Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Chimneys with low exhaust gas temperature suffer from condensate formation, leading to acidic mixtures that damage the chimney and clog condensate drains, while existing solutions fail to protect the base plate and condensate collector from impact damage during cleaning, causing further blockages and maintenance complexities.

Innovation Solution

A chimney wastewater filter system comprising a filter housing with filter material, such as clay or carbon balls, that absorbs and filters wastewater, includes an impact protection mechanism to cushion falling objects, and a collar to direct water into the filter housing, ensuring delayed water release and preventing damage to the base plate and filter material.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a condensate collector with impact protection (bed of balls with ceramic plate) is used to protect the base plate from impact damage, then the base plate is protected from impact, but the impact can damage the ceramic plate and balls, creating fragments that clog the condensate drain

Engineering Contradiction:

Improveimpact resistance of base plateVSAvoidcondensate drain blockage risk

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The patent uses a flexible rubber ring instead of a rigid ceramic plate and loose balls. The rubber ring can deform to absorb impact energy from sweeping equipment while maintaining structural integrity, preventing the creation of fragments that would clog the condensate drain. This flexible element provides impact protection without the fragmentation problem of rigid materials.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The patent combines the rigid filter housing structure with a flexible rubber ring impact protection element. This composite approach integrates the protective function with the filter system, where the rubber ring absorbs impact while the rigid housing provides structural support and containment.

Inventive Principle:

Principle #40Composite materials

2Strength

If a prefabricated chimney inner pipe element with a bed of expanded clay spheres is used as impact protection, then the base plate is protected from impact, but the spheres can be damaged creating fragments that form slurry with wastewater and clog the condensate drain

Engineering Contradiction:

Improveimpact protectionVSAvoidslurry formation and condensate drain clogging

Core Design Contradiction:

StrengthVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the bed of expanded clay spheres with a continuous flexible rubber ring. This eliminates the discrete particles that can break into fragments and form slurry with condensate wastewater. The rubber ring maintains impact protection while preventing harmful fragment generation.

Inventive Principle:

Principle #30Flexible shells and thin films

3Ease of repair

If the filter housing is designed to be easily removable for maintenance, then maintenance complexity is reduced, but the system may not provide sufficient impact protection

Engineering Contradiction:

Improvemaintenance accessibilityVSAvoidimpact resistance

Core Design Contradiction:

Ease of repairVSStrength

Solution Approach 1:

The patent divides the filter housing into separable components that can be easily removed for maintenance, while the rubber ring impact protection remains integrated with the housing structure. This segmentation allows maintenance access without compromising the impact protection capability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent combines the impact protection function with the filter housing structure by integrating the rubber ring as part of the housing assembly. This merging ensures that impact protection is maintained even when the housing is designed for easy removal and maintenance.

Inventive Principle:

Principle #5Merging (Combining)
