Screen Covering Drip Guard for Lateral Gutter Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen coverings face challenges in effectively draining precipitation along their lateral sides without hindering the folding mechanism, leading to dripping issues due to insufficient inner side wall height and desired steeper inclinations for front drainage.
Innovation Solution
A downwardly extending drip guard is integrated into the screen covering, which is foldable and extends beyond the cross-beams, guiding precipitation towards a lateral gutter and reducing adhesive sticking, while being easily foldable without wrinkling or twisting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the inner side wall of the lateral gutter is made sufficiently high to ensure precipitation is kept inside, then precipitation retention is improved, but the screen cannot fold above the lateral gutter
Solution Approach 1:
The lateral gutter is divided into two functional parts: a fixed outer side wall that provides structural support and a movable inner side wall that can shift position. This segmentation allows the inner side wall to move out of the way during screen folding while remaining in place to retain precipitation during operation
Solution Approach 2:
The inner side wall of the lateral gutter is made movable rather than fixed, allowing it to dynamically adjust its position. During normal operation, it remains in position to prevent precipitation overflow; during folding, it moves to clear the screen's path
2Ease of operation
If the screen is arranged at a certain distance from the inner side wall of the lateral gutter to enable folding, then screen folding is improved, but precipitation drips along the lateral sides of the screen
Solution Approach 1:
A drip guard is introduced as an intermediary element between the screen and the lateral gutter. This drip guard extends downward from the screen's lateral side and actively redirects precipitation that would otherwise drip outside the gutter, channeling it into the gutter instead
3Productivity
If the lateral gutter is arranged with the inner side wall underneath the screen, then precipitation drainage is improved, but the screen cannot fold above the lateral gutter
Solution Approach 1:
The lateral gutter structure is segmented into a fixed outer side wall and a movable inner side wall. The fixed outer wall maintains the drainage function by staying positioned underneath the screen, while the movable inner wall can shift to allow screen folding
Solution Approach 2:
The inner side wall is made dynamic rather than fixed, allowing it to move out of the folding path when needed while maintaining its drainage position during normal operation. This dynamic adjustment resolves the conflict between drainage efficiency and folding capability
