Motorized Window Shade Mounting Assembly with Concealed Wire Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for shipping, assembling, and installing shade tube assemblies often result in gaps between the shade and the wall surface due to off-site manufacturing and assembly, leading to inadequate coverage or excessive material usage.
Innovation Solution
A mounting assembly and fastening device system for roller window shades that includes a mounting bracket with a motor and a wire, where the wire is concealed within the bracket and motor, allowing for precise installation and minimizing visible wire length, facilitating accurate fitting and reduced material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If off-site manufacturing and assembly of shade tube assemblies is performed, then manufacturing efficiency is improved, but manufacturing precision deteriorates resulting in gaps between shade and wall surface
Solution Approach 1:
The system divides the shade tube assembly into separate components (shade tube, motor, mounting bracket) that are manufactured independently and assembled on-site. This allows each component to be manufactured with standard tolerances while achieving precise final fitment through the adjustable mounting bracket design.
Solution Approach 2:
The mounting bracket is designed with pre-configured wire passages and adjustment mechanisms that prepare the assembly for precise on-site installation. The wire is pre-routed through the bracket structure, allowing for accurate positioning without requiring complex off-site assembly procedures.
2Ease of manufacture
If greater tolerance is used in off-site manufacturing, then ease of manufacture is improved, but loss of substance increases due to excessive material usage
Solution Approach 1:
The mounting bracket incorporates adjustable elements that allow the final assembly dimensions to be dynamically modified on-site to match the exact window opening dimensions. This eliminates the need to manufacture brackets with excessive tolerance ranges, reducing material waste while maintaining manufacturing simplicity.
3Ease of operation
If wire is extended through the mounting bracket, then ease of operation is improved for motor connection, but visibility of wire increases affecting aesthetic appearance
Solution Approach 1:
The wire is nested within the mounting bracket structure, passing through internally defined passages that conceal the wire from external view. The motor connection is maintained through these hidden passages, allowing easy electrical connection while keeping the wire aesthetically concealed behind the bracket face.

AI summary
A mounting assembly for a roller window shade includes a mounting bracket, a motor coupled with a shade tube of the shade, and a wire. The mounting bracket includes a body having a first surface and a second surface and a protrusion fixedly coupled with the body and extending perpendicularly from the second surface. The first surface bears against a flat surface. A passage extends between the first surface and the second surface. The motor defines a recess that receives the protrusion. The wire extends through the passage and couples with the motor. The mounting bracket and the motor obscure the wire from view. The passage extends at least one of proximate and through the protrusion such that the wire extends into the recess when the wire is coupled with the motor and when the recess receives the protrusion.
