Retractable Laser Radar Fender Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laser radars for intelligent driving face challenges due to their large size, limited visual field angle, high cost, and vulnerability to collision and maintenance issues, particularly when mounted on vehicle bumpers, which affects styling and increases collision risk.
Innovation Solution
A laser radar integrated device with a retractable design, featuring a cover plate, lifting structure, pop-up structure, and integrated cleaning system, allowing the laser radar to be hidden within the vehicle body when not in use, reducing exposure to damage and enhancing maintenance accessibility, while also reducing the number of radars needed for 360-degree coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the laser radar is mounted on the vehicle bumper, then the installation is simple and the visual field coverage is good, but the collision risk increases and the styling is affected
Solution Approach 1:
The laser radar is designed with a retractable mechanism that allows it to dynamically change its position between extended (working) and retracted (storage) states. This dynamic design enables the radar to be mounted on the bumper for easy installation while reducing collision risk by retracting into the vehicle body when not in use, thus resolving the contradiction between installation simplicity and collision risk
Solution Approach 2:
The laser radar is nested within the vehicle body structure, specifically retracting into a cavity in the front fender. This nesting approach allows the radar to be mounted on the bumper for easy installation while protecting it from collisions by storing it inside the vehicle body, thus resolving the contradiction between installation simplicity and collision risk
2Ease of manufacture
If the laser radar is mounted on the vehicle bumper, then the installation is simple, but the styling is affected and the technological sense is reduced
Solution Approach 1:
The retractable design allows the laser radar to be dynamically hidden within the vehicle body, creating a clean, integrated appearance that enhances styling. When not in use, the radar retracts into the fender cavity, eliminating visual clutter and maintaining the vehicle's aesthetic lines, thus resolving the contradiction between installation simplicity and styling appearance
Solution Approach 2:
By nesting the laser radar within the vehicle body structure, the design achieves a sleek, integrated appearance that enhances styling. The radar is concealed within the fender cavity, creating a seamless look that maintains the vehicle's aesthetic integrity while allowing for simple bumper mounting, thus resolving the contradiction between installation simplicity and styling appearance
3Adaptability or versatility
If 4-5 laser radars are arranged to achieve 360-degree coverage, then the visual field coverage is complete, but the cost increases significantly
Solution Approach 1:
The laser radar is designed with adjustable mounting angles and rotatable capabilities, allowing a single radar to dynamically adjust its detection direction. This enables one radar to cover multiple angles and positions, replacing the need for 4-5 fixed radars and thus resolving the contradiction between visual field coverage and number of radars
Solution Approach 2:
The laser radar is designed with multi-functional capabilities, including adjustable mounting positions and rotatable detection directions, allowing it to perform multiple detection functions that would otherwise require multiple separate radars. This universality enables a single radar to achieve 360-degree coverage, resolving the contradiction between visual field coverage and number of radars
4Ease of operation
If the laser radar is exposed on the vehicle bumper, then the accessibility for cleaning is good, but the scratching risk from sand and stone increases
Solution Approach 1:
The retractable design allows the laser radar to dynamically move between exposed (cleaning accessible) and retracted (protected) states. When retracted into the vehicle body, the radar is protected from sand and stone scratching while maintaining cleaning accessibility through the integrated cleaning mechanism, thus resolving the contradiction between cleaning accessibility and scratching risk
Solution Approach 2:
The integrated cleaning mechanism automatically cleans the laser radar lens without requiring manual intervention. The cleaning system includes nozzles that spray cleaning fluid onto the lens and wipers that wipe it clean, allowing the radar to self-maintain even when retracted, thus resolving the contradiction between cleaning accessibility and scratching risk
