Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional laboratory analysis methods are used for spore detection, then measurement precision can be achieved, but loss of time and productivity are significantly increased

Engineering Contradiction:
Improvespore detection accuracyVSAvoiddetection time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces conventional mechanical laboratory analysis methods with an automated optical detection system. The device uses a light source and detector to automatically identify and count spores, eliminating the need for manual microscopic examination while maintaining measurement precision and significantly reducing detection time.

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

Solution Approach 2:

The detection device performs self-analysis by automatically capturing images of spores, processing them through image analysis algorithms, and generating detection results without requiring continuous human intervention. The system autonomously completes the entire detection workflow from sample acquisition to result generation.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If conventional laboratory analysis methods are used for spore detection, then measurement precision can be achieved, but device complexity and manufacturing costs increase

Engineering Contradiction:
Improvespore detection accuracyVSAvoiddetection system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The detection device is designed as a multi-functional integrated system that combines sample collection, optical detection, image processing, and data analysis capabilities in a single unit. This universal design allows the device to perform multiple functions using a unified technical approach, reducing overall system complexity compared to separate specialized equipment.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent employs image processing techniques that analyze specific parameters of spore structures (such as size, shape, and optical properties) to achieve accurate identification. By focusing measurement on key distinguishing parameters rather than requiring complete morphological analysis, the system achieves high precision with simpler equipment.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If fungicides are applied extensively to protect crops from spores, then crop protection reliability is improved, but harmful factors to health and environment increase

Engineering Contradiction:
Improvecrop protection reliabilityVSAvoidhealth and environmental risks
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The detection device provides real-time feedback on spore presence and concentration in the environment. This information feeds back to the crop protection system, enabling dynamic adjustment of fungicide application timing and dosage. Fungicides are applied only when spore detection thresholds are exceeded, rather than through routine extensive application.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary detection of spores before they reach concentrations that threaten crop health. By detecting spores early in their presence, the system enables preventive action at optimal moments, allowing for minimal effective fungicide application rather than reactive extensive treatment after infection begins.

Inventive Principle:
Principle #10Preliminary action
