Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional recreational vehicle window treatment adjustment systems require removing the screen to access and adjust the slider device, which is inefficient.

Innovation Solution

A window treatment adjustment assembly with a longitudinally-extending guide rail, a slider, and a pocket in the screen that allows the handle to extend through and move the slider without removing the screen, utilizing a resilient shroud member to cover the opening when not in use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the screen is kept in place to maintain protection functionality, then the screen can prevent insects and debris from entering, but the slider device becomes inaccessible for adjusting window treatments

Engineering Contradiction:

Improvescreen protection functionalityVSAvoidaccessibility of slider device

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The screen is segmented by creating an opening that separates the screen into two portions, allowing the slider device to be accessed through the opening while the screen remains in place to provide protection. This segmentation enables simultaneous access to the slider and maintenance of screen functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A shroud member is introduced as an intermediary element that selectively covers the opening. The shroud member can be positioned to cover the opening when not in use, maintaining screen protection, and can be moved away to allow access to the slider device for adjustments.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the screen is removed to access the slider device, then the slider becomes accessible for adjustment, but the screen's protective function is lost and additional steps are required

Engineering Contradiction:

Improveaccessibility of slider deviceVSAvoidtime required for adjustment process

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The screen is divided by creating an opening, allowing the slider device to be accessed through the screen opening rather than requiring complete removal of the screen. This eliminates the time-consuming steps of removing and reattaching the screen while maintaining protective coverage.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The shroud member serves as a mediator that can be temporarily moved to allow slider access and then returned to its covering position. This intermediary mechanism enables quick access to the slider without permanently removing the screen, significantly reducing the time required for adjustment operations.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If an opening is created in the screen to access the slider device, then the slider becomes accessible, but the opening may compromise the screen's protective function

Engineering Contradiction:

Improveaccessibility of slider deviceVSAvoidinsect and debris protection

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The screen is segmented with a strategically positioned opening that provides access to the slider device while minimizing impact on protective coverage. The opening is sized and positioned to allow slider access while the majority of the screen remains intact to prevent insects and debris from entering.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The shroud member acts as a movable intermediary that covers the opening when not in use, restoring the screen's protective function. During slider adjustment, the shroud can be moved away to allow access, and then returned to cover the opening, thus maintaining protection against harmful factors during normal operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A window treatment adjustment assembly is provided that includes a slider having a base movable along a portion of the frame. A handle extends from the base. A pocket is formed in the screen and includes: a pocket frame attached to the screen to form an opening through the screen; a shroud member attached to at least a portion of the pocket frame. The handle of the slider extends through the opening of the pocket and past the shroud member. The base of the slider is in communication with a mechanism that moves the window treatment.
