Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a sealing mat is designed for a specific pipe diameter, then the sealing precision is improved, but the adaptability to different pipe diameters deteriorates
Solution Approach 1:
The sealing mat is divided into multiple sealing projections arranged at different radial distances from the center line. Each sealing projection can independently contact the pipe outer surface at different positions, allowing the sealing mat to adapt to various pipe diameters while maintaining effective sealing contact.
Solution Approach 2:
Different sealing projections are positioned at specific radial distances to create localized sealing zones. This allows each projection to be optimized for contacting pipes of specific diameters, enabling the single sealing mat to provide precise sealing for multiple pipe size ranges through selective activation of different projections.
2Reliability
If the sealing mat is made from elastic material that can swell, then the sealing reliability is improved, but the device complexity increases
Solution Approach 1:
The sealing mat utilizes changes in material parameters (swelling and elastic deformation) in response to environmental conditions. When exposed to liquid, the elastomer material swells and the sealing projections deform elastically to conform to the pipe outer surface, automatically adapting to dimensional variations without requiring complex adjustment mechanisms.
Solution Approach 2:
The sealing mat performs self-adjustment through the swelling and elastic properties of the elastomer material. The material automatically deforms and conforms to the pipe surface when exposed to liquid, eliminating the need for external adjustment devices or complex installation procedures while ensuring reliable sealing.
3Adaptability or versatility
If multiple sealing projections are arranged at different radial distances, then the adaptability to different pipe diameters is improved, but the manufacturing complexity increases
Solution Approach 1:
Multiple sealing projections with different radial positions are integrated into a single sealing mat body made of elastomer material. This unified structure allows all projections to be manufactured simultaneously as one piece, simplifying production while providing the capability to seal pipes of different diameters through the coordinated action of multiple projections.
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 sealing mat provides a flexible and adaptable solution for sealing pipes of various diameters and shapes, ensuring a reliable and permanent seal by swelling upon contact with liquid, thus addressing the limitations of existing technologies.
Implementation Method 1
The material of the base body is preferably an elastic material suitable for sealing, in particular waterproofing. In particular, the base body is made of a building-sealing material. More preferably, the base body material is a material suitable for penetrations or pipe penetrations. These can be suitable plastic, rubber, silicone, and/or swellable materials.
