Transport Vehicle Holder Sensor for Vertical Distance Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport vehicles cannot accurately monitor the positional relationship between the holder and the article during transfer operations, leading to inefficiencies in handling and potential interference with transfer areas or objects.
Innovation Solution
Incorporating a first sensor that detects the vertical relative distance between the holder and the article's handle contactlessly, along with a second sensor that detects the relative distance via contact, allowing the controller to determine when to hold or release the handle and determine the descending limit, enabling continuous monitoring of the positional relationship.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a flange detection sensor using light blocking is used to detect the container position, then the sensor structure is simple, but it cannot continuously monitor the positional relationship between the holder assembly and the container during transfer operations
Solution Approach 1:
The patent replaces the optical blocking detection method with a non-contact distance sensor that directly measures the vertical distance between the holder assembly and the container. This substitution enables continuous monitoring of the positional relationship during transfer operations, achieving both measurement precision and operational continuity without the limitations of light blocking methods.
2Productivity
If the holder assembly lowers toward the container to receive it, then the transfer operation can proceed, but the existing sensor cannot detect the relative position changes during this dynamic process
Solution Approach 1:
The patent implements a feedback mechanism where the non-contact distance sensor continuously measures the vertical distance between the holder assembly and the container during the lowering and transfer process. This real-time distance information is fed back to the control system, enabling precise control of the transfer operation and preventing loss of positional relationship information throughout the dynamic process.

Function Achieved in This Case
This solution allows for accurate and continuous monitoring of the holder's position relative to the article, ensuring proper handling and preventing interference with transfer areas or objects, thereby enhancing the efficiency and safety of the transfer process.
Implementation Method 1
a first sensor that detects a relative distance in a vertical direction between the holder and the at least one handle contactlessly

AI summary
A transport vehicle includes a first sensor that detects a relative distance in a vertical direction between a holder and at least one handle contactlessly. A controller determines, based on a detection result from the first sensor, whether the relative distance is at a first set value as a reference for the holder to hold or release the at least one handle and whether the relative distance is at a second set value corresponding to a descending limit for the holder with respect to the at least one handle.
