Keder Sheet Device Channels for Roof Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Keder roof systems are prone to rainwater leakage, which can cause issues due to the need to maintain the interior dryness for various applications, and existing solutions do not effectively prevent water from contacting the keder rails.
Innovation Solution
A keder sheet device with keder sheet forcing elements and attachment mechanisms that form channels to direct rainwater away from the keder rails, ensuring the system remains non-leaking without altering the existing construction, and can be attached at any suitable position to optimize drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional keder roof systems are used, then the system provides temporary weather protection, but rainwater leaks inside the system by contacting the keder rails
Solution Approach 1:
A drainage system comprising drainage members is introduced as an intermediary between the keder sheet and the keder rails. This drainage system intercepts rainwater before it can reach the keder rails, preventing leakage while maintaining the traditional keder roof structure. The drainage members act as a mediating layer that manages water flow away from critical components.
Solution Approach 2:
The drainage system is divided into multiple discrete drainage members that can be individually positioned and attached to the keder rails. These segmented drainage elements work collectively to channel water away, providing effective waterproofing through distributed water management rather than a single continuous barrier.
2Reliability
If the entire construction, proportions and structure of the keder roof system are changed to prevent leakage, then waterproofing may improve, but the system complexity and manufacturing cost increase
Solution Approach 1:
The drainage system consists of multiple individual drainage members that can be independently manufactured and attached to existing keder rails. This segmented approach allows the waterproofing function to be added without redesigning the entire keder roof structure, maintaining simplicity while improving reliability.
Solution Approach 2:
The drainage members serve as intermediary components that bridge the existing keder sheet and rail structure without requiring fundamental changes to either. This intermediary approach enables waterproofing enhancement while preserving the original system's simple construction and proportions.
3Object-affected harmful factors
If drainage components are added to prevent water contact with keder rails, then leakage prevention improves, but the device complexity increases
Solution Approach 1:
The drainage members are positioned specifically at locations where water would naturally flow toward the keder rails. Rather than adding complexity throughout the entire system, the drainage components are strategically placed only where needed to intercept water flow, providing effective protection with minimal additional components.
Solution Approach 2:
The drainage members are simple intermediary elements that can be attached to existing keder rails without requiring complex integration with other system components. Each drainage member independently performs the water interception function, allowing the system to achieve leakage prevention through multiple simple, identical components rather than a single complex assembly.
