Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sound output assemblies for vehicles are complex and costly due to the requirement of multiple parts to suppress vibrational noise, which complicates their construction and increases costs.
Innovation Solution
A sound output assembly with a simplified design that includes an enclosure, a circuit board with signal processing circuitry, and a speaker assembly where the speaker's supporting members are formed as one body with the main body, providing integral vibration damping and reducing the number of parts needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an inner case is provided within the outer case with a vibration absorber interposed between the cases to suppress vibrational noise, then vibrational noise is suppressed, but the device complexity increases and manufacturing cost increases
Solution Approach 1:
The patent combines the vibration absorber function with the enclosure structure itself. The enclosure includes a vibration absorber portion that is integrated into the enclosure body, eliminating the need for a separate inner case while maintaining vibration suppression functionality. This merging of functions reduces the number of parts and simplifies the overall device structure.
Solution Approach 2:
The enclosure serves multiple functions: it houses the speaker assembly, provides structural support, and incorporates vibration absorption capabilities through the integrated vibration absorber portion. By making the enclosure multi-functional, the patent eliminates the need for separate dedicated vibration absorption components, thereby reducing device complexity.
2Object-affected harmful factors
If an inner case is provided within the outer case with a vibration absorber interposed between the cases to suppress vibrational noise, then vibrational noise is suppressed, but the manufacturing cost increases
Solution Approach 1:
The vibration absorber is integrated into the enclosure structure as a unified component rather than being a separate part. This integration reduces the number of manufacturing steps, assembly operations, and inventory requirements, thereby lowering manufacturing costs while maintaining vibration suppression effectiveness.
Solution Approach 2:
The enclosure is designed with a distinct vibration absorber portion that is integrated into the enclosure body. This segmentation of functions within a single structure allows for optimized manufacturing processes and reduces the need for multiple separate components, thereby reducing overall manufacturing cost.
3Object-affected harmful factors
If multiple parts are used to suppress vibrational noise in the sound output assembly, then vibrational noise is suppressed, but the number of parts increases and assembly complexity increases
Solution Approach 1:
The patent integrates the vibration absorption function directly into the enclosure structure, eliminating the need for separate inner cases and standalone vibration absorbers. This merging of functions reduces the total number of parts in the assembly while maintaining effective vibration noise suppression.
