Retrofit Window Blind Automation Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional window blinds are difficult to operate and lack compatibility with Internet of Things (IoT) based controls, making them time-consuming and not 'smart' compatible.
Innovation Solution
A retrofit device that automates the operation of window blinds by attaching to a vertically adjustable pull bar, using reversible electrical motors with ball chains or toothed racks, and includes a control unit for smart phone app, Amazon Alexa, or Google Home control, with a rechargeable battery and photovoltaic cell for power, and a leveling sensor for horizontal alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional window blinds are used, then the structure is simple and inexpensive, but the operation is difficult and time-consuming
Solution Approach 1:
The patent replaces manual mechanical operation with an automated motorized system. Electric motors are integrated into the blind structure to automatically raise and lower the shade, eliminating the need for manual pulling and making the system compatible with smart home controls.
Solution Approach 2:
The blind system performs self-service through automated motorized operation. The motors automatically control the movement of the shade without requiring user intervention for basic operation, and the system can be controlled remotely via smartphone or voice commands.
2Adaptability or versatility
If conventional window blinds are used, then the device is simple, but it lacks compatibility with Internet of Things (IoT) based controls
Solution Approach 1:
The blind system is designed with multi-functionality to serve both traditional and smart home applications. It includes motorized actuation, wireless communication capabilities, and compatibility with multiple IoT platforms (Amazon Alexa, Google Home, smartphone apps), allowing it to function as both a conventional and smart device.
Solution Approach 2:
The patent introduces wireless communication modules and control electronics as intermediaries between the physical blind mechanism and digital smart home systems. These intermediaries enable the blind to receive and execute commands from IoT platforms while maintaining the mechanical structure of the original blind.
3Productivity
If automated motorized system is added to window blinds, then operation becomes easy and smart-compatible, but the device becomes more complex and expensive
Solution Approach 1:
The patent merges the motorized actuation system with the existing blind structure by integrating the motors directly into the blind mechanism. The control electronics and power management systems are combined into a unified assembly that works with the mechanical components, reducing overall system complexity despite adding automation capabilities.

AI summary
A retrofit device for automating a window blind having a shade operatively connected to a vertically adjustable pull bar. The device includes a housing and a fastener for attaching the housing to the pull bar. The device further includes a first track attachable to a window frame, a second track attachable to the window frame, a first drive at a first end of the housing and a second drive at a. second end of the housing. The first and second drives are operably engageable with the first and second tracks, respectively, for raising and lowering the pull bar and shade.
