Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tank lifting and handling devices lack stability, ease of maintenance, and versatility in handling tanks of various configurations, particularly when moving between different elevations, and often require multiple operators or complex mechanisms.
Innovation Solution
A portable tank lifting and handling apparatus featuring a U-shaped transport carriage with a vertical beam, reinforcement cross members, and a parallel swing assembly that includes a drive mechanism for lifting and lowering tanks, along with a tank retaining bracket and sliding engagement mechanism for secure positioning, allowing single-person operation and stability through a wheeled carriage with locking plates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If complex mechanisms are used for tank lifting and handling, then lifting capability and versatility are improved, but device complexity and maintenance needs increase
Solution Approach 1:
The device is divided into modular components: a U-shaped transport frame with parallel swing assemblies that can be independently adjusted, a tank retaining bracket with movable securement mechanisms, and a drive mechanism. This segmentation allows each component to perform its specific function while maintaining overall system versatility for handling tanks of various configurations.
Solution Approach 2:
The parallel swing assemblies are designed to move between extended and retracted positions to adapt to different tank elevations. The tank retaining bracket includes movable securement mechanisms that can adjust their position dynamically. This dynamic capability provides versatility for handling tanks of various configurations without requiring multiple fixed mechanisms.
2Ease of operation
If portable design is implemented for easy transport, then ease of operation and portability are improved, but structural strength and stability may be compromised
Solution Approach 1:
The transport frame is designed as a portable U-shaped structure that can be assembled and disassembled. The parallel swing assemblies are separately attachable components that can be secured to the frame. This segmented design allows the device to be easily transported and stored while maintaining structural integrity when assembled for tank handling operations.
Solution Approach 2:
The parallel swing assemblies include pre-configured securement mechanisms and attachment points that are prepared in advance. The tank retaining bracket is designed with pre-positioned securement mechanisms that can quickly engage with the tank. This preliminary preparation ensures that when the device is assembled, it immediately provides the necessary structural strength and stability for safe tank handling.
3Reliability
If securement mechanisms are added to ensure tank stability, then reliability and safety are improved, but device complexity increases
Solution Approach 1:
The tank retaining bracket integrates multiple securement functions into a single component assembly. The upper and lower securement mechanisms are combined with the bracket structure itself, eliminating the need for separate attachment devices. This merging approach ensures reliable tank securement while avoiding the complexity of multiple independent mechanisms.
Solution Approach 2:
The securement mechanisms are designed to move between engaged and disengaged positions dynamically. The movable securement mechanisms can automatically adjust to accommodate tanks of various configurations while maintaining reliable securement. This dynamic capability provides high reliability without requiring complex adjustable mechanisms for each tank type.
