Grab Handle Lamp Lighting Modes for Vehicle Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grab handle lighting devices in vehicles primarily function as position indicators or simple illuminators, failing to provide comprehensive information about vehicle conditions to users.
Innovation Solution
A lighting device for a vehicle grab handle that incorporates a lamp capable of multiple lighting modes, controlled by a key sensor and door sensors, to display user approach, lock/unlock, and open/close information, as well as drive mode and surrounding object detection, enhancing its role as an information presentation device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the lamp is used only as a position indicator or simple illuminator, then the device structure remains simple, but the information presentation capability is insufficient
Solution Approach 1:
The lamp embedded in the grab handle is designed to perform multiple functions: position indication, illumination, and information presentation about vehicle conditions. By making the lighting system universal, the patent resolves the contradiction by enabling rich information display without adding separate dedicated devices, thus improving information capability while keeping the overall system relatively simple.
Solution Approach 2:
The patent combines the lighting function with the grab handle structure, integrating the lamp into the existing grab handle assembly. This merging approach allows the lighting system to serve multiple purposes (position indication, illumination, and vehicle status display) without requiring a completely separate system, thereby reducing overall complexity while enhancing information presentation.
2Adaptability or versatility
If multiple sensors and control functions are added to the grab handle, then the information presentation capability is enhanced, but the device complexity increases
Solution Approach 1:
The lighting controller is designed to respond to multiple different inputs (key sensor, door lock sensor, door open/close sensor) and provide appropriate lighting responses for each. This multi-functional control approach allows the system to adapt to various vehicle conditions and user scenarios without requiring separate control systems for each function, thereby enhancing versatility while managing complexity through a unified control architecture.
Solution Approach 2:
Multiple sensing functions (key detection, door lock status, door open/close status) are merged into a single integrated control system that manages all lighting modes from one controller. This consolidation allows the system to handle diverse inputs and provide adaptable lighting responses without the complexity of multiple independent control systems, resolving the contradiction between versatility and complexity.
3Loss of information
If the lamp provides comprehensive vehicle condition information, then user awareness is improved, but the lighting control complexity increases
Solution Approach 1:
Different lighting modes provide different types of information tailored to specific vehicle conditions: first lighting mode for key detection, second mode for door lock status, third mode for door open/close status. This local quality approach allows each lighting mode to be optimized for its specific information presentation purpose, making the control logic more manageable by breaking down comprehensive information presentation into distinct, condition-specific modes rather than requiring a single complex control system.
Solution Approach 2:
The lighting control is segmented into distinct modes, each triggered by specific sensor inputs and providing specific information. This segmentation of the control logic into manageable, condition-specific modes simplifies the overall control complexity while still providing comprehensive vehicle status information, as each mode can be independently designed and controlled based on its specific triggering condition and information purpose.

AI summary
A lighting device for a grab handle in a vehicle includes the grab handle disposed in a passenger compartment, a lamp embedded in the grab handle, a key sensor capable of detecting an approach of a user having a key into a given range around the vehicle, and a lighting controller configured to control lighting mode of the lamp. The lighting controller controls the lamp [1] to light the lamp in a first lighting mode when user's approach information is input to the lighting controller, [2] to light the lamp in a second lighting mode when lock/unlock information of a door is input to the lighting controller, or [3] to light the lamp in a third lighting mode when open/close information of the door is input to the lighting controller.
