Hinged Window Shutter for Easy Maintenance and Weather Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window shutter designs are difficult to install, remove, and maintain, particularly when windows need replacement or cleaning, and they may not function effectively over time due to exposure to the atmosphere, with some designs being cumbersome to close from inside the house.
Innovation Solution
A window shutter system comprising a pair of shutters affixed to a wall adjacent to the window frame, with each shutter capable of swinging about a pivot axis via hinges, allowing for easy installation, removal, and operation, and featuring latches for secure closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the shutter is installed over the window frame, then the window is protected from extreme weather, but the window becomes difficult to clean or replace
Solution Approach 1:
The shutter assembly is divided into separate components: a shutter body and a window frame assembly. The shutter can be detached from the window frame, allowing the window to be cleaned or replaced independently while maintaining protection when the shutter is attached.
Solution Approach 2:
The shutter is designed to be removable from the window frame. The shutter can be extracted from the assembled structure, enabling easy access to the window for cleaning or replacement without permanent obstruction.
2Ease of operation
If the guide rail is secured above the window opening, then the shutter can slide along the rail, but the guide rail may not work effectively over time due to atmospheric exposure
Solution Approach 1:
The guide rail is removed from the exposed outdoor environment and relocated to the protected indoor space. This extraction from the atmospheric environment prevents weathering and extends the operational life of the guide rail mechanism.
Solution Approach 2:
The window frame assembly serves as an intermediary structure that houses the guide rail. This intermediary protection shields the guide rail from direct atmospheric exposure while still allowing the shutter to slide along the rail for operation.
3Reliability
If the shutter is designed to close from outside, then protection is provided, but it becomes difficult to close from inside the house
Solution Approach 1:
The shutter assembly is designed with multi-functionality, allowing it to be operated for closing from either the interior or exterior of the house. The window frame assembly and hinge mechanism enable bidirectional operation, providing universal accessibility for shutter closure.
4Reliability
If the shutter is permanently fixed to the window frame, then protection is continuous, but the window cannot be easily accessed for cleaning or replacement
Solution Approach 1:
The connection between the shutter and window frame is designed to be dynamic rather than static. The shutter can be attached to provide continuous protection, and detached when maintenance is needed, offering flexibility in adapting between protection mode and maintenance mode.

AI summary
A window shutter for securing windows. The window shutter comprises at least one first shutter and at least one second shutter. The first shutter is coupled to the second shutter via hinges. The first shutter is affixed to a wall and adjacent to a window frame. The second shutter is operable to swing about a pivot axis of the hinges. The second shutter is used to secure windows provided in the window frame.
