Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sensor networks face inefficiencies due to continuous power consumption and difficulty in managing data from a growing number of sensors, as they collect information constantly without considering optimal data collection intervals, leading to unnecessary power usage and challenges in data management.
Innovation Solution
A method and apparatus for determining an appropriate sensor data collection cycle based on weightings such as energy savings, data storage space, data processing time, and error probability, which adaptively collects and manages sensor data, optimizing power usage and resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are activated continuously to collect information, then real-time monitoring capability is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic action by determining optimal data collection cycles rather than continuous activation. The system calculates appropriate intervals based on service requirements, sensor characteristics, and weighting factors, activating sensors only at determined cycles to reduce power consumption while maintaining monitoring capability.
Solution Approach 2:
The patent applies dynamics by making the data collection cycle adaptive rather than fixed. The system dynamically determines collection intervals based on service characteristics, sensor profiles, and changing conditions, allowing the monitoring strategy to adjust to different operational requirements.
2Loss of energy
If data collection cycle is increased to save energy, then power consumption is reduced, but data processing time and storage space requirements increase
Solution Approach 1:
The patent applies parameter changes by optimizing the data collection cycle parameter based on multiple weighting factors including energy savings, data storage space, and data processing time. The system adjusts the collection interval parameter dynamically to balance these competing requirements and achieve optimal overall performance.
Solution Approach 2:
The patent implements local quality by determining different data collection cycles for different services and sensors based on their specific characteristics. Each service receives customized collection intervals tailored to its requirements, rather than applying a uniform cycle to all sensors.
3Adaptability or versatility
If more sensors are installed to expand monitoring coverage, then system capability is improved, but data management complexity increases
Solution Approach 1:
The patent applies segmentation by organizing sensors into groups based on service requirements and characteristics. The system manages different sensor populations separately with customized collection cycles, dividing the complex task of managing all sensors into manageable segments based on their functional roles.
Solution Approach 2:
The patent implements universality by creating a unified management framework that handles diverse sensor types and services through a common architecture. The system provides universal services for data collection, management, and processing across different sensor domains while maintaining specialized handling for specific service requirements.
