Solution Overview
Problem
Inflatable products made from PVC materials deform under high internal pressures and environmental degradation is a concern, leading to user discomfort and ecological issues.
Innovation Solution
Inflatable products are designed with helically wound threads fixedly connected to inner walls using high-frequency welding, combining fixing strips made from materials like PVC, TPU, PET, EVA, PU, or nylon, and threads made from cotton, linen, silk, nylon, polyester, polypropylene, polyethylene, glass, or carbon fibers, reducing deformation and environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If PVC material is used for internal tensioning members, then the material can be easily welded and processed, but the material deforms under high internal pressure and has slow degradation causing environmental pollution
Solution Approach 1:
The patent uses a composite structure consisting of a fabric layer (providing tensile strength and deformation resistance) sandwiched between two PVC film layers (providing weldability and airtightness). This composite material combines the advantages of different materials to simultaneously achieve ease of manufacture and stability under pressure.
Solution Approach 2:
The invention applies different materials to different functional requirements: the fabric layer is positioned where tensile strength is needed (between the PVC layers) to resist deformation, while the PVC film layers are positioned where weldability and airtightness are needed (outer surfaces). Each material performs its specialized function locally.
2Stability of the object's composition
If more PVC material is used to improve deformation resistance, then the creep behavior is limited, but material costs increase and environmental degradation pressure increases
Solution Approach 1:
Instead of using excessive PVC material, the patent creates a composite structure where a fabric layer provides the primary deformation resistance through its inherent tensile strength. The PVC films provide minimal necessary material for weldability and airtightness, significantly reducing overall PVC consumption while maintaining or improving deformation resistance.
Solution Approach 2:
The invention changes the material composition parameter from pure PVC to a composite structure, fundamentally altering how deformation resistance is achieved. Rather than increasing the quantity of PVC, the patent transitions to a different material system (fabric + PVC composite) that provides superior deformation resistance with less material.
3Strength
If helically wound threads are used for internal tensioning, then tensile strength is improved and material consumption is reduced, but the manufacturing complexity increases
Solution Approach 1:
The patent uses helically wound threads (curved/spiral configuration) instead of straight threads. The helical structure provides superior tensile strength and elasticity while distributing stress more effectively. The curvature of the helix allows the thread to flex and expand with the inflatable product while maintaining high tensile strength.
Solution Approach 2:
The helical thread structure replicates natural tendon or cable constructions that have been proven effective for tensioning applications. This proven structural pattern is copied and adapted for inflatable products, achieving high tensile strength without requiring complex custom-designed manufacturing processes.
