Solution Overview

Problem

Current fireguard devices with modular panels suffer from discontinuities in their coupling elements, allowing smoke, heat, and flames to pass through, and lack effective sound insulation, compromising their structural continuity and reliability.

Innovation Solution

Incorporating a central coupling portion with a female element in the male part and a male element in the female part within the panels' thickness, creating an additional obstacle and improving structural continuity, along with using composite materials that are poor heat conductors or reflectors, and adding intercalated elements for enhanced sound insulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional male-female coupling elements are used in fireguard devices, then the device can be assembled with modular panels, but the coupling zones create discontinuities that allow smoke, heat, and flames to pass through

Engineering Contradiction:
Improvemodular assemblyVSAvoidfire resistance
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent implements nested coupling by placing a second female element inside the first female element, and a second male element inside the first male element. This nested arrangement creates multiple blocking paths within the coupling zone, preventing smoke, heat, and flames from passing through while maintaining modular assembly capability.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent extends the coupling structure from a single-plane connection to a multi-dimensional blocking system by adding central coupling portions that protrude into the panel thickness. This creates three-dimensional blocking paths that effectively seal the coupling zones against fire and smoke penetration.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If coupling elements are added to connect modular panels, then the panels can be assembled together, but the coupling zones create structural discontinuities that compromise fire resistance

Engineering Contradiction:
Improvemodular configurationVSAvoidstructural continuity
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The coupling elements are pre-formed with specific geometries (male and female elements with defined protrusions and recesses) that ensure proper alignment and connection when panels are assembled. This preliminary preparation of coupling structures enables reliable modular assembly while maintaining structural continuity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The coupling elements are integrated as composite structural features within the modular panels, combining the panel material with protruding and recessed coupling portions. This creates a unified composite structure that maintains structural continuity across panel joints while enabling modular configuration.

Inventive Principle:
Principle #40Composite materials

3Device complexity

If simple coupling elements are used to join panels, then the device structure remains simple, but sound insulation between rooms is not achieved

Engineering Contradiction:
Improvecoupling structureVSAvoidsound transmission
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The nested arrangement of multiple male and female elements within the coupling zones creates multiple interfaces and air gaps that disrupt sound wave propagation. This nested structure provides effective sound insulation between rooms while maintaining a relatively simple overall coupling design.

Inventive Principle:
Principle #7Nested doll (Nesting)
