Solution Overview
Problem
Existing mobile hydraulic cooling assemblies for trucks are inefficient in cooling hydraulic fluid due to suboptimal design, leading to potential overheating issues, as they do not effectively utilize space and strain on fittings can cause leaks.
Innovation Solution
A slim mobile hydraulic cooling assembly with a reservoir having offset interior surfaces and an angled air chamber, along with a moveable closure for easy filling and a frame design that reduces strain on fittings, enhancing airflow and fluid circulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a traditional cooling assembly design is used, then the assembly can cool hydraulic fluid, but the assembly is bulky and does not optimize space utilization
Solution Approach 1:
The reservoir is designed with an air chamber nested within its structure. The air chamber occupies the space above the fluid level, allowing the cooling assembly to perform both fluid storage and air cooling functions within a single integrated volume, thereby reducing overall assembly bulk while maintaining cooling efficiency
Solution Approach 2:
The reservoir serves multiple functions simultaneously: it stores hydraulic fluid, houses the air chamber for cooling operations, and provides structural support for mounting fittings and hoses. This multi-functionality eliminates the need for separate components, optimizing space utilization without compromising cooling performance
2Reliability
If fittings are positioned in traditional locations, then the assembly can be assembled, but strain on fittings can cause leaks
Solution Approach 1:
The reservoir features specifically designed receptacles at its ends that provide optimized mounting locations for fittings and hoses. These receptacles are positioned to minimize strain and stress concentrations on connected components, thereby reducing leak risks without requiring complex additional support structures
Solution Approach 2:
The receptacles are pre-integrated into the reservoir structure during manufacturing, with predetermined optimal positions for fitting installation. This preliminary preparation ensures that fittings are installed at locations that inherently reduce strain and stress, preventing leaks before operation begins without requiring complex assembly procedures
3Ease of operation
If the closure is fixed in position, then the assembly structure is simple, but the fill entry is not accessible by operator hands
Solution Approach 1:
The closure is designed to be moveable rather than fixed, allowing it to be opened to a position where the fill entry is easily accessible to operator hands for refilling operations. The closure can be moved between a closed position for sealing and an open position for access, providing operational flexibility without requiring complex additional mechanisms
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 assembly effectively cools hydraulic fluid, reduces strain on fittings, and improves operational efficiency by optimizing space and airflow, preventing overheating and potential leaks.
Implementation Method 1
a heat exchanger; a fan; a fan motor coupled to the fan... As the fluid passes through the heat exchanger, it is cooled by air being drawn through the heat exchanger

AI summary
A mobile hydraulic cooling assembly has a hydraulic fluid reservoir with a second interior surface offset from a first interior surface. The portion of the second surface offset is not opposite any of the first interior surface in the vertical direction. An air chamber, into which air passes into or out of through a heat exchanger, has an angled exterior surface formed from the reservoir which delimits the air chamber. A fill entry closure which covers a fill entry into the reservoir is accessible by the hands of an operator when a moveable closure of the assembly is in an open position. At least two reservoir portions delimiting a hollow of the reservoir overlap a bottom facing surface and bottom of a truck rail when the cooling assembly is mounted to the truck rail.
