Modular Emergency Light Bar With Interchangeable Lighting Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Emergency vehicle light bars lack flexibility in configuring different light directional capabilities without using rotating elements, limiting their effectiveness in alerting traffic and providing adequate visibility during emergencies.
Innovation Solution
A light bar base with end sections and a central recess that can interchangeably receive various center section lighting modules with different shapes and sizes, secured using quick-release mechanical and electrical connections, allowing for customizable light bar assemblies without the need for tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed light bar configuration is used, then the structure is simple and reliable, but the light directional capabilities are limited and cannot be customized for different emergency situations
Solution Approach 1:
The light bar is divided into multiple interchangeable modules, each with different light directional capabilities. These modules can be independently selected and attached to the base unit, allowing customization of light patterns without redesigning the entire system. The segmentation enables flexible configuration while maintaining a simple base structure.
Solution Approach 2:
The base unit is designed with a universal mounting interface that can accommodate various types of lighting modules. This multi-functional design allows a single base unit to support multiple light configurations, providing adaptability for different emergency situations without requiring multiple specialized light bar units.
2Adaptability or versatility
If rotating elements are used to change light direction, then light directional capabilities are enhanced, but the device complexity and reliability are reduced due to moving parts
Solution Approach 1:
Instead of rotating existing lights to change direction, the system dynamically changes light direction by swapping between different stationary modules. Each module is fixed in position with its specific light directional capability, eliminating the need for rotating mechanisms while maintaining the ability to adapt light patterns for different situations.
3Strength
If tool-secured modules are used, then the light bar structure is more stable, but the ease of operation and quick configuration is reduced
Solution Approach 1:
The traditional tool-based mechanical fastening system is replaced with a quick-release latching mechanism. This new mechanical system provides sufficient attachment stability through engineered latch engagement while allowing modules to be installed and removed quickly by hand, eliminating the need for tools and significantly improving ease of operation.

AI summary
A modular light bar, for mounting on an emergency vehicle, is configured for changing of a portion of its external shape for changing a corresponding light directional capability thereof using interchangeable lighting modules. The lights thereon cast light in multiple lighting directions without using any rotating elements. The modular light bar includes: a base member with a first light bar end section and a second light bar end section interconnected by a support portion configured to provide a gap between the first and second light bar end sections. Various different center section lighting modules may be interchangeably received in the gap between the first light bar end section and the second light bar end section, and be latched thereto.
