Multi-Wheel Vehicle With Adjustable Suspension For Obstacle Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cars with four wheels have limited movement capabilities, as they can only turn by changing wheel direction or reverse, restricting their variety of movements.
Innovation Solution
A car design featuring at least eight pairs of rotatable wheels and supporting members with adjustable distance and position, utilizing a turning portion with a parallel link mechanism to enable various movements, including forward run, rotation, and navigation over obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional four-wheel car design is used, then the structure is simple, but the variety of movements is limited
Solution Approach 1:
The car body is divided into multiple independent wheel units (at least eight pairs of wheels and supporting members) that can operate independently. Each wheel assembly can be controlled separately to achieve diverse movement patterns including forward motion, rotation, and obstacle navigation, thereby increasing versatility without requiring a completely new monolithic structure
Solution Approach 2:
The supporting members are designed with dynamic adjustment capabilities, allowing the distance between wheels and the bottom portion to be changed, and enabling position adjustment of wheels through rotatable turning portions. This dynamic configurability allows the same structure to adapt to different movement requirements and terrain conditions
2Adaptability or versatility
If multiple wheels with adjustable positions are provided, then various movements are enabled, but the device complexity increases
Solution Approach 1:
Each supporting member is designed as a universal module that can perform multiple functions: supporting wheel rotation, adjusting wheel direction, changing wheel position relative to the bottom portion, and navigating obstacles. This multi-functionality reduces the need for separate specialized components for each function, thereby managing complexity while enhancing capability
Solution Approach 2:
The supporting member structure employs a nested arrangement where the first supporting portion supports the wheel, the second supporting portion supports the first supporting portion, and the turning portion supports the second supporting portion. This nested hierarchy organizes complexity in a structured manner, allowing each subsystem to be managed independently while contributing to the overall versatile movement capability

AI summary
A car includes a car body having a bottom portion, a wheel that is rotatable, and a supporting member for supporting the wheel, the supporting member being provided to the bottom portion. At least eight pairs of the wheel and the supporting member are provided. The supporting member has a first supporting portion for supporting the wheel rotatably, a second supporting portion for supporting the first supporting portion so that a direction of the wheel supported by the first supporting portion can be changed, and a turning portion that is rotatable about a rotation axis with its axial direction along a direction orthogonal to the bottom portion, the turning portion being provided to the bottom portion. The turning portion supports the second supporting portion so that a distance between the wheel and the bottom portion can be changed, and a position of the wheel can be moved by a rotation of the turning portion in a state that the distance is maintained.
