Front Compartment Panel Sealing for Vehicle NVH Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle front compartment designs face challenges in achieving low noise, vibration, and harshness (NVH) levels while ensuring efficient climate control and easy assembly of components.
Innovation Solution
A panel structure with first and second attachment components and a sealing component is used to separate the front compartment into two sections, effectively reducing NVH by stiffening the compartment and ensuring clean air supply from the climate control system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the front compartment is designed with multiple systems and components, then the functionality and climate control capability are improved, but the NVH (noise, vibration, harshness) level inside the cabin compartment increases
Solution Approach 1:
The front compartment is divided into a first compartment (for climate control system) and a second compartment (for other systems) using a panel structure. This segmentation isolates noise and vibration sources in the second compartment from the cabin compartment, reducing NVH transmission while maintaining all required functionalities in their respective zones.
2Productivity
If the climate control system is assembled inside the narrow front compartment, then the assembly process is completed in one step, but the assembly becomes difficult and time-consuming
Solution Approach 1:
The climate control system is pre-assembled on the panel structure in a separate, more spacious location before being installed into the front compartment. This preliminary assembly allows workers to perform assembly tasks more easily and efficiently, and the pre-assembled unit can then be quickly installed as a complete module, improving both ergonomics and productivity.
3Object-affected harmful factors
If the front compartment is separated into multiple compartments, then NVH reduction and clean air supply are improved, but the structural complexity increases
Solution Approach 1:
The panel structure serves multiple functions simultaneously: it acts as a structural support for the climate control system, provides air-flow restricting sealing to separate compartments, and functions as a mounting surface for attachment components. This multi-functionality reduces the need for additional separate components, thereby managing structural complexity while achieving NVH reduction and air sealing.
4Reliability
If a sealing component is added to restrict air flow between compartments, then clean air supply to the cabin is improved, but the manufacturing complexity increases
Solution Approach 1:
The sealing component is integrated with the panel structure, combining the sealing function with the existing structural element. This integration eliminates the need for separate sealing components and reduces manufacturing steps, while still providing effective air-flow restriction to ensure clean air supply from the climate control system to the cabin compartment.
