Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic systems require external cooling devices connected to tanks via hoses and pipelines, which occupy space and are vulnerable to damage, and lack efficient cooling solutions.
Innovation Solution
Integrating a compact cooling device with a heat exchanger and fluid working machine directly into the tank, eliminating the need for external connections and protective housings, and using a partition wall with valves to manage fluid flow and prevent oil mixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If an external cooling device is provided for the hydraulic oil, then cooling function is achieved, but space is occupied and the system becomes complex
Solution Approach 1:
The cooling device is integrated directly into the tank structure, merging two separate components (tank and cooling device) into a single unified structure. This eliminates the need for external cooling devices connected by hoses and pipelines, thereby reducing system complexity while maintaining the cooling function.
2Temperature
If an external cooling device is provided for the hydraulic oil, then cooling function is achieved, but space is occupied
Solution Approach 1:
The cooling device is merged with the tank structure, utilizing the tank's own space for cooling functionality. This integration eliminates the need for separate external cooling devices and their connecting infrastructure, thereby reducing the total space occupation while achieving the cooling function.
3Temperature
If external hoses and pipelines are used to connect cooling device to tank, then cooling function is achieved, but vulnerability to damage increases
Solution Approach 1:
The cooling device is integrated into the tank structure, eliminating external hoses and pipelines that are vulnerable to damage. The unified structure removes the weak links in the system, thereby improving reliability while maintaining the cooling function.
4Ease of manufacture
If cooling device is positioned outside the tank, then installation is simple, but protection against damage is insufficient
Solution Approach 1:
The cooling device is integrated into the tank structure, which naturally provides protection against damage from stone chipping, foreign bodies, and corrosion. The tank's structural integrity serves as protective housing for the cooling device, eliminating the need for separate protective housings while simplifying the overall design.
