Solution Overview
Problem
Existing airbags in mattresses suffer from poor high-temperature resistance, leading to deformation and reduced telescopic function over time due to temperature changes, affecting their ability to provide consistent support.
Innovation Solution
Incorporating modified chlorinated butyl rubber into the airbags, combined with carbon black, vulcanizing agents, and radiation vulcanization, enhances their high-temperature resistance and mechanical properties, allowing for frequent inflation and deflation without shape change.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional airbag materials are used in mattresses, then the airbags can be easily manufactured and inflated, but they exhibit poor high-temperature resistance and are prone to deformation after prolonged use
Solution Approach 1:
The patent uses composite rubber materials comprising chlorinated butyl rubber (40-60 parts), butyl rubber (20-40 parts), and ethylene propylene rubber (10-30 parts) to create airbags with improved high-temperature resistance. This composite material system combines the advantages of different rubber types to achieve both thermal stability and shape retention under elevated temperatures.
Solution Approach 2:
The patent modifies the chemical composition and crosslinking density of the rubber material through specific compounding formulations and vulcanization processes. By adjusting the ratios of different rubber components and adding appropriate vulcanizing agents, the material's glass transition temperature and thermal stability parameters are optimized to resist deformation at high temperatures.
2Productivity
If airbags are frequently inflated and deflated, then the telescopic function is enhanced, but the airbags undergo deformation and lose support performance over time
Solution Approach 1:
The multi-component rubber composite provides balanced mechanical properties including elasticity, tensile strength, and fatigue resistance. The combination of chlorinated butyl rubber, butyl rubber, and ethylene propylene rubber creates a material that can withstand repeated inflation-deflation cycles while maintaining support performance and structural integrity.
Solution Approach 2:
The airbags are designed with specific curved geometries that distribute stress evenly during inflation and deflation cycles. The spherical or ellipsoidal shapes allow for uniform expansion and contraction, reducing localized stress concentrations that would otherwise lead to deformation and failure over time.
3Shape
If high-temperature resistant materials are used in airbags, then shape stability is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent optimizes the vulcanization process parameters including temperature (140-160°C), time (10-20 minutes), and pressure to achieve complete crosslinking of the composite rubber material. By carefully controlling these parameters, the manufacturing process remains simple while ensuring the material achieves its full high-temperature resistance potential.
Solution Approach 2:
The composite rubber formulation is designed to be self-vulcanizing within the specified temperature and time ranges. The material automatically achieves optimal crosslinking and shape stability through the vulcanization process without requiring complex multi-step manufacturing procedures or specialized equipment, thereby maintaining ease of manufacture while achieving high-temperature resistance.
