Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual handling is used for cargo loading and unloading, then labor flexibility is maintained, but loading and unloading efficiency is low
Solution Approach 1:
The platform is designed to be dynamically adjustable in height, transitioning between a lowered position for ground-level operations and a raised position aligned with the carriage floor. This dynamic positioning enables automated cargo handling mechanisms to operate efficiently while maintaining flexibility for different operational modes
Solution Approach 2:
The movable platform serves as an intermediary between the ground and the carriage, providing a transition surface that enables automated cargo carrying mechanisms to transfer cargo efficiently. The platform mediates the height difference and facilitates automated handling operations
2Productivity
If a fixed platform height is used, then structural simplicity is maintained, but forklift operations require frequent raising and lowering, creating safety problems and reducing efficiency
Solution Approach 1:
The platform height is made dynamically adjustable through lifting oil cylinders, allowing it to be positioned at ground level for stable forklift operations and then raised to the carriage floor level for cargo loading. This eliminates the need for frequent height changes during operations
Solution Approach 2:
The platform is preliminarily positioned at ground level before cargo operations begin, providing a stable base for forklift operations. This preliminary positioning ensures safety during ground operations before the platform is raised for the actual loading process
3Productivity
If large cranes are used for loading and unloading large cargo, then cargo handling capability is improved, but loading and unloading cost is increased
Solution Approach 1:
The cargo handling system is segmented into modular components including the movable platform, cargo carrying mechanisms, and lifting cylinders. This segmentation allows the system to handle large cargo effectively while using smaller, more cost-effective equipment compared to large cranes
Solution Approach 2:
The movable platform system serves multiple functions: it acts as a support surface for forklift operations, a platform for automated cargo carrying mechanisms, and a height-adjustable interface for different cargo sizes. This multi-functionality replaces the need for specialized heavy equipment like large cranes
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 device significantly improves cargo loading and unloading efficiency, reduces labor costs, and enhances safety by minimizing the need for frequent forklift operations and reducing the overall working height.
Implementation Method 1
lifting oil cylinders drive the cargo carrying platform to move up and down, so that the supporting platform is flush with an upper surface of the upper cover or the supporting platform is lower than the upper surface of the upper cover

AI summary
The present disclosure relates to the technical field of cargo loading and unloading, and discloses a lifting type carriage cargo loading and unloading device. The lifting type carriage cargo loading and unloading device includes a frame, a cargo carrying mechanism and a power mechanism. The frame includes a cargo carrying platform, lifting oil cylinders and a supporting platform. The lifting oil cylinders are connected to both sides of the cargo carrying platform. The supporting platform is arranged on an upper surface of the cargo carrying platform. The supporting platform is provided with support columns. The support columns are slidably penetrated into the cargo carrying platform and extend beyond a lower surface of the cargo carrying platform. The cargo carrying mechanism is movably installed on the cargo carrying platform and includes a push-and-pull assembly and at least two cargo carrying assemblies. Each cargo carrying assembly is provided with a liftable upper cover. The push-and-pull assembly is used for driving the upper cover to rise or restoring the upper cover. The power mechanism is installed on the cargo carrying platform and connected with the cargo carrying mechanism. The lifting oil cylinders drive the cargo carrying platform to move up and down, so that the supporting platform is flush with an upper surface of the upper cover or the supporting platform is lower than the upper surface of the upper cover. The disclosure can realize one-time loading and unloading without manual handling. During loading and unloading cargo, the cargo carrying platform is placed on the ground, and a forklift needs not to be lifted frequently, reducing working strength and improving the loading and unloading efficiency.
