Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional window shades are cumbersome to install and remove due to their fixed head rail design, which adds weight and complicates repair and cleaning operations.
Innovation Solution
A window shade system with a shade assembly that includes a roller and shade structure connected via a pivotally locked coupler, allowing for easy detachment and attachment to a support surface using a connector and bracket system, and featuring a roller lock for secure rotation control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional fixed head rail design is used, then the window shade provides stable support, but it adds weight and makes installation and removal cumbersome
Solution Approach 1:
The head rail is divided into multiple segments that can be detached from each other. Each segment can be independently handled during installation and removal, reducing the weight burden on any single component while maintaining overall structural stability when assembled.
Solution Approach 2:
The head rail transitions from a fixed, static structure to a dynamic, reconfigurable structure. The segments can be connected and disconnected as needed, allowing the system to adapt between a stable assembled state for use and a disassembled state for easy installation and removal.
2Stability of the object's composition
If a conventional fixed head rail design is used, then the window shade maintains structural integrity, but it complicates repair and cleaning operations
Solution Approach 1:
By segmenting the head rail into separate sections, the patent enables easy access to different parts of the structure for cleaning and repair operations. Individual segments can be removed or accessed without disassembling the entire structure, maintaining structural integrity when assembled while improving maintenance accessibility.
3Reliability
If a conventional fixed head rail design is used, then the window shade provides continuous support, but it makes deinstallation difficult
Solution Approach 1:
The head rail segments incorporate quick-connect mechanisms that provide continuous, reliable support when assembled but allow for rapid disconnection during deinstallation. This dynamic connection system transitions from a permanently fixed state to an easily detachable state, resolving the contradiction between continuous support and ease of deinstallation.
4Stability of the object's composition
If the head rail extends along the entire width of the shade panel, then the window shade provides uniform coverage, but it increases the overall weight
Solution Approach 1:
The head rail is segmented into multiple sections that collectively span the full width of the shade panel, providing uniform coverage. However, because the segments are separate and can be handled individually, the effective weight that must be supported at any single point is reduced, and the total weight can be distributed more efficiently across the mounting structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enables easy installation, reduced weight, and simplified maintenance by eliminating the need for a fixed head rail, facilitating efficient operation and user-friendly handling.
Implementation Method 1
the roller lock rotationally locks the roller to prevent rotation of the roller relative to the first bracket
Implementation Method 2
the roller being pivotally connected to the first bracket

AI summary
A window shade comprises a shade assembly that includes a roller connected to a shade structure, and has a first end coupled to a first bracket and a second end having a coupler, the roller being pivotally connected to the first bracket. The first bracket is provided with a roller lock movable between a locking position where the roller lock rotationally locks the roller to prevent rotation of the roller relative to the first bracket, and an unlocking position where the roller lock rotationally unlocks the roller for rotation of the roller relative to the first bracket. Moreover, the window shade includes a connector and a second bracket attachable to a support surface of a building, wherein the first bracket and the coupler are respectively connected to the connector and the second bracket when the shade assembly is mounted to the support surface of the building.
