Frunk Lighting System with Rotating Lamp Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicles, especially electric vehicles, lack a hood lighting system that can generate a light-emitting effect for the front emblem and illuminate the frunk space, hindering aesthetic design and visibility in future motorized vehicles.
Innovation Solution
A frunk lighting system with a motor-driven rotating mechanism that changes the illuminating direction of a lamp from the front emblem to the frunk space as the hood opens, utilizing a motor, rotating gear, and LED light sources, allowing for automatic switching between hood closing and opening states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a hood lighting system is added to illuminate both the emblem and frunk space, then the aesthetic design and visibility are improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent implements a rotatable lamp assembly that can dynamically change its illuminating direction between the emblem and frunk space. The lamp assembly is connected to a rotating mechanism driven by a motor, allowing it to switch between different lighting positions based on whether the hood is closed or open, thereby providing dynamic lighting adaptation without requiring separate lighting systems for each function
Solution Approach 2:
The single lamp assembly serves multiple functions by illuminating both the emblem (when hood is closed) and the frunk space (when hood is open). This multi-functional design eliminates the need for separate lighting systems for aesthetic illumination and functional illumination, reducing overall system complexity while maintaining both aesthetic and visibility requirements
2Adaptability or versatility
If separate lighting systems are used for emblem illumination and frunk illumination, then the lighting functionality is improved, but the manufacturing cost and device complexity increase
Solution Approach 1:
The patent employs a single lamp assembly that can illuminate both the emblem and frunk space by changing its orientation. This universal lighting component replaces what would traditionally require two separate lighting systems, thereby reducing manufacturing costs while maintaining full lighting functionality for both aesthetic and practical purposes
Solution Approach 2:
The patent combines the emblem lighting function and frunk lighting function into a single integrated lamp assembly. By merging these two lighting functions into one component that can rotate between positions, the system achieves the versatility of multiple lighting functions while simplifying the overall structure and reducing manufacturing complexity

AI summary
A frunk lighting system applied to a vehicle is mounted on a hood provided with an emblem on a front of the vehicle to cover or open a space of a frunk, and has an illuminating direction of light emitted by a light source changed into lighting for the emblem and lighting for the frunk by movement of a rotating mechanism connected to a motor whose rotating direction is changed by a closing signal and an opening signal of the hood, thereby easily implementing an appearance design suitable for a future motorized vehicle with a light-emitting effect for the front emblem of the vehicle, and particularly, automatically switches the lighting, which has illuminated the emblem in a state where the hood is closed, toward the frunk to illuminate a frunk space, thereby maximizing visibility and usability of the frunk.
