Adjustable Window Screen Mounting Bracket with Resilient Finger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window screen assemblies face challenges in accurately matching the roller width to the window opening and fail to completely shut out light due to gaps between the screen and the window frame, with elongate support members requiring precise length matching and being prone to falling off if too short.
Innovation Solution
The screen assembly features a telescopically extendable elongate support member with resilient fingers and adjustable mounting brackets, allowing for centralization and secure fitting within the window opening, even with size discrepancies, and includes laterally extending flanges to cover gaps and ensure a flush fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the roller width is accurately matched to the window opening width, then the screen assembly can be mounted within the window opening, but the installation complexity increases and requires precise measurements
Solution Approach 1:
The support member is designed with an adjustable length parameter that can be modified after installation. The telescopic mechanism allows the support member to extend or retract to match the window opening width, eliminating the need for precise pre-matching and simplifying installation while ensuring reliable mounting.
Solution Approach 2:
The support member transitions from a fixed length design to a dynamic, adjustable length design. The telescopic mechanism enables the support member to adapt its length to fit different window openings, providing both ease of installation and reliable mounting without requiring precise pre-measurement.
2Reliability
If the elongate support member length is closely matched to the window opening width, then the recess can fit over the mounting bracket, but the support member may fall off if it is too short
Solution Approach 1:
The resilient finger is nested within the support member structure, allowing it to deform and provide a retaining mechanism. When the support member is installed, the resilient finger engages with the mounting bracket, creating a mechanical interlock that prevents the support member from falling off even if the length is not perfectly matched.
Solution Approach 2:
The resilient finger provides a cushioning or compensating mechanism that accommodates variations in support member length. The elastic deformation of the resilient finger absorbs the dimensional discrepancies, ensuring reliable retention without requiring high manufacturing precision for the support member length.
3Ease of operation
If gaps exist between the screen and window opening sides, then the screen assembly is easier to install with adjustable support members, but light cannot be completely shut out
Solution Approach 1:
The laterally extending flanges act as intermediary elements between the support member and the window opening sides. These flanges can be adjusted to fill the gaps laterally, blocking light leakage while maintaining the ease of installation provided by the telescopic support member. The flanges serve as a mediating structure that addresses both installation ease and light blocking requirements.
4Adaptability or versatility
If the mounting bracket position is fixed, then the structure is simpler, but the support member cannot be adjusted to fit various window sizes and shapes
Solution Approach 1:
The mounting bracket is designed with adjustable positioning capability, allowing it to move or reposition along the window opening. This dynamic adjustment feature enables the bracket to accommodate various window sizes and shapes while maintaining a relatively simple overall structure. The adjustability is achieved through mechanisms such as sliding or telescopic components integrated into the bracket design.

Function Achieved in This Case
This solution ensures reliable light blocking by centralizing the screen assembly and minimizing the risk of it falling off, while allowing for easy installation and adjustment to fit various window sizes and shapes, providing a secure and effective light-shielding solution.
Implementation Method 1
a resilient finger extending from a base portion of the recess and adapted to be biased against an outer face of a body portion of a mounting bracket when the support member is mounted onto the mounting bracket

AI summary
A screen assembly for a window comprising a screen supported by an elongate support member adapted to be mounted in an upper region of the window opening, a pair of mounting brackets being provided for attachment to respective sides of the window opening adjacent the top face of the window opening, each end of the elongate support member being provided with a recess adapted to receive a body portion of a respective mounting bracket such that the elongate support member may be engaged over the mounting brackets to retain the support member between the sides of the window opening, a respective biasing means being associated with each recess and/or body portion acting to provide a biasing force to urge the respective mounting bracket away from the respective recess in the adjacent end of the elongate support member, such biasing forces acting to centralise the elongate support member within the window opening.
