Independent-Drive Wheel Assembly for Motor Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated guided vehicles (AGVs) equipped with high-power motors experience reduced lifespan due to inadequate vibration absorption when the motor is suspended between a vibration system and the ground, particularly on uneven surfaces, leading to repeated vibrations.
Innovation Solution
A wheeled vehicle with an independent-drive assembly that includes a vibration absorbing element, an auxiliary arm, and a driving member, where the auxiliary arm is designed to pivot or bend relative to the vibration absorbing element, allowing it to absorb vibrations and reduce the impact on the motor, thereby extending its lifespan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the motor is suspended between the vibration system and the ground, then the motor can be positioned for driving, but the motor experiences repeated vibrations that shorten its lifespan
Solution Approach 1:
The drive assembly is divided into independent components: the motor housing, the auxiliary arm, and the vibration absorbing element are separated into distinct functional segments. This allows the motor to be isolated from vibrations while maintaining its driving function, resolving the contradiction between motor positioning and lifespan.
Solution Approach 2:
The vibration absorbing element acts as an intermediary between the motor housing and the auxiliary arm. It absorbs vibrations from the ground before they reach the motor, protecting the motor from repeated vibrations while allowing the motor to remain positioned for effective driving.
2Stability of the object's composition
If the motor is fixed directly to the ground, then the motor remains stable, but vibrations from uneven ground are transmitted directly to the motor
Solution Approach 1:
The vibration absorbing element serves as an intermediary that blocks the transmission path of vibrations from the ground to the motor. It maintains the motor's stable positioning while filtering out harmful vibrations, thus resolving the contradiction between stability and vibration protection.
Solution Approach 2:
The harmful vibration factor is extracted from the system by introducing the vibration absorbing element. This element specifically targets and removes vibrations from the transmission path between the ground and the motor, allowing the motor to remain stable without experiencing the harmful effects of ground vibrations.
3Reliability
If a vibration absorbing element and auxiliary arm are added, then the motor is protected from vibrations, but the device complexity increases
Solution Approach 1:
The vibration absorbing element and auxiliary arm are merged into a unified drive assembly structure that integrates motor mounting, vibration absorption, and wheel support functions. This combined approach provides comprehensive motor protection while minimizing the increase in device complexity through functional integration.
Solution Approach 2:
The auxiliary arm serves multiple functions: it supports the wheel assembly, transmits driving force from the motor, and works with the vibration absorbing element to protect the motor. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while achieving reliable motor protection.
