Parallel Cooler Mounting with Elastic Members for Stress Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing working machines, such as backhoes, face challenges in efficiently cooling their prime movers and hydraulic systems due to the conventional arrangement of coolers, which can lead to reduced performance and increased maintenance needs.
Innovation Solution
A working machine design featuring a support bracket with elastic members, where a first and second cooler are arranged in parallel and secured by a fitting bracket with an additional elastic mounting member, enhancing cooling efficiency and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If coolers are arranged in series in the width direction of the machine, then the structure is compact and easy to manufacture, but the cooling efficiency is reduced due to restricted airflow
Solution Approach 1:
The patent transitions from a series arrangement (one-dimensional along width direction) to a parallel arrangement (two-dimensional across width direction) of coolers. This dimensional change allows multiple coolers to receive cooling air simultaneously, significantly improving cooling efficiency while maintaining compact structure through optimized spatial layout
2Stability of the object's composition
If rigid mounting brackets are used to secure coolers, then the installation is stable and precise, but the maintenance requirements increase due to stress concentration
Solution Approach 1:
The patent changes the mechanical properties of mounting members from rigid to elastic. The elastic mounting members can deform under thermal expansion and vibration, distributing stress evenly and preventing concentration at specific points. This maintains stable mounting while reducing maintenance needs by preventing stress-related failures
Solution Approach 2:
The elastic mounting members act as pre-configured cushioning elements that absorb thermal expansion and vibration stresses before they can cause damage to the coolers or mounting structure. This beforehand cushioning prevents stress concentration and reduces maintenance requirements
3Device complexity
If multiple coolers are mounted on a single support bracket, then the device complexity is reduced, but the stress distribution becomes uneven leading to reduced reliability
Solution Approach 1:
The patent segments the mounting function by providing individual elastic mounting members for each cooler instead of a single rigid connection point. This segmentation allows each cooler to be independently mounted with its own stress-absorbing element, ensuring even stress distribution across all coolers while maintaining a relatively simple overall structure

Function Achieved in This Case
This configuration improves cooling efficiency, reduces maintenance requirements, and enhances the overall performance of the machine by allowing for better airflow and stress distribution across the coolers.
