Solution Overview

Problem

The installation of heating, ventilation, and air conditioning systems requires multiple trades, increasing costs and time due to the complexity of hydraulic and electronic connections, which complicates the arrangement of piping elements and valves.

Innovation Solution

A control box with a hydraulic regulation compartment that allows for easy fixation and adjustment of various piping elements and accessories before installation, featuring orthogonal support surfaces and clamping mechanisms for secure positioning, and a separate electronic compartment for simplified electrical connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple trades are involved on site for installing hydraulic and electronic systems, then the system can be properly installed with correct hydraulic arrangement and electronic control, but the installation time and costs increase

Engineering Contradiction:
Improveproper installation qualityVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent combines hydraulic control components and electronic control components into a single integrated control box. The hydraulic manifold with valves and piping elements is housed together with the electronic control unit, power supply, and connection terminals in one unified structure. This merging allows a single installer to complete both hydraulic and electronic connections at the same location without coordinating multiple trades, thereby reducing installation time while maintaining proper installation quality through integrated design.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The control box serves multiple functions simultaneously: it houses hydraulic valves for flow control, contains piping elements for fluid distribution, provides electronic control circuitry for automation, and offers mounting interfaces for various configurations. This multi-functionality consolidates what would traditionally require separate installations by different specialists into a single universal device that can be installed by one person.

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

3Ease of manufacture

If hydraulic components are fixed directly to wall, ceiling or floor, then the hydraulic system can be installed, but the arrangement freedom is limited and requires multiple trades

Engineering Contradiction:
Improvehydraulic system installationVSAvoidarrangement freedom
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent segments the hydraulic system into modular components mounted on a manifold within the control box. Instead of fixing individual pipes and valves directly to structural elements, the system uses a centralized manifold that can be positioned flexibly. The manifold is divided into sections with standardized connection points, allowing various piping configurations while maintaining installation simplicity through modular assembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control box acts as an intermediary between the hydraulic components and the building structure. Rather than directly fixing pipes to walls or ceilings, all hydraulic elements are mounted on the manifold inside the control box, which then connects to the building's hydraulic network. This intermediary structure provides arrangement freedom while simplifying the installation process.

Inventive Principle:
Principle #24Intermediary (Mediator)
