Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing condensate drainage systems for roof vents are complex, non-modular, and inflexible, often resulting in standing water and inability to adapt to varying roof structures, particularly with external insulation, and fail to reliably discharge condensation outside the building.
Innovation Solution
A modular condensate drain with a three-ring design featuring an inclined section for horizontal flow, adjustable during manufacturing, made from durable materials like PVC, metal, or concrete, allowing for easy adaptation and reliable drainage without standing water, suitable for both pitched and flat roofs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional condensate drainage systems are used, then condensation can be drained, but the systems are complex, non-modular, and inflexible, resulting in standing water and inability to adapt to varying roof structures
Solution Approach 1:
The drainage system is divided into three separate ring sections (first, second, and third ring sections) that can be independently manufactured and assembled. Each ring section has a standardized diameter and can be fitted around the ventilation pipe, allowing modular adaptation to different roof structures while maintaining simple individual components
Solution Approach 2:
The ring sections are designed with universal dimensions and standardized features that allow them to be used with different types of ventilation pipes and roof structures. The first ring section connects to the ventilation pipe, the second provides the inclined drainage surface, and the third collects and channels water, creating a multi-functional modular unit that adapts to various installation situations
2Adaptability or versatility
If fixed special components are used for condensate drainage, then drainage function is provided, but the components cannot be individually adapted to respective installation situations and roof constructions
Solution Approach 1:
By segmenting the drainage system into three standardized ring sections, each component can be manufactured using the same production process and tooling, maintaining manufacturing simplicity while enabling adaptation through modular assembly rather than custom fabrication for each installation
Solution Approach 2:
The ring sections are designed with adjustable parameters within standardized ranges - the inclined section can be manufactured with different inclination angles, and the ring dimensions accommodate various pipe sizes, allowing adaptation to different installation situations without requiring completely custom components
3Object-affected harmful factors
If condensation is collected in standing water, then drainage is provided, but unhygienic standing water forms and increases risk of icing and odor formation
Solution Approach 1:
The second ring section creates an inclined drainage surface that directs condensate toward the third ring section, eliminating standing water by maintaining continuous water flow. The inclined geometry ensures that condensate always moves toward the discharge opening, preventing accumulation that would create hygienic problems and icing risks
Solution Approach 2:
The drainage system uses the natural flow of condensate under gravity to self-drain without requiring additional pumps or active mechanisms. The inclined surface and ring geometry automatically guide water from the ventilation pipe through the drainage path to the discharge opening, providing continuous movement that prevents standing water formation
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 modular design ensures efficient and hygienic condensate drainage outside the building, adaptable to different roof constructions, with low manufacturing costs and long service life, preventing water from entering the building and reducing the risk of icing and odor formation.
Implementation Method 1
The ring (10) has a shoulder (14, 15) inclined to the horizontal, along which the condensate that forms can flow to an opening (22) in the ventilation pipe
