Extendable Side Camera Arm for Vehicle View and Aerodynamics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular vision systems lack the ability to provide an enhanced rearward and sideward view while maintaining vehicle aesthetics and aerodynamics, and are prone to damage and water intrusion.
Innovation Solution
The implementation of extendable and retractable side-mounted camera devices that pivot relative to the vehicle body, providing a flush fit when retracted and an extended position for improved viewing, with sealing mechanisms to prevent water intrusion and impact protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the camera device is extended outward from the vehicle body, then the rearward and sideward viewing capability is improved, but the vehicle aesthetics and aerodynamics deteriorate
Solution Approach 1:
The camera device is designed to be movable between extended and retracted positions. When extended, it provides enhanced viewing capability for rearward and sideward views. When retracted, it maintains vehicle aesthetics and aerodynamics by being flush with the body surface. This dynamic positioning resolves the contradiction between viewing capability and vehicle appearance.
Solution Approach 2:
The camera system is segmented into a movable camera device and a fixed body portion, allowing independent positioning. The camera device can be extended only when needed for viewing, while the body portion maintains its streamlined shape, thus resolving the conflict between functional requirement and aesthetic requirement.
2Measurement precision
If the camera device is extended outward from the vehicle body, then the viewing capability is improved, but the vulnerability to damage and water intrusion increases
Solution Approach 1:
The camera device moves between extended and retracted positions. When retracted, it is protected within the vehicle body, reducing vulnerability to damage and water intrusion. When extended, it provides enhanced viewing capability. This dynamic design allows the system to alternate between protection and functionality.
Solution Approach 2:
The camera device is provided with impact protection features and sealing mechanisms before potential damage or water intrusion can occur. The retracted position itself serves as protective cushioning, and additional protective structures are incorporated to prevent damage during operation.
3Shape
If the camera device is retracted flush with the vehicle body, then the vehicle aesthetics and aerodynamics are maintained, but the viewing capability deteriorates
Solution Approach 1:
The camera device is designed to dynamically change position between retracted (flush with body) and extended (outward from body) states. When retracted, it maintains vehicle aesthetics and aerodynamics. When extended, it provides enhanced viewing capability. This resolves the contradiction by allowing the system to adapt its position based on operational requirements.

AI summary
A vehicular camera monitoring system includes an electronic control unit (ECU) at a vehicle and a support arm movably disposed at a side portion of the vehicle, with the support arm having a base end attached at the side portion of the vehicle and a distal end opposite the base end. A camera is disposed at the distal end of the support arm. The support arm is movable between a stowed position and an extended position. A cover element covers an aperture at the side portion at least when the support arm is in the extended position. The camera, when the support arm is in the extended position, captures image data and provides captured image data to the ECU, which processes the provided image data for (i) display of video images derived from provided image data and/or (ii) detection of an object in the field of view of the camera.
