Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current building automation systems lack effective means to provide real-time emergency information to emergency personnel during fire situations, hindering their ability to navigate and respond efficiently within a structure.
Innovation Solution
The integration of wireless emergency devices and automation components within a building automation system, utilizing IEEE 802.15.4/ZigBee protocols, enables the communication of emergency information to a heads-up display, providing critical data such as temperature, air quality, and location information to emergency responders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If building automation systems use traditional wired communication infrastructure, then system reliability is improved, but installation complexity and cost increase
Solution Approach 1:
The patent replaces the mechanical wired communication system with a wireless communication system using IEEE 802.15.4/ZigBee protocols. Emergency devices and automation components communicate via wireless signals, eliminating the need for physical wiring while maintaining communication reliability. This substitution resolves the contradiction by removing installation complexity while preserving the essential communication function.
2Loss of information
If emergency information is provided through traditional display methods, then information delivery is achieved, but emergency personnel's situational awareness and response efficiency are hindered
Solution Approach 1:
The patent introduces a heads-up display (HUD) that projects emergency information directly into the emergency personnel's field of view. This moves information delivery from traditional external displays to an overlay dimension within the user's visual field, allowing simultaneous awareness of the environment and critical data. This dimensional change enhances situational awareness and response efficiency without compromising information delivery.
3Ease of manufacture
If wireless communication protocols like IEEE 802.15.4/ZigBee are used, then installation cost is reduced, but communication range and reliability may be limited
Solution Approach 1:
The patent implements mesh networking topology where emergency devices and automation components act as relay nodes. Information is pre-routed through multiple potential paths before transmission is needed. If one path fails, alternative paths are already established, providing redundant communication routes that maintain reliability while using low-cost wireless protocols.
Data Source
AI summary
An emergency device or emergency system is configured for operation within a fire safety system, or a fire safety portion of a building automation system (BAS). For example, wireless devices, emergency devices and/or automation components within the fire safety system, or the fire safety portion of the BAS may be configured to automatically provide or otherwise communicate emergency information to an emergency device or system. The emergency information may, in turn, be utilized by emergency personnel or first responders to determine conditions with the structure. A heads-up display is configured to present the display data based on the received emergency communication to a user.
