Solution Overview
Problem
The existing hydraulic mounts for vehicles with dual orifice structures face issues such as the formation of joints due to reinforcement plates, increased assembly processes, and higher costs and weights, which hinder productivity and size optimization.
Innovation Solution
A hydraulic mount design that integrates the membrane and orifice upper plate as a single component, using a vulcanization process to form a serpentine inertia track and secondary orifice apertures, eliminating the need for a reinforcement plate and reducing the number of assembly steps and components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a reinforcement plate is used in the membrane structure, then structural strength is improved, but joint formation occurs and assembly complexity increases
Solution Approach 1:
The patent merges the membrane and orifice upper plate into a single integrated component formed by vulcanization molding. This eliminates the need for separate reinforcement plates and reduces the number of joints and assembly steps, while maintaining structural strength through the integrated design
2Stability of the object's composition
If multiple separate components are used, then structural integrity is maintained, but manufacturing cost and weight increase
Solution Approach 1:
The membrane and orifice upper plate are combined into a single vulcanized component, reducing the total number of parts. This integration eliminates the weight of separate reinforcement plates and fasteners while maintaining structural integrity through the molded design
Solution Approach 2:
The patent uses composite material construction with the membrane made from rubber or elastomer materials that provide both flexibility and structural strength. The integrated design allows optimization of material properties to maintain integrity while reducing weight
3Manufacturing precision
If multiple assembly steps are used, then component precision is ensured, but productivity decreases
Solution Approach 1:
The membrane and orifice upper plate are pre-integrated through vulcanization molding into a single component. This preliminary integration ensures precise positioning and bonding of features before final assembly, eliminating the need for multiple assembly steps and improving productivity

Implementation Method 1
A hydraulic mount for a vehicle may be applied to a bottom surface of an insulator formed of rubber. The engine mount is usually manufactured as a hydraulic mount. The hydraulic mount has a structure in which wide area vibration, such as vibration with low frequency/high amplitude or vibration with high frequency/low amplitude that is input when the engine is driven, may be reduced using viscosity of a fluid
Implementation Method 2
an insulator 30 formed of rubber and integrated with the inner core 20 by a vulcanization molding process

AI summary
Disclosed herein is a hydraulic mount for a vehicle, wherein a serpentine wall that protrudes from a bottom surface of a membrane wherein the membrane operates as a bottom surface of the upper chamber, is bonded to an orifice lower plate and separates a central chamber and a serpentine inertia track. Furthermore, the serpentine inertia track is disposed along a circumference of the central chamber. The hydraulic mount additionally includes a plurality of orifice apertures that are formed in the orifice lower plate and configured to allow communication between the central chamber and the lower chamber.
