Wireless Sensor Tag Detection and Data Collection via Intermediary Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conventional sensor applications, sensors often lack connectivity, leading to time-intensive manual data collection, especially when they do not include long or medium range connectivity capabilities.
Innovation Solution
Associating sensors with tags that use short range wireless protocols for data transmission, allowing electronic devices to detect and collect sensor information, which is then communicated to an application server through a network of tag reader/detector devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If sensors are equipped with long-range connectivity capabilities, then data transmission distance is improved, but device complexity and cost increase
Solution Approach 1:
The patent introduces an intermediary device (electronic device with tag reader) that collects sensor data via short-range wireless communication and transmits it to remote servers. This mediator handles the long-range communication burden, allowing sensors to remain simple while achieving remote data access.
2Length of stationary object
If sensors include long-range connectivity, then communication range is improved, but power consumption increases
Solution Approach 1:
The system segments the communication function into two parts: sensors use low-power short-range wireless for data transmission to nearby electronic devices, while the electronic devices handle long-range network communication. This segmentation allows sensors to maintain low power consumption while still achieving remote data access.
3Device complexity
If manual data collection is used for sensors without connectivity, then device complexity is reduced, but productivity decreases
Solution Approach 1:
The system enables self-service data collection where electronic devices automatically detect tags, establish communication links, and collect sensor data without manual intervention. This automated approach maintains simple sensor design while dramatically improving data collection productivity through wireless communication.

AI summary
An electronic device is operated by detecting a tag having a sensor associated therewith and being configured to transmit information over a defined distance using a short range wireless protocol, and receiving sensor information transmitted by the tag over the communication link.
