Solution Overview

Problem

Remotely operated machines like multicopters face difficulty in writing or digitally printing precise identification information on structures due to proximity issues, making it challenging to identify abnormal parts.

Innovation Solution

Spray a liquid material onto a target object to form an irregular spray pattern, image the pattern, and associate it with object information for identification, using a liquid material ejection device and imaging means mounted on a moving object.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a remotely operated machine is used to write or digitally print identification information on a structure, then precise identification information can be added, but it is difficult to get close to the target object for printing or drawing

Engineering Contradiction:

Improveidentification information precisionVSAvoidaccess to target object

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The patent replaces the mechanical system of writing or digitally printing identification information with a spray painting system. The liquid material ejection device sprays paint to form identification patterns on the target object, eliminating the need for precise mechanical contact or digital printing mechanisms that require close proximity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses a liquid material ejection device that sprays paint through pneumatic or hydraulic mechanisms. This allows identification information to be applied remotely by spraying,无需 close contact with the target object, while still achieving precise and clear identification patterns.

Inventive Principle:

Principle #29Pneumatics and hydraulics

2Ease of operation

If spray painting is used to form identification information, then close proximity is not required, but the identification information must be unique and recognizable

Engineering Contradiction:

Improveremote operation capabilityVSAvoididentification uniqueness

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent utilizes the inherent asymmetry and randomness in spray patterns created by the liquid material ejection device. Each spray pattern is unique due to variations in spray dynamics, target surface characteristics, and environmental factors, ensuring that every identification mark is distinct and recognizable.

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The patent employs color variations in the sprayed liquid material to enhance identification uniqueness. Different colors or color patterns can be used to distinguish between different target objects or different identification instances, making the spray patterns easily recognizable and unique.

Inventive Principle:

Principle #32Color changes

3Ease of manufacture

If liquid material is sprayed to form identification patterns, then simple identification is achieved, but the liquid material must be ejected precisely to the target region

Engineering Contradiction:

Improveidentification method simplicityVSAvoidspray positioning accuracy

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent incorporates imaging means to capture images of the target object and the spray patterns. This visual feedback system allows for real-time monitoring and adjustment of spray positioning, ensuring that liquid material is ejected precisely to the intended target regions while maintaining simple identification methodology.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent uses imaging means to pre-identify and mark target regions before spray application. By capturing images and determining precise target locations in advance, the system ensures accurate spray positioning without requiring complex real-time control during the spraying process itself.

Inventive Principle:

Principle #10Preliminary action
