Device Management Mediator for Sensor Network Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In sensor networks and device networks, it is inefficient for users to find and utilize devices that meet their specific needs due to a large number of available options, and existing systems lack convenient methods for device control and function extension.
Innovation Solution
A device management apparatus that mediates between device owners and users, allowing users to select devices based on desired conditions and granting control rights, while also enabling the addition of software modules to extend device functions, thereby simplifying device usage and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of registered sensors in the sensor network increases, then the variety of sensor choices increases, but it becomes difficult for users to find the optimal sensor and convenience is reduced
Solution Approach 1:
The patent introduces a sensor management apparatus as an intermediary between sensor owners and users. This mediator stores sensor information, receives use requests from users, performs matching between user requirements and sensor characteristics, and grants control rights. This resolves the contradiction by automating the search process through the mediator, maintaining ease of operation while supporting a large variety of sensors.
2Reliability
If sensors are installed at various places for data collection, then the coverage and data availability improve, but the sensors remain unused during idle time causing resource waste
Solution Approach 1:
The patent implements dynamic sensor allocation where sensors transition between idle and active states based on real-time user requests. The sensor management apparatus receives use requests, matches them with available sensors, and dynamically grants control rights for specific time periods. This ensures sensors are reliably available when needed while minimizing energy waste during idle periods through on-demand activation.
3Measurement precision
If users need to change sensor settings from default to obtain desired data, then the data accuracy improves, but the complexity of device control increases
Solution Approach 1:
The patent extracts the complex task of sensor configuration from the user and transfers it to the sensor management apparatus. When a user submits a use request with desired conditions, the management apparatus automatically matches these conditions with sensor settings, performs necessary configuration changes, and grants control rights. This extraction maintains measurement precision by ensuring proper configuration while eliminating the complexity burden from users.

AI summary
A device management apparatus that mediates between an owner of a device and a user who is not the owner of the device in order to permit the user to use the device, includes a device information storage section in which information on each of a plurality of devices is registered, an acquisition section which acquires a desired condition from a user, and a matching process section which performs matching between the desired condition acquired from the user and the information on each device registered in the device information storage section thereby selecting a device satisfying the desired condition as a target device, generating contract information related to the use of the target device between an owner of the target device and the user, and granting a control right of the target device to the user.
