Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a blind cane is used for navigation, then the device is simple and low cost, but the detection range is limited and cannot detect obstacles above chest level
Solution Approach 1:
The patent combines multiple detection technologies (ultrasonic, infrared, laser) into a single blind guiding system, merging the functions of obstacle detection, positioning, and navigation into one integrated device that overcomes the limitations of simple blind canes
Solution Approach 2:
The blind guiding device is designed with multi-functional capabilities including obstacle detection, precise positioning, route planning, and public transportation guidance, making it a universal solution for various navigation scenarios rather than a single-purpose tool
2Reliability
If a seeing-eye dog is used for assistance, then the detection capability is good, but the training time is long and maintenance cost is high
Solution Approach 1:
The patent replaces the biological seeing-eye dog system with an electronic and acoustic-based blind guiding device that uses ultrasonic and infrared sensors for obstacle detection, eliminating the need for animal training while maintaining detection capabilities
Solution Approach 2:
The device performs self-detection and self-navigation functions through integrated sensors and processing units,无需 external training or human intervention beyond initial setup, making it independently operational
3Productivity
If ultrasonic positioning is used, then the device can measure distance to obstacles, but the positioning precision is insufficient and cannot provide precise location information
Solution Approach 1:
The patent merges satellite positioning technology with ultrasonic positioning to create a hybrid positioning system that combines the broad coverage and speed of satellite-based location with the precision of ultrasonic distance measurement for accurate obstacle localization
Solution Approach 2:
The positioning system uses a composite approach combining multiple positioning methodologies (satellite, ultrasonic, infrared) to achieve both speed and precision that individual methods cannot provide alone
4Ease of operation
If simple obstacle avoidance function is provided, then the device is easy to operate, but the practicability is limited and cannot support complex travel scenarios
Solution Approach 1:
The blind guiding device is designed with universal applicability for various travel scenarios including pedestrian navigation, public transportation guidance, and obstacle avoidance, making it adaptable to complex real-world conditions while maintaining ease of use through automated route planning
Solution Approach 2:
The device dynamically adjusts its guidance strategies based on real-time environmental data, obstacle positions, and selected transportation modes, providing adaptive navigation that responds to changing conditions while keeping the user interface simple
