Base Plate Design for AGV Stability and Scanner Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomously guided industrial trucks face challenges in maintaining stability and optimal load distribution due to the use of lithium ion batteries, which reduce the truck's weight and require additional weight to ensure proper wheel pressure and traction. Additionally, existing base plates do not efficiently accommodate scanner units for navigation and personnel protection, particularly when handling pallets in logistics facilities.
Innovation Solution
A base plate design for autonomously guided industrial trucks featuring a central opening for a drive wheel and offset recesses for support wheels, allowing for a low center of gravity and optimal positioning of scanner units. The base plate can be formed as a solid metal part or composed of subunits, providing a massive downward termination for protection and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the base plate is made massive and installed as low as possible, then the center of gravity is lowered and stability is improved, but the weight of the truck increases
Solution Approach 1:
The base plate is designed with non-uniform thickness distribution, being thicker in the central region and thinner at the edges. This local variation in quality provides the necessary mass concentration at the bottom center to lower the center of gravity and improve stability, while reducing overall weight compared to a uniformly massive plate.
2Area of stationary object
If scanner units are arranged at low height above the driving surface, then coverage area is maximized and obstacle detection is improved, but the base plate design becomes more complex
Solution Approach 1:
The base plate is segmented into multiple functional regions with different thicknesses and structural characteristics. The central region accommodates the drive wheel and provides mounting for scanner units at low height, while the edge regions provide structural support and protection. This segmentation allows optimized positioning of scanner units without excessive design complexity.
3Ease of manufacture
If a solid monolithic base plate is used, then manufacturing is simplified, but adaptation to different component arrangements becomes more difficult
Solution Approach 1:
The base plate incorporates locally varied thickness and structural properties that are molded or formed directly into the monolithic structure. This allows different regions to serve different functions (drive wheel accommodation, scanner unit mounting, support wheel placement) while maintaining a single-piece construction that is relatively simple to manufacture.

AI summary
A base plate for an autonomously guided industrial truck having a longitudinal direction and a width direction, the base plate being provided to form a base plate arrangement and to downward delimit a vehicle body of the industrial truck in sections. The base plate comprises a plate body to define, at least in sections, an outline of the base plate arrangement. The base plate comprises an opening central in relation to the width direction and provided for accommodating a drive wheel of the industrial truck. The base plate comprises at least one recess offset in the width direction in relation to a longitudinal center axis for accommodating a support wheel arrangement of the industrial truck.
