Solution Overview

Problem

Existing systems for draining rainwater from gutters in building murals require cleaning the ends of the windowsill, which is labor-intensive and can lead to moisture damage and restricted spatial flexibility in window installation.

Innovation Solution

A water yield system that includes a collecting section within the gutter to gather rainwater and a spitting section that directs the water onto the windowsill, eliminating the need for the windowsill to absorb water from the gutter.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the ends of the window sill are plastered into the reveal to drain rainwater, then rainwater drainage is achieved, but additional plastering work is required and moisture damage can occur

Engineering Contradiction:
Improverainwater drainageVSAvoidplastering work
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The invention divides the drainage function into separate components: the gutter system handles rainwater collection and the window sill handles structural support, eliminating the need for plastering the window sill ends into the reveal. The gutter is segmented to include collection and drainage sections that work independently of the window sill installation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The drainage function is extracted from the window sill structure and assigned to the gutter system. By removing the requirement for the window sill to be plastered into the reveal for drainage purposes, the invention eliminates the harmful plastering work while maintaining effective rainwater drainage through the gutter's dedicated drainage section.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If the ends of the window sill are plastered into the reveal, then rainwater drainage is achieved, but moisture penetration and damage to plaster can occur

Engineering Contradiction:
Improverainwater drainageVSAvoidmoisture damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The drainage function is extracted from the window sill structure and assigned to the gutter system. By removing the requirement for the window sill to be plastered into the reveal for drainage purposes, the invention eliminates the harmful plastering work while maintaining effective rainwater drainage through the gutter's dedicated drainage section.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The gutter system acts as an intermediary between the rainwater and the window sill structure. It collects and channels rainwater away from the building, preventing direct contact between water and the window sill or surrounding masonry, thus eliminating moisture damage risks associated with plastered ends.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the window sill is plastered at both ends, then rainwater can be drained, but the window sill cannot be easily replaced if damaged

Engineering Contradiction:
Improverainwater drainageVSAvoidwindow sill replacement
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The invention divides the drainage function into separate components: the gutter system handles rainwater collection and the window sill handles structural support, eliminating the need for plastering the window sill ends into the reveal. The gutter is segmented to include collection and drainage sections that work independently of the window sill installation.

Inventive Principle:
Principle #1Segmentation

4Reliability

If the window sill is plastered into the reveal, then rainwater drainage is achieved, but the installation height of the window sill is limited

Engineering Contradiction:
Improverainwater drainageVSAvoidinstallation flexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The invention divides the drainage function into separate components: the gutter system handles rainwater collection and the window sill handles structural support, eliminating the need for plastering the window sill ends into the reveal. The gutter is segmented to include collection and drainage sections that work independently of the window sill installation.

Inventive Principle:
