Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing technologies, such as carrier or metal-elastomer seals, are unable to produce seals for large components like battery boxes of electric vehicles due to size limitations of conventional injection molding tools and machines.
Innovation Solution
A modular sealing arrangement comprising interconnectable components with a dimensionally stable base body and an elastic sealing body, allowing for the connection of smaller components to form a larger sealing element, which can be produced using smaller injection molding tools and machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single large sealing element is produced using conventional injection molding, then the sealing performance is reliable, but the production is impossible due to size limitations of injection molding tools and machines
Solution Approach 1:
The sealing element is divided into multiple smaller sealing element components (first component, second component, etc.) that can each be produced using conventional injection molding tools and machines. These components are then connected to form the complete sealing element, enabling production of large seals that would otherwise exceed the capacity of standard injection molding equipment while maintaining reliable sealing performance.
2Area of stationary object
If multiple sealing element components are connected to form a large sealing element, then large-scale sealing applications become feasible, but the device complexity increases
Solution Approach 1:
The sealing element is divided into multiple smaller sealing element components (first component, second component, etc.) that can each be produced using conventional injection molding tools and machines. These components are then connected to form the complete sealing element, enabling production of large seals that would otherwise exceed the capacity of standard injection molding equipment while maintaining reliable sealing performance.
Solution Approach 2:
Multiple sealing element components are connected together through their base body parts to form a complete sealing element. The connection mechanisms (such as protrusions fitting into recesses, welding, or mechanical fastening) integrate the separate components into a unified structure that functions as a single large-scale sealing element, thereby achieving the required sealing area while managing complexity through standardized connection interfaces.
