Universal Joint Member for Adjustable Vehicle Chassis

Solution Overview

Problem

Conventional vehicle production methods face challenges in small quantity batch production, particularly for electric and working vehicles, due to increased production costs and decreased efficiency from using mixed components, necessitating a method to manufacture chassis of various sizes using the same components.

Innovation Solution

A joint member for coupling a chassis frame with multiple insertion grooves of varying depths and positions, allowing the length and width of the chassis to be adjusted by positioning frames, enabling the production of vehicles with different sizes and shapes using the same components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If components of different sizes are separately manufactured and managed for each vehicle model, then chassis size requirements are met, but production costs increase and production efficiency decreases

Engineering Contradiction:

Improvechassis size variationVSAvoidproduction efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The joint member is designed with multiple insertion grooves at different positions and depths, allowing a single component to serve multiple chassis size configurations.
