Solution Overview

Problem

Conventional vehicular radars have limitations in accurately detecting stationary objects due to twisted installation angles, leading to reduced detection range and increased risk of traffic accidents, maintenance costs, and anxiety for drivers.

Innovation Solution

An installation angle distinction apparatus that inputs relative distance, velocity, and elevation angle values to estimate the vertical height and installation angle of stationary objects, determining abnormal angles and adjusting the radar's position to maintain optimal alignment, while also providing navigation to nearby maintenance centers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the radar is installed adjacent to the bumper, then the installation is simple and compact, but the installation angle becomes twisted due to external impacts, reducing detection accuracy

Engineering Contradiction:

Improveinstallation simplicityVSAvoiddetection accuracy

Core Design Contradiction:

Ease of manufactureVSMeasurement precision

Solution Approach 1:

The system continuously monitors the radar's installation angle using multiple detectors and provides feedback to a control unit. When the angle deviates from the optimal range, the system generates alerts and can automatically adjust the radar position, resolving the contradiction by maintaining precision despite the simple initial installation

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The radar system performs self-diagnosis and self-adjustment through the installation angle distinction apparatus. The detectors and control unit work autonomously to monitor and correct the installation angle, eliminating the need for constant manual intervention while maintaining detection accuracy

Inventive Principle:

Principle #25Self-service

2Device complexity

If the vertical installation angle is twisted, then the radar structure remains simple, but the detection range is shortened and high-position objects cannot be detected

Engineering Contradiction:

Improveradar structure complexityVSAvoiddetection range

Core Design Contradiction:

Device complexityVSArea of stationary object

Solution Approach 1:

The system uses detectors to continuously monitor the vertical installation angle and provides feedback to the control unit. When the angle deviates from the optimal range, the system alerts the driver and can automatically adjust the radar, maintaining full detection range without increasing structural complexity

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The radar system transitions from a static installation to a dynamic one where the installation angle can be automatically adjusted. The adjustable mechanism allows the radar to adapt its angle in real-time, expanding the effective detection range while keeping the base structure simple

Inventive Principle:

Principle #15Dynamics

3Device complexity

If no installation angle monitoring is implemented, then the system remains simple, but the reliability of the detector decreases and maintenance costs increase

Engineering Contradiction:

Improvesystem complexityVSAvoiddetector reliability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The installation angle distinction apparatus provides continuous monitoring and feedback on the radar's installation angle. This feedback mechanism enables early detection of angle deviations, allowing for timely adjustments that maintain detector reliability and prevent costly repairs

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary monitoring and adjustment of the installation angle before significant deviations occur. By detecting and correcting angle issues early, the system maintains detector reliability and prevents problems that would lead to increased maintenance costs

Inventive Principle:

Principle #10Preliminary action
