Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tank container transport vehicles face inefficiencies in unloading processes, particularly when there is a small amount of liquid remaining, leading to reduced unloading speed and incomplete unloading, especially when handling hazardous chemicals, due to the unwieldy structure and high structural strength requirements of current assistant unloading devices.
Innovation Solution
A trailer and frame design incorporating an air bag-based assistant unloading device with a guiding tube and rod system, stopper for height limitation, and reinforcing structures, allowing for efficient and stable lifting of tank containers with a simple and lightweight configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a hydraulic oil cylinder is used as an assistant unloading device, then lifting capability and lifting height are improved, but device complexity and structural strength requirements increase
Solution Approach 1:
The patent uses an air bag (pneumatic device) instead of a hydraulic oil cylinder to achieve lifting function. The air bag is installed at the front bolster of the frame, and when inflated, it lifts the tank container front end. This pneumatic solution maintains sufficient lifting capability while significantly simplifying the device structure and reducing installation complexity compared to hydraulic systems.
Solution Approach 2:
The air bag itself is a flexible shell structure that can expand and contract to provide lifting force. This flexible membrane approach replaces rigid hydraulic components, reducing device complexity while maintaining the necessary lifting function for unloading operations.
2Force
If a hydraulic oil cylinder is used as an assistant unloading device, then lifting capability is improved, but ease of operation deteriorates due to unwieldy structure
Solution Approach 1:
The air bag system requires only air supply for operation, eliminating the need for hydraulic fluid management, pressure regulation, and complex control systems. The operator simply needs to control the air inflation, making the device much easier to operate despite maintaining adequate lifting capability for unloading tank containers.
3Stability of the object's composition
If guiding structures are added to constrain air bag movement, then stability is improved, but device complexity increases
Solution Approach 1:
The guiding rods provide mechanical feedback by physically constraining the air bag's movement path. As the air bag inflates and lifts the load, the guiding rods ensure vertical movement only, automatically stabilizing the system without requiring complex control mechanisms or additional stabilization devices.
Solution Approach 2:
The guiding rods act as intermediary elements between the air bag and the frame structure. These simple rod components mediate the force transmission and movement control, providing necessary stability while adding minimal structural complexity to the overall system.
