Solution Overview

Problem

Agricultural planters operating autonomously lack the ability to detect and clear debris from gauge wheels, disc openers, trash wheels, and seed tubes, leading to planting inefficiencies and potential damage, as human oversight is absent to manually address clogs.

Innovation Solution

The implementation of sensors such as hall effect sensors, infrared sensors, cameras, vibration sensors, microphones, and accelerometers to detect clogs, combined with motor and spring mechanisms for clearing debris, ensures autonomous detection and remediation of clogs in rotating elements and seed tubes.

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system enables autonomous self-detection and self-clearing of clogs through sensors that monitor component status and actuators that automatically remove debris, allowing the planter to maintain itself without human intervention and thus preserving both productivity and reliability

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Sensors continuously monitor the operational status of gauge wheels, disc openers, trash wheels, and seed tubes, providing real-time feedback to the control system that triggers automated clearing actions when clogs are detected, ensuring reliable operation during autonomous planting

Inventive Principle:

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

Manual mechanical monitoring by human operators is replaced with automated sensor systems that detect clogs through electrical or optical signals, and automated actuators that clear debris mechanically, maintaining detection reliability while eliminating the need for constant human supervision and thus improving productivity

Inventive Principle:

3Reliability

If automated detection systems are added, then reliability improves, but device complexity increases

Engineering Contradiction:
