Solution Overview

Problem

Existing beet crop harvesting machines cause wounds on the roots, leading to rotting and significant losses due to inadequate foliage cutting and cleaning processes, which are not effectively addressed by current methods such as using foils or rot inhibitors.

Innovation Solution

A beet crop harvesting machine equipped with a defoliating cutting device, an uprooting device, a rotary sieve for cleaning, and a sealing applicator device that applies a sealing liquid, such as limewater, to form a mechanical barrier on the cut locations and during transport to protect the roots from damage and contamination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the root crop is cut and conveyed on the harvesting machine, then the harvesting process is completed, but the root develops wounds that lead to rotting

Engineering Contradiction:
Improveharvesting process completionVSAvoidroot crop preservation
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The sealing liquid is applied to the root crop at the cutting location before the root crop is conveyed and stored. This preliminary sealing action prevents subsequent rotting by creating a protective barrier at the vulnerable wound site before the root crop undergoes further handling and storage processes.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

A sealing liquid is introduced as an intermediary substance between the cutting device and the root crop storage. This sealing liquid fills the gap by providing a protective layer that prevents harmful interactions (rotting) between the exposed root crop tissue and the environment during conveyance and storage.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If foils or rot inhibitors are used to protect the root crop heap, then rotting is reduced, but the cost and complexity increase

Engineering Contradiction:
Improveroot crop preservationVSAvoidprotection method complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The protection function is extracted from the storage phase (foils covering the heap) and moved to the processing phase (sealing liquid application during conveyance). This extraction simplifies the storage system by eliminating the need for complex foil covering mechanisms while maintaining preservation effectiveness through the sealing liquid applied earlier in the process.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If the root crop is cleaned in the path from uprooting to reservoir, then cleaning is provided, but the cleaning efficiency is insufficient

Engineering Contradiction:
Improvecleaning provisionVSAvoidcleaning efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The mechanical cleaning system is replaced or supplemented by applying a sealing liquid that provides protective functionality. This substitution improves efficiency by combining cleaning and protection functions in a more effective manner, addressing the insufficiency of purely mechanical cleaning approaches.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
