Polymer Valve Block Assembly for Lightweight AMT Transmission Actuation

The patent applies composite materials by combining glass-fibre reinforcement with thermoplastic polymer matrix to create a valve block that achieves metal-like strength while significantly reducing weight. The glass-fibre reinforcement provides structural strength and rigidity, while the polymer matrix binds the fibres and provides the base material properties, creating a lightweight yet durable composite structure suitable for automotive applications.

The patent changes the material parameters by transitioning from dense metal materials to polymer-composite materials with different density, strength-to-weight ratio, and manufacturing characteristics. This parameter change enables achieving comparable mechanical strength with significantly reduced weight, addressing the contradiction between strength and weight requirements.

The use of composite materials with glass-fibre reinforcement in thermoplastic polymers provides enhanced durability and service life while enabling simpler manufacturing processes. The composite structure offers improved mechanical properties comparable to metal, but with the advantage of being processable through injection molding, reducing manufacturing complexity.

The patent substitutes traditional mechanical manufacturing processes (such as machining, drilling, and assembling metal components) with injection molding technology for composite materials. This substitution simplifies the manufacturing process by enabling near-net-shape production, reducing the number of manufacturing steps, and eliminating complex post-processing operations while maintaining structural integrity and service life.

The patent employs composite materials consisting of glass-fibre reinforcement in a thermoplastic polymer matrix to achieve structural strength comparable to metal at lower material cost. The glass-fibre provides reinforcement and strength, while the polymer matrix provides the base structure, creating a cost-effective composite that meets structural requirements without the high material costs associated with metal components.

The patent changes material parameters by selecting polymer-composite materials with optimized strength-to-cost ratio. This parameter change enables achieving the required structural strength at lower material cost compared to metal-based solutions, while the injection molding process further reduces manufacturing costs through high-volume production capability and reduced material waste.
