Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing assembly method for heat exchange systems, particularly those with a radiator, condenser, and sub-cooler, is tedious and lacks precision due to the multiplicity of fixing zones, making it difficult to assemble efficiently.
Innovation Solution
A heat exchange system design where the first and second heat exchangers are fixed to a common support via tongues that engage with a single fixing tab, supplemented by additional fixing elements, ensuring precise alignment and simplified assembly through vertical translational movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple fixing zones are used to secure heat exchangers to the support, then the assembly becomes more secure and stable, but the assembly process becomes more complex and time-consuming
Solution Approach 1:
The patent combines multiple fixing functions into a single integrated fixing tab structure. The fixing tab includes a first tab portion for engaging the first heat exchanger and a second tab portion for engaging the second heat exchanger, allowing both components to be secured to the support through one unified fixing element rather than separate fixing zones. This reduces assembly complexity while maintaining reliable fixation of both heat exchangers.
2Reliability
If multiple separate fixing elements are used for each heat exchanger, then each component can be securely fixed, but the overall bulk and number of fixing means increase
Solution Approach 1:
The invention merges the function of multiple separate fixing elements into a single fixing tab that simultaneously secures both the first and second heat exchangers. The fixing tab is configured with specific geometries including a first tab portion with a first engagement feature for the first heat exchanger and a second tab portion with a second engagement feature for the second heat exchanger, thereby reducing the quantity of fixing elements from two or more separate components to one integrated component.
Solution Approach 2:
The fixing tab serves multiple functions within a single component: it provides structural support for both heat exchangers, enables precise positioning of both components, and secures both heat exchangers to the support structure. This multi-functional design eliminates the need for separate fixing elements for each heat exchanger, reducing the overall number of fixing means while maintaining secure fixation.
3Device complexity
If a unified fixing structure is used for multiple heat exchangers, then the number of fixing elements is reduced, but the precision of positioning each heat exchanger may be compromised
Solution Approach 1:
The fixing tab incorporates locally differentiated features to ensure precise positioning of each heat exchanger. The first tab portion includes a first engagement feature with specific dimensional characteristics optimized for the first heat exchanger, while the second tab portion includes a second engagement feature with different dimensional characteristics optimized for the second heat exchanger. This local differentiation within the unified fixing structure maintains positioning precision for each component while keeping the overall structure simple and integrated.
