Vehicle Box Panel Stroke Limiting for ADAS Sensor Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The collision of vehicle box panels with ADAS sensors can damage these sensors, violating regulations and incurring economic loss, especially in vehicles equipped with Advanced Driver Assistance Systems (ADAS).
Innovation Solution
A containment system for vehicle box panels that limits their stroke to prevent contact with the chassis, using a pin and guide mechanism with recesses to control angular positions and includes a tensioning system to maintain contact, ensuring the panel does not collide with the chassis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the panel is allowed to move freely for easy loading/unloading, then the ease of operation is improved, but the panel may collide with the chassis and damage ADAS sensors
Solution Approach 1:
The containment system is pre-configured with a pin and guide mechanism that defines a predetermined stroke path for the panel. This preliminary structural arrangement ensures that the panel automatically follows a safe trajectory during movement, preventing collision with the chassis and ADAS sensors before the collision can occur.
Solution Approach 2:
The guide mechanism acts as an intermediary element between the panel and the chassis. It mediates the panel's movement by constraining it to a predetermined stroke, thereby protecting the ADAS sensors from direct contact while still allowing the panel to move for loading and unloading operations.
2Reliability
If the panel stroke is limited to prevent sensor damage, then the reliability is improved, but the versatility of loading/unloading operations is reduced
Solution Approach 1:
The containment system incorporates a tensioning mechanism with a movable element that can be positioned at different locations along the panel's stroke path. This dynamic adjustability allows the system to adapt to different loading/unloading scenarios while maintaining reliable protection of the ADAS sensors through the predetermined stroke constraint.
3Object-affected harmful factors
If a containment system is added to limit panel stroke, then the sensor protection is improved, but the device complexity increases
Solution Approach 1:
The containment system is segmented into distinct functional components: a guide mechanism with a pin that defines the predetermined stroke, and a separate tensioning mechanism with a movable element. This segmentation allows for modular installation and maintenance while achieving sensor protection through the coordinated action of these simpler individual components.
