Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation devices and compliance evaluation systems are inadequate in emergency situations, as they fail to provide precise location-specific guidance and often rely on incomplete or ambiguous rules, leading to uncertainty and inconvenience.
Innovation Solution
A portable device using machine learning to construct a venue model based on pre-entry information, which is trained further upon entry, generates an escape plan when a threat is detected, and determines compliance with rules using sensors and server data, providing clear guidance for safe egress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a machine learning model is trained on general data and then fine-tuned with specific case data, then the measurement precision and compliance determination accuracy are improved, but the loss of time for model preparation and processing is increased
Solution Approach 1:
The system performs preliminary training on general compliance data before the specific case occurs, building a base model that can be quickly fine-tuned. This preliminary preparation reduces the time needed during actual compliance determination while maintaining high accuracy through subsequent fine-tuning with case-specific data.
Solution Approach 2:
The system extracts and separates the model training process into distinct phases: general compliance pattern learning and case-specific fine-tuning. This extraction allows the system to pre-load general knowledge while minimizing real-time processing requirements for specific cases.
2Reliability
If detailed rules are established to cover all compliance scenarios, then the reliability of compliance determination is improved, but the device complexity and difficulty of rule compilation increase
Solution Approach 1:
The system replaces manual rule compilation and mechanical judgment processes with a machine learning model that automatically learns compliance patterns from data. This substitution eliminates the need for complex hand-crafted rules while improving reliability through consistent, data-driven decision-making.
Solution Approach 2:
The machine learning model performs self-training and self-adjustment based on input data, automatically adapting to compliance requirements without requiring manual rule updates. This self-service capability reduces the complexity of rule compilation while maintaining high reliability through continuous learning.
3Ease of operation
If explicit rules are communicated to parties for compliance, then the ease of operation is improved, but the loss of information occurs due to ambiguous rule interpretation
Solution Approach 1:
The system provides feedback to parties about their compliance status based on machine learning analysis, replacing ambiguous rule interpretation with objective, data-driven assessments. This feedback mechanism maintains ease of operation while eliminating information loss due to subjective rule interpretation.
4Measurement precision
If comprehensive sensor data is collected for compliance determination, then the measurement precision is improved, but the use of energy and device complexity increase
Solution Approach 1:
The system collects comprehensive sensor data but processes only the most relevant features for compliance determination using the machine learning model. This partial processing approach maintains high measurement precision while reducing energy consumption compared to analyzing all sensor data in detail.
Data Source
AI summary
A system and method of navigating in areas. A machine learning model is trained in multiple levels with data concerning basic interpretation of sensors and with analysis of the layout of areas. The model is downloaded to a second processor which may further train the model with sensor data gathered after the download. Additional sensor data along with data from a server or other sources may be used as an input to the model and the second or another processor evaluates the model with the inputs to create outputs which determine the state of compliance. Specific applications include movement around in areas of interest. A vehicle which is controlled by a driver or by data from the machine loading model and it's analysis may be included. The model is used to calculate a path which may be displayed in visual, auditory or tactile modes.
