Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual connection of pneumatic and electric lines between tractor-trailers requires significant dexterity and force, which is a challenge in achieving automated truck operations.
Innovation Solution
A mechanized gladhand system with a sealing surface, collar, plunger, and turret, along with a retention spring, is used to automate the connection process, assisted by a computer vision system and end effector that identifies and positions the gladhands using cameras, and a mechanized gladhand that reduces torque and structural requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual connection of pneumatic and electric lines is performed, then connection can be made, but significant dexterity and force are required making automation difficult
Solution Approach 1:
The patent replaces manual mechanical operations with an automated end effector system that uses controlled mechanical movement to perform gladhand connections. The end effector mechanically positions and connects the gladhands without requiring human dexterity or force application.
Solution Approach 2:
The patent introduces an end effector as an intermediary device between the operator and the gladhand connection process. This intermediary device performs the actual connection work, eliminating the need for direct human manipulation of the gladhands.
2Strength
If traditional gladhand structure is used, then connection can be made, but high torque and structural demands are required
Solution Approach 1:
The patent modifies the gladhand structure to include dynamic elements such as a plunger that can move axially and a turret that can rotate. These dynamic components allow the connection to be made with reduced torque requirements compared to static traditional gladhand structures.
Solution Approach 2:
The patent divides the gladhand into separate functional components including a collar, plunger, turret, and retention spring. This segmentation allows each component to perform its specific function with optimized structural requirements, reducing overall torque and structural demands.
3Extent of automation
If mechanized gladhand with multiple components is used, then automation is enabled, but device complexity increases
Solution Approach 1:
The patent combines multiple functions into integrated components. For example, the turret serves both as a rotational element for alignment and as a mounting structure for the gladhand connection. The collar integrates retention features and positioning functions, reducing the need for separate components.

AI summary
The present technology describes systems and methods for a mechanized gladhand and an end effector. The mechanized gladhand may have a collar capable of rotational motion while the mating surface may be in contact with a second surface without rotating. This may reduce reaction loads while maintaining the integrity of the connection. The end effector may include a drive motor, clasping tool, and/or driving installed tool that may be used to couple a tool with the gladhand or may be used in other applications. The end effector may have a compact design to allow precise control. The movement of the end effector with the gladhand may be controlled based on image processing to align the tool with another component.
