Solution Overview
Problem
Current route-guiding systems do not dynamically adjust recommended routes based on a user's real-time physical condition, leading to potential safety issues and inefficiencies, especially in changing environments like intersections.
Innovation Solution
A method and apparatus that obtain and update a user's body information, combine it with geographic data, and dynamically change the recommended route based on user profile and real-time physical condition, using sensors and GPS for route determination and guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional route-guiding systems are used, then route guidance is provided based on static geographic information, but the system cannot adapt to real-time changes in user physical condition
Solution Approach 1:
The patent implements dynamic route recommendation by continuously monitoring user body information (heart rate, temperature, etc.) and adjusting the recommended route in real-time based on changes in physical condition. The route determination unit dynamically recalculates optimal routes when body information changes exceed predetermined thresholds, transforming the static route guidance system into an adaptive, dynamic system that responds to user physiological states.
Solution Approach 2:
The system incorporates feedback mechanisms by measuring user body information through sensors, comparing current measurements with reference values, and using this feedback to adjust route recommendations. When body information changes indicate fatigue or stress, the system receives feedback and modifies the route accordingly, creating a closed-loop control system that continuously optimizes based on user response.
2Reliability
If route guidance is provided without considering user physical condition, then the system is simple to operate, but safety issues may arise due to inability to detect user fatigue or stress
Solution Approach 1:
The system performs preliminary actions by establishing reference body information values before route traversal begins and setting predetermined thresholds for body information changes. This preparatory setup enables the system to quickly detect when user physical condition deteriorates to dangerous levels, allowing proactive safety interventions before fatigue or stress becomes critical.
Solution Approach 2:
The patent introduces body information as an intermediary parameter that mediates between the user's physical state and the route guidance system. Sensors measure body information (heart rate, temperature, etc.), which serves as an intermediate indicator of user condition, and this intermediary data drives the route determination logic, enabling indirect monitoring of user safety through physiological parameters.
3Productivity
If the system continuously monitors and updates body information, then route recommendations adapt to real-time conditions, but energy consumption increases
Solution Approach 1:
The system implements periodic monitoring of body information at predetermined time intervals during route traversal rather than continuous monitoring. The route determination unit recalculates optimal routes at regular intervals or when triggered by significant changes, balancing the need for accurate, adaptive recommendations with energy conservation by avoiding constant sensor operation and processing.
Solution Approach 2:
The patent changes the monitoring parameter from continuous to threshold-based detection. Instead of continuously processing all body information data, the system monitors for changes exceeding predetermined thresholds and only triggers route recalculation when significant changes occur. This parameter change approach reduces processing load and energy consumption while maintaining route recommendation accuracy when it matters most.

AI summary
A method and apparatus for recommending a route. The route recommending method includes obtaining user's current body information; obtaining geographic information from a current position to a destination; and determining a recommended route to the destination on the basis of the body information and the geographic information.
