Solution Overview
Problem
Existing vehicle-to-X communication systems face challenges in being installed and adjusted on various vehicle bodies and shapes, particularly due to space constraints and the need for extensive adaptations, limiting flexibility in signal radiation and coverage.
Innovation Solution
A vehicle-to-X communication system comprising two communication modules with integrated antennas oriented in different directions, allowing for flexible installation and adjustment of signal radiation and coverage, independent of vehicle body shape, using a modular design with a first and second communication module connected via a bidirectional interface, such as a CAN bus system, enabling independent operation and data processing.

Engineering Contradiction Analysis
1Adaptability or versatility
If a smart antenna with integrated electronic components is used, then signal radiation and coverage can be adjusted, but the available installation space is strictly limited and extensive adaptations to each vehicle body are required
Solution Approach 1:
The antenna system is divided into multiple independent antenna elements (first antenna, second antenna, third antenna) with different communication angles. Each antenna can be independently positioned and oriented within the vehicle interior, allowing flexible coverage adjustment without requiring a single complex integrated antenna structure.
Solution Approach 2:
The patent transitions from traditional external antenna mounting to internal vehicle antenna placement. By utilizing the three-dimensional space inside the vehicle cabin and positioning antennas at different locations (dashboard, ceiling, doors), the system achieves spatial diversity and flexible signal coverage without being constrained by external vehicle body adaptations.
2Reliability
If a smart antenna is mounted on the vehicle roof, then signal coverage can be achieved, but the available space is strictly limited and it is visibly mounted which is not always desired
Solution Approach 1:
The antenna system is extracted from the traditional external roof-mounted position and relocated to the interior of the vehicle. This extraction allows the antennas to be hidden within the cabin space, eliminating visible mounting while maintaining signal coverage functionality through strategic internal placement.
Solution Approach 2:
The vehicle interior structures (dashboard, ceiling panels, door panels) serve as intermediaries that house and conceal the antenna elements. These intermediate structures allow the antennas to be positioned optimally for signal coverage while remaining aesthetically pleasing and invisible from the exterior.
3Reliability
If a (smart) antenna is individually adapted to each vehicle body, then optimal signal coverage can be achieved, but the adaptation process is time-consuming and costly
Solution Approach 1:
The antenna elements are designed as universal, vehicle-agnostic components that can be installed in multiple standard positions within any vehicle interior. The modular design with standardized mounting options allows the same antenna components to be used across different vehicle models without requiring custom adaptation for each vehicle body type.
Solution Approach 2:
Instead of adapting the physical antenna structure to each vehicle, the system achieves optimization by changing the positional parameters of the antenna elements. By adjusting the location, orientation, and combination of multiple antenna elements within the vehicle interior, optimal signal coverage is achieved through parameter variation rather than physical adaptation.
4Adaptability or versatility
If multiple antennas are arranged in different directions, then total communication angle is increased, but the system complexity increases
Solution Approach 1:
Multiple antenna elements with different communication angles are merged into a unified antenna system that works together to provide comprehensive coverage. The antennas are coordinated through a common control system that manages signal transmission and reception across all elements, achieving wide-angle coverage while maintaining system coherence.
