Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing methods for pipes and cables in safety rooms are inadequate for withstanding high pressure and shock, and are not easily operable in emergency situations, particularly in the context of explosion-proofing and biological hazards.
Innovation Solution
A sealing system comprising a metal plate with threaded openings for passing pipes and cables, combined with an auto-seal zero-pressure check valve and a sealing nipple, which uses O-rings and spring mechanisms to ensure tight sealing and easy operation, including a flare nut and Dowty seal for enhanced sealing capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If rubber or harden ointment sealing is used for pipes and cables passing through walls, then installation is simple, but sealing effectiveness against high pressure and shock is insufficient
Solution Approach 1:
The sealing system is divided into multiple functional components: a sealing frame with modular sealing elements, compression units with adjustable pressure distribution, and expansion units for adaptive sealing. This segmentation allows each component to perform its specific function optimally while maintaining overall sealing effectiveness under high pressure and shock conditions.
Solution Approach 2:
The sealing system employs composite construction combining rigid sealing frames (for structural integrity under pressure) with flexible sealing elements and elastomeric expanders (for adaptive sealing). This composite approach integrates the advantages of different materials to achieve both installation simplicity and high reliability under extreme conditions.
2Ease of manufacture
If traditional sealing methods are used for water draining pipes, then installation is straightforward, but operation during emergency situations is difficult
Solution Approach 1:
The compression unit is designed as a removable component that can be extracted from the sealing assembly. This allows maintenance personnel to access and service the water draining pipe and check valve without dismantling the entire sealing system, significantly improving emergency operation accessibility while maintaining straightforward installation.
Solution Approach 2:
The sealing system incorporates dynamic accessibility features where non-critical sealing components can be temporarily removed or adjusted to access emergency controls. This dynamic design enables easy operation during emergencies while maintaining the simplicity of initial installation.
3Adaptability or versatility
If multiple pipes and cables are passed through walls for air conditioning systems, then functional requirements are met, but sealing complexity increases
Solution Approach 1:
The sealing frame is designed as a universal platform that can accommodate multiple types of utilities (cables, pipes, drainage) through standardized openings and modular sealing elements. This multi-functional design meets diverse functional requirements while maintaining consistent sealing principles, thereby controlling overall system complexity.
Solution Approach 2:
The sealing system employs nested modular elements where smaller sealing components are integrated within the larger sealing frame structure. This nesting approach allows multiple utilities to be sealed within a unified system architecture, managing complexity through hierarchical organization rather than separate independent sealing systems.

AI summary
A sealing set may be used for sealing and draining a liquid and may comprise a check valve and a mating press unit. When the check valve and the mating press unit may be separated, the check valve may be sealed and may prevent flow of liquid or gas from the first end to the second opening, and when the mating press may be pressed against the check valve so that the third end is inserted into the second end, a flow of liquid or gas may be opened between the two ends. The check valve may comprise a hollow elongated cylinder; a sealing gasket; and a mass and a pressing means configured to press the mass against the sealing gasket for sealing an end. The press unit may comprise a second hollow elongated cylinder and may include one or more holes on the third end perimeter.
