Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor mounting systems on vehicles, such as those using LiDAR and cameras, are prone to being obstructed by rain, snow, dust, and other environmental factors, which hinders their performance in real-world object detection and navigation.
Innovation Solution
A mounting base with airflow generating components, including air ducts and fins, is designed to create airflow around the sensors, reducing the likelihood of obstruction by particles and maintaining sensor performance in various conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are mounted on the exterior of a vehicle, then object detection and navigation capabilities are improved, but the sensors become susceptible to obstruction by rain, snow, dust, and other environmental factors
Solution Approach 1:
The patent applies pneumatic principles by using airflow generating components (such as fans or air ducts) to create a controlled airflow field around the sensor. This airflow acts as a protective mechanism that actively prevents particles like rain, snow, and dust from accumulating on the sensor surface, thereby maintaining sensor reliability in harsh environmental conditions
2Reliability
If sensors are protected from environmental factors, then operational reliability is improved, but the mounting system becomes more complex
Solution Approach 1:
The patent merges the airflow generation function directly into the sensor mounting base, creating an integrated assembly where the airflow generating component is positioned to protect the sensor without requiring separate protection mechanisms. This integration reduces overall system complexity while maintaining operational reliability
