Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Environmental sensors positioned in inaccessible areas often experience connectivity issues with remote monitoring systems, requiring manual intervention to reestablish wireless connections due to changes in network configurations or power sources, which can disrupt data collection and monitoring operations.
Innovation Solution
A wireless environmental sensor device equipped with a processor unit, monitor module, and radio module that automatically toggles to a wireless access point mode to reestablish connectivity and adjusts monitoring parameters based on power source changes, enabling remote configuration adjustments and seamless data offloading without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sensor device operates in client mode connecting to remote access points, then data can be transmitted to remote monitoring systems, but connectivity is lost when network configurations change or access points move
Solution Approach 1:
The radio module dynamically switches between client mode and access point mode based on connectivity conditions. When connected to a remote access point, it operates in client mode for data transmission. When connectivity is lost, it automatically transitions to access point mode to enable local configuration access, making the system adaptable to changing network environments.
Solution Approach 2:
The sensor device autonomously detects connectivity loss and self-corrects by switching to access point mode, enabling a technician to reconnect without manual intervention at the remote sensor location. The device serves itself by maintaining configurability and connectivity resilience independently.
2Reliability
If the sensor device is placed in inaccessible areas for optimal monitoring, then monitoring coverage is improved, but manual intervention becomes difficult when connectivity issues occur
Solution Approach 1:
The device automatically switches to access point mode when connectivity is lost, allowing technicians to reconnect from a distance using their mobile devices. This eliminates the need for physical access to the sensor location, making the system self-sufficient in maintaining operational connectivity.
Solution Approach 2:
The access point mode acts as an intermediary mechanism between the remote sensor and the technician's device. It creates a local wireless network that bridges the gap when the primary remote connection is unavailable, enabling remote reconfiguration without physical presence.
3Use of energy by moving object
If the radio module operates continuously in client mode, then power consumption is reduced, but connectivity cannot be reestablished when network changes occur
Solution Approach 1:
The radio module dynamically adjusts its operational mode based on connectivity status. It operates in low-power client mode when connected to a remote access point, and switches to access point mode only when necessary to restore connectivity, optimizing power consumption while maintaining reliability.
Solution Approach 2:
The system changes the operational parameter of the radio module (client mode vs. access point mode) based on connectivity conditions. This parameter change enables the module to adapt its behavior and power consumption characteristics to the current operational context.

AI summary
A wireless environmental sensor or monitoring device includes a sensor configured to detect an environmental parameter. A radio module is configured to wirelessly communicate data corresponding to the detected environmental parameter to a remote system. The device also includes logic executable by a processor unit to switch the radio module between a wireless access point (AP) operating mode and a wireless client operating mode.
