Magnetic Protective Frame for Large Windows and Doors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing magnetic frames for large windows and doors are insufficiently fixed, prone to unintentional removal, and require structural reinforcement to maintain integrity, especially for dimensions like 1300x3000mm, while preserving the original design and aesthetics.
Innovation Solution
A perimeter frame with distributed magnetic elements, fixing and alignment squares at the corners, and a non-contacting design to ensure robust adhesion and easy removal, using neodymium magnets and lightweight materials like aluminum.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic elements are placed only in the corners of the frame, then the structure is simpler and lighter, but the adhesion is insufficient for large spans
Solution Approach 1:
The magnetic fixation system is segmented into multiple individual magnetic elements distributed along the entire perimeter of the protective frame, rather than using a single continuous magnetic strip. This segmentation allows the frame to adhere at multiple discrete points, significantly improving adhesion reliability for large spans while maintaining structural simplicity through modular magnetic element placement.
2Reliability
If magnetic strips are used along the perimeter frame, then adhesion is improved, but the structure becomes too heavy for large spans
Solution Approach 1:
Instead of using continuous magnetic strips that would add excessive weight, the solution segments the magnetic fixation into multiple individual magnetic elements spaced along the perimeter. This segmentation maintains adequate adhesion force distributed across multiple attachment points while significantly reducing the total weight compared to continuous magnetic strips, making it suitable for large span applications.
3Strength
If the protective frame is made robust for large dimensions, then structural integrity is improved, but removal becomes difficult and may cause damage
Solution Approach 1:
The mechanical fixation system is replaced with a magnetic fixation system where individual magnetic elements provide the necessary holding force for structural integrity, but can be easily overcome by deliberate user action. This substitution allows the frame to remain securely fixed during normal use while enabling simple removal when needed, avoiding damage to the underlying structure.
4Stability of the object's composition
If the frame uses heavier materials for reinforcement, then structural stability is improved, but the minimalist design and aesthetics are compromised
Solution Approach 1:
The protective frame utilizes composite construction combining lightweight materials (such as aluminum or composite profiles) for the frame structure with strategically placed magnetic elements for fixation. This composite approach provides sufficient structural stability for large dimensions while maintaining the lightweight, minimalist aesthetic design, avoiding the need for heavy reinforcement materials that would compromise the visual appearance.

AI summary
The present invention relates to a protection frame for large frames, this protection frame aims to minimize pollution inside buildings through the placement of protective panels of specific types. The present invention comprises a perimeter frame (1) that surrounds a protective panel and has two parts: a magnetic part, which has embedded inside a plurality of magnetic means (2) and adheres by magnetism to the fixed frame of the window or door; and a non-magnetic part that incorporates the protective panel and is superimposed on the perimeter of vent, but does not contact it, avoiding damage. The perimeter frame (1) has fixing squares (3) located on the non-magnetic part, and alignment squares (5) located on the magnetic part, in this way the structure is reinforced and can thus increase the size of the job site rough opening / windows / doors.
