Hygienic Hole Seal Assembly for Universal Chemical-Resistant Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hole seals fail to effectively seal pre-punched holes in enclosures, especially in hygienic industries, as they may allow moisture and pathogens to enter, and are not universally compatible with various hole diameters, and cannot withstand routine cleaning chemicals without degradation.
Innovation Solution
A hygienic hole seal system comprising a plate, a stud, a gasket, and a retaining member, where the gasket has a peripheral edge angled away from the stud, and a fastener that compresses the gasket against the enclosure wall, creating a sealing area and a non-sealing area to ensure a tight seal and prevent contamination, while being compatible with a range of hole diameters and resistant to cleaning chemicals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional hole seals are used to seal pre-punched holes in enclosures, then the sealing function is provided, but moisture and pathogens can still enter the enclosure and the seals degrade when exposed to cleaning chemicals
Solution Approach 1:
The hole seal employs a composite structure combining a rigid plate (metal or plastic) with a flexible gasket material. The rigid plate provides structural support and chemical resistance, while the flexible gasket creates the actual seal against moisture and pathogens. This composite approach allows the seal to withstand cleaning chemicals while maintaining effective sealing.
Solution Approach 2:
The gasket is designed with specific material properties including durometer hardness and cross-sectional geometry (such as rectangular or circular profiles) that enable it to deform and seal effectively. The plate thickness and gasket compression characteristics are engineered to maintain seal integrity under various cleaning conditions while preventing contaminant ingress.
2Reliability
If conventional hole seals are designed for specific hole diameters, then they can provide a seal, but they are not universally compatible with various hole diameters
Solution Approach 1:
The hole seal is designed as a universal component that can accommodate multiple hole diameters through adjustable mounting configurations. The plate can be positioned at different distances from the enclosure surface, and the gasket can be compressed to various degrees, allowing the same seal design to work with different aperture sizes while maintaining reliable sealing.
Solution Approach 2:
The seal incorporates flexible and adjustable elements that can adapt to different installation conditions. The plate-gasket assembly can be dynamically positioned and compressed to fit various hole diameters, transforming a static seal design into a dynamically adaptable solution that maintains seal integrity across different applications.
3Reliability
If the gasket is compressed against the enclosure wall to create a tight seal, then contamination is prevented, but the cleaning chemicals may degrade the gasket material
Solution Approach 1:
The composite design allows the rigid plate to bear the mechanical load and resist cleaning chemicals, while the flexible gasket focuses on creating the seal. This division of functional responsibilities protects the gasket from direct chemical degradation while maintaining seal tightness during compression.
Solution Approach 2:
Different materials are selected for different parts of the hole seal based on their specific functional requirements. The plate uses chemically resistant materials to withstand cleaning exposure, while the gasket uses elastomeric materials optimized for sealing performance. This localized material selection ensures each component performs its function while resisting the specific challenges it faces.
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 system provides a universal seal for various hole diameters, effectively prevents dust, water, and pathogens from entering, and withstands routine cleaning chemicals, ensuring high hygiene standards and operational efficiency in hygienic environments.
Implementation Method 1
The fastener is configured to threadingly engage the stud and be advanced along the stud to urge the retaining member against the enclosure wall, thereby urging a peripheral extension of the plate into the gasket, via compression of the gasket against an exterior surface of the enclosure wall.

AI summary
A hole seal is provided that can include a plate having a surface configured to face away from an enclosure wall of an enclosure, and a peripheral extension that is angled away from the surface. The hole seal can include a stud coupled to and extending away from the plate, a gasket, a retaining member configured to engage an enclosure wall of an enclosure opposite the gasket, and a fastener. The fastener is configured to threadingly engage the stud and be advanced along the stud to urge the retaining member against the enclosure wall, thereby urging a peripheral extension of the plate into the gasket, via compression of the gasket against an exterior surface of the enclosure wall.
