Projection-Cavity Component Joint for Thermal-Movement Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connections between components often fail to maintain a secure and reliable seal due to relative movements caused by different coefficients of thermal expansion and operational forces, leading to a deterioration of the sealing and connecting action.
Innovation Solution
A method involving a first component with a projection and a second component having a cavity, where a sealing and connecting material is introduced, and the projection engages into the cavity, forming an undercut configuration that compresses an elastic or solid sealing element upon separation, ensuring a consistent sealing and connecting action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional connecting technology is used to seal and connect two components, then the components can be joined together, but the connection fails to maintain secure sealing during operation due to relative movements caused by thermal expansion differences and operational forces
Solution Approach 1:
The patent applies parameter changes by utilizing the elastic properties of the sealing element and transforming mechanical energy into elastic deformation. The sealing element is designed to be compressible and elastic, allowing it to deform under operational forces and thermal expansion while maintaining continuous sealing contact. This transforms the rigid connection problem into a flexible, adaptive sealing solution that accommodates relative movements without compromising sealing reliability.
2Stability of the object's composition
If the components are rigidly connected to prevent relative movement, then connection stability improves, but the different coefficients of thermal expansion cause stress and potential failure
Solution Approach 1:
The patent applies dynamics by transitioning from a rigid, static connection to a dynamic, adaptive sealing system. The elastic sealing element continuously adjusts its deformation state in response to changing operational conditions and thermal expansion, maintaining optimal sealing pressure without creating stress concentrations. This dynamic adaptation allows the connection to remain stable while accommodating differential thermal expansion and operational forces.
3Ease of manufacture
If a simple sealing method is used, then ease of manufacture improves, but the sealing action deteriorates during separation or relative movement
Solution Approach 1:
The patent applies segmentation by separating the sealing function from the structural connection function. The elastic sealing element is introduced as a distinct component that specifically handles sealing, while the rigid components maintain structural integrity. This segmentation allows each element to be optimized for its specific function - the sealing element for adaptability and sealing consistency, and the rigid components for structural strength - thereby maintaining reliable sealing action throughout the component's operational life.
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
This configuration provides a secure and reliable sealing and connecting action even during relative movements, intensifying the sealing effect and minimizing porosity, unlike prior art where separation leads to a deterioration of the sealing action.
Implementation Method 1
provision is made for the projection to engage into the sealing and/or connecting material and to at least partially displace said material. In particular, the cavity may be fully filled with the sealing and/or connecting material at least after the joining-together of the first component and the second component.
Implementation Method 2
provision may in particular also be made for the projection to engage into the sealing and/or connecting material and to at least partially displace said material

AI summary
A method for the connection of a first component to a second component includes providing a first component which has a projection with an undercut, and providing a second component which has a cavity. The method also includes introducing a sealing and/or connecting material into the cavity of the second component, and joining the first component and the second component together to form a component arrangement. The projection of the first component projects, in the joined state, into the cavity of the second component.
