Solution Overview

Problem

Existing ventilation valves are susceptible to undesirable influence during maintenance and cleaning, are difficult to remove for maintenance, and lack compact design, leading to aesthetic and functional issues.

Innovation Solution

A ventilation valve with a main body, base, and airflow controller where the airflow controller's position is adjustable via a manually controllable mechanism, and a cover that prevents external access during normal use, allowing for secure and aesthetic adjustment and maintenance without disrupting airflow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the control means is accessible from the exterior side for manual adjustment, then ease of operation is improved, but reliability deteriorates due to undesirable influence during maintenance and cleaning

Engineering Contradiction:
Improvemanual adjustabilityVSAvoidflow setting stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The ventilation valve is divided into multiple detachable components: a main body, a base with airflow controller, and a cover. The base can be detached from the main body for maintenance while the cover remains in place to protect the airflow controller, enabling separate access for adjustment and maintenance purposes

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cover acts as an intermediary element that provides protected access to the airflow controller. During normal operation, the cover prevents direct access to maintain reliability. During maintenance, the cover can be removed to allow access to the base and airflow controller without exposing the entire valve to disruption

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of repair

If the ventilation valve is designed with exposed adjustment mechanism for ease of maintenance, then ease of repair is improved, but aesthetic appearance deteriorates

Engineering Contradiction:
Improvemaintenance accessibilityVSAvoidaesthetic appearance
Core Design Contradiction:
Ease of repairVSShape

Solution Approach 1:

The valve is segmented into a cover, base, and main body that can be independently removed and reattached. This allows the cover to remain in place during normal use to maintain aesthetic appearance, while the base can be detached for maintenance without requiring removal of the entire valve

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The design transitions from a static, fully exposed adjustment mechanism to a dynamic system where the cover and base can be selectively removed and reattached. This enables the valve to switch between an aesthetic closed state during normal operation and an open state during maintenance

Inventive Principle:
Principle #15Dynamics

3Reliability

If the ventilation valve components are permanently fixed for stability, then reliability is improved, but ease of repair deteriorates due to difficulty in removal for maintenance

Engineering Contradiction:
Improvecomponent stabilityVSAvoidmaintenance removability
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The connection between components transitions from permanent to dynamic. The base is detachably connected to the main body via a connection element that provides stable operation during use but allows easy removal for maintenance. The cover is similarly detachably connected to the base, enabling flexible access while maintaining stability during normal operation

Inventive Principle:
Principle #15Dynamics

AI summary

The current invention relate to a ventilation valve, comprising a main body with passage that extends through with means for attaching the main body to a ventilation opening of structure; a base with means for attaching to the base to the main body at a distance to the main body such that an airflow passage extends between them; and an airflow controller to vary the airflow through the airflow passage. The ventilation valve also comprises a cover to prevent access to the exterior side. The cover is detachably connected to the base so that the relative position between the airflow controller and the base is adjusted while the base is attached to the main body. The base is detachably connected to the main body, so that the base and airflow controller is removed from the main body while they are held in place in the relative position between the airflow controller and the base.
