Vehicle Antenna Assembly Rotating Wire Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Micro type antennas for vehicles face manufacturing inefficiencies due to differing connector directions when mounted on the left or right side of a vehicle's roof, leading to productivity issues.
Innovation Solution
An antenna assembly with a rotating wire connector and rotating pin that allows the direction of the power wire connection to be varied by 180 degrees, enabling uniform manufacturing and installation on either side of the roof.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If micro type antenna is mounted on left or right side of roof, then receiving performance is improved, but connector direction varies causing manufacturing inefficiency
Solution Approach 1:
The wire connector is designed with rotational capability around a rotating pin, allowing it to dynamically change its extending direction. This dynamic adjustment enables the connector to adapt to different mounting positions (left or right side of roof) while maintaining uniform manufacturing processes, as the connector can be oriented after assembly to match the required connection direction.
2Reliability
If micro type antenna is used instead of glass type, then receiving performance is improved, but connector orientation complexity increases
Solution Approach 1:
The wire connector incorporates a rotating pin mechanism that allows it to change its extending direction dynamically. This dynamic feature simplifies the overall device complexity by providing a single standardized connector design that can adapt to different mounting orientations, rather than requiring multiple specialized connector variants for different positions.

AI summary
An antenna assembly for a vehicle may include: a cover into which a lower end portion of an antenna is inserted; a base coupled to a lower side of the cover to form an internal compartment; a circuit board mounted on an upper surface of the base to be connected to the lower end portion of the antenna; a terminal mounted to the base wherein an upper end portion thereof is connected to the circuit board and a lower end portion thereof penetrates into the base; a wire connector disposed at the lower end portion of the terminal to be connected to a power wire; and a rotating pin coupling the wire connector with the terminal, wherein the wire connector may be rotatable about the rotating pin.
