Solution Overview

Problem

Existing silage cutting devices mounted on tractors cannot cut and transport silage simultaneously, leading to inefficient silage removal and uneven cutting across the silo width, as they rely on the tractor for movement and operation.

Innovation Solution

A self-propelled device with roll means and linear guides for autonomous entry into the silo, equipped with a cutting mechanism that can move along the full width and height for even cutting, and a conveyor system for independent silage transport into a separate container, allowing continuous cutting and efficient silage distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the cutting device is mounted on a tractor, then the device can be moved into the silo, but the cutting and transporting operations cannot be performed simultaneously, leading to waiting time

Engineering Contradiction:
Improvesilage cutting efficiencyVSAvoidwaiting time for transport
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The device is divided into functionally independent modules: a cutting unit with milling cutters and a separate conveying unit with a conveyor belt. This segmentation allows the cutting mechanism to operate independently from the transport mechanism, enabling simultaneous cutting and conveying operations without mutual interference or waiting time.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A conveyor belt acts as an intermediary element between the cutting zone and the discharge point. The conveyor continuously transports cut silage away from the cutting area, enabling the cutting operation to proceed without waiting for transport capacity, thus eliminating idle time for both cutting and transport functions.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the device is mounted on a tractor, then it can be positioned in the silo, but the silage cannot be removed evenly across the full width of the silo

Engineering Contradiction:
Improvedevice positioningVSAvoidevenness of silage removal
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The cutting device incorporates movable components including a conveyor belt that can be adjusted in position and a support structure with rollers that allow lateral movement. This dynamic configuration enables the cutting and conveying system to adapt to different positions across the silo width, ensuring uniform silage removal throughout the entire cross-section of the silo.

Inventive Principle:
Principle #15Dynamics

3Reliability

If a shielding plate is used to protect the cutter, then the cutter is protected when not cutting, but the device cannot autonomously advance into the silo without a tractor

Engineering Contradiction:
Improvecutter protectionVSAvoidautonomous movement capability
Core Design Contradiction:
ReliabilityVSExtent of automation

Solution Approach 1:

The device is equipped with its own propulsion system including rollers and a support structure that enables it to autonomously advance into the silo without requiring external traction from a tractor. The shielding plate remains in place during autonomous movement, providing continuous cutter protection while the device independently positions itself within the silo.

Inventive Principle:
Principle #25Self-service
