Method of Coating a Three-Dimensional Fabric and the Inflatable Product Made Thereof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current coating methods for three-dimensional fabrics used in inflatable products are repetitive, time-consuming, and result in uneven quality due to differences in stiffness and tension between fabric layers, leading to wrinkling and inefficient production.
Innovation Solution
A method involving guiding the three-dimensional fabric vertically with tension between 5 and 25 kg, applying adhesive to both layers simultaneously, and allowing it to dry into a film, ensuring uniform coating and reduced movement during application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive is applied to both surfaces of three-dimensional fabric using traditional coating method, then waterproofness is ensured, but both surfaces must be turned over making the process repetitive and time-consuming
Solution Approach 1:
The patent changes the coating direction from horizontal to vertical, allowing adhesive to be applied to both upper and lower surfaces of the three-dimensional fabric simultaneously as it passes through the coating device, eliminating the need to turn over the fabric and reducing coating time
2Reliability
If adhesive is applied to the upper layer of fabric, then waterproofness is improved, but the stiffness of the upper layer increases compared to the uncoated lower layer, causing tension differences and wrinkling
Solution Approach 1:
The patent combines the coating of both upper and lower fabric surfaces into a single simultaneous operation, ensuring both layers receive adhesive coating at the same time, which maintains uniform tension and prevents wrinkling while ensuring waterproofness
3Reliability
If traditional horizontal coating method is used, then adhesive can be applied to fabric surfaces, but the process is repetitive and coating efficiency is poor
Solution Approach 1:
The patent transitions from horizontal coating to vertical coating, allowing continuous passage of three-dimensional fabric through the coating device with adhesive applied to both surfaces simultaneously, significantly improving coating efficiency and productivity
Solution Approach 2:
The vertical coating method enables continuous coating operation without interruption or repetition, as the three-dimensional fabric passes through the coating device once and both surfaces are coated simultaneously, maintaining continuous productive action
