Quick Release Window Shade Module for Emergency Gravity Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window shade systems lack a quick and efficient mechanism to rapidly close shades, especially in emergency situations, and do not allow remote operation, which is crucial for security and convenience.
Innovation Solution
A quick release module with an electromechanical actuator and gear assembly that transitions between coupled and decoupled states, enabling rapid disengagement of the holding element from the lift mechanism, allowing the shade to fall under gravity to a closed position, and can be remotely activated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a traditional lift mechanism with holding element is used to control window shades, then the shade can be held at any position, but the shade cannot be quickly closed in emergency situations
Solution Approach 1:
The system transitions from a static holding mechanism to a dynamic quick-release mechanism. The electromechanical actuator enables the holding element to dynamically disengage from the lift mechanism, allowing the shade to rapidly descend under gravity when emergency closure is needed, while maintaining the ability to hold at any position during normal operation.
Solution Approach 2:
An electromechanical actuator serves as an intermediary component between the control system and the lift mechanism. This actuator mediates the transition between held and released states by engaging or disengaging the holding element from the lift mechanism, enabling quick closure without requiring direct manipulation of the entire lift system.
2Ease of operation
If manual control of window shades is used, then the system is simple to operate, but remote operation for security purposes is not possible
Solution Approach 1:
The patent replaces manual mechanical control with an electromechanical control system. The electromechanical actuator converts electrical signals from remote controls or building automation systems into mechanical motion to engage or disengage the holding element, enabling remote operation while maintaining operational simplicity through electronic interfaces.
3Loss of time
If the holding element remains engaged with the lift mechanism, then the shade can be precisely controlled, but rapid disengagement for emergency closure cannot be achieved
Solution Approach 1:
The holding element is pre-positioned and spring-loaded to engage with the lift mechanism, maintaining precise control during normal operation. The electromechanical actuator is pre-configured to rapidly disengage the holding element when activated, enabling emergency closure without compromising normal control reliability through the preliminary setup of engagement mechanisms.
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
Enables rapid and remote closure of window shades, enhancing security by quickly obscuring visibility and allowing for simultaneous control of multiple shades, improving safety and convenience.
Implementation Method 1
an electromechanical actuator configured to move the sliding gear assembly from the first axial position to the second axial position in response to receipt of a quick release signal
Implementation Method 2
the mesh gear meshes with the first gear and the sliding gear meshes with the spool gear to thereby transfer a torque from the first gear to the spool gear
Implementation Method 3
allowing the covering material and bottom rail to fall under the pull of gravity to an extended position

AI summary
Quick release systems for window shades for selectively disengaging and engaging a window shade holding element with a remainder of a lift mechanism of the window shade. When engaged, the shade functions normally, and when disengaged, the covering material of the window shade falls under the pull of gravity to an open position.
