Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automobile accessories do not provide a portable, adjustable, and supportive step assembly for individuals with difficulty entering vehicles with elevated passenger compartments.
Innovation Solution
A portable automobile step assembly comprising a base with adjustable legs and a handle assembly, designed for temporary use, which includes a friction structure for stability and telescopic, pivotable components for adjustability and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-step accessory is used, then the structure is simple, but it cannot adapt to different vehicle heights or user needs
Solution Approach 1:
The patent applies the dynamics principle by implementing telescopic legs with adjustable length and a foldable base structure. The legs can be extended or retracted to different heights, and the base can be folded for storage or transport. This dynamic configuration allows the step assembly to adapt to various vehicle heights and user requirements while maintaining a relatively simple overall structure when not in use.
2Ease of operation
If a portable step assembly is designed, then it can be easily transported, but it may lack stability and support
Solution Approach 1:
The patent applies segmentation by dividing the step assembly into distinct modular components: a base, multiple telescopic legs, and a handrail assembly. This segmentation allows each component to be independently optimized for its function while maintaining overall portability. The modular structure enables easy assembly and disassembly for transport, yet provides stable support when deployed.
Solution Approach 2:
The dynamic adjustability of the telescopic legs and foldable base allows the structure to transition between a compact portable state for transport and a stable expanded state for use, resolving the contradiction between portability and stability.
3Length of moving object
If the base is positioned close to the ground for portability, then it is easy to store, but it cannot provide sufficient height assistance for elevated vehicle compartments
Solution Approach 1:
The telescopic legs provide dynamic height adjustment, allowing the base to be positioned at different heights depending on the vehicle compartment elevation. When not in use, the legs can be retracted to minimize the overall volume and storage space requirement. This dynamic height adjustment resolves the contradiction between providing sufficient height assistance and maintaining compact storage.

AI summary
A portable automobile step assembly includes a base, a plurality of adjustable legs, and a handle assembly. The base is designed to be temporarily stepped on by a person entering an automobile. The plurality of legs is attached to a bottom surface of the base to support the base a distance from a ground or floor surface. The handle assembly is attached to and extends vertically with respect to a top surface of the base and is designed to be gripped for support by a person stepping on the base.
