Solution Overview

Problem

Existing mixing devices for vegetable products and cattle feed are inefficient due to time-consuming filling of the mixing container, which slows down the mixing process, and increasing the container volume leads to higher power requirements for drive means, undoing the energetic advantages of fermentation processes and causing feed quality deterioration.

Innovation Solution

A mixing device with a buffer container having a movable buffer bottom and vertical buffer wall, allowing quick filling of the mixing container while reducing the need for large volume containers and maintaining controlled power usage, enabling unmanned operation and customizable cattle feed compositions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If the volume of the mixing container is increased to enable unmanned loading for a prolonged period, then the operational duration is improved, but the required power of the drive means increases substantially

Engineering Contradiction:
Improveunmanned operation durationVSAvoidpower of drive means
Core Design Contradiction:
Duration of action of moving objectVSPower

Solution Approach 1:

The system is divided into two separate containers: a buffer container for storing material and a mixing container for active mixing. This segmentation allows the mixing container to remain smaller and require less power while the buffer container handles the bulk storage and feeding functions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A buffer container acts as an intermediary between material storage and the mixing container. The buffer container feeds material to the mixing container through a movable buffer bottom, enabling continuous operation without requiring the mixing container to be oversized.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Duration of action of moving object

If the volume of the mixing container is increased to enable prolonged unmanned operation, then the operational duration is improved, but the cost price increases due to more expensive drive means

Engineering Contradiction:
Improveunmanned operation durationVSAvoidcost price
Core Design Contradiction:
Duration of action of moving objectVSEase of manufacture

Solution Approach 1:

By segmenting the system into buffer and mixing containers, the mixing container can be smaller and less expensive to manufacture, while the buffer container handles the bulk of the material storage requirements for prolonged operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The buffer container serves as an intermediary that enables prolonged operation without requiring the mixing container to be oversized, thereby avoiding the need for expensive high-power drive means.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If the mixing container is filled from a truck with a moving floor, then the loading process is simplified, but the filling time increases and mixing efficiency decreases

Engineering Contradiction:
Improveloading process simplicityVSAvoidmixing efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

Material is pre-loaded into the buffer container before the mixing process begins. The buffer container can be filled in advance and then quickly emptied into the mixing container through the movable buffer bottom, reducing the time the mixing process is interrupted.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The buffer container acts as an intermediary that receives material from the truck and quickly transfers it to the mixing container. This intermediate step allows for faster filling compared to direct loading into the mixing container, thereby improving mixing efficiency.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Productivity

If the mixing container is filled quickly by opening the buffer bottom, then the filling time is reduced and mixing efficiency is improved, but the buffer container requires additional drive means

Engineering Contradiction:
Improvemixing efficiencyVSAvoidadditional drive means
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The buffer bottom is designed to be self-actuating through a simple lifting mechanism that uses the weight of the material itself. When the buffer bottom is lifted, the material gravity-fed into the mixing container without requiring complex drive systems, thus achieving fast filling with minimal additional complexity.

Inventive Principle:
Principle #25Self-service
