and voice response generation. This segmentation allows parallel execution of image and audio tasks, eliminating the sequential processing bottleneck while maintaining manageable device complexity through modular architecture.
Solution Approach 2:
The patent combines image processing and audio processing into a single integrated guide system that operates simultaneously on multiple cores. By merging these functions into one device with parallel processing capability, the system achieves real-time responsiveness without requiring multiple separate devices, thus balancing performance improvement with device complexity constraints.
2Productivity
If high-performance processing is implemented, then real-time analysis capability is improved, but power consumption increases
Solution Approach 1:
The patent segments the processing workload across multiple specialized cores, allowing each core to handle specific tasks efficiently. The image processing core handles visual analysis while the audio processing core handles voice generation, enabling real-time analysis capability without requiring all processing resources to operate at maximum capacity simultaneously, thus reducing overall power consumption.
Solution Approach 2:
The system employs optimized algorithms and data structures that reduce redundant computations. The image processing module uses efficient object detection algorithms that converge quickly, and the audio module generates voice responses directly from processed data without excessive intermediate processing steps, allowing the system to achieve real-time performance with lower power consumption.
3Adaptability or versatility
If comprehensive guide functions are provided, then usability for visually impaired is improved, but device complexity increases
Solution Approach 1:
The patent designs a guide system that performs multiple functions through a unified architecture: image capture, object detection, image processing, audio processing, and voice response generation all occur within a single integrated device. This multi-functionality provides comprehensive guide capabilities for visually impaired users without requiring multiple separate devices, thus improving usability while controlling device complexity through integration.
Solution Approach 2:
The patent segments comprehensive guide functions into distinct processing modules that operate in parallel: visual sensing module for image capture, image processing module for object detection and analysis, audio processing module for voice synthesis, and output module for audio delivery. This modular segmentation enables comprehensive functionality while maintaining manageable system complexity through clear separation of concerns and independent module optimization.
4Speed
If image processing and voice response are processed sequentially, then device complexity is reduced, but processing speed deteriorates
Solution Approach 1:
The patent segments the processing pipeline into parallel independent streams: image processing operations run on one processor core while audio processing and voice response generation run on another core. This segmentation eliminates the sequential dependency where voice response must wait for image processing to complete, thereby increasing processing speed while maintaining reasonable device complexity through modular parallel architecture.
