Vehicle Engine Bay Capsule Cover Vertical Wall Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle engine bays, electric components like ECU units are degraded by heat from the engine, and their placement outside the capsule cover is limited by the need for downsizing, reducing assembly and cooling efficiency.
Innovation Solution
The engine bay structure includes a capsule cover with a side wall divided into vertical walls, allowing electric components to be attached to a specific vertical wall outside the engine, positioned between the wall and the suspension tower for improved cooling and assembly, with additional support from the suspension tower for increased rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If electric components are attached to the exterior of the capsule cover, then the electric components can be cooled appropriately, but the freedom in arranging electric components is lowered due to vehicle downsizing
Solution Approach 1:
The side wall part is divided into multiple vertical walls (first, second, third vertical walls) at different positions. This segmentation allows electric components to be attached to different vertical walls depending on spatial requirements, maintaining arrangement freedom while ensuring components are positioned outside the capsule cover for adequate cooling.
2Length of moving object
If the capsule cover is located close to vehicle-body constituting members for downsizing, then vehicle width is reduced, but the ability to assemble electric components is lowered
Solution Approach 1:
The invention utilizes the vertical dimension by providing multiple vertical walls (first, second, third) extending in the up-and-down direction at different lateral positions. This allows electric components to be attached at various heights and positions on the vertical walls, transforming a two-dimensional attachment problem into a three-dimensional solution that accommodates both compact vehicle width and component assembly requirements.
3Ease of manufacture
If the side wall part is divided into multiple vertical walls, then electric components can be easily assembled outside the capsule cover, but the structure becomes more complex
Solution Approach 1:
The multiple vertical walls serve multiple functions: they provide attachment surfaces for electric components, maintain the capsule cover's protective function, and enable thermal management by positioning components outside the cover. This multi-functionality justifies the structural division while achieving assembly ease and cooling efficiency simultaneously.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances the assembly and cooling efficiency of electric components by allowing easier placement and improved airflow, while also simplifying maintenance and reducing vehicle width.
Implementation Method 1
through an area in the engine bay between the engine and the suspension tower, the traveling wind easily passes. Thus, by disposing the electric component between the specific vertical wall and the suspension tower, cooling efficiency of the electric component can be improved.
