Solution Overview

Problem

Existing systems with vehicles connected by bendable connection elements, such as wires, face issues with increased energy consumption and side drift due to pulling forces, which are not effectively mitigated.

Innovation Solution

A supply system featuring a floating unit with a clamping unit that can switch between fixed and released states, utilizing a gas volume for lift and adjustable gas volume through fluid control, and a platform with aligned connection points for energy and fluid transfer, reducing the pulling force by compensating with a lifting effect.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the aerial vehicle flies farther from the agricultural vehicle, then the free length of the wire increases, but the pulling force in the wire increases

Engineering Contradiction:
Improvefree length of the wireVSAvoidpulling force in the wire
Core Design Contradiction:
Length of moving objectVSForce

Solution Approach 1:

The patent introduces a floating unit filled with gas (helium or hydrogen) that generates buoyant force to counteract the pulling force in the wire. The floating unit acts as a counterweight that offsets the tension caused by the wire's weight and the aerial vehicle's distance from the agricultural vehicle, thereby reducing the net pulling force on the aerial vehicle.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

2Power

If the pulling force acts on the aerial vehicle, then the wire can supply energy and data, but the aerial vehicle experiences side drift requiring active compensation

Engineering Contradiction:
Improveenergy supply capabilityVSAvoidposition stability of the aerial vehicle
Core Design Contradiction:
PowerVSStability of the object's composition

Solution Approach 1:

The floating unit generates upward buoyant force that counteracts the downward pulling force from the wire, thereby reducing the horizontal component of the pulling force that causes side drift. This allows the wire to continue supplying energy and data while minimizing the stabilizing effort required from the aerial vehicle's propulsion system.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

3Reliability

If the clamping unit is in the fixed state, then the floating unit attaches to the bendable connection element, but the system complexity increases

Engineering Contradiction:
Improveattachment reliabilityVSAvoidclamping unit complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The clamping unit utilizes the buoyant force from the gas-filled envelope to automatically clamp onto the bendable connection element. When the floating unit is deployed, the upward buoyant force engages the clamping mechanism without requiring external actuation, thereby achieving reliable attachment while simplifying the control system.

Inventive Principle:
Principle #25Self-service

4Force

If the gas volume in the envelope is increased, then the lifting effect increases, but the volume of the floating unit increases

Engineering Contradiction:
Improvelifting effectVSAvoidvolume of the floating unit
Core Design Contradiction:
ForceVSVolume of moving object

Solution Approach 1:

The patent employs a gas-filled envelope where the gas volume can be adjusted to optimize the lifting effect. By controlling the amount of gas (helium or hydrogen) in the envelope, the system can vary the buoyant force to match the required lifting capability for different operating conditions, thereby achieving maximum lifting efficiency with minimal volume.

Inventive Principle:
Principle #35Parameter changes
