Motorized Shade Bracket Power Connection for Concealed Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of motorized roller shades is challenging due to the difficulty in concealing power and data cables, which can cause noise, tangling, and electrical hazards, and requires extensive effort and cost to hide, with maintenance involving time-consuming disconnection and reconnection of wiring.
Innovation Solution
A system comprising a roller tube with a motor and shade material, a motor head locking member, and an installation bracket with guiding channels and contact pads, allowing for quick and easy detachable power and data connection through a concealed mechanism, minimizing exposure and maintenance complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If wires are concealed on top of the roller or behind it, then aesthetic appearance is improved, but installation time and effort increase
Solution Approach 1:
The system divides the wiring concealment task into separate functional components: the motor head unit contains the electrical connections, while the roller tube and mounting bracket handle the mechanical support and wire routing. This segmentation allows wires to be concealed within the motor head housing rather than requiring complex routing behind or over the roller, reducing installation time while maintaining aesthetic appearance.
2Shape
If wires are hidden behind the roller tube, then aesthetic appearance is improved, but wires may not be fully concealed from outside view
Solution Approach 1:
The motor head unit is nested within the roller tube assembly, with the electrical connections and wire entry points housed inside the motor head casing. The roller tube itself is nested within the mounting bracket structure. This nested arrangement ensures wires are concealed within the motor head housing, providing complete concealment from both inside and outside views while maintaining a clean aesthetic appearance.
3Reliability
If extensive wiring termination is performed, then reliable power and data connection is achieved, but installation complexity and time increase
Solution Approach 1:
The motor head unit incorporates self-contained electrical connections where power and data wires are terminated within the motor head housing itself. The motor head acts as a self-service unit that integrates the electrical termination, connection points, and wiring management, eliminating the need for separate wiring termination steps and reducing installation complexity while maintaining reliable connections.
4Ease of operation
If wires are exposed during installation, then wiring access is simplified, but electrical fire hazards and damage risks increase
Solution Approach 1:
The motor head unit is pre-configured with integrated wiring channels and connection points before installation. Power and data wires are routed through designated pathways within the motor head housing, and connections are established in advance during the wiring setup phase. This preliminary action ensures wires are properly concealed and protected before the shade is hung, reducing fire hazards while maintaining ease of wiring access during the initial installation.
5Ease of repair
If maintenance requires disconnection and reconnection of wiring, then shade can be cleaned and repaired, but maintenance time and complexity increase
Solution Approach 1:
The motor head unit is designed as a separable component that can be easily detached from the roller tube assembly. Electrical connections are extracted and integrated within the motor head housing, allowing the motor head to be removed as a complete unit for maintenance. This extraction design enables technicians to service the shade without dealing with separate wiring connections, reducing maintenance time and complexity while ensuring proper reconnection.

AI summary
Shade assembly comprising a roller tube, shade material connected to the roller tube, and a motor disposed inside the roller tube and adapted to rotate the roller tube to roll and unroll the shade material. The shade assembly further comprise a motor head disposed at a terminal end of the roller tube and comprises a contact pin and a first locking member, and an installation bracket adapted to be secured to an architectural structure and comprises a contact pad and a second locking member, wherein the motor head is stationary with respect to the installation bracket when the roller tube rotates. The motor head is adapted to removably attach to the installation bracket by connecting the first locking member to the second locking member and thereby aligning and electrically connecting the contact pin with the contact pad
