Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If optical sensors (rotating cameras) are used for forest fire detection, then detection capability is provided, but false detections occur and effectiveness is reduced at night

Engineering Contradiction:
Improvedetection reliabilityVSAvoidfalse detections and night ineffectiveness
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent combines multiple detection sensors (optical sensors, gas sensors, temperature sensors, and infrared sensors) into an integrated forest fire detection system. This multi-sensor fusion approach allows the system to cross-validate detections and distinguish actual fire signals from false alarms caused by dust clouds or other environmental factors, thereby improving reliability while maintaining effectiveness during nighttime conditions.

Inventive Principle:
Principle #5Merging (Combining)

2Area of stationary object

If satellite monitoring is used for forest fire detection, then large area coverage is achieved, but resolution is insufficient for early detection and costs are high

Engineering Contradiction:
Improvemonitoring coverage areaVSAvoidfire detection resolution
Core Design Contradiction:
Area of stationary objectVSMeasurement precision

Solution Approach 1:

The patent segments the monitoring system into multiple ground-based detection stations distributed across the forest area. Each station uses local sensors to provide high-resolution detection within its coverage zone, while collectively the network covers large areas. This segmentation approach achieves both broad coverage and precise early detection without the high costs and resolution limitations of satellite monitoring.

Inventive Principle:
Principle #1Segmentation

3Reliability

If low orbit satellites are used for monitoring, then detection capability is improved, but satellites are not geostationary requiring orbital time and creating gaps in monitoring

Engineering Contradiction:
Improvedetection capabilityVSAvoidmonitoring gaps during orbital completion
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements a network of autonomous ground-based detection stations that continuously monitor forest areas without requiring orbital passages or external control. Each station operates independently and continuously, eliminating the monitoring gaps inherent in orbital satellite systems while maintaining reliable detection capability through local environmental sensing.

Inventive Principle:
Principle #25Self-service

4Measurement precision

If close-meshed satellite monitoring is implemented, then detection precision is improved, but large number of satellites are required increasing launch costs and carbon dioxide emissions

Engineering Contradiction:
Improvedetection precisionVSAvoidlaunch costs and carbon dioxide emissions
Core Design Contradiction:
Measurement precisionVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the mechanical system of launching multiple satellites with ground-based electronic sensing systems. By deploying detection stations throughout the forest area, the system achieves close-meshed monitoring precision without the high costs and environmental harm associated with launching numerous satellites, thereby substituting a mechanically intensive space-based system with a distributed terrestrial sensor network.

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