Modular Engine Room Housing Member for Vehicle Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing engine room structures in vehicles require multiple holes to be punched in the vehicle body for mounting components like wiring harnesses, air conditioner pipes, and ESC tubes, which weakens the vehicle's rigidity and degrades Noise, Vibration, and Harshness (NVH) performance.
Innovation Solution
A modular engine room structure featuring a U-shaped housing member with a support panel and a covering member, allowing for the embedding of components like wiring harnesses and pipes, reducing the number of holes needed and enhancing assembly efficiency and rigidity by using separable panels with protruding portions for easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple holes are punched in the vehicle body for mounting components, then components can be assembled to the vehicle body, but rigidity of the vehicle body is weakened and NVH performance is degraded
Solution Approach 1:
The patent merges multiple mounting functions into a single integrated housing member that accommodates the wiring harness, air conditioner pipe, and ESC tube together. This housing member is mounted as one unit to the vehicle body, eliminating the need for multiple separate mounting operations that would require multiple holes. The housing member acts as a consolidated structure that performs multiple mounting functions simultaneously, thereby preserving vehicle body rigidity while enabling component assembly.
Solution Approach 2:
The housing member is designed as a multi-functional component that simultaneously serves as a mounting structure for the wiring harness, air conditioner pipe, and ESC tube. This universal mounting structure replaces multiple specialized mounting points, allowing all these components to be assembled through a single housing member attachment process, thus reducing the total number of holes needed in the vehicle body.
2Ease of manufacture
If multiple holes are punched in the vehicle body for mounting components, then components can be assembled to the vehicle body, but NVH performance is degraded
Solution Approach 1:
The patent combines multiple component mounting functions into a single housing member structure that is attached to the vehicle body through one mounting location. This consolidation reduces the number of holes punched in the vehicle body, thereby minimizing disruptions to the vehicle body's structural integrity and acoustic properties, thus preserving NVH performance while still enabling complete component assembly.
3Quantity of substance
If numerous components are assembled in the engine room, then complete functionality is achieved, but assembly time increases
Solution Approach 1:
The housing member is designed to accommodate multiple components (wiring harness, air conditioner pipe, ESC tube) in a pre-configured manner. The housing member itself is prepared in advance with appropriate mounting structures and spatial arrangements, allowing numerous components to be installed simultaneously when the housing member is mounted to the vehicle body. This preliminary preparation of the housing member structure enables efficient assembly of multiple components in a single operation.
Solution Approach 2:
The patent merges the assembly of multiple components into a single integrated housing member structure. By combining the mounting functions for the wiring harness, air conditioner pipe, and ESC tube into one housing member, the assembly process for all these components can be completed in a single mounting operation, significantly reducing the total assembly time compared to installing each component separately.
4Quantity of substance
If numerous components are assembled in the engine room, then complete functionality is achieved, but the number of assembling processes increases
Solution Approach 1:
The patent merges multiple separate assembling processes into a single integrated assembly process by using one housing member to accommodate and mount all the components (wiring harness, air conditioner pipe, ESC tube) together. This consolidation reduces the complexity of the assembly process from multiple separate operations to a single unified mounting operation, making the process simpler and more manageable.
Solution Approach 2:
The housing member is designed as a universal mounting structure that can accommodate multiple different types of components through its integrated design. This multi-functional housing member eliminates the need for separate specialized mounting processes for each component type, allowing all components to be assembled through a single standardized process, thereby reducing overall process complexity.

AI summary
A structure of an engine room includes an FEM (front end module) disposed at a front side, a dash panel disposed at a rear side, and housing panels disposed at both lateral sides between the FEM and the dash panel, respectively. The structure may include a housing member including a transverse portion which is disposed to be substantially parallel to the dash panel, and longitudinal portions which are bent forward from both ends of the horizontal portion, respectively, and disposed side-by-side with the corresponding housing panels. The housing member is formed with an open interior.
