Transfer Cart Deck Angle and Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transfer cart designs face inefficiencies due to variable operation pause times and difficulty in covering the front and back of the cart during movement, especially on tracks with varying gradients, leading to redundant space usage and interference with stationary components.
Innovation Solution
A transfer cart with a moving-direction operation deck that adjusts angle and height according to the track's curvature, using a bendable frame and variable height mechanism, allowing operation decks to be positioned on both sides and avoiding redundant space usage, without the need for a drive power source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If operation decks are moved in sync with the transfer cart, then operation can be performed during transfer, but it is difficult to cover front and back of the transfer cart in the moving direction
Solution Approach 1:
The operation deck is made dynamically adjustable in position along the moving direction rather than being fixed or moving strictly in sync with the transfer cart. This allows the operation deck to be positioned flexibly to cover front and back spaces while adapting to different operational needs and track configurations.
2Ease of operation
If operation decks are provided only at front and back of the transfer cart, then operation coverage is improved, but a redundant transfer space is created inevitably on tracks with varying gradient
Solution Approach 1:
The operation deck's position is dynamically adjustable rather than fixed at front and back. This allows the deck to be repositioned to minimize space occupation when not in use, eliminating redundant transfer space while maintaining operational coverage when needed.
Solution Approach 2:
The position parameter of the operation deck is made variable along the moving direction. By changing the position parameter dynamically, the system optimizes both operation coverage and space utilization, avoiding the creation of redundant transfer space on tracks with varying gradients.
3Ease of operation
If the transfer is paused for operation, then operation can be performed on the body, but efficiency deteriorates because pause period varies depending on operation
Solution Approach 1:
The operation deck is made movable relative to the transfer cart, allowing it to dynamically adjust its position and speed independently. This enables continuous transfer operation while providing operational capability, eliminating the need for pauses and maintaining high productivity.

AI summary
Provided is a transfer cart that that has a simple structure, facilitates operation in front and back spaces of a moving direction, and does not take up a redundant transfer space in a locations where operation is not performed. The transfer cart includes a running frame, a main carrier capable of carrying thereon an object to be transferred, and moving-direction operation decks disposed at front and back of the moving direction on the main carrier and running frame. The moving-direction operation decks are configured to change angle with the main carrier in accordance with the radius of curvature of a track, and configured to have a variable height mechanism to be able to change height thereof in the up and down direction.
