Screen Casing Fastening Assembly with Adjustable Height Brackets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for screen casings of large dimensions (above 3 meters) are not always suitable, leading to inadequate security, bending issues, and difficulty in securing the screen casing to structures under various circumstances, especially when direct fastening is not possible or energy considerations are a factor.
Innovation Solution
A fastening assembly with adjustable height brackets that can be used universally across different screen casings and circumstances, allowing for secure attachment to windows or doors by rotating and repositioning brackets to accommodate various mounting scenarios, using hook-on elements and elongate slots for precise alignment and screw fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple different fastening means are provided for different screen casing types and circumstances, then the security and suitability of fastening is improved, but the device complexity and number of components increases
Solution Approach 1:
The fastening bracket is designed to perform multiple functions: it can be mounted on different surfaces (wall or window frame), accommodate different screen casing positions, and provide secure fastening in various circumstances. This single universal bracket replaces the need for multiple specialized fastening means, resolving the contradiction between fastening security and device complexity
Solution Approach 2:
The fastening bracket incorporates adjustable elements that allow it to adapt dynamically to different mounting scenarios. The bracket can be positioned at various heights and angles, and the elongate slot allows for flexible positioning, enabling one bracket design to serve multiple fastening requirements without compromising security
2Stability of the object's composition
If the screen casing is fastened rigidly to prevent bending, then the structural stability is improved, but the adaptability to different mounting circumstances deteriorates
Solution Approach 1:
The fastening system is divided into separate components: the fastening bracket, the elongate slot, and the screw. This segmentation allows the bracket to provide rigid support for screen casing stability while the elongate slot and adjustable mounting positions provide flexibility for different installation circumstances. The rigid bracket structure prevents bending, while the segmented design enables adaptability
