Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drainage channels often accumulate water between the channel and the building's outer wall due to capillary forces, leading to potential damage, and existing solutions increase installation complexity and cost without effectively preventing this issue.
Innovation Solution
A drainage channel design with an inwardly curved side wall and ventilation openings to minimize contact surface area and prevent water accumulation, featuring a channel body with a floor and two side walls, where at least one side wall is curved and includes ventilation openings to ventilate the area between the channel and the building.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional drainage channels are installed directly against the outer wall, then installation is simple, but water accumulates due to capillary forces causing damage to the wall and channel
Solution Approach 1:
The invention extracts the problematic direct contact between the drainage channel and the outer wall by introducing an air gap through the curved side wall design. The inward curvature creates a ventilation space that separates the channel from the wall, eliminating the capillary action pathway while maintaining installation simplicity.
Solution Approach 2:
The side wall is designed with an inward curvature rather than a straight configuration. This curvature creates a ventilation space between the channel and the outer wall, preventing water accumulation by eliminating continuous contact surfaces that would allow capillary forces to act. The curved geometry achieves both the separation needed to prevent water damage and maintains structural integrity.
2Object-affected harmful factors
If spacers are used to separate the drainage channel from the outer wall, then water accumulation is prevented, but installation complexity and costs increase
Solution Approach 1:
The invention eliminates the need for separate spacer components by integrating the separation function directly into the channel structure through the curved side wall. The curvature itself creates the necessary ventilation space, removing the need for additional spacers and simplifying the installation process while still preventing water accumulation.
Solution Approach 2:
The functional separation previously requiring distinct spacer components is merged into the channel body structure itself. The curved side wall combines the structural function of the channel with the separation function, eliminating the need for additional spacer parts and reducing installation complexity.
3Object-affected harmful factors
If spacers are used to separate the drainage channel, then some water protection is achieved, but the spacers themselves contact the wall causing damage
Solution Approach 1:
The invention removes the intermediate spacer component that caused secondary damage by having the curved side wall create the ventilation space directly. This eliminates the spacer-to-wall contact problem while maintaining the water protection function through the air gap created by the curvature.
4Area of stationary object
If the side wall is curved inwardly, then contact surface area with the wall is reduced, but structural stability must be maintained
Solution Approach 1:
The inward curvature of the side wall reduces the contact surface area with the outer wall, preventing water accumulation. The curved design is engineered to maintain structural stability by distributing loads appropriately and providing sufficient rigidity to support the channel function while creating the necessary ventilation space.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively prevents the building's outer wall from being soaked by reducing the contact surface area and creating a ventilated space, thereby preventing damage and simplifying installation while maintaining structural stability.
Implementation Method 1
The at least one side wall has at least one ventilation opening for ventilating a space adjoining the outside of the first side wall
