Combine Auto-Reaping Recovery Through Abnormality Backtracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combine harvester technologies do not effectively address abnormalities that occur during automatic reaping operations, leading to potential equipment damage and reduced efficiency.
Innovation Solution
A combine harvester equipped with a detecting portion to identify abnormalities and a control portion that interrupts the automatic reaping work, causing the machine to travel backward by a predetermined distance to create space for resolving the issue, and then resumes operation when the abnormality is cleared.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic reaping work continues without interruption when abnormality is detected, then productivity is maintained, but equipment damage may occur and reliability deteriorates
Solution Approach 1:
The control portion performs preliminary action by interrupting the automatic reaping work before equipment damage can occur. When the detecting portion identifies an abnormality, the control portion immediately stops the reaping operation and triggers backward travel, preventing further deterioration of equipment condition while maintaining productivity through automated recovery.
2Ease of repair
If the combine harvester stops and travels backward when abnormality is detected, then ease of repair is improved, but loss of time increases
Solution Approach 1:
The combine harvester performs self-service by automatically detecting abnormalities, interrupting work, traveling backward to create safety space, and resuming operation without operator intervention. This automated self-diagnosis and self-adjustment system improves ease of repair by providing clear abnormality signals and standardized recovery procedures while minimizing time loss through elimination of manual inspection and decision-making steps.
3Object-affected harmful factors
If the combine harvester travels backward by predetermined distance when abnormality is detected, then safety is improved, but productivity decreases
Solution Approach 1:
The control portion applies partial action by traveling backward only by a predetermined distance (not full stop and not excessive distance). This partial movement creates sufficient safety space for resolving abnormalities while minimizing productivity loss. The system uses the minimum necessary action to achieve the safety objective, then immediately resumes work to maintain overall efficiency.

AI summary
This combine is provided with: a body part including a mowing part for mowing grain culms; a travel part for supporting the body part and traveling; a detection part for detecting an abnormality in the body part; and a control part which executes automatic mowing work for causing the mowing part to mow grain culms while causing the travel part to autonomously travel and carries out control such that, when the detection part detects an abnormality during the automatic mowing work, the automatic mowing work is interrupted and subsequently the travel part is made to travel backward by a first predetermined distance.
