Building system control utilizing building occupancy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current home and office automation systems rely on fiducial elements, such as smartphones, to communicate with humans, limiting their ability to initiate actions based on human presence and requiring binary on-off responses, which is inefficient and insecure, especially in detecting multiple humans or children without smartphones.
Innovation Solution
The system uses Network Presence Sensing technology to detect human presence within a structure without relying on fiducial elements, allowing for proactive communication and action based on occupancy, differentiating multiple humans and tracking their movements to adjust environmental controls and security systems accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fiducial elements like smartphones are used to communicate with humans, then the system can identify and interact with users, but it cannot effectively detect human presence without the fiducial element and requires binary on-off responses
Solution Approach 1:
The patent extracts the fiducial element (smartphone) from the interaction loop and replaces it with direct human presence detection using sensors. The system no longer requires the smartphone as an intermediary to detect presence,而是 uses motion detectors, temperature sensors, and other environmental sensors to directly sense human occupancy and characteristics.
Solution Approach 2:
The patent introduces environmental sensors as intermediaries between humans and the control system. These sensors detect human presence, temperature, motion, and other characteristics, translating physical human attributes into data that the control system can use to make nuanced decisions about environmental adjustments.
2Device complexity
If the system relies on binary on-off responses, then the control logic is simple, but energy efficiency and security are compromised due to inability to detect multiple humans or children
Solution Approach 1:
The patent transforms the static binary on-off control into a dynamic system that continuously monitors multiple parameters (presence, temperature, motion patterns) and adjusts controls accordingly. The system adapts its behavior based on real-time sensor data, creating a more responsive and reliable control mechanism.
Solution Approach 2:
The patent implements feedback loops where sensors continuously monitor environmental conditions and human presence, and the control system adjusts settings based on this feedback. This creates a closed-loop system that can detect multiple humans, distinguish between different occupancy patterns, and make informed decisions about energy usage and security.
3Ease of operation
If smartphones are used as the primary interface, then users can control systems remotely, but screen time increases and accessibility is limited for those without smartphones
Solution Approach 1:
The patent enables the environment to serve itself by automatically detecting human presence and adjusting controls without requiring user initiation through a smartphone interface. The system proactively responds to human occupancy, eliminating the need for users to spend time operating screens while maintaining accessibility for all individuals regardless of smartphone usage.
