Solution Overview

Problem

Existing pressure reducers for animal water troughs are cumbersome to adjust manually and require additional energy sources like compressed air, making them inefficient and time-consuming, especially in larger stables with multiple units.

Innovation Solution

A pressure reducer that uses the energy from the liquid supply to automatically adjust the pressure, incorporating a force-measuring mechanism and hydraulic spring element, allowing precise control of the pressure reduction without external energy sources, and featuring solenoid valves for independent control of inlet and outlet channels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If pressure reducers are manually adjusted, then the pressure can be changed, but it is very time-consuming and requires entering the barn

Engineering Contradiction:
ImprovePressure adjustment operationVSAvoidTime for pressure adjustment
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The pressure reducer uses the liquid pressure itself to automatically adjust the regulating device. The liquid in the water supply acts on the diaphragm, which is connected to the regulating device, enabling automatic pressure adjustment without manual intervention or external energy sources.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical adjustment with an automatic hydraulic control system. The force measuring device detects pressure changes and automatically actuates the regulating device through hydraulic forces, eliminating the need for manual mechanical adjustment.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Extent of automation

If pneumatic adjustment is used to eliminate manual adjustment disadvantages, then adjustment is automated, but it requires compressed air supply and complex network of compressed air lines

Engineering Contradiction:
ImprovePressure adjustment automationVSAvoidCompressed air network
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The patent uses hydraulic principles instead of pneumatic systems. The liquid pressure from the water supply directly acts on the diaphragm and regulating device, eliminating the need for separate compressed air lines and equipment while achieving automatic adjustment.

Inventive Principle:
Principle #29Pneumatics and hydraulics

Solution Approach 2:

The liquid serving as the working fluid performs multiple functions: it is both the substance being pressure-reduced and the medium that provides the energy for automatic adjustment of the regulating device, eliminating the need for separate control systems.

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

3Measurement precision

If pressure reducers are manually adjusted precisely, then the desired reduced liquid pressure can be achieved, but it requires entering the barn and is time-consuming

Engineering Contradiction:
ImprovePressure measurement precisionVSAvoidPressure adjustment operation
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The force measuring device continuously monitors the force on the diaphragm and provides feedback to the control system. Based on this feedback, the regulating device automatically adjusts the pressure to maintain the desired setpoint, achieving precise control without manual intervention.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces manual mechanical adjustment with an automatic electronic control system that uses force measurements and electronic actuators to precisely control the pressure, eliminating the need for manual operation while maintaining high precision.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Adaptability or versatility

If several pressure reducers are installed in larger barns, then each drinking line can be supplied, but the adjustment effort increases further

Engineering Contradiction:
ImproveNumber of drinking lines suppliedVSAvoidTotal adjustment time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

Each pressure reducer automatically adjusts itself using its own liquid pressure, eliminating the need for manual adjustment of each unit. This self-service capability scales efficiently to multiple pressure reducers without increasing operational effort.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent makes each pressure reducer an independent, self-contained unit with automatic adjustment capability. This segmentation allows each unit to operate autonomously, so adding more units to supply additional drinking lines does not increase the adjustment effort for existing units.

Inventive Principle:
Principle #1Segmentation

AI summary

Animal drinking troughs have pressure reducers (15) for reducing the relatively high pressure of the liquid supply to a low liquid pressure for supplying the animal drinking troughs. It is desired for various reasons to change the reduced pressure. This takes place by way of adjustment of the pressure reducers (15). It is known to perform an adjustment of this type by way of compressed air. This requires a separate compressed air source and a corresponding line system. The invention provides adjusting the pressure reducers (15) hydraulically by way of the relatively high pressure of the liquid of the liquid supply. As a result, the energy which is required to adjust the pressure reducers (15) supplies the liquid pressure of the liquid supply. As a result, the pressure reducers (15) according to the invention operate autonomously. A separate energy source for adjusting the pressure reducers (15) is not required.
