Monolithic Cable Holder With Integrated Gasket for Dynamic Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing frameworks for cable penetrations in construction elements are inflexible and prone to deformation due to dynamic changes, such as water pressure or thermal expansion, leading to compromised sealing integrity, and require separate gaskets that can be misplaced or forgotten, undermining the sealing effectiveness.
Innovation Solution
A monolithic holder with an integrated gasket and flange, made of rubber or ceramifiable rubber, featuring air-enclosing structures and through-holes for easy installation, which accommodates thermal expansion and deformation while maintaining sealing integrity, eliminating the need for separate gaskets and sealants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate gasket is provided between the framework and construction element, then sealing can be achieved, but the gasket may be forgotten or misplaced, undermining sealing effectiveness
Solution Approach 1:
The gasket is integrated as an integral part of the framework, merging two previously separate components (framework and gasket) into a single monolithic structure. This eliminates the risk of the gasket being forgotten or misplaced during installation, while maintaining the sealing function between the framework and construction element.
2Strength
If frameworks are made of metal or engineering plastic, then structural strength is provided, but they are relatively inflexible and deform under dynamic pressure changes
Solution Approach 1:
The framework is made from elastomeric material, fundamentally changing the material parameter from rigid (metal/engineering plastic) to flexible. This allows the framework to accommodate dynamic pressure changes and deformation while maintaining structural integrity and sealing effectiveness.
3Temperature
If metal frameworks are exposed to heat, then thermal expansion occurs, causing unequal expansion with construction elements and leading to detachment or fracturing
Solution Approach 1:
The framework material is changed from metal to elastomeric material, which has different thermal expansion properties. This parameter change eliminates the unequal expansion issue with metal construction elements, preventing detachment and fracturing while maintaining sealing integrity under thermal conditions.
4Reliability
If rubber plugs are used to seal channels, then cable penetration sealing is achieved, but the plugs may loosen or leak when framework dimensions change
Solution Approach 1:
The sealing plugs are integrated as integral parts of the elastomeric framework, merging the plug and framework into a single monolithic structure. This eliminates the problem of plugs loosening or leaking when dimensions change, as the entire structure expands or contracts uniformly without relative movement between components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The holder provides reliable sealing and thermal insulation, accommodating dynamic changes without the need for additional gaskets or sealants, ensuring long-term integrity and fire resistance.
Implementation Method 1
Frameworks of an engineering plastic or of a metal are relatively inflexible when the construction element deform due to a changing dynamic situation. For instance, pressure on the construction element dynamically increased by water load may lead to such a deformation.
Implementation Method 2
The holder is provided with a gasket for placing the holder so that the gasket seals between the flange and an endless part of the construction element that completely surrounds the perimeter of the opening.
