Hinged Gantry for Vehicle Washing Machine Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for assembling washing machines for vehicles are hazardous and costly, particularly for large industrial vehicles, as they require lifting heavy structures with machinery that poses risks to workers and involves excessive hydraulic system investments for portable structures.
Innovation Solution
A system using a gantry structure with a crossbar and hinged pillars that are connected on the ground, allowing the pillars to rotate and secure to the crossbar using a fixing system, which can be lifted by a forklift truck without additional costs, ensuring stability and safety across various machine sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the structure is assembled at height using lifting machinery, then the machine can be assembled in its working position, but the safety risk to workers increases significantly
Solution Approach 1:
The patent applies preliminary action by assembling the pillars and crossbar on the ground in a horizontal position before lifting. The hinged connection allows the structure to be prepared safely at ground level, then the entire assembled structure is lifted as one unit to the working position, eliminating the danger of working at height during assembly
Solution Approach 2:
The patent inverts the traditional assembly approach by assembling the structure horizontally on the ground first, then lifting it to the vertical working position. This reverses the conventional method of assembling at height, thereby eliminating the safety hazard while maintaining assembly feasibility
2Adaptability or versatility
If hydraulic actuators are used to unfold and erect the gantry, then the structure can be assembled and disassembled portably, but the investment cost increases significantly
Solution Approach 1:
The patent extracts the complex hydraulic system from the assembly process. Instead of using hydraulic actuators to unfold and erect the gantry, the invention uses simple hinged connections that allow manual assembly on the ground, thereby eliminating the need for expensive hydraulic equipment while maintaining portability
Solution Approach 2:
The patent replaces expensive hydraulic systems with simple, inexpensive hinged connections and manual assembly methods. The hinged joints are simple mechanical elements that can be assembled and disassembled without costly equipment, making the system portable but eliminating the need for expensive hydraulic infrastructure
3Reliability
If the machine is assembled horizontally and then lifted, then the assembly is safer, but the structure must be turned to working position which introduces toppling risk
Solution Approach 1:
The patent merges the assembly and lifting operations into a single integrated process. The structure is assembled horizontally with hinged connections, then the entire assembled unit is lifted and rotates as one stable structure to the vertical working position. The hinged connections are designed to maintain structural integrity throughout this transformation, eliminating the toppling risk that would occur if components were manipulated separately at height
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
The system simplifies the assembly process, reduces safety risks, and eliminates the need for costly hydraulic systems, enabling secure and cost-effective assembly of washing machines for both industrial and utility vehicles.
Implementation Method 1
By means of the force of gravity, the pillars rotate on the hinged means around the crossbar, gradually losing their initial horizontal position.

AI summary
The system includes a structure including a crossbar and a series of pillars connected to the crossbar by hinged joining means, and a fixing system to secure each pillar to the crossbar, where the hinged joining means are configured to operate as the crossbar is lifted from the ground, causing the pillars to be lifted to a final position in which the fixing systems secure the pillars to the crossbar in a stable position.
