Modular Vehicle Step Structure for Adjustable Length and Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing step designs for vehicles are inconvenient to handle and transport due to their large size and lack of adjustability, leading to high production costs and limited applicability for different vehicle lengths.
Innovation Solution
A step design comprising multiple step segments, a connection step segment, and a fastener that allows for sliding and detachable connections between segments, enabling the step to be adjusted in length and easily disassembled for transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an integral step design is used, then the step structure is simple and strong, but the step is large in length and inconvenient to handle and transport
Solution Approach 1:
The step is divided into multiple detachable segments (first step segment, second step segment, third step segment) connected by connection segments. This segmentation allows the step to be disassembled into smaller parts for convenient handling and transportation, directly resolving the contradiction between structural strength and ease of operation.
2Adaptability or versatility
If an integral step design is used, then the step structure is simple, but the step is not well suited for various applications and different vehicle lengths
Solution Approach 1:
The step is divided into multiple detachable segments (first step segment, second step segment, third step segment) connected by connection segments. This segmentation allows the step to be disassembled into smaller parts for convenient handling and transportation, directly resolving the contradiction between structural strength and ease of operation.
Solution Approach 2:
The connection segments enable dynamic adjustment of the step configuration. The connection segments can be detached and reattached in different configurations, allowing the step to adapt to different vehicle lengths and applications, transforming a static structure into a dynamically adjustable one.
3Volume of moving object
If a retractable step design is used, then the step can be retracted to reduce space, but the structure becomes complex requiring sliding grooves and receiving holes
Solution Approach 1:
The step is divided into multiple detachable segments (first step segment, second step segment, third step segment) connected by connection segments. This segmentation allows the step to be disassembled into smaller parts for convenient handling and transportation, directly resolving the contradiction between structural strength and ease of operation.
Solution Approach 2:
The detachable segments can be nested or stacked together when not in use, reducing the overall volume occupied by the step. This nesting capability allows the step to be compacted into a smaller space without requiring complex sliding grooves or receiving holes.
