Work Efficiency Estimation for Agricultural Harvesting Progress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crop collection management systems do not consider work efficiency when estimating progress, leading to inadequate assessment of workload completion times.
Innovation Solution
A work management method and system that calculates work efficiency based on operation information from field devices, estimating completion times and outputting signals for progress tracking, while also estimating target efficiencies for given completion times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If work progress is estimated based on collection amount brought in at the collection site, then the estimation method is simple, but work efficiency of the producer is not taken into consideration
Solution Approach 1:
The patent merges two estimation approaches: (1) collection site-based estimation using collection amount data, and (2) field work-based estimation using work efficiency data from work devices. By combining these methods, the system captures both the simplicity of collection monitoring and the accuracy of work efficiency measurement, resolving the contradiction between simplicity and information completeness
Solution Approach 2:
The patent introduces a communication device as an intermediary that collects and transmits work efficiency data from work devices to the estimation system. This intermediary enables the integration of field work data without requiring direct complex interaction between work devices and the estimation system, maintaining system simplicity while gaining work efficiency information
2Measurement precision
If work efficiency calculation is implemented based on operation information from work devices, then work progress estimation accuracy is improved, but system complexity increases
Solution Approach 1:
Work devices automatically generate and transmit their own operation information to the communication device without requiring external intervention. This self-service approach enables accurate work efficiency calculation while minimizing the complexity of data collection, as the system uses existing device capabilities rather than adding external monitoring equipment
Solution Approach 2:
The communication device serves multiple functions: it acts as a data collection point for work efficiency information, a transmission node for sending data to the estimation system, and potentially a storage device for operation information. This multi-functionality reduces the need for separate dedicated components, thereby reducing overall system complexity while maintaining measurement precision

AI summary
[Problem] To assist a user in understanding a progress status. [Solution] A work management method includes calculating work efficiency that represents a workload performed by at least one work device 30 in a unit time on the basis of operation information indicative of work performed by the at least one work device 30 in a field. The work management method also includes estimating an estimated completion time when the work is completed on the basis of the work efficiency and a total workload 550 to be performed by the at least one work device 30. The work management method further includes outputting an estimated completion signal indicative of the estimated completion time that has been estimated.
