Occupancy Sensor Wireless Transceiver Light Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current occupancy sensors require physical access for reactivating their wireless transceivers, posing safety hazards and being labor-intensive, especially when installed in elevated locations, as remote reactivation is not feasible.
Innovation Solution
Incorporating a light sensing element and processors in the occupancy sensor that allow activation and deactivation of the wireless transceiver using predetermined light signals, enabling remote reactivation without physical access, such as through flashing light pulses, to facilitate efficient configuration and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless transceiver is deactivated after configuration to prevent tampering and reduce screen clutter, then security is improved and device visibility is reduced, but the ability to reactivate remotely is lost
Solution Approach 1:
A light sensing element is introduced as an intermediary mechanism to enable remote activation of the wireless transceiver. The light sensor detects specific light patterns (such as flashlight illumination) and triggers the transceiver to become active, allowing remote operation without requiring physical access to the device or maintaining continuous wireless connectivity.
2Object-affected harmful factors
If physical access is required to reactivate the wireless transceiver, then remote tampering is prevented, but labor intensity and safety risks increase
Solution Approach 1:
The mechanical/physical access requirement for reactivation is replaced with an optical system. Instead of requiring a user to physically press buttons or access device controls, a light sensing element detects light patterns (such as from a flashlight) and triggers the transceiver activation, substituting mechanical interaction with optical detection.
3Adaptability or versatility
If the transceiver remains active to allow remote reactivation, then operational flexibility is improved, but vulnerability to tampering and screen clutter increases
Solution Approach 1:
The transceiver operates in periodic cycles rather than remaining continuously active. It activates temporarily in response to detected light patterns, allows for configuration or reactivation, and then deactivates after a predetermined period. This periodic operation provides operational flexibility while limiting the window of vulnerability to tampering and reducing screen clutter on remote devices.

AI summary
An occupancy sensor preferably includes an occupancy sensing element configured to detect moving objects within an area of coverage, and a wireless transceiver configured to facilitate wireless coupling of the occupancy sensor to a remote device to facilitate remote wireless configuration and/or commissioning of the occupancy sensor. The wireless transceiver can be configured to be activated in response to a light sensing element of the occupancy sensor being exposed to one or more flashes of light. The wireless transceiver can be de-activated after configuration.
