Tire Sound Absorption Module for Roll-and-Brake Noise Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing roll-and-brake test systems require expensive soundproof booths to reduce noise radiated from tires during the test process, which increases costs and poses health risks to workers.
Innovation Solution
A sound absorption and isolation module is designed to cover only the tires of a vehicle during the roll-and-brake process, utilizing a box outer plate, sound isolation sheet, and sound absorption material to reduce noise, eliminating the need for a soundproof booth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a soundproof booth is installed to reduce tire noise, then noise isolation is improved, but investment cost and device complexity increase
Solution Approach 1:
The patent divides the noise control function into separate components: a sound isolation sheet attached to the box outer plate and a sound absorption material filling the internal cavity. This segmentation allows each component to perform its specific function (isolation vs. absorption) efficiently, replacing the need for a complete soundproof booth while maintaining noise reduction effectiveness.
Solution Approach 2:
The patent extracts the essential noise control functionality from the complex soundproof booth structure. By taking out only the critical elements (isolation barrier and absorption material) and applying them directly to the tire testing apparatus, it achieves noise reduction without the overhead of a full soundproof enclosure, thereby reducing device complexity and cost.
2Object-affected harmful factors
If a soundproof booth is installed to reduce tire noise, then noise isolation is improved, but investment cost increases
Solution Approach 1:
The patent employs relatively inexpensive materials for sound isolation (sheet material) and sound absorption (foam or fibrous material) compared to the cost of constructing a permanent soundproof booth. These materials can be easily replaced or adjusted, providing cost-effective noise control that significantly reduces investment costs while maintaining adequate noise isolation for tire testing.
3Object-affected harmful factors
If a soundproof booth is installed to reduce tire noise, then worker health is protected, but work efficiency deteriorates
Solution Approach 1:
The patent applies sound control measures locally at the tire testing position rather than enclosing the entire workspace. The sound isolation sheet and absorption material are positioned specifically around the tire and roller area where noise is generated, providing adequate protection for workers while maintaining an open and efficient work environment, thus preserving work efficiency.
