Torsional Vibration Damper Seal Structure for Low-Cost Fluid Retention

The patent replaces the expensive elastomer-metal seal with a simpler, more cost-effective sealing solution that uses readily available materials and standard manufacturing processes, accepting that the seal may need replacement over time but significantly reducing initial manufacturing costs

The patent modifies the sealing approach by changing from a complex elastomer-metal composite seal to a simpler sealing structure that uses different material parameters and sealing mechanisms, achieving adequate sealing performance through alternative means that are less costly to manufacture

The patent adopts a simpler sealing component that can be manufactured more quickly using standard processes, reducing the time required for production while maintaining sufficient sealing performance for the application requirements

The patent extracts the sealing function from the complex elastomer-metal seal structure and implements it through a simpler, standalone sealing component that requires less manufacturing time and can be produced more efficiently

The patent replaces the complex plastic-metal seal structure with a simpler sealing component that uses fewer materials and a more straightforward design, reducing device complexity while maintaining adequate sealing effectiveness for the torsional vibration damper application

The patent inverts the sealing approach by moving away from complex composite structures toward a simpler, more direct sealing solution that achieves the required effectiveness through a different, less complex structural configuration
