Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing injection molding tools and machines are unable to produce carrier or metal-elastomer seals for battery boxes of electric vehicles due to their size and dimensions, limiting the production of reliable and cost-effective sealing arrangements.
Innovation Solution
A sealing arrangement comprising two or more sealing element components with a base body part and an elastic sealing body part, allowing for connection in a puzzle-like or form-fitting manner, which can be manufactured in smaller tools and machines, and includes complementary connecting sections for easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single large sealing element is produced using injection molding, then sealing reliability is improved, but manufacturing capability is exceeded due to size constraints of existing injection molding tools and machines
Solution Approach 1:
The sealing element is divided into multiple smaller sealing element components (first sealing element component, second sealing element component, etc.), each of which can be manufactured using existing injection molding tools and machines. These components are then connected to form the complete sealing element, thereby resolving the contradiction between producing a large reliable seal and the manufacturing capacity limits.
2Ease of manufacture
If multiple sealing element components are connected to form a complete sealing element, then manufacturing feasibility is improved, but assembly complexity increases
Solution Approach 1:
The sealing element components are designed with connecting sections that allow them to be connected in a puzzle-like or form-fitting manner. This merging of components through simple geometric interlocking reduces assembly complexity while maintaining manufacturing feasibility, as the components self-align and connect without requiring complex fastening mechanisms.
3Ease of operation
If sealing element components are designed with connecting sections for puzzle-like assembly, then ease of assembly is improved, but manufacturing precision requirements increase
Solution Approach 1:
The connecting sections are designed with asymmetric geometries that provide form-fitting connections. This asymmetry ensures proper orientation and alignment of the sealing element components during assembly, reducing the need for high manufacturing precision while maintaining ease of assembly. The unique geometric shapes guide the components into their correct positions.
