Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drapery assemblies face issues such as manual operation requiring human effort, potential damage from tension, noise from motors, inefficiency due to indirect force application, and jerky motion from pulleys, along with aesthetically unpleasing wire routing and limited control options.
Innovation Solution
A drapery assembly with an electrically powered surface on the drapery rod, where carriers are held in movable linear mechanical restraint and equipped with position sensors, receiving electric power and position commands, and a controller using Power over Ethernet for efficient and controlled operation, allowing for smooth and coordinated movement of multiple carriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual pulling method is used to operate drapes, then the system is simple and low-cost, but it requires significant human effort and is impractical for large openings
Solution Approach 1:
The patent replaces the manual mechanical pulling system with an electrically powered carrier that moves along the drapery rod. The carrier uses an electric motor to provide the force needed to move the drape, eliminating the need for manual effort while maintaining system simplicity through direct drive architecture.
2Ease of operation
If pulley operated systems are used, then mechanical operation is achieved, but the motion becomes jerky and intermittent due to friction and slippage
Solution Approach 1:
The patent eliminates the pulley system entirely and uses an electrically powered carrier with a motor that directly drives the drape movement. This electrical drive system provides smooth, continuous, and precise motion control without the friction and slippage problems inherent in mechanical pulley systems.
3Measurement precision
If motors are mounted on primary carrier for direct drive, then control precision is improved, but wire routing becomes aesthetically unpleasing and prone to tangling
Solution Approach 1:
The patent extracts the power source from the moving carrier and places it in a stationary location. Power is transmitted to the carrier through the drapery rod itself using conductive elements embedded in the rod, eliminating the need for visible wires along the drape length and maintaining aesthetic appearance.
4Ease of operation
If tension is applied to move secondary carriers along drapery rod, then closing operation is achieved, but damage or premature wear occurs in the drape
Solution Approach 1:
The patent replaces the tension-based mechanical system with an electrically powered carrier that actively pushes or pulls secondary carriers along the rod. This controlled electrical drive system moves carriers without excessive tension, preventing drape damage while achieving reliable closing operation.

Data Source
AI summary
A drapery assembly extends and retracts a drape with a powered carrier. The carrier receives both a power signal and a command signal from a controller via an electrically powered surface of a drapery rod. The carrier supports a portion of the drape and moves linearly along the length of the drapery rod in response to the control signal.
