Conference System Wake-Up Interface for Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conference systems often find themselves powered down when participants enter the meeting area, as the control device for providing power is typically located in a separate, inaccessible room, leading to inefficiencies and the need for constant power during office hours to ensure readiness.
Innovation Solution
Incorporating a wake-up interface in one of the delegate units, such as a button or switch, allows participants to activate the system from within the meeting area, enabling communication with the control device to power up the system efficiently, with a power-safe mode reducing consumption by up to 95% when not in use, and utilizing an activity detection module to automatically power down during inactivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the control device is located in a separate, inaccessible room, then the system can be secured and centralized, but the system cannot be activated when participants enter the meeting area
Solution Approach 1:
The system is divided into two functional parts: a control device in a secure location and a wake-up interface in the meeting area. This segmentation allows the control device to remain secure and centralized while the wake-up interface provides local activation capability to participants.
Solution Approach 2:
The wake-up interface acts as an intermediary between participants and the control device. It receives activation requests from participants and transmits them to the control device over the network, enabling indirect control without requiring physical access to the control device location.
2Reliability
If the system remains powered on during office hours, then the system is ready for meetings, but power consumption increases
Solution Approach 1:
The system transitions between powered-off and powered-on states based on periodic needs. The wake-up interface enables on-demand activation, allowing the system to be powered off during periods of no use and activated only when meetings are scheduled or participants arrive.
Solution Approach 2:
The system provides self-service activation through the wake-up interface. When participants enter the meeting area, they can autonomously activate the system without requiring manual intervention from system administrators or security personnel.
3Use of energy by moving object
If the system is activated on demand, then power consumption is reduced, but the system may not be ready when participants arrive
Solution Approach 1:
The system performs preliminary activation when meetings are scheduled in advance. The scheduled meeting information triggers early system activation, ensuring the system is fully ready before participants arrive, eliminating startup delays during actual meetings.

AI summary
Conference systems are often installed in plenary halls or meeting rooms, whereby such conference systems typically consist of a central equipment and equipment for the participants of the discussion. The central equipment is usually used to control the conference system and supply power to the participant equipment. A conference system 1 comprising a plurality of delegate units 2,10, whereby the delegate units 2, 10 comprise a microphone 22 for receiving a speech signal from a speaker, a control device 4 for providing the delegate units 2,10 with power, a network connection 6 for connecting the plurality of delegate units 2,10 with the control device 4, whereby the network connection 6 is operable to transmit the power from the control device 4 to the delegate units 2,10, whereby at least one of the delegate units 2,10 is a control delegate unit 10, whereby the control delegate unit 10 comprises a wake-up interface 11, whereby the conference system 1 is operable to activate the control device 4 and/or the other delegate units 2 from an un-activated state into an activated state as a reaction to the use of the wake-up interface 11.
