Pivoting Heat Exchanger Module for Easier Passenger Car Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Access to heat exchanger modules in passenger cars is difficult due to obstruction by other components during maintenance and repair, making removal and installation challenging.
Innovation Solution
The heat exchanger module is pivotably mounted about a horizontal axis, allowing it to be pivoted between a use and non-use position, with a module mount facilitating this movement and secured in place using a screw, enabling easy access and installation without increasing structural complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the heat exchanger module is firmly attached to the passenger car using a module mount, then the reliability and stability of the heat exchanger module are improved, but the ease of repair and accessibility for maintenance work deteriorate
Solution Approach 1:
The heat exchanger module is designed with a pivotable mounting mechanism that allows it to be rotated between a horizontal position (for normal operation and stability) and a tilted position (for accessibility and maintenance). This dynamic repositioning capability resolves the contradiction between firm attachment and ease of repair.
Solution Approach 2:
The pivotable mounting mechanism is pre-configured to allow easy access to the heat exchanger module by tilting it into a accessible position before maintenance work begins. This preliminary positioning action enables maintenance personnel to access the module without difficulty while maintaining secure attachment during operation.
2Reliability
If the heat exchanger module is installed in the front region of the passenger car, then the cooling efficiency for the internal combustion engine is improved, but the accessibility for repair and maintenance work deteriorates due to obstruction by other components
Solution Approach 1:
The pivotable mounting allows the heat exchanger module to be dynamically repositioned from its optimal cooling position (horizontal in front region) to a maintenance-accessible position (tilted), resolving the contradiction between cooling efficiency and accessibility.
Solution Approach 2:
Instead of moving the heat exchanger module horizontally to improve accessibility, the invention utilizes the vertical dimension by tilting the module upward. This dimensional change allows maintenance personnel to access the module from above while maintaining its front-region location for optimal cooling.
3Stability of the object's composition
If the heat exchanger module is firmly secured in the use position, then the stability during vehicle operation is improved, but the difficulty of disassembly and removal deteriorates
Solution Approach 1:
The pivotable mounting mechanism provides stable securing in the horizontal use position through gravity and structural support, while allowing easy disassembly by tilting the module to an accessible position where fasteners can be readily removed.
Solution Approach 2:
The module is preliminarily tilted to an accessible position before disassembly begins, allowing maintenance personnel to easily access and remove fasteners without having to work in difficult-to-reach locations, thereby facilitating easy disassembly while maintaining stability during operation.
