Solution Overview

Problem

Existing feed mixers struggle to accurately weigh and add feed supplements due to their design for high weight measurements, resulting in limited precision and increased time and effort for farmers.

Innovation Solution

A feed mixer with a dedicated feed supplement weighing device and conveying system that allows for precise measurement and automatic addition of supplements to the mixing container, offering higher accuracy and reduced manual handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a feed weighing device designed for high weight measurements is used to weigh feed supplements, then the device can measure the total feed weight, but the measurement precision for small feed supplement quantities deteriorates

Engineering Contradiction:
Improvefeed supplement weight measurement precisionVSAvoidweighing device configuration complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The weighing system is segmented into two independent weighing devices: a feed weighing device for the mixing container and a feed supplement weighing device for the additional container. Each device is optimized for its specific measurement range, with the feed supplement weighing device providing high precision for small quantities while the feed weighing device handles large quantities.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control unit acts as an intermediary that receives weight signals from both weighing devices, processes the data, and coordinates the dosing and mixing processes. This intermediary component integrates the two independent weighing systems into a unified control architecture.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If feed supplements are weighed using an external scale before addition, then measurement precision can be improved, but the time and effort required increases

Engineering Contradiction:
Improvefeed supplement weight measurement precisionVSAvoidtime for weighing and adding feed supplement
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The feed supplement weighing device is integrated with the additional container and the feed mixer system. The weighing, dosing, and mixing operations are merged into a single coordinated process controlled by the control unit, eliminating the need for separate external weighing operations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The feed supplement is weighed in advance in the additional container using the feed supplement weighing device before being automatically dosed into the mixing container. This preliminary weighing action allows the system to prepare the exact required amount ready for immediate transfer and mixing.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If a dedicated feed supplement weighing device is added to the feed mixer, then measurement precision for feed supplements improves, but the device complexity increases

Engineering Contradiction:
Improvefeed supplement weight measurement precisionVSAvoidfeed mixer system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The control unit serves multiple functions: it receives weight signals from both weighing devices, controls the dosing of feed supplements, monitors the mixing process, and manages the overall operation of the feed mixer. This multi-functional control unit reduces the need for separate control systems for each component.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A feed mixer has a mixing container (2) for mixing feedstuffs, at least one additional container (8) for holding a feed supplement, and a feed weighing device for weighing the feedstuff filled into the mixing container (2). Furthermore, in addition to the feed weighing device of the mixing container (2), the feed mixer has a feed supplement weighing device (10) for weighing the feed supplement filled into the additional container (8).
