Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a technology that can appropriately control the traveling of vehicles capable of autonomous or remote-controlled driving, especially when they are on a conveyor that moves.
Innovation Solution
A device and method that determine whether a vehicle is on a conveyor, acquire the conveyor's velocity, and decide a target vehicle velocity based on the conveyor's velocity to ensure appropriate control of the vehicle's travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle travels on a conveyor without considering the conveyor velocity, then the vehicle can move autonomously or by remote control, but the vehicle velocity control becomes inaccurate and the traveling control is inappropriate
Solution Approach 1:
The system performs preliminary detection of conveyor presence and velocity measurement before finalizing the vehicle velocity decision. The determination unit detects whether the vehicle is on a conveyor in advance, and the conveyance velocity acquisition unit measures the conveyor velocity beforehand, allowing the decision unit to calculate the appropriate target vehicle velocity in advance, ensuring accurate control from the start of conveyor interaction
Solution Approach 2:
The system continuously monitors the actual vehicle velocity and compares it with the target velocity, then adjusts the velocity decision based on this feedback. When the vehicle is detected to be on a conveyor, the system uses the conveyor velocity as feedback to dynamically adjust the target vehicle velocity, ensuring the vehicle maintains appropriate speed relative to the moving conveyor surface
2Adaptability or versatility
If the system always uses the same target velocity regardless of conveyor conditions, then the control system is simple, but the vehicle cannot adapt to different conveyor velocities and traveling control becomes inappropriate
Solution Approach 1:
The system dynamically adjusts the target vehicle velocity based on real-time detection of conveyor conditions. When the determination unit detects the vehicle is on a conveyor, the decision unit calculates a new target velocity by combining the original target velocity with the measured conveyor velocity, allowing the vehicle to adapt its speed to match the moving conveyor surface
Solution Approach 2:
The system changes the velocity parameter based on conveyor detection. The decision unit modifies the target vehicle velocity parameter by adding or subtracting the conveyor velocity from the original target velocity, depending on the conveyor's direction of movement, enabling the vehicle to adapt to different conveyor conditions through parameter adjustment
