Detachable Wheel Platform for Lateral Mobility Vehicle Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobility vehicle platforms are limited to forward and rearward movements, unable to perform leftward and rightward movements, which restricts their versatility and efficiency in various applications.
Innovation Solution
A mobility vehicle platform design featuring a body part with a detachable wheel part that includes a steering member rotatable about an upward/downward axis, allowing the platform to move in multiple directions through a coupling system with protruding members and reinforcing structures, enabling independent rotation of wheel members for leftward/rightward movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional lower platform uses wheel for movement like a general vehicle, then the structure is simple and easy to manufacture, but the platform can only move forwards and rearwards, unable to perform leftward and rightward movements
Solution Approach 1:
The wheel part is divided into independent components: a wheel member for ground contact, a steering member rotatable about a vertical axis to control direction, and a coupling member for detachable connection. This segmentation allows the wheel assembly to perform both forward movement and lateral positioning operations independently
Solution Approach 2:
The steering member is designed to be rotatable about a vertical axis, enabling dynamic adjustment of the wheel member's orientation. This rotational capability transforms the static wheel-vehicle configuration into a dynamic system that can adapt movement direction based on operational requirements
2Adaptability or versatility
If a detachable coupling system is used to enable multi-directional movement, then the versatility is improved, but the coupling structure becomes more complex
Solution Approach 1:
The coupling member serves multiple functions: it provides detachable connection between the wheel part and body part, supports the wheel member structure, and accommodates the steering member rotation. This multi-functionality reduces the need for separate components for each function
3Ease of operation
If the wheel part is made detachable for versatility, then the ease of operation is improved, but the reliability of connection may be reduced
Solution Approach 1:
The coupling member incorporates a curved surface that contacts the protruding member, creating a stable mechanical interface. This curved contact geometry provides natural alignment and stable support while maintaining ease of assembly and disassembly
