Smart Meeting Room Automation via Sensor-Based Occupancy Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large corporations, employees face difficulties in finding available meeting rooms on an ad-hoc basis due to block booking and inefficient room utilization, leading to wasted resources and inconvenience.
Innovation Solution
A computing device system that uses sensors to determine the occupancy status of meeting rooms, displays this status via indicators, and automates the reservation process, including preparing meeting-related devices and sending reminders, to optimize room usage and reduce energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If employees book meeting rooms in advance to ensure availability, then meeting room availability is improved, but resource utilization deteriorates due to block booking and wasted time slots
Solution Approach 1:
The system dynamically adjusts meeting room availability based on real-time sensor data and actual usage patterns. Rooms transition between reserved and available states based on detected occupancy, allowing flexible re-allocation of resources that were originally booked but not utilized, thereby improving both reliability and productivity
Solution Approach 2:
The system implements feedback loops where sensor data about actual room usage is continuously monitored and fed back to the reservation system. This feedback mechanism allows the system to learn from actual usage patterns and adjust future availability decisions, resolving the contradiction between guaranteed availability and efficient resource utilization
2Loss of information
If employees wander hallways to find available meeting rooms, then real-time availability information is obtained, but time is lost and convenience deteriorates
Solution Approach 1:
The system introduces an intermediary digital interface (mobile application or web portal) that mediates between the employee and physical meeting rooms. This intermediary provides real-time availability information without requiring employees to physically search hallways, thus eliminating time loss while maintaining accurate information delivery
Solution Approach 2:
The system replaces the mechanical approach of physically wandering hallways with an automated electronic information delivery system. Sensors and communication networks substitute for human physical search, providing real-time availability data instantly to employees wherever they are in the building
3Reliability
If meeting rooms are prepared manually before meetings, then device readiness is ensured, but energy consumption increases and productivity decreases
Solution Approach 1:
The system performs preliminary actions selectively based on predicted meeting requirements and actual attendance. Instead of preparing all devices in all booked rooms in advance, the system pre-configures only the necessary devices in rooms where meetings are actually detected to be occurring, reducing energy consumption while maintaining device readiness when needed
Solution Approach 2:
The system dynamically changes operational parameters of meeting room devices based on real-time conditions. Devices transition between powered-on and powered-off states based on detected occupancy and meeting schedules, optimizing the balance between reliability of device availability and energy consumption by adjusting power states according to actual needs

AI summary
In some examples, a computing device may receive sensor data from sensors in a meeting room, determine that the meeting room is unoccupied, and indicate that the meeting room is unoccupied. The computing device may receive a request to reserve a current time slot of the meeting room and indicate that the meeting room is occupied. The computing device may determine that a meeting is scheduled to begin in the meeting room and place meeting-related devices, such as conferencing devices, in an operational state. The computing device may instruct a conferencing device in the meeting room to access a conference bridge. The computing device may determine a presence of individual meeting invitees in the meeting and display attendance data indicating invitees that are present and invitees that are absent from the meeting. The computing device may automatically send a reminder message to those that are absent.
