Delivery Vehicle Control for Transport Acceleration Displacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing delivery systems, sudden acceleration or deceleration of transportation vehicles can cause unintended displacement of delivery vehicles and manipulators, leading to collisions and potential damage or failure.
Innovation Solution
A delivery system that acquires information on the transportation vehicle's acceleration and predicts the resulting displacement, controlling the delivery vehicle's or manipulator's operation to reduce this displacement, using mechanisms such as adjusting the center of gravity, braking, or active wheel movement to prevent collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the delivery vehicle is carried in the transportation vehicle, then delivery efficiency is improved, but the delivery vehicle may collide against the inner wall due to sudden acceleration or deceleration
Solution Approach 1:
The control unit predicts the displacement of the delivery vehicle based on acceleration information from the transportation vehicle before the collision occurs, and issues control instructions in advance to adjust the driving force or position of the delivery vehicle, preventing the collision before it happens
Solution Approach 2:
The system continuously monitors acceleration information from the transportation vehicle and uses this feedback to predict and control the delivery vehicle's position, creating a closed-loop control system that responds to changing conditions in real-time
2Adaptability or versatility
If the manipulator is provided in the transportation vehicle, then article handling capability is improved, but the manipulator may collide against the inner wall due to sudden acceleration or deceleration
Solution Approach 1:
The control unit predicts the displacement of the manipulator based on acceleration information from the transportation vehicle before the collision occurs, and issues control instructions in advance to adjust the position of the manipulator, preventing the collision before it happens
Solution Approach 2:
The system continuously monitors acceleration information from the transportation vehicle and uses this feedback to predict and control the manipulator's position, creating a closed-loop control system that responds to changing conditions in real-time
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively prevents problems like tumbling or collision of delivery vehicles and manipulators due to sudden vehicle acceleration or deceleration, ensuring safe and reliable delivery operations.
Implementation Method 1
when the transportation vehicle suddenly accelerates or decelerates (when the acceleration of the transportation vehicle increases), a force is exerted on the delivery vehicle carried in the transportation vehicle, so that an unintended displacement (an unintended movement) may occur in the delivery vehicle

AI summary
A delivery system includes an autonomously-moving-type delivery vehicle configured to deliver an article to a delivery destination thereof, and a transportation vehicle configured to carry and transport the delivery vehicle. A control unit configured to control an operation of the delivery vehicle acquires information about an acceleration of the transportation vehicle from the transportation vehicle, and controls the operation of the delivery vehicle based on the information about the acceleration so that a displacement that is predicted to occur in the delivery vehicle due to the acceleration of the transportation vehicle is reduced.
