Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Identifying defective IoT devices before or during deployment in a large network is difficult, leading to potential costly failures in IoT systems, especially in asset tracking applications.
Innovation Solution
A method and system for auditing IoT devices, including adhesive tape platforms, to determine functionality and capability before or during deployment, with remote initiation and tracking of audit results, allowing for replacement of defective devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a large network of wireless IoT devices is deployed without pre-deployment auditing, then deployment speed and scale are improved, but system reliability and task success rate deteriorate due to defective devices
Solution Approach 1:
The patent implements pre-deployment auditing that performs diagnostic tests, functional checks, and capability verification on IoT devices before they are deployed to tasks. This preliminary action identifies defective devices early, preventing them from being deployed and thus maintaining system reliability while enabling rapid deployment of verified functional devices.
2Reliability
If pre-deployment auditing is performed on all IoT devices, then device functionality and system reliability are improved, but audit time and deployment complexity increase
Solution Approach 1:
The patent implements risk-based auditing that performs comprehensive audits on high-criticality devices while using simplified audit protocols for low-criticality devices. This partial action approach focuses auditing resources on devices where defects would cause the most harm, reducing overall audit time while maintaining reliability for critical functions.
Solution Approach 2:
The patent dynamically adjusts audit parameters such as test depth, duration, and complexity based on device criticality, task requirements, and historical performance data. This allows the auditing system to optimize the balance between thoroughness and time consumption by changing audit parameters rather than using a fixed protocol for all devices.
3Measurement precision
If comprehensive diagnostic tests are performed on IoT devices, then measurement precision of device functionality is improved, but device complexity and test resource requirements increase
Solution Approach 1:
The patent segments the comprehensive diagnostic test into multiple independent test modules that can be executed selectively based on device type, criticality, and task requirements. Each module tests specific functionalities independently, allowing the system to achieve high measurement precision for relevant functions while avoiding unnecessary tests that would increase complexity.
Data Source
AI summary
Disclosed herein is a method and system for performing audits of one or more IOT devices in an IOT system, prior to deployment of the IOT device or during deployment in the field. The audits are used to determine if an IOT device is functional and capable of performing a task assigned to the IOT device. If an audit is failed, the IOT system may determine that the IOT device is defective and needs to be replaced for the respective task. The IOT system remotely initiates the audits, and tracks the status and results of the audits of the IOT devices.
