Window Shade Pocket Lighting With Non-Plenum Cable Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Window shade systems face challenges in determining pocket locations that comply with varying fire codes and require different types of cabling, leading to increased costs and complexity due to the need for plenum vs. non-plenum cables, especially when the pockets are considered part of the ceiling or plenum spaces.
Innovation Solution
A window shade pocket system that integrates a light source and cabling within a modular, lightweight, and cost-effective design, allowing for the use of non-plenum cabling by positioning the pocket outside the plenum space and incorporating brackets that retain cabling and electrical components, while supporting various ceiling systems and attachments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plenum cable is used to comply with fire codes in plenum spaces, then fire safety is improved, but cost increases
Solution Approach 1:
The patent extracts the wiring system from the plenum space by routing cables through the pocket structure that is positioned outside the plenum area. This allows the use of less expensive non-plenum rated cables while maintaining fire safety compliance, as the cables no longer pass through the air circulation space above the ceiling.
Solution Approach 2:
The pocket structure serves as an intermediary element that bridges the window shade system and the mounting structure. By positioning the pocket and its associated wiring outside the plenum space, it mediates between the need for ceiling mounting and the requirement to avoid plenum-rated expensive cables.
2Adaptability or versatility
If pocket size is increased to accommodate different shade sizes and features, then adaptability is improved, but weight and cost increase
Solution Approach 1:
The pocket structure is segmented into modular components that can be configured in different sizes and arrangements. This allows the system to accommodate various shade sizes by assembling appropriate pocket modules without requiring a single large, heavy pocket structure for all applications.
Solution Approach 2:
The pocket design incorporates universal mounting features and standardized dimensions that allow the same basic pocket structure to accommodate multiple shade sizes and configurations. This multi-functionality reduces the need for multiple specialized pocket types, thereby reducing overall system weight and complexity.

AI summary
The window shade pocket system may comprise a pocket having a first wall and a second wall; a window shade having a first side and a second side, wherein the window shade is mounted within the pocket and is configured to at least partially extend over a window outside of the pocket; and a first bracket removably affixed to at least one of a closure extending from the first wall, the first wall or the second wall, wherein the first bracket retains a light source, and wherein the light source is configured to illuminate an exterior area outside of the window. The light source may illuminate the exterior area outside of the window, in response to at least one of an opening of the window, an object coming through the window, a person coming through the window, an object passing by the window or a person passing by the window.
