Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing net-like structures struggle to achieve a balance between low resilience characteristics, cushioning properties, and durability, particularly in applications such as furniture, vehicle seats, and portable cushions, where high resilience and durability are simultaneously required.
Innovation Solution
A net-like structure with a three-dimensional random loop bonded structure made of a thermoplastic elastomer with a fiber diameter of 0.1-3.0 mm, containing 10-40% styrene content, and an apparent density of 0.005-0.30 g/cm3, featuring a 40°C compression residual strain of ≤35% and hysteresis loss of 35-85%, achieved through the use of styrene-based and polyolefin-based thermoplastic elastomers, and optionally including additives for enhanced properties.

Engineering Contradiction Analysis
1Reliability
If a styrene-based thermoplastic elastomer with 10-40 mass% styrene content is used, then low resilience characteristics are improved, but manufacturing compatibility deteriorates
Solution Approach 1:
The patent optimizes the styrene content parameter to a specific range (10-40 mass%) that balances low resilience characteristics with manufacturing compatibility. This parameter optimization ensures that the material can be effectively processed into net-like structures while achieving the desired low resilience performance.
