Solution Overview

Problem

Existing fire-safe penetration seal systems for building apertures are difficult to install and require handling of multiple materials and small parts, making it challenging to easily reinstall or add pipes or lines without removing the entire sealing plug.

Innovation Solution

A system using block-shaped sealing elements with non-rectangular cross-sections, made from mineral fibers and a binding agent, which can be easily cut and adapted to fit different aperture sizes, featuring flexible and compressible properties for easy installation and enhanced frictional resistance, along with optional intumescent materials for improved fire resistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional fire-safe penetration seal systems are used, then fire resistance is maintained, but installation difficulty increases and reconfiguration becomes complex

Engineering Contradiction:
Improveinstallation easeVSAvoidfire resistance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The sealing system is divided into modular block-shaped elements that can be individually installed and configured. Each block contains fire-resistant material and can be independently positioned, allowing easy installation while maintaining fire resistance through the collective arrangement of multiple segments filling the aperture.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sealing blocks combine fire-resistant mineral fibers with binding agents to create composite material blocks that maintain fire resistance while being easier to handle and install compared to traditional monolithic sealing systems. The composite structure allows for pre-fabricated blocks with consistent fire performance.

Inventive Principle:
Principle #40Composite materials

2Ease of operation

If modular block elements are used, then installation ease improves, but structural complexity increases

Engineering Contradiction:
Improvehandling easeVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The aperture is divided into multiple block positions that can be filled with standardized modular elements. This segmentation allows simple handling of individual blocks while the overall system complexity is managed through the regular pattern of block arrangement and interlocking geometry.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular blocks are designed with universal dimensions and features that allow them to be used in various aperture configurations. Each block serves multiple functions: providing fire resistance, filling space, and interlocking with adjacent blocks, thereby reducing the need for specialized components and simplifying the overall system.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If traditional sealing plugs are used, then fire resistance is maintained, but reconfiguration requires complete removal

Engineering Contradiction:
Improvereconfiguration flexibilityVSAvoidmodification ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The sealing system uses discrete modular blocks rather than a monolithic plug, allowing individual blocks to be removed or repositioned without affecting the entire sealing structure. This enables easy reconfiguration for adding or moving pipes while maintaining fire resistance through the remaining blocks.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular block system transitions from a static monolithic plug to a dynamic reconfigurable assembly. Blocks can be independently moved, added, or removed to adapt to changing piping requirements, making the sealing system flexible and adaptable to future modifications.

Inventive Principle:
Principle #15Dynamics
