Solution Overview

Problem

Current poultry breeding methods are inconvenient for sampling feces in densely populated areas, as workers need to enter breeding areas, causing obstruction and difficulty in collecting samples.

Innovation Solution

A long-distance sampling device using an unmanned aerial vehicle (UAV) equipped with a sampling unit, including a cylindrical sampling tube with spiral blades and automatic telescopic feet, which can collect and store fecal samples without human intervention, allowing the UAV to operate above the breeding area and avoid animal obstruction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If workers manually sample feces in breeding areas, then sampling can be conducted directly at the source, but workers are obstructed by high animal density and must drive away animals, causing inconvenience and safety issues

Engineering Contradiction:
Improvesampling convenienceVSAvoidanimal obstruction
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

An unmanned aerial vehicle (UAV) is introduced as an intermediary device to perform sampling operations in breeding areas. The UAV flies above the animals, avoiding direct contact and obstruction, while still accessing fecal samples through its sampling mechanism. This mediator resolves the conflict between needing direct sample access and avoiding animal interference.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The sampling operation transitions from a ground-level horizontal movement through dense animal populations to an aerial three-dimensional approach. The UAV operates in the vertical dimension above the breeding area, eliminating the need to navigate through animal obstructions on the ground plane.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If workers enter breeding areas to sample feces, then samples can be collected from within the breeding areas, but the sampling personnel need to drive away animals which causes inconvenience and increases safety risks

Engineering Contradiction:
Improvesampling accuracyVSAvoidoperator convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The UAV serves as an intermediary that maintains reliable sampling capability while eliminating the need for human operators to physically enter breeding areas. The sampling unit on the UAV collects fecal samples with the same reliability as manual sampling, but without exposing workers to animal obstructions and safety risks.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The manual mechanical sampling process performed by workers is replaced with an automated mechanical sampling system on the UAV. The sampling unit with its rotating shaft and blades automatically collects samples without human intervention, improving operator convenience while maintaining sampling reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If manual sampling is used in densely populated breeding areas, then fecal samples can be collected, but the process is time-consuming and inefficient due to the need to navigate through animals

Engineering Contradiction:
Improvesampling efficiencyVSAvoidsampling time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

By operating in the aerial dimension, the UAV bypasses the time-consuming navigation through dense animal populations on the ground. The UAV can directly position itself over target areas and perform sampling rapidly, significantly improving sampling efficiency and reducing the time required for each sampling operation.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The automated sampling mechanism on the UAV replaces the slow manual sampling process. The motor-driven rotating shaft with blades automatically penetrates and collects fecal samples, eliminating the time workers would spend manually navigating through animals and collecting samples, thereby increasing productivity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
