Solution Overview

Problem

Existing shade systems for roller blinds face issues with light leaks, inability to adjust guide channels for different fabric depths, and the need for separate channels for blackout and zippered shades, leading to inefficiencies and uniformity problems.

Innovation Solution

A guide channel system with tension mechanisms, such as bent spring wire or molded plastic, that can be inserted into a base channel with adjustable protrusions, allowing for secure retention and depth adjustment, enabling a single shade system to fit various window sizes and switch between blackout and zippered applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a standard zipper guide channel is inserted into a secondary channel and retained with clips, then the zipper guide channel is secured in place, but the system requires separate dedicated side channels for zipper and blackout applications and cannot adjust to different fabric depths

Engineering Contradiction:

Improveretention of guide channelVSAvoidadjustability to different fabric depths and shade types

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The guide channel incorporates a spring mechanism that allows dynamic adjustment of the guide channel's position within the side channel. The spring enables the guide channel to move forward and backward to accommodate different fabric depths while maintaining secure retention through engagement with protrusions at different positions along the side channel.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The guide channel design with adjustable spring mechanism allows a single guide channel to serve multiple functions - it can accommodate both zipper shades and blackout shades by adjusting its position, eliminating the need for separate dedicated side channels for different shade types.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Stability of the object's composition

If guide channel and base channel are specifically designed to work together, then the assembly is structurally integrated, but it is not possible to switch from blackout shade to zippered shade without switching out the whole base channel

Engineering Contradiction:

Improvestructural integrationVSAvoidswitchability between shade types

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The system is divided into separate functional components: a fixed base channel providing structural support, and a movable guide channel with spring mechanism that can be independently adjusted. This segmentation allows the guide channel to be repositioned or removed without affecting the base channel, enabling switching between different shade types.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The guide channel is designed with dynamic movement capability through the spring mechanism, allowing it to be adjusted to different positions within the base channel. This dynamic design enables the same base channel to work with different shade types by simply repositioning the guide channel rather than replacing the entire assembly.

Inventive Principle:

Principle #15Dynamics

3Ease of manufacture

If the guide channel is fixed at a specific depth, then the installation is simple, but certain size shades cannot fit and there is a lack of uniformity in shade width

Engineering Contradiction:

Improvesimplicity of installationVSAvoidcompatibility with different shade sizes

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The spring mechanism provides dynamic depth adjustment capability, allowing the guide channel to be positioned at different depths within the base channel. This enables accommodation of various shade sizes while maintaining uniform appearance through proper positioning, all while keeping the installation process relatively simple.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system allows changing the positional parameter of the guide channel within the base channel to accommodate different shade sizes. By adjusting the depth position of the guide channel, the system adapts to various fabric depths and maintains uniform shade width appearance across different window sizes.

Inventive Principle:

Principle #35Parameter changes

AI summary

A shade channel system and method of use to provide interchangeability of use with a zippered shade and a regular or blackout shade, together with improved efficiency of installation. A guide channel accepts a shade and is configured with a tensioning mechanism to allow the guide channel to be retained at varying depths within a base channel. The system is suitable for providing polished, uniform looks throughout a room and allowing for use of standard-sized shades by allowing the guide channel to be placed at an adjustable depth within a base channel.
