Solution Overview
Problem
Automated guided vehicles (AGVs) face challenges in navigating narrow spaces due to fixed driving wheel heights, which restrict their versatility and efficiency in vehicle manufacturing processes.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the driving wheel height is fixed, then the AGV structure is simple, but the AGV cannot operate in narrow spaces
Solution Approach 1:
The patent applies the dynamics principle by making the driving wheel height adjustable rather than fixed. The actuator mechanism allows the driving wheel to move vertically between a first height (for narrow space operation) and a second height (for stable driving), transforming a static structure into a dynamic one that can adapt to different operational requirements.
Solution Approach 2:
The patent segments the AGV structure into a first portion (containing the driving wheel and actuator) and a second portion (main body). This segmentation allows the first portion to be independently adjusted in height while the second portion remains stable, enabling the AGV to navigate narrow spaces without compromising overall structural integrity.
2Adaptability or versatility
If the driving wheel is lifted off the ground, then the AGV can navigate narrow spaces, but the driving motor requires more power
Solution Approach 1:
The patent applies partial action by lifting only the first portion of the AGV (containing the driving wheel) rather than the entire vehicle. The actuator selectively raises the driving wheel to a first height only when narrow space navigation is required, while the second portion remains at a lower, more energy-efficient position. This partial elevation reduces the overall power consumption compared to lifting the entire AGV.
3Adaptability or versatility
If the driving wheel height is adjustable, then the AGV can operate in various spaces, but the device complexity increases
Solution Approach 1:
The patent replaces complex multi-component mechanical lifting systems with a simplified actuator mechanism directly connected to the driving wheel. This actuator integrates the lifting function into a compact design that reduces the number of mechanical parts while maintaining the ability to adjust the driving wheel height between first and second positions.
Solution Approach 2:
The patent merges the actuator and driving wheel into an integrated first portion of the AGV. This combination allows the height adjustment mechanism to be closely coupled with the driving wheel, reducing the overall space required for the mechanism and simplifying the structural design while maintaining operational flexibility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution reduces the capacity and power consumption of the driving motor, minimizes space requirements, and enhances the AGV's ability to operate in narrow spaces by allowing the driving wheel to be separated from the ground, thereby improving operational efficiency and flexibility.
Implementation Method 1
A cam may be formed at the cam shaft and may come into contact with the bearing based on rotation of the cam shaft
Implementation Method 2
an elastic member provided to allow the driving wheel to be tightly attached to a ground

AI summary
An automated guided vehicle is provided and includes a frame in which a driving wheel is accommodated and an actuator that is connected to lift and lower a first portion of the frame centered around a hinge part formed at a second portion of the frame. Only one side of the frame is lifted to lift the driving wheel from the floor, thus reducing capacity and power consumption of the driving motor, and a region for space utilization is increased by reducing a size by applying the driving motor.
