Angled Front Flap Trim Seal for Garage Door Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional overhead garage door trim seals are prone to bowing or separation from the door frame due to improper installation or weather and thermal effects, leading to inefficiencies in sealing gaps between the door and frame, and often require additional costly installation steps and materials.
Innovation Solution
A single-piece trim seal apparatus with a lengthwise body featuring a ribbed surface and a front flap oriented at an angle to contact the door frame, providing effective sealing without the need for complex multi-part systems or additional caulking, and can be easily installed to seal both the garage door and the door frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional trim seal is installed to seal the gap between door and frame, then air and water infiltration is reduced, but the trim seal tends to bow or separate from the door frame over time
Solution Approach 1:
The trim seal is divided into multiple segments or sections that can independently adjust to thermal expansion and contraction, preventing bowing and separation while maintaining continuous sealing contact with both the door and frame
Solution Approach 2:
The trim seal incorporates dynamic adjustment mechanisms that allow it to move and adapt to changes in door and frame dimensions due to thermal effects, ensuring the seal remains taut and effective without bowing or separating
2Object-affected harmful factors
If additional caulking is applied to seal gaps in the trim seal, then sealing effectiveness is improved, but installation complexity and material costs increase
Solution Approach 1:
The trim seal integrates multiple sealing functions into a single component, combining the door seal, frame seal, and gap sealing into one unified structure that eliminates the need for separate caulking materials and installation steps
Solution Approach 2:
The trim seal is designed to perform multiple sealing functions simultaneously - sealing between the door and frame, sealing gaps at the trim seal edges, and accommodating thermal expansion - all within a single component design
3Object-affected harmful factors
If conventional trim seal is used, then some air flow resistance is provided, but thermal inefficiencies and noise transmission remain
Solution Approach 1:
The trim seal uses composite materials with different thermal properties that provide both air flow resistance and thermal insulation, reducing thermal inefficiencies and noise transmission while maintaining effective sealing

AI summary
A trim seal apparatus has a lengthwise body having a face surface and an opposite ribbed surface each spanning between a front surface and an opposite rear surface of the body and a lengthwise front flap extending at an angle in the direction of the ribbed surface from a location along the front surface that is at least midway between the face surface and the ribbed surface or that is closer to the ribbed surface than the face surface, in use when the body is installed on the door frame with the ribbed surface directly against the door frame the front flap is oriented toward and configured to make sealing contact against the door frame so as to seal the garage door opening between the body and the door frame.
