Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heat exchanger designs for vehicles face challenges in integration, accessibility, and compatibility with limited space and strict interface requirements, requiring a connection arrangement that is cost-effective, shock-resistant, and facilitates assembly and maintenance.
Innovation Solution
A frame for the heat exchanger comprising a first and second arm that form a loop around the exchanger, with a detachable connection to restrict movement and a hinged connection allowing pivotable movement, enabling secure attachment and easy assembly/disassembly, and incorporating elastic or integral connections for enhanced flexibility and compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid fixed connection is used to secure the heat exchanger, then stability and shock resistance are improved, but accessibility for maintenance and assembly flexibility deteriorate
Solution Approach 1:
The connection arrangement is divided into two distinct connections: a first rigid detachable connection for securing stability and shock resistance, and a second flexible hinged connection for enabling movement and accessibility. This segmentation allows each connection to fulfill different functional requirements simultaneously.
Solution Approach 2:
The second connection is designed as a hinged connection that enables dynamic movement of the first arm relative to the second arm when the first connection is detached. This dynamic capability provides accessibility for maintenance while maintaining structural integrity when assembled.
2Ease of repair
If a detachable connection is used to facilitate assembly and disassembly, then ease of maintenance is improved, but stability and shock resistance deteriorate
Solution Approach 1:
The connection arrangement is divided into two distinct connections: a first rigid detachable connection for securing stability and shock resistance, and a second flexible hinged connection for enabling movement and accessibility. This segmentation allows each connection to fulfill different functional requirements simultaneously.
Solution Approach 2:
The frame combines both rigid detachable connection features and flexible hinged connection features into a single integrated structure. This merging allows the frame to provide both stability for shock resistance and flexibility for ease of maintenance within one connection arrangement.
3Adaptability or versatility
If the frame structure is made complex to accommodate strict interface requirements and limited space, then adaptability to vehicle interfaces is improved, but device complexity increases
Solution Approach 1:
The frame with its loop structure and dual connection system serves multiple functions: it secures the heat exchanger, provides shock resistance, enables accessibility for maintenance, and adapts to strict interface requirements. This multi-functionality reduces the need for separate specialized components.
Solution Approach 2:
The hinged connection provides dynamic adaptability to accommodate different interface requirements and spatial constraints while maintaining a relatively simple overall frame structure. The ability to move when detached allows the frame to adapt to various installation configurations.
