Degassing Tank Support Layout for Tight EV Wheel Arch Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of a degassing tank within the cramped engine compartment of vehicles, particularly electric vehicles, is complex due to limited space and the need to reuse body components from other vehicle types, making it difficult to accommodate without costly modifications.
Innovation Solution
A compact arrangement using pre- and final positioning means, such as oblong holes, and fastening mechanisms like threaded rods and notches, secures the degassing tank to the wheel arch and side awning reinforcement, allowing it to be pivoted into place, utilizing existing vehicle interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the degassing tank is integrated within the engine compartment, then the heating system function is achieved, but the available space is insufficient and integration becomes complex
Solution Approach 1:
The degassing tank is nested within the wheel arch cavity, utilizing the space inside an existing structural component. The tank fits into the wheel arch's internal volume, effectively nesting one component within another to overcome space constraints in the engine compartment.
Solution Approach 2:
The solution transitions from two-dimensional planar space utilization to three-dimensional volumetric utilization by positioning the tank within the depth of the wheel arch cavity. This dimensional approach allows the tank to occupy vertical and depth space rather than only horizontal plane space.
2Ease of manufacture
If body components from other vehicle types are reused, then manufacturing costs are reduced, but the integration complexity increases
Solution Approach 1:
The wheel arch is designed with multi-functionality: it serves both its original structural purpose and as a mounting location for the degassing tank. The wheel arch acts as both a body component and a support structure, eliminating the need for dedicated mounting brackets or additional components.
Solution Approach 2:
The support structure for the degassing tank is merged with the wheel arch itself. Instead of adding separate support components, the wheel arch's existing structure is utilized to provide both structural integrity and tank support, combining multiple functions into a single component.
3Area of stationary object
If the degassing tank is positioned in a difficult-to-access space, then space optimization is achieved, but the installation and maintenance difficulty increases
Solution Approach 1:
The mounting system is segmented into multiple independent features: the wheel arch receiving means, the main support with pre-positioning means, and the final positioning means. This segmentation allows the tank to be installed in stages, with each feature providing a specific function that simplifies the overall installation process despite the confined location.
Solution Approach 2:
The pre-positioning means (such as an oblong hole) is provided in advance on the wheel arch, allowing the tank to be temporarily positioned and aligned before final securing. This preliminary action facilitates easier installation by providing guidance and alignment features prior to the final mounting step.
