Door Gap Cover with Displaceable Fastening Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for covering the gap between a garage door frame and the reveal lack flexibility and ease of assembly, making them difficult to adapt to local conditions and increasing production costs due to complex structures and multiple parts.
Innovation Solution
A screen with a longitudinally displaced fastening element in a channel on the screen body, allowing for flexible adaptation and easy assembly, featuring a fastening tab for attachment to the reveal and frame, and a simple, cost-effective design with a one-piece channel and L-shaped legs for optimal alignment and secure fixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a panel is used to cover the gap between the frame and reveal, then the external appearance is improved, but the assembly complexity increases
Solution Approach 1:
The fastening element is integrated directly into the panel structure, merging the fastening function with the covering function into a single component. This eliminates the need for separate fastening parts and simplifies assembly while maintaining the aesthetic covering of the gap between frame and reveal.
Solution Approach 2:
The fastening element is designed to be displaceable along the longitudinal axis of the panel, allowing dynamic adjustment during assembly. This enables flexible positioning to accommodate local conditions on site while maintaining a simple overall structure, resolving the contradiction between adaptability and complexity.
2Ease of manufacture
If the panel structure is made simple, then production costs are reduced, but the adaptability to local conditions decreases
Solution Approach 1:
The displaceable fastening element provides dynamic adjustment capability within a simple panel structure. This allows the panel to adapt to varying local conditions during installation without requiring complex pre-configured features, maintaining both simplicity and adaptability.
Solution Approach 2:
The fastening element is segmented from the main panel body, allowing it to be positioned and adjusted independently along the longitudinal axis. This segmentation enables adaptability to different installation conditions while keeping the overall panel design simple and cost-effective to manufacture.
3Reliability
If multiple fastening points are provided, then the secure attachment is improved, but the device complexity increases
Solution Approach 1:
Multiple fastening points are achieved by integrating multiple fastening elements into the single panel structure. Each fastening element can be positioned at different locations along the longitudinal axis, providing multiple attachment points without requiring separate complex fastening systems. This maintains secure attachment while minimizing the number of distinct parts.

AI summary
The cover (14) has an elongated cover body (17) with a visible side (15) facing the gap, and a rear side (16). A longitudinally running channel (24) is provided on the rear side of the cover body and a fastening body (20) is movably hold in the channel. The fastening body has a fastening lug protruding from the channel for fixing at a jamb (11). The channel is integrally formed with the cover body.
