Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle navigation systems fail to automatically determine and provide effective alternate routes when a vehicle slows or stops due to traffic or road conditions, leading to inefficiencies in reaching a destination.
Innovation Solution
A navigation system that includes a motion sensor to detect vehicle velocity and a controller that generates alternate routes if the vehicle's motion falls below a predetermined threshold, allowing for automatic or user-initiated route replanning to avoid congested areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the navigation system continues along the primary route without monitoring vehicle motion, then the route guidance remains simple and unchanged, but the system fails to adapt to traffic conditions and cannot provide effective alternate routes
Solution Approach 1:
The system performs preliminary monitoring of vehicle motion parameters (velocity, acceleration) continuously along the primary route before any detour is needed. This advance detection allows the system to prepare alternate routes in advance and switch seamlessly when motion thresholds are violated, improving adaptability without adding complex real-time decision architecture.
Solution Approach 2:
The navigation system incorporates feedback from motion sensors that continuously monitor vehicle velocity and acceleration. When the vehicle's motion falls below predetermined thresholds (indicating traffic congestion or stopped conditions), the system receives feedback and automatically generates alternate routes. This closed-loop feedback mechanism enables adaptive route planning while maintaining relatively simple system architecture through threshold-based triggering.
2Productivity
If the system generates alternate routes automatically based on motion thresholds, then the system responds effectively to traffic conditions, but the system complexity increases due to additional sensors and control logic
Solution Approach 1:
The navigation system performs self-service route replanning by automatically monitoring its own vehicle motion parameters and triggering alternate route generation when thresholds are violated. The system serves itself by using onboard motion sensors to detect congestion conditions and autonomously determining when route changes are necessary, eliminating the need for external intervention or complex centralized control while improving routing efficiency.
Solution Approach 2:
The system uses parameter changes in motion thresholds (velocity, acceleration) as triggering conditions for route replanning. By monitoring changes in these physical parameters and comparing them against predetermined values, the system achieves efficient automatic route selection without requiring complex decision-making algorithms or additional computational overhead, thus improving productivity with minimal complexity increase.
3Reliability
If the navigation system monitors vehicle motion continuously, then the system can detect stopped or slowed conditions and provide timely alternate routes, but the energy consumption and computational load increase
Solution Approach 1:
The system implements periodic monitoring of vehicle motion parameters at predetermined intervals rather than continuous high-frequency analysis. This periodic action maintains reliable detection of stopped or slowed conditions while significantly reducing computational load and energy consumption compared to continuous monitoring, achieving a balance between reliability and energy efficiency.
Solution Approach 2:
The system uses feedback from motion sensors that trigger route replanning only when predetermined motion thresholds are violated. This threshold-based feedback mechanism ensures reliable detection of problematic conditions while minimizing unnecessary computational processing and energy consumption during normal driving conditions, thereby maintaining reliability without excessive energy expenditure.

AI summary
A method of and apparatus for generating an alternate route for a system to travel to a predetermined destination are described. The method comprises determining a velocity of a system traveling along a primary route; and generating an alternate route to the primary route if the system velocity is below a predetermined motion threshold. A navigation system for generating an alternate route to a destination includes a motion sensor for detecting the navigation system velocity along a primary route and a controller coupled with the motion sensor. The controller receives a motion signal indicating navigation system motion and generates an alternate route to the primary route responsive to the motion signal indicating navigation system motion different from a predetermined motion threshold value.
