Modular AGV Lift Platform With Omega Profile for Ergonomic Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic guided vehicles (AGVs) lack a modular accessory device that can be easily mounted on different types and is adaptable to various production environments and component sizes, complicating loading, unloading, and assembly operations.
Innovation Solution
A modular accessory device with height-adjustable, omega-shaped upper platforms and pantograph lifting units, powered by electric motors, allowing for ergonomic operator interaction and reduced height, along with optional accessories like roller conveyors or revolving tables to facilitate handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional flat upper platform is used, then the structure is simple, but the vertical dimension becomes large and operator ergonomics are poor
Solution Approach 1:
The upper platform is designed with a curved omega shape instead of a flat surface. The central portion is lowered relative to the end portions, creating a U-shaped profile that reduces the maximum vertical dimension while providing ergonomic support for operators at different positions during loading and unloading operations
2Adaptability or versatility
If the accessory device is designed for specific AGV types, then the structure can be optimized, but the adaptability to different AGV types and production environments is reduced
Solution Approach 1:
The accessory device is designed with universal mounting capabilities that allow it to be installed on various AGV types. The lifting units can be positioned at different locations on the upper platform, and the platform itself can accommodate different sizes and shapes of objects, making the device adaptable to multiple production environments without requiring complete redesign
3Adaptability or versatility
If lifting units are positioned only at ends, then the structure is simple, but the ability to handle objects of various sizes and positions is limited
Solution Approach 1:
The lifting units are designed to be movable along the upper platform rather than being fixed at specific locations. This dynamic positioning capability allows the lifting units to be adjusted to optimal positions for handling different objects and configurations, providing versatility without requiring multiple fixed lifting units throughout the structure
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
Enables efficient loading, unloading, and assembly operations in ergonomic positions with reduced height, adaptable to different AGVs and environments, and accommodates various accessories for improved handling capabilities.
Implementation Method 1
said lifting units being operative in a substantially vertical direction by the actuation of at least one first electric motor
Implementation Method 2
the lifting units have a pantograph structure having a base portion arranged to be fixed above the base surface of the AGV, and a vertically movable upper portion
Implementation Method 3
a nut screw mechanism operated by means of a single electric motor which, with a transmission belt, moves the lifting units synchronously in the aforesaid vertical direction

AI summary
An accessory device for use with an automated guided vehicle (AGV) to assist loading and unloading of components onto the AGV for transport by the AGV. In one example, an electric motor, two lifting devices and an inverted omega-shaped upper platform are used to selectively raise and lower the component. In another example an accessory is positioned on a central portion of the upper platform to engage a pallet to further assist loading, unloading and positioning of the pallet relative to the AGV.
