Interchangeable Body With Autonomous Lifting And Locking Legs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swap bodies rely on external power sources for lowering and raising, limiting their independence from energy sources and infrastructure, and cannot be permanently supported on the ground without energy consumption.
Innovation Solution
Incorporating a rechargeable energy storage system, such as an accumulator, with a direct current generator and hydraulic lifting device, allowing the swap body to operate independently of external power and maintain support on the ground, along with features like state of charge monitoring, a locking device, and a telematics unit for logistics integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the swap body uses external power sources for lowering and raising, then the lifting device can operate reliably, but the swap body becomes dependent on external infrastructure and cannot operate independently
Solution Approach 1:
The swap body is equipped with its own rechargeable energy storage system (accumulator) and direct current generator, allowing it to independently power the lifting device without relying on external household power connections. The system can charge the accumulator during transport when connected to a truck's power supply, and then autonomously perform lowering and raising operations at the destination.
2Reliability
If the swap body uses hydraulic cylinders with motors for support, then the support function can be maintained, but the system requires continuous energy consumption and cannot be permanently supported on the ground
Solution Approach 1:
The support function is separated into two distinct systems: (1) support legs with locking mechanisms that provide passive, energy-free support when extended to the loading position, and (2) a lifting device with energy storage that provides active lifting capability when needed. This segmentation allows the swap body to be permanently supported on the ground without continuous energy consumption while retaining the ability to be raised when required.
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
Enables the swap body to be lowered and raised independently, ensuring continuous operation without external energy, improved accessibility, and secure logistics operations, with reduced energy consumption and enhanced logistics management.
Implementation Method 1
The lifting device advantageously includes a rechargeable store for electrical energy, which provides the electrical energy required for raising and/or lowering the swap body. Such a storage device, for example in the form of an accumulator
Implementation Method 2
The lift device (8) comprises a hydraulic pump (12), a hydraulic tank (14) and at least one hydraulic cylinder (16)
