Solution Overview

Problem

Existing methods for ensuring airtightness of technical conduits through construction elements, such as floors, are inefficient, requiring multiple components, being time-consuming, and not easily adaptable to varying construction element thicknesses, leading to suboptimal and non-reproducible results.

Innovation Solution

A reservation box with adjustable height connecting means, including threaded sections and notched sliding connections, allows for precise adjustment and assembly to match construction element thickness, ensuring airtightness around technical conduits and cables using elastic sealing elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple sealing components and interventions are used to ensure airtightness, then airtightness around the sheath and cable is improved, but the device complexity and time consumption increase

Engineering Contradiction:

ImproveairtightnessVSAvoidnumber of components

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple sealing functions into a single integrated sealing box structure that houses both the sheath seal and cable seal within one component, eliminating the need for separate rubber sleeves, membranes, and plugs while maintaining comprehensive airtightness

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The sealing box serves multiple functions simultaneously: it provides structural support for the sheath, seals around the sheath, guides the cable, and seals around the cable, making a single component perform what previously required multiple separate elements

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If traditional sealing methods are used, then airtightness can be achieved, but the adaptability to varying construction element thicknesses deteriorates

Engineering Contradiction:

ImproveairtightnessVSAvoidadaptability to thickness

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The sealing box incorporates adjustable height mechanisms that allow the structure to be dynamically adapted to different construction element thicknesses, transforming a static sealing solution into one that can be configured for various应用场景

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent enables adjustment of the sealing box height parameter to match different floor or wall thicknesses, allowing the same sealing design to be universally applied across varying construction specifications without compromising the seal

Inventive Principle:

Principle #35Parameter changes

3Reliability

If expanding foam is used to fill air inlets, then airtightness can be achieved, but the manufacturing precision and reproducibility deteriorate

Engineering Contradiction:

ImproveairtightnessVSAvoidreproducibility

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The patent replaces the chemical expanding foam method with a mechanical sealing structure that provides consistent, reproducible airtightness through precise engineering of the sealing box geometry and sealing surfaces, eliminating variability associated with foam expansion

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Device complexity

If a single-piece sleeve is used, then the device complexity is reduced, but the adaptability to all construction element thicknesses deteriorates

Engineering Contradiction:

Improvestructure simplicityVSAvoidadjustability to thickness

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The sealing box is divided into modular components including adjustable height sections that can be configured for different thicknesses, maintaining relative simplicity while enabling adaptability across various construction element dimensions

Inventive Principle:

Principle #1Segmentation
