Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for lifting and transporting massive containers, such as nuclear waste casks, are inefficient due to high profiles and lack of compactness, making them difficult to move and position safely.
Innovation Solution
A device comprising a base frame assembly, a cradle pivotally connected to the base frame, and hydraulic cylinders for vertical movement and rotation, allowing for the lifting, rotation, and repositioning of massive containers in a compact and controlled manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing methods are used for lifting and transporting massive containers, then the containers can be moved, but the device has a high profile and lacks compactness making it difficult to move and position safely
Solution Approach 1:
The patent transitions from vertical stacking (high profile) to horizontal arrangement (low profile). The cradle and container remain horizontal during transport, and the lifting mechanism operates horizontally rather than vertically, reducing the device's profile height while maintaining all necessary functions.
Solution Approach 2:
The patent employs dynamic, adjustable components including telescopic support legs that can extend and retract, and a cradle that can pivot between horizontal and vertical positions. This allows the device to adapt its profile height based on operational needs versus transport requirements.
2Volume of moving object
If existing lifting devices are used, then containers can be lifted, but the devices are not compact and have large footprints
Solution Approach 1:
The patent implements nesting by placing the cradle within the base frame assembly, and positioning the container within the cradle. The support legs nest within the base frame when retracted, creating a compact hierarchical structure that maintains large lifting capacity while minimizing overall device volume.
Solution Approach 2:
The patent redistributes the device volume by expanding horizontally rather than vertically. The base frame assembly provides a wide but low footprint, accommodating all lifting and rotation mechanisms within this expanded horizontal dimension while keeping the profile height minimal.
3Reliability
If massive containers are moved using traditional methods, then transport is possible, but safety and operational efficiency are reduced
Solution Approach 1:
The patent creates a multi-functional device that can lift, rotate, and position containers in various orientations (horizontal and vertical) using a single integrated system. The hydraulic cylinder and pivot mechanism enable the same base frame and cradle assembly to perform multiple operations, improving both safety through consistent design and efficiency through reduced setup time.
Solution Approach 2:
The patent introduces a cradle as an intermediary component between the base frame and the container. This cradle serves as a mediator that facilitates safe and controlled transfer of the container, enabling rotation and positioning operations while protecting both the container and the lifting mechanism.
