Vehicle Lighting Control Apparatus Proximity-Based Interior Exterior Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting control systems for vehicles primarily focus on illuminating the exterior environment based on distance, neglecting the need to control lighting states for both interior and exterior conditions simultaneously, limiting users' ability to assess various conditions around and inside the vehicle.
Innovation Solution
A lighting control apparatus and method that includes a distance acquiring unit and a lighting control unit to manage the lit states of multiple lighting units on a vehicle, such as room lights, under lights, guide lights, and headlights, based on the distance from a communication terminal, ensuring appropriate illumination of both the vehicle's interior and exterior environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only one kind of lighting is turned on depending on the distance between the vehicle and the mobile device, then the lighting control system is simple, but the user cannot check various conditions such as the condition inside the vehicle and the surrounding road condition simultaneously
Solution Approach 1:
The patent segments the lighting control into multiple independent lighting units (first lighting unit for interior, second lighting unit for exterior) that can be controlled separately based on distance thresholds. This allows each lighting unit to serve specific functions while maintaining overall system manageability through modular control logic.
Solution Approach 2:
The patent implements dynamic lighting control where the lit states of different lighting units change automatically based on the real-time distance between the mobile device and the vehicle. The system transitions between different lighting configurations as the user approaches or moves away, providing adaptive illumination without manual intervention.
2Loss of information
If multiple lighting units are controlled according to distance, then the user can check various conditions inside and outside the vehicle, but the lighting control system becomes more complex
Solution Approach 1:
The patent applies local quality by assigning different lighting units to illuminate specific areas (interior vs. exterior) based on the user's distance from the vehicle. Each lighting unit provides targeted illumination for its designated zone, ensuring that the user receives appropriate visual information for the current context without requiring all lights to be on simultaneously.
Solution Approach 2:
The patent utilizes parameter changes by establishing multiple distance thresholds that trigger different lighting configurations. As the distance parameter changes, the system automatically adjusts which lighting units are active, creating a stepped response that provides comprehensive visibility while maintaining control simplicity through predefined thresholds.
3Ease of operation
If the lighting control apparatus controls both interior and exterior lighting based on distance, then the usability is enhanced, but the energy consumption increases
Solution Approach 1:
The patent implements partial action by activating only the necessary lighting units based on the user's distance from the vehicle. When the user is far away, only exterior lighting is activated for approach guidance. When the user is close, interior lighting is activated for cabin inspection. This selective activation provides sufficient illumination for each scenario while minimizing overall energy consumption compared to activating all lights simultaneously.
Solution Approach 2:
The patent employs periodic action through sequential lighting activation based on distance thresholds. As the user approaches the vehicle, different lighting units are activated in sequence (exterior first, then interior), creating a time-based progression of illumination that matches the user's approach pattern while reducing total energy usage compared to continuous full illumination.
