Pivoting Arc Cover Profiles for Vertical Door Edge Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door sealing technologies fail to effectively seal the vertical secondary closing edge of door leaves, allowing air leakage and posing a risk of finger injury when the door is closed, and often require fixed installation.
Innovation Solution
A modular device comprising a frame attachment profile, wing attachment profile, and cover profiles with circular arc cross-sections that pivot to cover the gap between the door leaf and frame, allowing for easy attachment and adaptation to different door configurations, ensuring a secure seal and finger protection without being fixed to the ground.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ground-fixed sealing devices are used, then sealing effectiveness is improved, but installation complexity and adaptability to different door configurations deteriorate
Solution Approach 1:
Instead of fixing the sealing device to the ground, the patent inverts the attachment approach by fixing it to the door leaf itself. The L-shaped bracket attaches to the door leaf via screws, and the seal arm pivots relative to the bracket, allowing the sealing mechanism to move with the door while maintaining effective contact with the door frame.
Solution Approach 2:
The sealing device incorporates dynamic elements including a pivot joint that allows the seal arm to rotate relative to the L-shaped bracket, enabling the seal to adapt to the door's movement and maintain contact pressure. The spring element provides dynamic force to ensure continuous sealing contact.
2Reliability
If ground-fixed sealing devices are used, then sealing effectiveness is improved, but adaptability to different door sizes and designs deteriorates
Solution Approach 1:
The sealing device is divided into separate modular components: an L-shaped bracket, a seal arm, a spring element, and mounting hardware. This segmentation allows each component to be independently adjusted and configured for different door sizes and designs, while maintaining effective sealing performance.
Solution Approach 2:
The device allows adjustment of geometric parameters including the position of the pivot joint, the spring force, and the mounting location on the door leaf. These parameter changes enable adaptation to various door configurations while maintaining sealing effectiveness.
3Reliability
If the door leaf thickness is increased to improve sealing, then sealing effectiveness is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent uses a flexible seal arm that can bend and conform to the door frame surface, providing effective sealing without requiring thick door leaves. The flexible nature of the seal arm allows it to maintain contact pressure and adapt to surface irregularities.
