Solution Overview
Problem
Emergency vehicles require improved lighting systems that enhance safety, visibility, and aesthetics while providing effective warnings and directional indications, which existing systems fail to adequately address.
Innovation Solution
A vehicle notification system featuring a light generating layer with LEDs in semiconductor ink on the decklid, activated by signals from a decklid ajar indicator and emergency lighting module, or turn indicator, to emit directional instructions and alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional lighting systems are used for emergency vehicles, then the system structure is simple, but the visibility, safety, and warning capabilities are insufficient
Solution Approach 1:
The lighting system is segmented into multiple independent LED modules arranged in alternating color segments (e.g., red and blue segments). Each segment can be independently controlled to provide different warning patterns and directional indications, enhancing visibility while maintaining manageable system complexity through modular design
Solution Approach 2:
The lighting system incorporates dynamic control capabilities with a controller that can selectively activate different LED segments based on vehicle status signals (decklid ajar indicator, turn indicator, emergency lighting module). The system provides dynamic lighting patterns including alternating colors, directional indications, and responsive warnings that adapt to different operational conditions
2Adaptability or versatility
If multiple lighting functions are integrated into the decklid, then the warning capabilities and safety are improved, but the device complexity increases
Solution Approach 1:
The decklid lighting system is designed as a multi-functional universal platform that performs multiple warning and indication functions through a single integrated structure. The system responds to various inputs (decklid ajar indicator, turn indicator, emergency lighting module) and provides multiple outputs (directional indications, warning lights, alternating color patterns) from one unified lighting assembly, reducing the need for separate lighting systems
3Illumination intensity
If alternating color segments are used in the lighting layer, then the aesthetic appeal and visibility are enhanced, but the manufacturing complexity increases
Solution Approach 1:
The light generating layer is divided into alternating color segments (e.g., red and blue portions) that can be manufactured as separate LED modules and then assembled in an alternating pattern on the decklid. This segmentation allows for standardized manufacturing of individual segments while achieving the aesthetic alternating color effect when installed, balancing visual appeal with manufacturing feasibility
