Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing window coverings for non-rectangular windows, such as arch-shaped windows, face challenges in providing adjustable light and dark effects due to their unique shapes, which differ from the standard rectangular designs.

Innovation Solution

A window covering system comprising a frame with a base and arch segments, featuring moveable panel portions and a control element within a hollow arch frame, allowing for manual or remote-controlled operation to adjust light permeability by aligning light and dark strips on two panels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If standard rectangular window covering designs are used, then manufacturing and operation are simple, but they cannot accommodate non-rectangular window shapes

Engineering Contradiction:

Improveadaptability to non-rectangular window shapesVSAvoidcomplexity of frame structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The window covering frame is divided into multiple segments including a base frame segment and at least one non-rectangular arch frame segment. This segmentation allows the frame to be customized for different window shapes while maintaining modular construction benefits.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If fixed panel positioning is used, then structure is simple, but light and dark effects cannot be adjusted

Engineering Contradiction:

Improveadjustability of light and dark effectsVSAvoidcomplexity of control mechanism

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The window covering includes a moveable panel portion that can be repositioned relative to a fixed panel portion. This dynamic configuration allows users to adjust the alignment of light and dark strips to control light penetration and create desired light or dark effects.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

A control element is provided that connects to the moveable panel portion and extends through the hollow arch frame portion. This intermediary control mechanism facilitates easy adjustment of the panel position without requiring complex mechanical systems.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If control elements are placed outside the frame, then operation is accessible, but aesthetic appearance is compromised

Engineering Contradiction:

Improveaccessibility of control elementVSAvoidaesthetic appearance of arch frame

Core Design Contradiction:

Ease of operationVSShape

Solution Approach 1:

The control element is contained within the hollow arch frame portion, which is designed to accommodate the control element internally. This nesting arrangement maintains the aesthetic appearance of the arch frame while providing accessible control through an opening in the base frame segment.

Inventive Principle:

Principle #7Nested doll (Nesting)
