Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional goods transportation systems face difficulties in safely and efficiently unloading articles from a loading space to a destination, particularly when space is limited, and using arm-shaped devices is costly and unstable.
Innovation Solution
A transport robot with a door module that opens upward or downward, incorporating a conveyor and a door module with rolling bars and motors to form an unloading slope, allowing safe and space-efficient unloading of articles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a door module is opened upward or downward to enable safe unloading, then unloading safety is improved, but device complexity increases
Solution Approach 1:
The door module integrates multiple functions: it serves as both a protective cover for the unloading opening and a forming element for the unloading slope. The curved surface of the door module directly creates the slope geometry, eliminating the need for separate slope-forming structures and reducing overall device complexity while maintaining safety.
Solution Approach 2:
The door module transitions from a static closed position to dynamic open positions (upward or downward), allowing flexible adaptation to different unloading scenarios. This dynamic capability enables safe unloading while maintaining a compact closed structure, balancing safety requirements with device simplicity.
2Productivity
If the door module forms an unloading slope by opening downward, then unloading efficiency is improved, but space requirements increase
Solution Approach 1:
The door module utilizes vertical dimension by opening upward to create the unloading slope, rather than requiring horizontal space expansion. The curved surface forms the slope in the vertical plane, allowing efficient unloading while maintaining a compact horizontal footprint suitable for narrow spaces.
3Manufacturing precision
If rolling motors and sprockets are added to control door module movement, then operational precision is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical positioning systems with a simplified motor-sprocket mechanism. The rolling motors drive the door module through sprockets that engage with the curved surface, providing precise control through a relatively simple mechanical system that avoids more complex actuators while maintaining positioning accuracy.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The transport robot automatically unloads articles without requiring additional space, preventing overturning or damage, and can operate in narrow spaces, enhancing operational efficiency and safety.
Implementation Method 1
a conveyor that is positioned at a lower portion of the loading area and transfers an article loaded in the loading area to the unloading opening
Implementation Method 2
rolling motors positioned at upper and lower portions of the unloading opening and rotatable, and each sprocket coupled to each rolling motor to rotate
Implementation Method 3
each rolling bar may include a tooth groove defined in a direction of an inner surface of the door module and having a shape corresponding to a shape of the tooth of the sprocket
Implementation Method 4
The door module may form an unloading slope extending from the unloading opening when opened downward

AI summary
This transport robot comprises: a loading area; an unloading opening formed at one side of the loading area; a conveyor which is positioned at the lower portion of the loading area, and which conveys, to the unloading opening, items loaded into the loading area; and a door module for covering the unloading opening, wherein the door module slides upward or downward so as to open the unloading opening, and the transport robot can automatically unload the loaded items and thus can complete transport even in unmanned conditions.
