Vehicle Door Handle Illumination for Security Status Without Glare
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle door handles lack effective illumination solutions that provide clear indication of the vehicle's security system status and enhance visibility in low ambient lighting conditions, often resulting in glare or bright spots.
Innovation Solution
A door handle assembly with an integrated illumination module featuring a light emitting diode (LED) or electroluminescent light source that backlights a security icon, providing enhanced visibility and customizable lighting options, including color schemes that match the vehicle's interior and exterior lighting, and can be activated by touch or remote keyless entry systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional lighting devices are used to illuminate the side of the vehicle, then security lighting and convenience lighting are provided, but glare or bright spots are created at the side of the vehicle
Solution Approach 1:
The patent applies local quality by directing light specifically to the door handle area rather than providing broad side illumination. The housing includes a light directing portion with features like reflective surfaces, refractive elements, or asymmetric beam patterns that concentrate light where needed (on the door handle and immediate surroundings) while preventing light from reaching areas where it would create glare (driver's eyes, passenger areas). This localized approach maintains necessary illumination intensity while eliminating harmful glare effects.
2Illumination intensity
If illumination is added to the door handle assembly, then visibility in low ambient lighting conditions is enhanced, but device complexity increases
Solution Approach 1:
The patent merges the illumination function with the existing door handle assembly by integrating the light source, housing, and light directing portion into a single unified component structure. Rather than adding a separate lighting system, the illumination device is combined with the door handle components, allowing the housing to serve dual purposes as both structural support and light directing element. This integration approach enhances visibility while minimizing the increase in overall device complexity.
Solution Approach 2:
The housing of the illumination device is designed to perform multiple functions: it provides structural support for the light source, directs light to appropriate areas, and integrates with the existing door handle assembly. The light directing portion may also serve aesthetic functions by coordinating with the vehicle's lighting schemes. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity while achieving enhanced visibility.

AI summary
A vehicular communication system includes a near field communication device disposed at a vehicle. Responsive to a near field communication-enabled device being within a threshold distance of the vehicle, the near field communication device wirelessly receives a wakeup near field communication from the near field communication-enabled device. Responsive to the near field communication device wirelessly receiving the wakeup near field communication from the near field communication-enabled device, the near field communication device (i) wakes up and (ii) determines whether the near field communication-enabled device is an authorized device. Responsive to determining that the near field communication-enabled device is an authorized device, the near field communication device authenticates the near field communication-enabled device. Responsive to authentication of the near field communication-enabled device, and with the near field communication-enabled device being within the threshold distance to the vehicle, an electrically operable accessory of the vehicle is electrically operated.
