Sliding Door Drainage with Segmented Hollow Post
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding doors and windows with drainage systems face issues where water accumulation occurs due to external pressure, leading to reduced water-tightness and potential inward water flow through drainage holes.
Innovation Solution
A sliding door or window design featuring a hollow sill post with drainage holes in both the upper and outward walls, incorporating a seal that divides the hollow post into compartments and a drainage valve to prevent wind-induced water intrusion, ensuring water flows through designated channels and maintaining water-tightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If drainage holes are provided in the upper wall of the sill post for water drainage, then water can drain from the sliding panel, but external wind pressure can force water inward through the same drainage holes
Solution Approach 1:
The hollow sill post is divided into multiple compartments by seals positioned at different heights. This segmentation creates separate drainage paths for different panels and prevents wind pressure from forcing water through the entire post, as each compartment can be sealed independently against inward pressure.
Solution Approach 2:
Seals are introduced as intermediary elements between the drainage holes and the internal cavity of the sill post. These seals act as mediators that allow water to drain outward while blocking wind pressure from forcing water inward through the drainage holes.
2Ease of manufacture
If the hollow post is used for drainage, then water can flow through the post structure, but the post gradually fills with water under external pressure
Solution Approach 1:
The hollow sill post is segmented into multiple compartments using seals at different vertical positions. This segmentation ensures that water can drain through the post while the seals prevent the entire post from filling up, maintaining reliability by limiting water accumulation to only the lowest compartment.
Solution Approach 2:
Seals are pre-installed in the hollow sill post to create preliminary barriers against wind pressure. These seals proactively prevent water from being forced inward through the drainage holes, counteracting the harmful effect of external pressure before it can cause water accumulation.
3Ease of operation
If drainage holes are provided on the inside of the door or window, then water can drain from the interior, but water can be blown inward via these holes under wind pressure
Solution Approach 1:
The interior drainage holes are segmented from the exterior drainage holes by seals positioned within the hollow sill post. This segmentation creates separate drainage pathways, allowing interior water to drain while the seals block wind pressure from forcing water through the exterior holes.
Solution Approach 2:
Seals serve as intermediary barriers between the interior and exterior drainage systems. These seals allow the interior drainage function to operate while simultaneously protecting against wind-induced inward water flow through the exterior drainage holes.
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 solution effectively prevents water accumulation and ensures longer-lasting water-tightness by directing water flow externally and sealing against wind pressure, preventing inward water entry.
Implementation Method 1
a seal (20) which divides the hollow outer post (10) into two compartments (21, 22)
Implementation Method 2
a drainage valve (30) which can seal an above-mentioned drainage hole (19) in the above-mentioned outward directed wall (17) of the sill post (5)
Implementation Method 3
When rain water or the like comes into contact with an above-mentioned panel or the like, this water will run through the above-mentioned drainage holes in the upper wall of the sill post and through the hollow post to the drainage holes in the outward directed wall of the sill post via which it is drained
