Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sealing doors against air leaks remains a persistent challenge, with existing solutions often interfering with door operation and requiring tools for installation or removal.
Innovation Solution
A flexible door seal device with a seamless design, featuring inner and outer flaps that overlap spaces between the door and jamb, corner pockets for self-retention, and the ability to be rolled or folded for easy transport and storage, ensuring a positive seal without tools or operational interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a door seal device is installed to prevent air leaks, then sealing effectiveness is improved, but door opening and closing operation may be interfered with
Solution Approach 1:
The door seal device is divided into multiple segments including a top portion, bottom portion, and side portions that can independently adapt to the door geometry. This segmentation allows the seal to conform to the door shape without creating rigid interference with door movement, while maintaining sealing effectiveness at multiple locations simultaneously.
Solution Approach 2:
The door seal device incorporates flexible materials and dynamic components that allow it to adapt its shape and position during door operation. The seal can dynamically adjust to maintain contact with the door and jamb while permitting smooth opening and closing motion, resolving the conflict between sealing reliability and operational ease.
2Manufacturing precision
If a door seal device requires tools for installation and removal, then installation precision is improved, but ease of installation deteriorates
Solution Approach 1:
The door seal device features self-retaining corner pockets that automatically secure the seal to the door without requiring external tools. The corners of the door insert into these pockets, providing self-positioning and self-securing functionality that achieves both ease of installation and sufficient precision through the self-aligning nature of the corner pockets.
3Ease of operation
If the door seal device is made compact for transport and storage, then ease of transport is improved, but sealing effectiveness may deteriorate
Solution Approach 1:
The door seal device can be collapsed or folded into a compact configuration for transport and storage, with portions nested within each other to minimize volume. When installed, the same components expand to their full operational dimensions to provide comprehensive sealing coverage, thus maintaining both compact storage capability and effective sealing performance.

AI summary
The flexible door seal device provides for sealing against air leaks around a door and doorway without interfering with door opening and closing. The flexible device is easily installed and removed without need of any tools. Also, the device can be rolled or folded into a compact size for transport and storage as needed. The device is self-retained until removed from a door. Retention is accomplished by way of the pockets disposed at each corner. Ideally, the device may be seamless. The device provides a positive seal by way of the insert and the inner flap and outer flap that overlap any space between a door and a jamb. The outer flap is sufficient to overlap drywall, trim, and other door surrounds.
