Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional window treatments with cords can tangle and pose hazards, particularly for children, while also limiting flexibility in adjusting the window covering's length without the need for cords.

Innovation Solution

A cordless window covering system featuring removable securement mechanisms that can be positioned along straps on both sides of the panel, allowing for adjustable lengths without the use of cords, by coupling and decoupling straps at various points to maintain desired positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If cords are used to enable window treatments to move between closed and open positions, then the window treatment can be operated, but the cords may tangle and pose hazards to children

Engineering Contradiction:

Improveoperation of window treatmentVSAvoidtangling hazard to children

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent removes cords entirely from the window treatment system, extracting the harmful element while preserving the operational function through alternative mechanisms (weights, counterweights, or spring systems) that enable the window treatment to move between closed and open positions without any cord components

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces intermediary components such as weights, counterweights, or spring mechanisms that mediate the movement of the window treatment, replacing the direct cord-pull operation with an indirect mechanical system that achieves the same functional result without the tangling hazard

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If cords are used to operate window treatments, then the window treatment can be moved between positions, but the length adjustment is limited and requires cords

Engineering Contradiction:

Improvelength adjustment capabilityVSAvoidcord system requirement

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent employs dynamic adjustment mechanisms where weights or counterweights can be repositioned along the window treatment to different heights, enabling flexible length adjustment without cords. The system transitions from a fixed cord-based structure to a dynamic, reconfigurable mechanism that adapts to various length requirements

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If removable securement mechanisms are positioned at various locations along straps, then the window covering can be drawn at multiple different levels, but the device complexity increases

Engineering Contradiction:

Improveadjustable drawing levelsVSAvoidsecurement mechanism structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the window treatment into segmented components with multiple straps and securement mechanisms positioned at various locations. This segmentation allows the window covering to be drawn at multiple different levels by engaging different strap-securement combinations, providing versatility through modular architecture

Inventive Principle:

Principle #1Segmentation

AI summary

Disclosed herein is a cordless window covering that has one or more removable securement mechanisms that are positionable at various locations along one or more straps that are coupled to a first side of the window covering. Different portions of each of the one or more straps are coupled to the window covering at a number of different positions. This enables the one or more removable securement mechanisms to be removably coupled to each of the different positions.
