Solution Overview

Problem

Existing flying objects used for agricultural harvesting may perform work at unintended locations, leading to inefficiencies and potential damage due to high-speed collisions with collection vehicles.

Innovation Solution

A work system comprising a flying object with a work section, a collection vehicle, and control units to manage work based on collection vehicle position, including range setting and speed reduction mechanisms to ensure precise and controlled delivery of work-related items.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If the flying object performs harvesting work automatically based on captured images, then the labor required for harvesting work is reduced, but work may be performed at unintended locations

Engineering Contradiction:
Improveautomated harvestingVSAvoidwork location accuracy
Core Design Contradiction:
Extent of automationVSReliability

Solution Approach 1:

The system uses real-time position information from both the flying object and collection vehicle to create feedback loops. The work control unit continuously monitors the relative position and adjusts the work execution accordingly, ensuring the flying object operates only within the intended work range around the collection vehicle.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The work control unit acts as an intermediary between the automated harvesting system and the collection vehicle position data. It processes position information from both vehicles and mediates the work execution, enabling the automated system to adapt to the collection vehicle's location and prevent unintended work at incorrect positions.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If the flying object delivers work-related items to the collection vehicle, then work efficiency is improved, but collision damage may occur due to high-speed falling

Engineering Contradiction:
Improvework efficiencyVSAvoidcollision damage
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system prepares for potential collision damage beforehand by using the buffer section in the collection vehicle. This cushioning mechanism is预先 installed to absorb impact energy when work-related items fall from the flying object, preventing damage to both the items and the vehicle.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The system converts the potentially harmful high-speed falling of work-related items into a beneficial delivery mechanism. By controlling the release timing and using the buffer section to manage impact, the system transforms what could be damaging collisions into efficient item transfer, maintaining productivity while preventing damage.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

3Ease of operation

If the flying object operates independently without position control, then operational simplicity is maintained, but work may be performed at incorrect positions

Engineering Contradiction:
Improveoperational simplicityVSAvoidposition accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The flying object performs self-positioning by autonomously acquiring its own position information and comparing it with the collection vehicle's position. The work control unit enables the system to self-regulate its operation based on real-time position data, maintaining ease of operation while achieving precise position control without complex external intervention.

Inventive Principle:
Principle #25Self-service
