Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load transport systems face challenges in efficiently moving and repositioning heavy loads due to the need for disassembly, frequent maintenance, and potential material weakening when removing hydraulic lift components, particularly in harsh environmental conditions like those found in oil rigs.
Innovation Solution
A removable axle assembly with a tapered surface and clamping structure that allows for secure attachment and detachment from an axle mount, using fastening devices to exert a compression force, enabling easy maintenance and repositioning without material damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the lift cylinder rod is welded directly to the axle assembly to provide a rigid connection, then the connection strength and stability are improved, but the ease of repair and maintenance deteriorates because the entire assembly must be removed and replaced when the rod fails
Solution Approach 1:
The axle assembly is divided into separable components: the axle body and the lift cylinder rod, connected through a mounting structure with interface features (tapered surface, alignment features, fastening devices). This segmentation allows the rod to be replaced independently without removing the entire axle assembly, resolving the contradiction between strong connection and ease of repair.
2Stability of the object's composition
If the axle assembly is made permanently fixed to ensure stability during heavy load transport, then the reliability under load is improved, but the ease of operation deteriorates because repositioning requires disassembly and reassembly
Solution Approach 1:
The connection between the lift cylinder rod and axle assembly transitions from a static permanent weld to a dynamic removable connection. The mounting structure allows the assembly to be firmly secured during operation (providing stability) yet easily detached when repositioning is needed, resolving the contradiction between stability and operational flexibility.
3Reliability
If the lift cylinder rod is removed and replaced frequently for maintenance, then the reliability is improved by replacing failed components, but the loss of time increases due to the complex removal and reinstallation process
Solution Approach 1:
The mounting structure is designed in advance with preliminary features including tapered surfaces for easy alignment, predefined fastening device locations, and clamping structures that guide the assembly process. These preliminary design elements enable rapid installation and removal of the lift cylinder rod, reducing maintenance time while maintaining system reliability.
4Ease of repair
If torch cutting is used to remove the lift cylinder rod from the weldment, then the ease of repair is improved by enabling on-site maintenance, but the strength of the remaining components deteriorates due to material weakening from the cutting process
Solution Approach 1:
The design extracts the connection method from permanent welding to a removable mechanical interface. The tapered surface and fastening devices allow the lift cylinder rod to be removed without thermal cutting, eliminating the harmful effects of torch cutting on the metal plates and weldment while still enabling on-site maintenance by simply unfastening the mounting structure.

Implementation Method 1
the clamping structure may be configured to exert a compression force that maintains contact between the tapered surface of the frame support structure and the inner surface of the axle mounting structure
Implementation Method 2
The axle mounting structure may include an inner surface that aligns with a tapered surface of the axle mount
