Solution Overview
Problem
Inflatable products made from PVC materials deform under high internal pressure and are environmentally unfriendly due to slow degradation, leading to increased material costs and environmental pollution.
Innovation Solution
The use of internal tensioning members with helically wound threads directly fixed to the walls of the inflatable product, reducing material usage and production costs while enhancing tensile resistance, and made from materials like cotton, polyester, or polypropylene, which are more environmentally friendly.
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 is environmentally unfriendly
Solution Approach 1:
The patent uses composite materials consisting of fabric layers (such as polyester, polypropylene, or cotton) combined with elastic materials. The fabric layers provide high tensile strength and resistance to deformation under pressure, while the elastic material allows for welding and flexibility. This composite structure resolves the contradiction between ease of manufacture and tensile resistance by combining materials with complementary properties.
2Stability of the object's composition
If more PVC material is used to reduce deformation, then the deformation resistance improves, but material costs increase and environmental degradation pressure increases
Solution Approach 1:
By using fabric layers combined with elastic materials, the patent achieves high deformation resistance without requiring excessive material quantity. The fabric structure provides inherent stiffness and strength, allowing the tensioning members to maintain shape under pressure while using less material overall compared to solid PVC constructions.
Solution Approach 2:
The patent applies different materials with specific properties to different functional requirements: fabric layers are used where tensile strength and deformation resistance are needed, while elastic materials are used where welding and flexibility are required. This localized material assignment optimizes performance while minimizing overall material consumption.
3Strength
If helically wound threads are used for internal tensioning members, then the tensile resistance is enhanced and material usage is reduced, but the manufacturing complexity increases
Solution Approach 1:
The patent divides the internal tensioning member into distinct segments: fabric layers and elastic material layers. This segmentation allows each component to be manufactured separately using conventional techniques, then combined through lamination. The helical winding pattern is applied to the fabric layers, which are then laminated with elastic materials, breaking down the complex manufacturing into manageable steps.
Solution Approach 2:
The composite structure of fabric and elastic material layers simplifies manufacturing compared to creating entirely new complex structures. The fabric layers can be woven or knitted in helical patterns using standard textile processes, then laminated with elastic materials using established lamination techniques, making the overall manufacturing process more feasible despite the enhanced functional requirements.
4Object-affected harmful factors
If natural fibers or synthetic fibers are used for internal tensioning members, then the environmental friendliness improves, but the welding capability is reduced
Solution Approach 1:
The patent creates a composite material system where fabric layers made from environmentally friendly fibers (natural or synthetic) are laminated with elastic material layers. The fabric layers provide ecological benefits and structural strength, while the elastic material layers maintain welding capability. This composite approach allows the product to be environmentally friendly while retaining ease of manufacture through welding.
Solution Approach 2:
The elastic material layers act as an intermediary between the non-weldable fabric layers and the welding process. During manufacturing, the elastic material layers are laminated to the fabric layers, creating a composite structure where the elastic material serves as the weldable interface, allowing conventional welding techniques to be applied to products containing environmentally friendly but non-weldable fiber materials.
