Solution Overview

Problem

Existing devices for maintaining barn floor-covering materials are insufficient in maintaining the condition of the floor, particularly in dairy cattle barns, as they fail to efficiently manage soiled and unssoiled materials effectively, leading to discomfort and health issues for the animals.

Innovation Solution

A device with a controllable pick-up mechanism, adjustable rotation direction and speed of a rotatable tillage device, and a measuring system to determine the parameter values of the floor-covering material, allowing for precise control of material lifting and displacement, separation of soiled and unssoiled materials, and efficient energy use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the pick-up device continuously lifts and processes floor-covering material, then the floor-covering is maintained, but energy is wasted on processing already clean material

Engineering Contradiction:
Improvefloor-covering maintenance qualityVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

A measuring device determines a parameter value (moisture content, temperature, or odor concentration) of the floor-covering material before it is lifted. The pick-up device is controlled based on this parameter value, creating a feedback loop that prevents processing of already clean material and optimizes energy consumption while maintaining floor-covering quality.

Inventive Principle:
Principle #23Feedback

2Productivity

If the rotation speed of the tillage device is increased to lift more material, then productivity improves, but energy consumption increases

Engineering Contradiction:
Improvematerial processing rateVSAvoidrotation energy
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The rotation speed of the tillage device is made dynamically adjustable based on the parameter value determined by the measuring device. When the floor-covering material is clean (parameter value within threshold), the rotation speed is reduced or stopped. When material needs processing (parameter value exceeds threshold), the rotation speed increases to lift and process more material, optimizing both productivity and energy consumption.

Inventive Principle:
Principle #15Dynamics

3Reliability

If the pick-up device lifts all floor-covering material for processing, then clean material is recovered, but processing time for already clean material is wasted

Engineering Contradiction:
Improvefloor-covering cleanlinessVSAvoidprocessing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The measuring device extracts information about the floor-covering material condition (moisture content, temperature, or odor) before lifting. This allows the control device to selectively process only contaminated material by comparing the parameter value against a threshold, extracting only the necessary processing action while skipping clean material to reduce processing time.

Inventive Principle:
Principle #2Taking out (Extraction)

4Ease of operation

If the measuring device is positioned upstream to detect material before lifting, then processing decisions are improved, but the device complexity increases

Engineering Contradiction:
Improveprocessing decision accuracyVSAvoidmeasuring system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The measuring device is designed to measure multiple parameters (moisture content, temperature, odor concentration) using a single integrated system positioned upstream of the pick-up device. This multi-functional approach improves processing decision accuracy by considering multiple indicators of contamination while avoiding the complexity of multiple separate measuring systems.

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