Sliding Window Retractable Screen With Clock-Spring Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Insect screens for sliding windows are redundant when not in use, obstructing the view and becoming dirty, and their service life is shortened due to exposure.
Innovation Solution
A retractable insect screen mechanism connected to the sliding window edge, retracting inside a housing when closed, using a clock-spring retraction system and guided by rollers, ensuring the screen is hidden and clean.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the insect screen is permanently installed on the sliding window, then it provides continuous insect protection, but it obstructs the view and accumulates dirt when not in use
Solution Approach 1:
The screen transitions from a static permanently installed state to a dynamic retractable state. The screen can be extended when insect protection is needed and retracted into the housing when not in use, allowing it to adapt between providing protection and maintaining a clean unobtrusive state.
Solution Approach 2:
The screen is nested within a housing structure that is integrated into the window frame. When retracted, the screen rolls into the housing, effectively hiding it and preventing dirt accumulation while maintaining the ability to extend for protection when needed.
2Ease of operation
If the insect screen is permanently installed and exposed to elements, then it is always accessible for use, but its service life is shortened due to exposure to dirt and debris
Solution Approach 1:
The screen is nested within a protective housing that shields it from environmental elements. When retracted, the screen is hidden inside the housing which protects it from dirt and debris, thereby extending its service life while remaining accessible when needed.
Solution Approach 2:
The screen is extracted from direct exposure to the external environment by placing it inside a housing structure. This extraction protects the screen from harmful environmental factors while maintaining its functionality when extended.
3Object-affected harmful factors
If the insect screen is retracted into a housing, then the view is preserved and screen is kept clean, but the device complexity increases
Solution Approach 1:
The screen is nested within a housing structure that is integrated into the existing window frame. This nesting approach consolidates multiple functions (protection, retraction, housing) into a single integrated structure, reducing overall complexity compared to separate components.
Solution Approach 2:
The housing structure is merged with the window frame, and the retraction mechanism is integrated into the housing. This combining of functions reduces the number of separate components and simplifies the overall device while achieving the desired protection and retraction functionality.
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
Preserves the outdoor view, maintains screen cleanliness, and extends its service life by keeping it out of sight when not in use.
Implementation Method 1
The insect screen will retract inside the housing using a clock-spring retraction mechanism located inside one of the end covers. One end of the clock-spring connects to the roller and the other end connects to the end cover.

AI summary
This concept addresses the redundancy of an insect screen while not in use and consists of a retractable insect screen connected in such way to the moving edge of a sliding window so that, when the window is opened—the screen gets pulled out to completely cover the window opening and, when the window is closed—the screen retracts inside its housing.
