Self-balancing Vehicle Battery Integration in Rotating Joint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-balancing vehicles have a complex three-layer structure with an aluminum die-casting part, leading to high costs and low space utilization, due to additional process steps and separate installation of power supply and rotating components.
Innovation Solution
A self-balancing vehicle design featuring an upper case and lower case connected by a rotating connection member, with the battery installed inside and the controller on the upper case, eliminating the aluminum structure, simplifying the structure, improving space utilization, and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a three-layer structure with aluminum die-casting part is used, then structural strength is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the aluminum die-casting part with the surface case into a single integrated shell structure. The shell includes a shell body and shell cover that enclose the balancing mechanism, eliminating the need for separate aluminum structural components while maintaining structural integrity and reducing assembly complexity.
Solution Approach 2:
The shell structure serves multiple functions: it provides structural support, encloses the balancing mechanism, and integrates the power supply housing. This multi-functional design replaces the specialized aluminum die-casting part, reducing the number of components while maintaining structural strength.
2Ease of operation
If power supply and rotating connection member are installed separately, then installation flexibility is improved, but space utilization deteriorates
Solution Approach 1:
The power supply is nested within the rotating connection member, which itself is part of the shell assembly. This nested arrangement allows the power supply to occupy the internal space of the rotating connection member, maximizing space utilization while maintaining installation flexibility through modular assembly.
Solution Approach 2:
The patent utilizes the vertical dimension within the rotating connection member to house the power supply, transforming a potential waste of internal volume into productive space utilization. This dimensional approach allows compact arrangement of components without compromising installation flexibility.
