Sill Mounting System With Sloped Drainage And Overlapping Waterproof Layers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current window and door sill mounting systems fail to provide a watertight connection, leading to water damage and moisture ingress into building facades, especially in areas around window and door openings, due to inadequate sealing and drainage, which compromises insulation and causes visual and structural issues.
Innovation Solution
A soleplate receiving system with a sloping drainage surface, waterproof layers, and a profile frame support area that decouples the sill from direct contact with the mounting system, using adhesive beads and optional waterproof films to ensure effective water runoff and prevent moisture penetration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mounting systems are used to install window sills and frames, then installation is relatively simple, but water ingress through joints occurs leading to water damage and moisture penetration
Solution Approach 1:
The mounting system is divided into separate functional components: a sill mounting unit with drainage surface, multiple waterproof layers (first, second, and third waterproof layers), sill guides, and profile frame support areas. This segmentation allows each component to address specific aspects of water protection independently, achieving comprehensive waterproofing through coordinated operation of discrete elements rather than relying on a single complex sealing system.
Solution Approach 2:
The patent introduces intermediate elements such as the first waterproof layer positioned between the sill mounting unit and the profile frame, and the second waterproof layer on top of the sill mounting unit. These intermediary waterproof layers act as mediators that prevent direct water transmission paths, blocking moisture ingress at multiple intermediate stages before water can reach critical building structures.
2Object-affected harmful factors
If window sills are directly connected to mounting systems, then structural support is provided, but water and moisture can penetrate through joints causing damage to building facades and insulation
Solution Approach 1:
The sill mounting unit incorporates a downwardly sloping drainage surface and multiple waterproof layers as preliminary protective measures before water can reach vulnerable areas. The first waterproof layer is pre-positioned at the support area, the second waterproof layer is placed on top of the sill mounting unit, and the third waterproof layer covers the profile frame support area, creating pre-established barriers that prevent moisture penetration before damage can occur.
Solution Approach 2:
The patent adds vertical layering with multiple waterproof layers positioned at different heights and locations (first layer at support area, second layer on top surface, third layer at profile frame support area). This multi-dimensional approach to water protection creates overlapping barriers in the vertical dimension, preventing water ingress through joints by blocking potential penetration paths at multiple elevation levels.
3Reliability
If drainage openings are not provided, then the mounting system remains simple, but accumulated liquid escapes along profile sides causing water damage to masonry and facade
Solution Approach 1:
The drainage function is merged with the sill mounting unit itself through the downwardly sloping drainage surface integrated into the top surface of the unit. This integrated drainage surface combines the mounting function with water runoff functionality, directing water away from the building facade through the slope toward the front of the unit, eliminating the need for separate drainage components while preventing water damage.
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 system effectively prevents water damage by ensuring water drains away safely and prevents moisture ingress, maintaining insulation integrity and reducing the risk of frost and thermal bridge issues, while allowing for easy installation and integration with thermal insulation composite systems.
