Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional public transportation information systems are used, then general information is provided, but visually and hearing-impaired persons cannot obtain sufficient tactile paving and voice guidance information
Solution Approach 1:
The system segments information provision by creating separate acquisition units for different types of information (operation status acquisition unit, tactile paving information acquisition unit). This segmentation allows targeted collection and processing of specific information types needed by visually and hearing-impaired persons, ensuring comprehensive coverage without mixing information categories.
Solution Approach 2:
The system introduces a map generation unit as an intermediary that integrates operation status information and tactile paving information to create comprehensive guidance maps. This intermediary process transforms raw data from multiple sources into synthesized, accessible visual and audio guidance that bridges the information gap for visually and hearing-impaired persons.
2Measurement precision
If detailed real-time information is provided to visually and hearing-impaired persons, then navigation accuracy improves, but system complexity increases
Solution Approach 1:
The system achieves multi-functionality by having the map generation unit process multiple types of information (operation status, tactile paving data) through a single integrated process. The voice guidance unit then delivers synthesized guidance that serves both general navigation needs and specific accessibility requirements, reducing overall system complexity while maintaining high navigation accuracy.
Solution Approach 2:
The system performs preliminary information gathering by acquiring operation status and tactile paving information in advance through dedicated acquisition units. This preliminary action allows the map generation unit to pre-process and integrate data before actual navigation occurs, reducing real-time processing complexity while ensuring accurate, up-to-date guidance information is available.
3Reliability
If comprehensive guidance information is provided, then user safety and efficiency improve, but information processing time increases
Solution Approach 1:
The system maintains continuous information flow by operating multiple acquisition units simultaneously (operation status acquisition, tactile paving information acquisition). This continuous parallel data collection ensures comprehensive guidance information is generated without interruption, maintaining user safety while optimizing processing time through concurrent operations rather than sequential processing.
Data Source
AI summary
The system according to the embodiment includes an operation status acquisition unit, a tactile paving information acquisition unit, a map generation unit, and a voice guidance unit. The operation status acquisition unit acquires the operation status of each public transportation facility. The tactile paving information acquisition unit acquires tactile paving information from each local government. The map generation unit generates a map based on the information acquired by the operation status acquisition unit and the tactile paving information acquisition unit. The voice guidance unit provides voice guidance based on the map generated by the map generation unit.
