Solution Overview

Problem

Existing forestry monitoring systems rely heavily on human operators for planning and guiding forestry machines, lacking real-time data collection and guidance during operations, and are unable to effectively manage environmental impact and safety.

Innovation Solution

A forestry monitoring system utilizing an unmanned aerial vehicle (UAV) equipped with an imaging arrangement and computing device to collect and process site information, determining path decisions for forestry machines using AI/ML techniques, and optionally offloading computation to remote servers or on-site machines.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If human operators manually evaluate aerial photography to plan forestry operations, then flexibility and adaptability are maintained, but productivity and real-time monitoring capability are reduced

Engineering Contradiction:
Improveforestry operation efficiencyVSAvoidreal-time monitoring capability
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system enables self-service automation where the forestry monitoring system independently captures aerial imagery, processes it through AI/ML algorithms, and generates path decisions without requiring continuous human intervention. The automated pipeline processes imagery to identify tree locations, assess terrain, and determine optimal machine paths in real-time, allowing the system to serve itself rather than relying on manual human evaluation of aerial photography.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If more imaging sensors are added to the UAV to collect comprehensive forestry site information, then measurement precision and monitoring quality improve, but device complexity and energy consumption increase

Engineering Contradiction:
Improveforestry site information accuracyVSAvoidUAV system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The imaging arrangement is designed with multi-functionality to collect diverse forestry site information using a unified sensor system. The sensors are configured to capture multiple types of data (visual imagery, depth information, thermal data) that serve various monitoring purposes including tree detection, terrain assessment, and path planning, thereby achieving comprehensive measurement precision without proportionally increasing device complexity.

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

Solution Approach 2:

Multiple imaging functions are merged into a single integrated imaging arrangement on the UAV. Rather than deploying separate specialized sensors for each type of measurement, the system combines visual, depth, and thermal imaging capabilities in one unified platform, reducing overall system complexity while maintaining comprehensive monitoring precision through coordinated multi-functional sensors.

Inventive Principle:
Principle #5Merging (Combining)

3Speed

If computation is performed on the UAV itself to enable real-time path decisions, then response speed improves, but the UAV's energy consumption and device complexity increase

Engineering Contradiction:
Improvepath decision response timeVSAvoidUAV energy consumption
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

The computing function is extracted from the UAV and relocated to ground-based computing devices or remote servers. The UAV's imaging arrangement captures and transmits data, while the computationally intensive AI/ML processing for path decision-making is performed externally. This extraction allows real-time response speeds to be maintained through efficient data transmission and processing, while the UAV's energy consumption and device complexity are minimized by eliminating onboard computing hardware.

Inventive Principle:
Principle #2Taking out (Extraction)

4Productivity

If the UAV continuously monitors the forestry site to provide real-time guidance, then productivity and safety improve, but energy consumption increases

Engineering Contradiction:
Improveforestry operation productivityVSAvoidUAV energy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

Instead of continuous monitoring, the UAV employs periodic action by capturing aerial imagery at scheduled intervals and transmitting data for batch processing. The imaging arrangement collects site information at specific time points, allowing the system to maintain productivity through regular updates while significantly reducing energy consumption compared to continuous real-time streaming and processing throughout the entire forestry operation.

Inventive Principle:
Principle #19Periodic action
