Solution Overview

Problem

Conventional ventilating devices with both static pressure and drain orifices increase costs and compromise airtightness, confusing users and affecting performance.

Innovation Solution

A ventilating device with orifices that simultaneously measure static pressure and drain water, positioned in the airflow path where dew accumulates, eliminating the need for additional drain orifices and improving airtightness by using the same orifices for both functions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate static pressure orifice and drain orifice are provided, then both functions are achieved, but device complexity and cost increase

Engineering Contradiction:

Improvefunctional capabilityVSAvoidorifice quantity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent makes the static pressure orifice serve dual functions by enabling it to both measure static pressure and drain accumulated water. This is achieved by strategically positioning the orifice in the airflow path where dew accumulates, allowing the same opening to fulfill both measurement and drainage roles, thereby reducing device complexity and cost.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines the static pressure orifice and drain orifice into a single integrated opening. By positioning the static pressure orifice at a location where water naturally accumulates in the airflow path, the design merges two previously separate functions into one component, simplifying the overall device structure.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If separate static pressure orifice and drain orifice are provided, then both functions are achieved, but manufacturing cost increases

Engineering Contradiction:

Improvefunctional capabilityVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The static pressure orifice is designed to perform multiple functions (pressure measurement and drainage), eliminating the need for a separate drain orifice and reducing manufacturing costs associated with creating and installing additional components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

By merging the drainage function into the existing static pressure orifice, the patent reduces the total number of components that need to be manufactured, assembled, and installed, thereby lowering overall manufacturing costs.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If separate static pressure orifice and drain orifice are provided, then both functions are achieved, but airtightness deteriorates

Engineering Contradiction:

Improvefunctional capabilityVSAvoidairtightness

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent achieves both pressure measurement and drainage functions through a single orifice, reducing the number of potential leakage points in the system. Fewer orifices mean fewer opportunities for airtightness to deteriorate, thereby improving system reliability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Ease of repair

If user opens panel for inspection, then maintenance is enabled, but user gets wet from accumulated water

Engineering Contradiction:

Improvemaintenance accessibilityVSAvoidwater accumulation

Core Design Contradiction:

Ease of repairVSObject-affected harmful factors

Solution Approach 1:

The patent enables preliminary drainage of accumulated water through the static pressure orifice before the user opens the panel for maintenance. By positioning the orifice to drain water that accumulates in the airflow path, the system proactively removes harmful water accumulation, preventing the user from getting wet during inspection.

Inventive Principle:

Principle #10Preliminary action

AI summary

A ventilating device includes a frame forming an outer contour, an airflow path formed by a flowing of air inside the frame, and a plurality of orifices configured to measure a static pressure in a chamber where the airflow path is located, wherein at least one orifice of the plurality of orifices is further configured to drain water out of the frame. In the present disclosure, the orifice for static pressure measurement is provided in the air supply path and/or the air discharge path at a position where the dew is dominantly accumulated, the drainage function and the function of measuring the static pressure may be realized simultaneously, reducing the cost and ensuring air tightness.
