Solution Overview
Problem
Commercial ground operations such as airports and warehouses face challenges like limited apron space, manpower shortages, and operational disruptions, with existing digital technologies and manual handling methods being inefficient and prone to disruptions.
Innovation Solution
The development of robotic systems equipped with end-of-arm tool (EOAT) assemblies and conveyer systems that include mechanized tool subassemblies with holding members and lifting members to efficiently manage and transport objects, such as baggage, by providing coordinated lateral movement and lifting capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If suction methods are used to pick up and move objects, then some manpower relief is achieved, but the system is susceptible to disruptions such as inclement weather and does not save significant manpower
Solution Approach 1:
The patent replaces suction methods (fluid-based) with a robotic system using end effectors that directly grasp and manipulate objects mechanically. The robotic arm with specialized end effectors provides reliable object handling that is not susceptible to weather disruptions affecting suction efficiency
Solution Approach 2:
The robotic system performs object handling operations autonomously without requiring significant human intervention. The system self-regulates through sensors and control systems to adapt to different object types and conditions, providing consistent performance regardless of environmental factors
2Productivity
If rollers and conveyor belts are used to provide lateral movement of objects, then some manpower relief is achieved, but significant manpower is still required for loading and unloading objects
Solution Approach 1:
The robotic system performs multiple functions including approaching objects from various directions, grasping objects of different sizes and shapes, lifting them vertically, and positioning them precisely. This multi-functional capability eliminates the need for separate manual operations for loading and unloading that would be required with simple conveyor systems
Solution Approach 2:
The robotic arm operates in three-dimensional space, allowing it to approach objects from any direction and manipulate them vertically and laterally. This dimensional freedom enables the system to handle objects in ways that conventional two-dimensional conveyor systems cannot, reducing the need for manual intervention in loading and unloading
3Productivity
If digital technology is used to improve efficiency and performance, then communication and oversight are improved, but the technology is more susceptible to disruptions such as inclement weather
Solution Approach 1:
The patent replaces digital/electronic systems with a mechanical robotic system for physical object handling. While digital technology may be used for control and coordination, the core object manipulation function is performed mechanically, which is inherently more reliable in adverse weather conditions compared to electronic systems

AI summary
An end of arm tool (EOAT) assembly can include a tool base subassembly having a tool base attachment surface as well as a first and second mechanized tool subassembly, each being movably attached to the tool base subassembly along the tool base attachment surface. The mechanized tool subassemblies include an elongated body oriented orthogonally relative to the tool base attachment surface, and a holding member attached to its respective elongated body. The holding members can have an engaged position to pass beneath an object to assist with lifting of the object and a disengaged position that does not contribute to lifting of the object. Movement of the first and second mechanized tool assemblies along the tool base attachment surface can provide for opening and partially closing of a gap there between to laterally provide space for engaging with the object followed by squeezing the object for lifting.
