Delivery Vehicle Door Orientation Control Against Wind Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The door of an unmanned vehicle can unintentionally close due to wind influence, preventing the recipient from receiving the article.
Innovation Solution
The unmanned vehicle is equipped with a wind identification unit and a door closing suppression unit that adjusts the vehicle's direction to prevent the door from closing due to wind, ensuring the door remains open for article retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the door is opened for article retrieval, then the recipient can access the article, but the door may unintentionally close due to wind influence
Solution Approach 1:
The control unit performs preliminary action by identifying wind direction before the door closing issue occurs, and proactively adjusts the vehicle orientation or activates suppression mechanisms to prevent the door from closing due to wind, thereby maintaining accessibility while ensuring door stability
Solution Approach 2:
The control unit implements feedback by continuously monitoring wind direction and door state, and dynamically adjusting the vehicle orientation or door suppression control based on real-time wind conditions, ensuring the door remains open for article retrieval while protecting against unintended closure
2Reliability
If the vehicle orientation is adjusted to suppress door closing, then door stability is improved, but the recipient access convenience may be affected
Solution Approach 1:
The control unit applies dynamics by making the vehicle orientation adjustable and adaptable based on wind conditions, allowing the system to dynamically find an optimal orientation that both stabilizes the door against wind and maintains convenient access for the recipient, rather than using a fixed orientation

AI summary
The unmanned vehicle for delivering an article, includes a housing portion for housing the article, the housing portion having an opening portion for receiving the article and being provided with an openable and closable door that is closeable on the opening portion. Then, the unmanned vehicle identifies a direction of wind blown onto the unmanned vehicle; and suppresses, on the basis of the identified direction of the wind, closing of the door opened when the unmanned vehicle is stopped, due to an influence of the wind.
