Actuating Projection for Sealed Window Protection

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing protective devices for vehicle or building openings, such as insect protection devices, do not allow for the operation of windows or doors without risking the entry of insects, pollen, fine dust, or other contaminants into the vehicle or building.

Innovation Solution

A protective device with a protective textile that includes an opening covered by an actuating projection, allowing a user to operate a window or door without exposing the opening to contaminants, as the actuating projection remains movable and protective over the opening.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the protective fabric is removed or an opening is exposed to allow window or door operation, then the window or door can be operated, but insects and pollen can enter the building or vehicle

Engineering Contradiction:

Improvewindow operationVSAvoidinsect entry

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The actuating projection forms a pocket structure that is nested within the protective fabric. The pocket is created by attaching one edge of the actuating projection all the way around the opening in the protective fabric, forming a nested protective layer that allows hand insertion while maintaining the barrier function.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The actuating projection serves as an intermediary element between the user's hand and the window/door mechanism. It allows the user to reach through the opening in the protective fabric and operate the window or door without directly exposing the opening to the external environment, thus preventing insect and pollen entry.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If the protective device is made fully sealed to prevent contaminant entry, then protection is maximized, but window and door operation becomes impossible

Engineering Contradiction:

Improvecontaminant exclusionVSAvoidwindow operation

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The protective fabric maintains its sealed, protective quality over the entire opening except for the specific location where the actuating projection is attached. The actuating projection creates a localized access point that allows operation while the rest of the protective fabric remains intact and sealed, preserving the protective function in all other areas.

Inventive Principle:

Principle #3Local quality

3Ease of operation

If an opening is created in the protective textile for hand insertion, then window operation is enabled, but the opening exposes the interior to insects and pollen

Engineering Contradiction:

Improvehand insertionVSAvoidpollen entry

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

Inventive Principle:

Principle #7Nested doll (Nesting)
