Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern building infrastructures face challenges in reducing energy consumption due to the increasing number of electrical loads from both illumination systems and network structures, particularly with the rising number of wireless network access points.
Innovation Solution
A method for controlling wireless network access points in buildings, where they remain activated when connected to a device or when a person is detected by presence detectors, and are deactivated otherwise, linking the illumination system and network structure for targeted energy savings and enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless network access points are continuously activated to ensure network availability, then network accessibility is improved, but energy consumption increases
Solution Approach 1:
The patent applies dynamics by transitioning the access point system from a static continuous operation state to a dynamic state where access points are selectively activated and deactivated based on real-time presence detection. The system dynamically adjusts the operational state of each access point according to whether persons are detected in its coverage area, optimizing the balance between network availability and energy consumption.
Solution Approach 2:
The system implements self-service by enabling access points to automatically activate or deactivate based on presence detection data from the illumination system. The access points monitor their own operational needs through integration with presence detectors, eliminating the need for manual control while optimizing energy usage based on actual network requirements.
2Reliability
If more wireless network access points are installed to improve network coverage, then network accessibility is improved, but the number of electrical loads and energy consumption increase
Solution Approach 1:
The patent applies universality by integrating the network access point function with the illumination system infrastructure. Presence detectors that are already part of the illumination system are repurposed to control access point activation, making the existing system serve multiple functions (lighting control and network management) without adding separate control infrastructure.
Solution Approach 2:
The system implements discarding and recovering by deactivating access points in areas where no persons are detected, effectively removing their energy consumption from the active load. When persons are detected, the access points are recovered (reactivated) to provide necessary network coverage, optimizing the utilization of installed infrastructure.
3Ease of manufacture
If presence detectors from the illumination system are used to control access points, then implementation cost is reduced, but the illumination system and network structure become functionally linked increasing system complexity
Solution Approach 1:
The patent applies merging by combining the control functions of the illumination system and network structure into a unified system. The presence detection capability of the illumination system is merged with the access point control function, creating an integrated system that manages both lighting and network access based on occupancy without requiring separate control mechanisms.

AI summary
A method for controlling at least one wireless network access point in a building may include detecting whether a wireless communication device is connected to at least one wireless network access point and/or whether a person is present using a group of presence detectors. An illumination system may include at least one wireless network point and/or the group of presence detectors. An activated network access point may remain activated when the wireless network access point is connected to a wireless communication device and/or when a person is present. A network access point may be automatically deactivated when the wireless network access point is not connected to a wireless communication device and/or when a person is not present. A deactivated network access point may be automatically reactivated when the wireless network access point is connected to a wireless communication device and/or when a person is present. Combinations thereof are also possible.
