Distribution Facility Side-On Parking Transfer Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional distribution facilities face challenges in improving the operation efficiency of transport vehicles that need to park side-on, as it is difficult to park these vehicles with high positional accuracy, leading to decreased efficiency due to the need to manage gaps and avoid other vehicles while loading and unloading.
Innovation Solution
A distribution facility design featuring a platform with a first and second transport portion and a transfer device that moves back and forth in the vehicle's widthwise direction, allowing the transfer device to be closer to the load bed of a parked transport vehicle, enabling side-on parking and efficient loading/unloading operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a transport vehicle parks side-on on the berth, then loading and unloading operations can be performed efficiently, but it becomes difficult to achieve high positional accuracy and maintain parallel alignment with the platform edge
Solution Approach 1:
A gap filling device is introduced as an intermediary component between the transport vehicle and the platform. This device automatically fills the gap formed when the vehicle parks side-on, enabling the vehicle to park without achieving perfect parallel alignment while still maintaining efficient loading and unloading operations. The mediator absorbs the positional inaccuracy and maintains the functional connection.
Solution Approach 2:
The gap filling device is designed to be movable and adjustable, capable of adapting to different parking positions and gap sizes. This dynamic characteristic allows the system to accommodate variations in parking accuracy while maintaining optimal loading and unloading efficiency, resolving the contradiction between operational efficiency and positioning precision.
2Manufacturing precision
If the driver carefully adjusts the vehicle position to minimize gaps and avoid other vehicles, then parking positional accuracy improves, but the time required for parking increases
Solution Approach 1:
The gap filling device operates automatically to correct parking position deviations without requiring additional manual intervention from the driver. The system self-adjusts to compensate for gaps and misalignments, eliminating the need for the driver to spend extra time carefully positioning the vehicle while maintaining good parking accuracy.
Solution Approach 2:
The gap filling device is positioned and configured in advance to anticipate and compensate for typical parking deviations. By preparing the gap filling mechanism beforehand, the system can quickly correct positioning errors as the vehicle arrives, reducing the overall parking time while maintaining accuracy.
3Productivity
If the vehicle parks closer to the platform edge to improve loading efficiency, then the gap for article transfer decreases, but the risk of collision with other vehicles increases
Solution Approach 1:
The gap filling device serves as a protective intermediary that allows the vehicle to park closer to the platform edge for improved loading efficiency. The device compensates for the reduced safety margin by automatically managing the gap between the vehicle and platform, eliminating the need for excessive clearance while preventing collision hazards.
