Innovation Solution
A walking cane device with an adjustable elongated shaft, a computer module, a receiver and transmitter system, and a wireless earpiece that provides pre-programmed navigation data and real-time information through a speaker, utilizing a remote global positioning satellite system for enhanced navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional white cane is used for navigation, then it provides basic ground contact feedback, but it lacks real-time audio feedback and advanced navigation capabilities
Solution Approach 1:
The patent combines multiple functions into a single walking cane device: GPS receiver for location tracking, computer module for processing navigation data, speaker member for audio feedback, and receiver member for ground surface detection. This integration allows the device to provide comprehensive real-time information about terrain features and hazards while maintaining a unified portable form factor.
Solution Approach 2:
The walking cane serves multiple functions simultaneously: it acts as a traditional walking aid for ground contact, a GPS navigation device for location tracking, an audio feedback system for real-time information delivery, and a ground surface detector for hazard identification. This multi-functionality addresses the information loss problem by providing diverse navigation capabilities in one device.
2Ease of operation
If audio feedback system is added to provide real-time terrain information, then navigation capability is improved, but device weight and complexity increase
Solution Approach 1:
The patent replaces mechanical ground contact feedback with electronic and acoustic systems. The receiver member detects ground surface characteristics electronically, the computer module processes this data, and the speaker member converts it to audible feedback. This substitution provides richer information delivery without requiring heavy mechanical components, improving navigation ease while managing weight.
3Measurement precision
If GPS and computer module are integrated into the cane, then navigation precision is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The computer module is pre-programmed with mapping data, hazard information, and navigation algorithms before use. The device receives GPS signals and automatically processes location data against pre-stored maps to provide real-time navigation guidance. This preliminary preparation enables precise location tracking and route guidance without requiring complex real-time computation during operation, managing system complexity while maintaining high measurement precision.
