Vehicle Multimedia Jack with Integrated LED Lighting and Reflector
Solution Overview
Problem
Conventional multimedia jacks for vehicles lack effective lighting to distinguish ports and terminals at night, leading to increased manufacturing costs when separate lighting is added, and existing solutions result in non-uniform illumination.
Innovation Solution
A multimedia jack with a housing, terminal part, and cover part incorporating a light emitting diode (LED) lighting apparatus, where the light is directed through a connection receptacle display part and character display part, and the cover part includes a reflector to enhance visibility, with power and brightness control interworking with vehicle systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a separate lighting apparatus is added to the multimedia jack to improve night visibility, then illumination is provided, but material costs and manufacturing costs increase
Solution Approach 1:
The patent integrates the lighting apparatus directly into the multimedia jack structure, merging the lighting function with the existing jack components. The lighting apparatus is positioned within the housing to illuminate the connection receptacles, eliminating the need for separate external lighting devices and reducing overall manufacturing costs while maintaining effective night visibility
Solution Approach 2:
The multimedia jack is designed to serve multiple functions: it provides multimedia connectivity through USB and AUX ports while simultaneously incorporating a lighting apparatus that illuminates the connection areas. This multi-functional design allows a single component to fulfill both connectivity and illumination needs, reducing the need for additional separate devices
2Illumination intensity
If a lighting apparatus is installed in the body to allow light leakage through insertion receptacles, then visibility is improved, but light distribution is non-uniform with some portions bright and others dark
Solution Approach 1:
The patent employs a reflector positioned within the housing to redirect and distribute light from the lighting apparatus to specific areas. The reflector is strategically placed to ensure uniform illumination across all connection receptacles and the terminal display area, addressing the non-uniform lighting issue by locally adjusting light distribution to achieve consistent brightness throughout the multimedia jack interface
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Provides uniform lighting to enhance user convenience at night, allowing clear distinction of ports and terminals while controlling power and brightness simultaneously, reducing manufacturing costs and improving illumination uniformity.
Implementation Method 1
a terminal part mounted at an inner side of the housing and including a multimedia port and a light emitting diode (LED) lighting apparatus
Implementation Method 2
the cover part may include a reflector disposed at an inner side thereof so as to be coupled thereto, and the connection receptacle display part may be formed by exposing a portion of the reflector through the connection receptacle

AI summary
Disclosed herein is a multimedia jack for a vehicle with a lighting apparatus, including: a housing with an opening part; a terminal part, mounted on an inner side of the housing, with a multimedia port and a light emitting diode (LED) lighting apparatus; a cover part covering the opening part of the housing and including a connection receptacle disposed at a position corresponding to the multimedia port so as to be connected to the multimedia port; and a connection receptacle display part disposed around the connection receptacle, wherein light of the LED lighting apparatus is irradiated through the connection receptacle display part. Therefore, it is possible to increase user convenience at night by uniform lighting of the multimedia jack and control power and brightness by interworking with other apparatuses in the vehicle.
