Arm-Wheel Vehicle Buffering Mechanism for Impact Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing arm-wheel type vehicles face challenges in mitigating impacts from road surfaces, particularly in rotational and length directions, which can lead to inefficient movement and potential damage in rugged or dangerous environments.
Innovation Solution
The arm-wheel type vehicle incorporates a first buffer device on the main body to mitigate rotational impacts and a second buffer device on the arms to absorb length-direction impacts, utilizing elastic members and dampers to absorb and counteract external forces, with a variable actuator for adjustable performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid arm-wheel structure is used, then the vehicle can maintain structural strength, but it cannot effectively mitigate impact forces from road surfaces
Solution Approach 1:
The patent incorporates buffer devices with elastic members (springs) and dampers in advance within the arm structure. These components are pre-configured to absorb and dissipate impact forces before they can damage the rigid structural components, allowing the vehicle to maintain both strength and impact resistance.
2Object-affected harmful factors
If buffer devices are added to mitigate impact, then impact resistance improves, but device complexity increases
Solution Approach 1:
The patent uses flexible elastic members (springs) and dampers integrated into the arm structure. These flexible components provide impact mitigation through their inherent mechanical properties rather than complex active control systems, reducing overall device complexity while maintaining effective shock absorption.
3Object-affected harmful factors
If the arm structure is made more complex to absorb impacts, then impact mitigation improves, but the vehicle's mobility and speed are reduced
Solution Approach 1:
The patent employs dynamic buffer devices with elastic members and dampers that actively respond to impact forces. These components dynamically adjust their resistance based on the magnitude and direction of applied forces, allowing the arm to remain relatively light and responsive during normal movement while providing robust protection during impact events.
