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

VSEngineering 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

Engineering Contradiction:
Improveexternal appearanceVSAvoidassembly complexity
Core Design Contradiction:
ShapeVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #15Dynamics

2Ease of manufacture

If the panel structure is made simple, then production costs are reduced, but the adaptability to local conditions decreases

Engineering Contradiction:
Improveproduction costsVSAvoidadaptability to local conditions
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #1Segmentation

3Reliability

If multiple fastening points are provided, then the secure attachment is improved, but the device complexity increases

Engineering Contradiction:
Improvesecure attachmentVSAvoidnumber of parts
Core Design Contradiction:
ReliabilityVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)
