Vehicle Lamp Antenna Integration for Trailer Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle antenna systems, typically mounted on the roof, have limited range and are obstructed by vehicle surfaces, leading to inadequate wireless communication between vehicle and trailer electronic devices, especially when the trailer is positioned behind the vehicle.
Innovation Solution
Integrating a primary antenna into the vehicle lamp, such as a tail lamp, with a conductive structure that adjusts operating parameters, and positioning it at the rearmost corner to minimize distance and obstructions, enhancing signal range and coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna is mounted on the roof of the vehicle, then the antenna has a relatively stable position, but the wireless communication range is limited and signal strength is reduced due to obstructions from vehicle surfaces
Solution Approach 1:
The patent relocates the antenna from a traditional roof-mounted position to an integrated position within the vehicle lamp assembly, specifically utilizing the rear lamp housing. This spatial repositioning places the antenna at the rearmost corner of the vehicle, extending the effective communication range backward toward the trailer while eliminating obstructions from the vehicle body surface. The lamp housing serves as a new mounting dimension that provides both aesthetic integration and improved signal propagation.
Solution Approach 2:
The conductive structure within the lamp housing serves as an intermediary element that performs dual functions: it provides the stylized aesthetic appearance desired by customers and simultaneously functions as the antenna structure for wireless communication. This intermediary component resolves the conflict between aesthetic requirements and communication performance by combining both functions into a single integrated element.
2Length of moving object
If the antenna is positioned at the rearmost corner of the vehicle, then the distance to the trailer is minimized and obstructions are reduced, but the antenna integration complexity increases
Solution Approach 1:
The patent merges the antenna function with the existing lamp housing structure and conductive elements. Rather than adding a separate antenna component, the design utilizes the lamp housing's conductive structure to serve as the antenna element. This consolidation eliminates the need for additional mounting hardware, wiring, and assembly steps, thereby reducing integration complexity despite the innovative positioning.
Solution Approach 2:
The conductive structure in the lamp housing performs multiple functions simultaneously: it provides the stylized aesthetic appearance, serves as the antenna for wireless communication, and utilizes the existing structural framework of the lamp assembly. This multi-functionality reduces the need for separate components and simplifies the overall integration process.
3Shape
If a metallic layer is added to the stylized component for aesthetic purposes, then the visual design is enhanced, but the antenna performance may be affected
Solution Approach 1:
The patent carefully controls the parameters of the metallic layer, including its thickness, material composition, and electrical conductivity, to ensure it maintains aesthetic appearance while allowing sufficient electromagnetic signal transmission. By optimizing these parameters, the metallic layer provides the desired chrome or metallized look without creating excessive signal reflection or attenuation that would degrade antenna performance.
Solution Approach 2:
The metallic layer is applied selectively to specific portions of the lamp housing rather than uniformly across the entire structure. This localized application allows the antenna to function in regions where signal transmission is critical while providing aesthetic enhancement in visible areas, thereby resolving the conflict between appearance and performance through spatial differentiation of material properties.
