Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Emergency response vehicles face challenges in efficiently and cost-effectively integrating and retrofitting advanced communications and response equipment due to the labor-intensive and costly process of installing and removing various systems across multiple frequency bands and protocols, which hinders quick adaptation to different emergency situations and reduces the vehicles' resale value.
Innovation Solution
A self-contained emergency device integrated into a light bar, equipped with a fuel cell for power, wireless communication modules, and a control interface, which can be easily mounted on vehicles and connected to a broadband network, eliminating the need for extensive wiring and allowing for quick deployment and adaptation of equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If emergency vehicles are equipped with multiple communications systems and equipment for detecting and responding to emergencies, then the emergency response capabilities are improved, but the vehicle interior space becomes crowded and the installation process becomes labor-intensive
Solution Approach 1:
The patent segments the emergency response equipment into a modular light bar assembly that functions as an integrated unit. The light bar includes multiple light sources for different emergency scenarios, wireless communication modules, and power management systems all contained within a single mountable structure, eliminating the need for separate installations of each communication and response system throughout the vehicle interior.
Solution Approach 2:
The patent combines multiple previously separate systems into a unified light bar assembly. This includes merging emergency lighting functions, wireless communication capabilities (WiFi, Bluetooth, cellular), power management, and control interfaces into a single integrated unit that mounts on the vehicle exterior, thereby improving emergency response capabilities while reducing interior complexity.
2Adaptability or versatility
If vehicles are retrofitted with advanced equipment through a labor-intensive process, then the emergency response equipment is updated, but the time and cost for installation and removal increases
Solution Approach 1:
The light bar assembly is designed and pre-configured as a complete, self-contained unit before installation. All communication modules, lighting systems, and power management components are integrated and tested in advance, allowing for rapid deployment as a single assembly rather than requiring step-by-step installation of individual systems, thereby significantly reducing installation and removal time.
Solution Approach 2:
The patent implements a dynamic, reconfigurable light bar assembly where components can be easily added, removed, or replaced based on specific emergency response needs. The modular design allows the system to adapt to different operational requirements without requiring complete reinstallation, enabling quick updates to equipment capabilities.
3Use of energy by moving object
If power cables are routed through the roof lining and side posts to connect equipment, then the equipment is powered, but the vehicle structure is compromised and resale value decreases
Solution Approach 1:
The patent extracts the power supply system from the vehicle's internal electrical infrastructure and integrates it directly into the light bar assembly through fuel cell modules and solar panels. This eliminates the need to route power cables through the roof lining and side posts, as the light bar becomes a self-powered unit that draws no electrical current from the vehicle, thereby preserving structural integrity and resale value.
Solution Approach 2:
The light bar assembly incorporates self-service power generation capabilities through integrated fuel cell modules and solar panels. The system manages its own power requirements independently, generating and storing energy locally without relying on the vehicle's electrical system. This self-sufficiency eliminates the need for structural modifications to accommodate power cable routing.
4Illumination intensity
If light bars generate electromagnetic noise, then the emergency lighting function is achieved, but the sensitive telecommunications equipment inside the vehicle is interfered with
Solution Approach 1:
The patent relocates the light bar assembly from the vehicle interior to the exterior, mounting it on the roof or other external surfaces. This spatial separation places the electromagnetic noise-generating lighting components outside the vehicle cabin, eliminating interference with sensitive telecommunications equipment while maintaining full emergency lighting visibility. The external mounting creates a physical dimension that resolves the electromagnetic compatibility issue.

AI summary
An emergency system for a vehicle integrates many disparate equipment into single housing, including the power supply for the equipment. In one embodiment of the invention, the emergency system is a light bar. The light bar houses a power source comprising solar cell panels, a Lithium-Ion battery pack and a connection to an external supply such as the vehicle's electrical power. Energy for operating the light bar is provided by one or more of the power sources, depending on operating conditions of the light bar and each of the power sources.
