Cockpit Module Duct Structure for Large Center Speaker Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing size of center speakers with AI and moving functions interferes with conventional HVAC devices in vehicle cockpit modules, leading to installation challenges.
Innovation Solution
A vehicle cockpit module assembly is designed with a cowl crossbar assembly, a duct connecting part, an air conditioning module, and a defrost duct, allowing the center speaker to be seated on the duct connecting part, which is integrated with the cowl crossbar assembly and air conditioning module, using materials like polypropylene and glass fiber for structural support and weight reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the center speaker size is increased to accommodate AI and moving functions, then the speaker's functionality is improved, but it interferes with the conventional HVAC device installation
Solution Approach 1:
The HVAC system is segmented into separate functional components: the air conditioning module remains distinct from the duct connecting part, allowing the center speaker to be installed on the duct connecting part without interfering with the air conditioning module's operation. This segmentation enables independent positioning and sizing of each component.
Solution Approach 2:
The center speaker is relocated from the conventional HVAC device position to the duct connecting part, which is a different spatial dimension within the cockpit module. This dimensional repositioning allows the larger speaker to coexist with the air conditioning module without interference.
2Device complexity
If the center speaker is installed on the conventional HVAC device, then the layout is simplified, but the speaker and HVAC device interfere with each other
Solution Approach 1:
The center speaker is extracted from the conventional HVAC device and repositioned on the duct connecting part. This extraction eliminates the harmful interference between the speaker and air conditioning module while maintaining a relatively simple overall layout through integrated coupling of the duct connecting part with the cowl crossbar assembly.
Solution Approach 2:
The duct connecting part serves as an intermediary structure that supports the center speaker while connecting the air conditioning module to the ventilation system. This intermediary positioning allows the speaker to be integrated into the cockpit module without directly interfering with the air conditioning module's functionality.
3Productivity
If additional brackets and jig devices are installed for cockpit module transfer, then the module can be transferred to the vehicle completion line, but the device complexity increases
Solution Approach 1:
The duct connecting part is integrally coupled with the cowl crossbar assembly, merging the speaker mounting function with the structural support function. This integration reduces the need for separate brackets and transfer equipment, as the integrated structure can be handled as a single unit during transfer to the vehicle completion line.
