Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle approach lighting systems are static and lack a dynamic, stylistic element, failing to enhance the visual appeal of vehicles.
Innovation Solution
A vehicle lighting system that includes a projector coupled to a side structure or door, equipped with a sensor to detect approaching individuals and project a dynamic light pattern onto the ground, creating an illuminated path that adjusts based on the person's location, simulating a 'red carpet' effect or aligning with their approach direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If static lighting solutions like puddle lamps are used, then the lighting system is simple to implement, but the appearance is dull and lacks dynamic styling
Solution Approach 1:
The lighting system transitions from static puddle lamps to a dynamic projector-based system that can change light patterns, intensity, and direction. The projector dynamically adjusts the illuminated path based on detected person location and approach direction, creating a living, adaptive lighting experience that enhances visual appeal while maintaining reasonable system complexity.
Solution Approach 2:
The system changes multiple lighting parameters including intensity, pattern shape, direction, and color temperature based on detected conditions. The projector can vary these parameters in real-time to create different ambient effects and stylistic elements, transforming the dull static light into an engaging dynamic display.
2Illumination intensity
If a dynamic lighting system with person detection is implemented, then the visual appeal and stylistic element are enhanced, but the device complexity increases
Solution Approach 1:
The lighting system performs multiple functions: it provides basic illumination, detects person presence and location, tracks approach direction, dynamically adjusts light patterns, and creates stylistic effects. By consolidating these functions into an integrated system with a projector and sensor, the patent achieves high visual appeal while managing complexity through multi-functionality rather than separate dedicated components for each function.
Solution Approach 2:
The lighting system automatically detects persons and adjusts its own operation without manual control. The sensor continuously monitors the environment, and the projector autonomously modifies light patterns based on detected parameters, making the system self-regulating and reducing the need for complex manual control mechanisms.
3Adaptability or versatility
If the light pattern shifts to align with approach direction, then the adaptability to user movement is improved, but the control system complexity increases
Solution Approach 1:
The system continuously detects person location and approach direction, using this feedback to dynamically adjust the light pattern orientation. The sensor provides real-time positional data, and the control system processes this information to shift the illuminated path accordingly, creating a responsive adaptive system that follows the person's movement while maintaining manageable control complexity through continuous feedback loops.

Data Source
AI summary
A lighting system of a vehicle is provided herein. A projector is coupled to a side structure of the vehicle. A sensor detects a remote device carried on a person approaching the vehicle. Based on a detected location of the remote device relative to the vehicle, the projector projects a light pattern onto a ground surface to define an illuminated path leading up to the vehicle and pointing towards the person.
