Solution Overview

Problem

The existing loading process of fodder mixer wagons is complex and error-prone, as the driver must manually control all operating parameters, leading to increased workload and potential errors during the loading process.

Innovation Solution

A method for controlling the loading process of a fodder mixer wagon using a loading control unit that automatically controls various loading components based on the type and quantity of feed components, reducing driver workload and preventing errors by optimizing the operation of components such as the pick-up tool, loading belt, and mixing tool.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the driver manually controls all operating parameters of loading components, then the driver retains full control of the feed mixer wagon, but the loading process becomes extremely complex and prone to errors

Engineering Contradiction:

Improveloading process accuracyVSAvoidloading process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The loading control unit automatically determines and controls operating parameters of loading components based on feed component information, enabling the system to self-regulate the loading process without requiring the driver to manually manage each parameter, thus reducing complexity while maintaining reliability

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The loading control unit acts as an intermediary between the driver's activation command and the loading components, automatically determining optimal operating parameters and controlling the components accordingly, which simplifies the driver's task while ensuring reliable operation

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If the driver controls loading components simultaneously while driving, then the loading process can be completed, but the driver's workload increases and errors occur

Engineering Contradiction:

Improveloading speedVSAvoiddriver workload

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The control unit extracts the complex task of determining and adjusting operating parameters from the driver's responsibilities, automatically managing loading component parameters while the driver focuses on driving and initiating the loading process, thereby reducing workload without compromising productivity

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The control unit preliminarily determines optimal operating parameters for loading components based on stored information about feed components before the actual loading begins, so that when loading starts, the components are already configured correctly, reducing the driver's real-time workload while maintaining efficient loading speed

Inventive Principle:

Principle #10Preliminary action

3Reliability

If mechanical loading components are activated automatically based on feed component information, then operating errors are prevented and driver workload is reduced, but the driver may lose control of the loading process

Engineering Contradiction:

Improveloading accuracyVSAvoiddriver control

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system implements partial automation where the control unit automatically determines operating parameters and controls loading components, but the driver retains the ultimate authority to activate and deactivate the loading process and individual components, providing excessive control capability that ensures driver authority is never completely lost

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system dynamically adjusts the level of automation based on driver input - the driver can activate the loading control unit to enable automatic parameter control, or deactivate it to retain full manual control, making the control system flexible and adaptive to the driver's preferences and situational needs

Inventive Principle:

Principle #15Dynamics

4Productivity

If loading components operate at high speed to complete loading quickly, then productivity increases, but energy consumption and contamination increase

Engineering Contradiction:

Improveloading speedVSAvoidenergy consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The control unit dynamically adjusts the operating speed of loading components based on the specific feed component being loaded and the current loading state, optimizing speed to achieve the necessary productivity while minimizing energy consumption and contamination risks associated with excessively high speeds

Inventive Principle:

Principle #15Dynamics
