Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In crowded asset environments, such as refrigerated trucks shipping perishable goods, multiple wireless sensors face range issues that hinder the precise identification of malfunctioning sensors, leading to increased system cost and complexity when using multiple radio transmitter/receivers.
Innovation Solution
Implementing a system with wireless transceivers that can adjust transmission power between high output for long-range communication and low output for localization, allowing sensors to switch from a Bluetooth Low Energy mode to a Bluetooth Beacon mode for precise localization of malfunctioning sensors without the need for additional radio types.

Engineering Contradiction Analysis
1Length of stationary object
If long range transmission power is used, then communication range is improved, but localization precision deteriorates
Solution Approach 1:
The transceiver dynamically switches between two transmission power modes: high power for long-range monitoring and low power for localization. This dynamic adjustment allows the system to optimize between communication range and localization precision based on the operational phase, resolving the contradiction between these two requirements.
2Measurement precision
If multiple radio transmitter/receivers are used, then localization capability is improved, but system complexity increases
Solution Approach 1:
A single transceiver performs multiple functions by switching between high power mode for monitoring and low power mode for localization. This multi-functionality eliminates the need for separate radio devices, reducing system complexity while maintaining both long-range communication and precise localization capabilities.
Solution Approach 2:
The patent combines the monitoring and localization functions into a single transceiver system rather than using separate devices. By merging these functions and using dynamic power adjustment, the system achieves the localization capability of multiple devices without the associated complexity.
3Measurement precision
If multiple radio transmitter/receivers are used, then localization capability is improved, but system cost increases
Solution Approach 1:
The transceiver is designed to perform both monitoring and localization functions through dynamic power switching, eliminating the need to manufacture and deploy multiple separate radio devices. This reduces overall system cost while maintaining full localization capability.
