Solution Overview

Problem

Existing feed vehicles experience high energy consumption and inaccuracies in delivering precise amounts of feed due to compressing large amounts of feed, leading to inefficiencies in energy use and delivery accuracy.

Innovation Solution

A feed vehicle equipped with a dual-pump mechanism, including a screw pump and a linear actuator-driven pump, which minimizes feed compression to the mouthpiece, allowing for accurate and rapid delivery of predetermined feed portions directly to the top wall of cages.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If a single pump is used to compress large amounts of feed from the container through the tubing to the outlet opening, then feed delivery is achieved, but energy consumption increases and delivery accuracy decreases

Engineering Contradiction:
Improveenergy consumptionVSAvoiddelivery accuracy
Core Design Contradiction:
Use of energy by moving objectVSMeasurement precision

Solution Approach 1:

The feed delivery system is segmented into two separate pump functions: a first pump that transfers feed from the container to the tubing, and a second pump that delivers feed from the mouthpiece outlet opening. This segmentation allows each pump to handle only the necessary portion of feed, minimizing compression and improving both energy efficiency and delivery accuracy

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The tubing acts as an intermediary element between the first pump and the second pump, allowing feed to be transferred without requiring a single pump to compress the entire volume. The dual-pump arrangement with tubing as mediator reduces the compression burden on each pump individually

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If a single pump compresses large amounts of feed, then feed is delivered through the system, but the compression process reduces delivery speed and accuracy

Engineering Contradiction:
Improvedelivery speedVSAvoidportion size accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

By dividing the pump function into two separate pumps, the system can operate more efficiently. The first pump handles bulk transfer while the second pump precisely controls the final delivery, enabling faster overall delivery without compromising portion size accuracy

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system changes the operational parameters by using two pumps with different functions rather than one pump. The second pump is specifically configured to deliver precise portions with minimal compression, changing the delivery parameters to achieve both speed and accuracy

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If feed is compressed between the pump and outlet opening, then feed is pushed through the tubing, but the compression increases energy consumption

Engineering Contradiction:
Improvefeed delivery functionVSAvoidenergy consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The compression function is segmented between two pumps, with each pump performing minimal compression on its respective portion of feed. This reduces the total energy required compared to a single pump compressing the entire feed volume from container to outlet

Inventive Principle:
Principle #1Segmentation
