Solution Overview

Problem

Existing radar systems for vehicles lack the ability to efficiently adapt to different intended uses, such as varying mounting locations and alignments, which limits their versatility and effectiveness in performing radar measurements.

Innovation Solution

The radar system employs a basic control scheme that is specified based on the intended use of the system, allowing the basic main beam axis of the transmitting antenna arrangement to be aligned with a radar system reference region for different measurement modes. This adaptation can be achieved through software changes, eliminating the need for hardware modifications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the radar system is designed for a specific mounting location and alignment, then the measurement precision is improved, but the adaptability to different intended uses deteriorates

Engineering Contradiction:
Improveradar measurement precisionVSAvoidadaptability to different mounting locations and alignments
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent applies parameter changes by modifying control scheme parameters (beam steering angles, beamforming weights) to adapt the radar system's main beam axis to different mounting locations and alignments. The control device stores multiple control schemes with different parameter sets, allowing the system to switch between them based on the intended use, thereby maintaining measurement precision across various installations without hardware changes.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements universality by designing a single radar system that can perform multiple functions across different mounting locations and alignments. By incorporating multiple pre-configured control schemes that can be selected based on the intended use, the system achieves multi-functionality and adaptability without requiring separate radar units for each application scenario.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the radar system is adapted to different intended uses through hardware modifications, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:
Improveadaptability to different intended usesVSAvoidhardware complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces mechanical/hardware adaptation methods with an electronic/software-based solution. Instead of physically modifying the radar system's hardware (antenna positions, mounting structures) to adapt to different uses, the system uses a control device that stores and switches between multiple control schemes. This substitution of mechanical adaptation with electronic control reduces device complexity while maintaining adaptability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes operational parameters (beam steering angles, beamforming weights, main beam axis orientations) through software rather than hardware modifications. The control device contains multiple control schemes with different parameter sets that can be selected based on the intended use, allowing the system to adapt to different mounting locations and alignments without increasing hardware complexity.

Inventive Principle:
Principle #35Parameter changes
