Position Restriction Device for Aerial Cargo Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flight body systems face challenges in achieving precise positioning accuracy of loads during delivery, particularly in windy conditions and when operating in confined spaces, due to environmental factors and satellite signal variability.
Innovation Solution
A position restriction device for suspension members, comprising a restricting member and a guide part, which restricts the movement of the suspension member to improve positional accuracy by guiding it to a fixed position, allowing for secure detachment of loads without the flight body landing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a load is suspended from a flight body using a cable for delivery, then the flight body can operate without landing, but the positioning accuracy of the load deteriorates due to environmental winds and flight body movement causing the load to sway and shift position
Solution Approach 1:
The patent introduces a guide structure as an intermediary element between the flight body and the load. This guide structure constrains the movement of the suspension cable, preventing excessive swaying and position shifts caused by wind and flight body movement. The guide structure acts as a mediator that maintains positioning accuracy while still allowing the flight body to operate without landing.
2Extent of automation
If GNSS is used to control the position of the flight body, then the flight body can be controlled remotely, but the position accuracy varies depending on satellite supplementation status
Solution Approach 1:
The patent implements a guide structure that provides mechanical positioning assistance in advance, cushioning against the variability of GNSS positioning. By providing a physical guide that constrains cable movement, the system compensates for position accuracy variations before they affect the load delivery precision, ensuring consistent performance regardless of satellite supplementation status.
3Adaptability or versatility
If loads are delivered to narrow land or compact ports, then home delivery service coverage is improved, but the positioning accuracy requirements increase due to limited space for load placement
Solution Approach 1:
The guide structure serves as a mediator that enables precise load placement in confined spaces. By constraining the suspension cable within the guide structure, the system achieves the high positioning precision required for narrow land and compact port deliveries, thereby expanding service coverage to areas that would otherwise be inaccessible.
