Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for fixing noise dampers to the inner surface of pneumatic tires are prone to separation due to bending deformation and varying temperature conditions, lacking established criteria for double-sided adhesive tapes suitable for long-term use in tires.
Innovation Solution
A method involving the use of a double-sided adhesive tape with specific criteria, including an adhesive force of at least 1.8 Newton/20 mm, cold-resistant, heat-resistant, and water-resistant properties, and a tensile strength of at least 10 Newton/10 mm-width, applied to a buffed inner surface of the tire tread portion to securely attach a sponge-based noise damper.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a double-sided adhesive tape is used to fix the noise damper to the inner surface of the tire, then the fixation process becomes simple and easy, but the adhesive tape may separate from the tire under high-temperature, very cold, or long-term service conditions due to bending deformation and compressive/tensile strain
Solution Approach 1:
The invention specifies precise parameter ranges for the adhesive tape including adhesive force (not less than 1.8 N/20mm width), tensile strength (not less than 10 N/10mm width), thickness (0.1-0.5mm), and width (5-20mm). These parameter specifications ensure the adhesive tape can withstand bending deformation, compressive and tensile strain, as well as high-temperature and cold conditions while maintaining reliable fixation of the noise damper to the tire inner surface
Solution Approach 2:
The adhesive tape serves as an intermediary element between the noise damper and the tire inner surface. By selecting an adhesive tape with specific intermediate properties (adhesive force, tensile strength, flexibility), the invention enables reliable connection that can accommodate the mechanical deformations and environmental conditions the tire experiences during service
2Reliability
If the adhesive force of the double-sided adhesive tape is increased to prevent separation, then the fixation stability improves, but the tape may become too rigid and fail to accommodate the bending deformation of the tire tread portion
Solution Approach 1:
The invention balances adhesive force and flexibility by specifying adhesive force in the range of not less than 1.8 N/20mm width while limiting tape thickness to 0.1-0.5mm. This parameter combination ensures sufficient fixation stability to prevent separation while maintaining enough flexibility to accommodate the bending deformation that occurs in the tire tread portion during operation
Solution Approach 2:
The adhesive tape is constructed as a composite structure with a base material providing flexibility and an adhesive layer providing bonding strength. This composite construction allows the tape to simultaneously exhibit both flexibility for deformation accommodation and sufficient adhesive force for stable fixation
