Autonomous Vehicle Sensor Placement Below the Roof Peak
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomously movable vehicles face challenges in acquiring external world information over a wider angle area due to limitations in the placement of external world information acquisition devices, which can lead to damage when encountering obstacles, disrupting autonomous movement.
Innovation Solution
The vehicle is designed with external world information acquisition devices positioned on the upper surface of the outer shell member, specifically below the uppermost portion, to prevent damage from obstacles and maintain a unified visual appearance without increasing the vehicle's height or width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the external world information acquisition device is mounted on the upper surface of the outer shell member to acquire external world information in a wider angle area, then the acquisition area of external world information is improved, but the device is more likely to come into contact with obstacles and suffer damage
Solution Approach 1:
The patent transitions from mounting the acquisition device on the side surface (2D placement) to the upper surface (3D placement), utilizing the vertical dimension to expand the acquisition area while managing the associated risks through careful positioning below the uppermost portion
2Area of moving object
If the external world information acquisition device is provided on the upper surface of the outer shell member, then the acquisition area of external world information is improved, but the visual appearance unity of the moving body is deteriorated
Solution Approach 1:
The patent applies local quality by positioning the acquisition device at a specific location on the upper surface (below the uppermost portion) rather than uniformly across the surface, creating a localized solution that balances functional requirements with aesthetic considerations

AI summary
A moving body including a first external world information acquisition device is autonomously movable based on first external world information acquired by the first external world information acquisition device. An outer shell member of the moving body includes an upper surface facing upward of the moving body. The first external world information acquisition device is provided on the upper surface. The first external world information acquisition device is arranged below an uppermost portion of the upper surface in an upper-lower direction of the moving body.
