Occupancy Sensor Power Unit for Work Pod Energy Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Isolated work areas, such as work pods, face challenges in efficiently managing energy consumption as existing systems do not effectively de-activate lighting, ventilation, and electrical power outlets when unoccupied, leading to unnecessary energy usage.
Innovation Solution
An electrical power and data unit with an environmental sensor and timer that selectively energizes and de-energizes components based on occupancy detection, including a manual override switch and wire pass-through for flexible connectivity, to conserve energy by automatically de-activating systems when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If lighting, ventilation, and electrical power outlets remain continuously active in isolated work areas, then users have immediate access to these services, but energy is wasted when the areas are unoccupied
Solution Approach 1:
The system uses occupancy sensors to detect whether a work area is occupied or unoccupied, and this feedback signal automatically controls the lighting, ventilation, and power outlets to turn on or off accordingly. This eliminates energy waste while ensuring services are available when needed.
Solution Approach 2:
The work area system automatically manages its own energy consumption by using occupancy detection to control its components without requiring manual user intervention. The system self-adjusts based on whether users are present, eliminating the need for users to manually switch services on or off.
2Loss of energy
If automated occupancy-based control is implemented, then energy consumption is reduced, but system complexity increases
Solution Approach 1:
The control unit is designed to manage multiple functions (lighting, ventilation, power outlets) through a single automated occupancy-based control mechanism. This multi-functional approach reduces overall system complexity compared to having separate control systems for each component.
3Adaptability or versatility
If manual override switches are added for user control, then user flexibility is improved, but device complexity increases
Solution Approach 1:
The manual override switches are integrated into the same control unit that houses the automated occupancy-based control. This merging of automated and manual control mechanisms into a single unit provides user flexibility while minimizing the increase in overall device complexity through shared housing and control circuitry.

AI summary
An electrical power or electronic data unit is provided for mounting in an isolated work space such as a work pod that is at least partially enclosed by walls or other surfaces. The unit includes a housing body, an electrical power outlet and/or an electronic data connector, and an occupancy sensor that is in communication with a controller. The controller is operable to energize and de-energize a lighting or ventilation system associated with the isolated work space in response to a signal received from the occupancy sensor, and may further be operable to energize and de-energize the power outlet or data connector. Optionally, an environmental sensor is provided with the unit, and is in communication with a building automation system.
