Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional light bars are used, then illumination is provided, but electromagnetic interference (EMI) and radio-frequency interference (RFI) are emitted causing harmful effects
Solution Approach 1:
The patent applies electromagnetic shielding materials to block harmful EMI and RFI emissions from the LED light bar while allowing the beneficial illumination function to continue. The shielding converts the harmful electromagnetic emissions into a controlled environment, preventing interference with other electronic devices while maintaining the light bar's illumination capability.
2Illumination intensity
If traditional light bars are used, then illumination is provided, but heat dissipation is insufficient causing overheating
Solution Approach 1:
The patent introduces heat dissipation fins and thermally conductive materials as intermediary structures between the LED light sources and the surrounding environment. These intermediaries facilitate efficient heat transfer from the LEDs to the air, preventing overheating while maintaining continuous illumination operation.
3Illumination intensity
If traditional single-bar light bars are used, then illumination is provided, but adjustability and installation flexibility are limited
Solution Approach 1:
The patent divides the light bar into multiple adjustable segments or sections that can be independently positioned and angled. This segmentation allows each section to be adjusted to optimal viewing angles while maintaining overall illumination coverage, significantly improving installability and adaptability to different vehicle configurations.
4Illumination intensity
If traditional light bars are used, then illumination is provided, but durability and reliability degrade over time
Solution Approach 1:
The patent incorporates protective shielding, sealed housings, and corrosion-resistant materials in advance to protect the LED light bar from environmental damage, vibration, and moisture. These preemptive protective measures ensure long-term durability and reliability by preventing degradation before it occurs, allowing continuous operation without maintenance.

AI summary
A lighting assembly for use with a vehicle includes a light bar having a one or more circuit boards positioned within one or more housings wherein each circuit board includes light emitting diodes (LEDs) mounted to a surface thereof. The light bar may be divided into portions wherein each portion has its own housing. The light bar is operationally connected to an electronic control unit (ECU), wherein the ECU controls operation of the light bar and its components. The ECU is operationally connected to an electrical system of the vehicle such that the ECU can receive signals, commands, and/or information from the vehicle. The ECU is adapted to control the light bar, including illumination of LEDs thereon, based on the signals, commands, and/or information from the vehicle. The ECU is further adapted to emit and/or control audio output based on the signals, commands, and/or information from the vehicle.
