Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless power is transmitted to multiple building devices simultaneously, then power distribution flexibility is improved, but power management complexity increases
Solution Approach 1:
The system dynamically switches power transmission targets based on zone power modes. The building management system can adaptively change which devices receive power depending on operational requirements, environmental conditions, and device priorities, transforming a static power distribution system into a dynamic one that resolves the complexity of managing multiple simultaneous connections.
Solution Approach 2:
The building is divided into zones with different power modes, and power transmission is segmented to specific devices within those zones. This segmentation approach allows the system to manage complexity by breaking down the overall power distribution task into smaller, zone-specific segments rather than managing all devices globally at once.
2Ease of manufacture
If wireless power transmission is used to eliminate wired connections, then installation ease is improved, but power allocation control becomes more difficult
Solution Approach 1:
The system incorporates feedback mechanisms where the building management system receives information about device status, environmental conditions, and power consumption. Based on this feedback, the system automatically adjusts power allocation to appropriate devices, maintaining ease of control despite the wireless transmission medium that eliminates physical connection management.
3Reliability
If power is continuously transmitted to all devices, then device reliability is improved, but energy efficiency deteriorates
Solution Approach 1:
Instead of continuous power transmission to all devices, the system implements periodic power transmission targeted at specific devices based on their operational needs. Power is transmitted in cycles or intervals to devices that require it, allowing other devices to enter low-power states, thereby maintaining device reliability through periodic charging while significantly improving overall energy efficiency.

AI summary
A building management system of a building including one or more computer-readable storage media having instructions that cause the one or more processors to operate a wireless power transmitter to transmit wireless power to one or more first building devices located within a zone of the building. The instructions cause the one or more processors to receive an indication of a zone power mode for the zone and operate the wireless power transmitter to switch from transmitting the wireless power to the one or more first building devices to transmitting the wireless power to one or more second building devices located within the zone of the building, wherein the one or more second building devices are indicated by the zone power mode, wherein at least one building device of the one or more second building devices is a different building device than the one or more first building devices.
