Solution Overview

Problem

Existing crop analysis apparatuses in combine harvesters face reliability and consistency issues due to variable grain supply, especially when the harvester is on a sloped surface, leading to irregular image-taking frequencies.

Innovation Solution

The crop analysis apparatus is designed with a grain entrance located in a plane parallel to the elevator's outer plane on the up-going side, featuring a sloped gutter portion that ensures a constant supply of crops to the analysis area, eliminating the need for a level sensor and maintaining a fresh batch for analysis by positioning the entrance and gutter above the analysis area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the grain entrance is located at the conventional position, then the apparatus structure is simple, but the grain supply becomes unreliable on sloped surfaces

Engineering Contradiction:
Improvegrain supply reliabilityVSAvoidapparatus structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The grain entrance is repositioned from a conventional side-mounted location to a position in the up-going path plane of the elevator, utilizing a different spatial dimension. This dimensional change allows gravity to naturally feed grain into the analysis chamber regardless of harvester slope, eliminating the need for complex mechanical feed mechanisms while ensuring reliable grain supply.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If the grain entrance is positioned to ensure constant supply, then image-taking frequency increases, but the apparatus requires more space above the analysis area

Engineering Contradiction:
Improveimage-taking frequencyVSAvoidhousing height
Core Design Contradiction:
ProductivityVSLength of stationary object

Solution Approach 1:

The grain entrance and sloped gutter are positioned above the analysis chamber to pre-feed and accumulate grain in the analysis area before imaging occurs. This preliminary positioning ensures that a complete batch of grain is always ready for analysis, enabling continuous high-frequency imaging without requiring excessive housing height.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If the harvester operates on sloped surfaces, then field operational capability is maintained, but grain supply to the analyser becomes irregular

Engineering Contradiction:
Improvefield operational capabilityVSAvoidgrain supply consistency
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

By positioning the grain entrance in the up-going path plane and using a sloped gutter configuration, the system creates a gravity-driven feed mechanism that maintains equipotential grain flow conditions. This ensures consistent grain supply to the analysis chamber regardless of the harvester's orientation or slope, allowing field operation on various terrains without compromising supply stability.

Inventive Principle:
Principle #12Equipotentiality
