Solution Overview

Problem

Existing ventilation systems are inconvenient to install or replace regulating units, as they require detaching and shortening lines connected to nozzles, and have external cables that increase space requirements and vulnerability.

Innovation Solution

The flow-rate regulator carrier can be installed or replaced by being pushed transversely into a guide within the central housing, with all connections and cables housed internally, allowing for easier handling and reduced space requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If pipe-shaped regulating units are placed onto nozzles on the outside of the central housing with external cables, then the ventilation system can control air flow from different rooms, but the installation and replacement of regulating units becomes inconvenient and space requirements increase

Engineering Contradiction:
Improveair flow control capabilityVSAvoidinstallation convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The carrier housing containing the flow-rate regulator is nested within the central housing of the ventilation system. The carrier can be pushed transversely into the housing through an opening, with all components (regulator, measuring unit, cables) contained within the housing volume. This eliminates the need for external cable management and allows easy installation by simply pushing the carrier into place without detaching lines or adapting connections.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of manufacture

If pipe-shaped regulating units with external cables are used, then the ventilation system can be assembled, but the cables increase space requirements and vulnerability

Engineering Contradiction:
Improvesystem assemblyVSAvoidcable vulnerability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The cables and connections are extracted from the external environment and placed entirely within the protected interior of the central housing. The carrier housing contains all electrical connections between the flow-rate regulator and the control unit, eliminating external cable exposure. This protects cables from mechanical damage, environmental factors, and accidental disconnection while maintaining full system functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If regulating units are installed externally on nozzles, then the ventilation system can be configured for different rooms, but replacement requires detaching and shortening connected lines

Engineering Contradiction:
Improveroom-specific configurationVSAvoidregulating unit replacement
Core Design Contradiction:
Adaptability or versatilityVSEase of repair

Solution Approach 1:

The system is segmented into a modular carrier unit that can be independently installed, removed, and replaced. The carrier housing containing the flow-rate regulator is separated from the main ventilation housing, allowing the carrier to be pushed in and out through an opening without affecting other components. This modular design enables easy replacement of individual room regulators while maintaining connections to the central control system.

Inventive Principle:
Principle #1Segmentation

4Reliability

If the central housing is provided with a cover to protect internal components, then reliability is improved, but access to internal components for installation becomes more difficult

Engineering Contradiction:
Improvecomponent protectionVSAvoidcomponent accessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The carrier housing is designed to be inserted through a transverse opening in the central housing cover, utilizing a different spatial dimension for access. Instead of requiring direct access to the interior space for installation, the carrier can be pushed in from the exterior through a specifically designed opening. This maintains the protective cover while enabling easy installation and replacement of the flow-rate regulator carrier.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

The invention relates to a ventilation system consisting of a central housing (6) having at least one nozzle (5), an active ventilator (7) in the housing and a flow-regulating means. The flow-regulating means comprises a flow-rate regulator (18, 21) for regulating an air flow through the nozzle, at least one measuring system (22, 23) for measuring a property of the air, and a regulating system (9) for controlling the flow-rate regulator on the basis of a property of the air measured by the measuring system. A carrier (10) is connected to a nozzle (5) inside the central housing (6), said carrier (10) comprising at least the flow-rate regulator (18, 21).
