Solution Overview

Problem

Current cob collection devices fail to reliably remove attached husks and leaves from cobs, leading to increased volume and reduced value of collected cobs, and have limited adaptability for travel over public thoroughfares and infrastructure.

Innovation Solution

A cob collection device with an adjustable conveyor system that includes husking rolls to mechanically detach husks from cobs and an inclined conveyor for distributing cobs within a compact container, allowing for efficient cob storage and travel under bridges and utility wires.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a conveyor system is used to collect cobs, then cob collection efficiency is improved, but the system cannot reliably remove attached husks and leaves from cobs

Engineering Contradiction:
Improvecob collection efficiencyVSAvoidhusk removal capability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent extracts the husk removal function from the basic conveyor system by adding a separate husk removal mechanism with rotating husk removal elements that actively strip husks and leaves from cobs as they pass through the conveyor, thereby reliably removing contaminants while maintaining collection efficiency

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges the cob collection conveyor with a husk removal mechanism into an integrated system where cobs are conveyed and simultaneously de-husked within the same device, resolving the contradiction by combining both functions in one reliable system

Inventive Principle:
Principle #5Merging (Combining)

2Quantity of substance

If collected cobs contain attached husks and stover, then collection volume is increased, but storage capacity and value are reduced

Engineering Contradiction:
Improvecollection volumeVSAvoidstorage capacity
Core Design Contradiction:
Quantity of substanceVSVolume of stationary object

Solution Approach 1:

The patent extracts husks and stover from the collected cobs through the husk removal mechanism, removing unwanted material that would otherwise occupy valuable storage space, thereby increasing the effective storage capacity for actual cob material

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent discards husks and stover from the cob collection stream through the husk removal mechanism, separating valuable cobs from low-value contaminants, which maximizes storage capacity and economic value of the collected material

Inventive Principle:
Principle #34Discarding and recovering

3Ease of operation

If the conveyor system is extended to distribute cobs, then cob distribution is improved, but the system cannot travel under bridges and utility wires

Engineering Contradiction:
Improvecob distribution capabilityVSAvoidtravel adaptability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent makes the conveyor system dynamic and adjustable, allowing it to be reconfigured or collapsed to a compact state for traveling under bridges and utility wires, while maintaining full distribution capability when deployed in the field

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent segments the conveyor system into adjustable sections that can be reconfigured for different operational modes, enabling both effective cob distribution during harvesting and compact storage for navigating infrastructure limitations

Inventive Principle:
Principle #1Segmentation

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The device effectively separates husks from cobs, maximizing storage capacity and adaptability, ensuring efficient cob collection and transportation while maintaining soil nutrient levels by returning residual stover to the field.
