Solution Overview

Problem

Conventional vehicle lift kits require a separable frame to increase vehicle height, which is not suitable for vehicles with unibody construction, limiting the ability to raise the body relative to the suspension system effectively.

Innovation Solution

A vehicle suspension extension apparatus with an extension framework of rigid metallic materials, featuring mounting holes aligned with suspension and body mounting features, and coated with protective and decorative materials, allows for increased vehicle height by interposing between the suspension and unibody structure without compromising structural rigidity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of stationary object

If conventional lift kits are used to increase vehicle height, then vehicle body height is improved, but the solution is not suitable for unibody construction vehicles

Engineering Contradiction:

Improvevehicle body heightVSAvoidcompatibility with unibody construction

Core Design Contradiction:

Length of stationary objectVSAdaptability or versatility

Solution Approach 1:

The patent introduces an extension framework as an intermediary component that connects between the unibody and the suspension system. This framework includes mounting plates with alignment features that interface with both the unibody mounting features and the suspension mounting features, enabling height adjustment without requiring a separable frame structure.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The extension framework is divided into multiple components including mounting plates, extension members, and fastening mechanisms. The mounting plates are separate from both the unibody and suspension, allowing independent installation and adjustment. This segmentation enables the system to work with unibody construction by creating discrete mounting interfaces.

Inventive Principle:

Principle #1Segmentation

2Length of stationary object

If extension framework is added to increase vehicle height, then suspension travel is improved, but structural rigidity may be compromised

Engineering Contradiction:

Improvevehicle heightVSAvoidstructural rigidity

Core Design Contradiction:

Length of stationary objectVSStrength

Solution Approach 1:

The extension framework utilizes composite construction combining rigid metallic materials for structural members with protective coatings for surface protection. The mounting plates and extension members are made from materials that provide both strength and rigidity, while the protective coating layer adds corrosion resistance without significantly affecting structural properties.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The extension framework employs curved or angled mounting surfaces and reinforced corner designs that distribute stress more effectively. The mounting plates feature curved reinforcement patterns and the extension members use optimized geometric shapes that enhance rigidity while maintaining the height extension function.

Inventive Principle:

Principle #14Spheroidality (Curvature)
