Integrated mould-pressing pillowcase and mould-pressing forming device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional polyester fabric pillowcases have a poor stability and high production costs due to multiple connection steps, leading to longer production cycles and lower yield, with issues of relative displacement between the pillowcase and pillow inner affecting comfort and uniformity.
Innovation Solution
An integrated mold-pressing pillowcase design where the pillowcase top layer, bottom layer, and peripheral wall are formed in one piece using polyester fabric, with a window position for the pillow inner and heat-curing positioning corner ends, facilitated by a mold-pressing forming device that includes a pillowcase mold base and heat-setting pillow inner mold for streamlined production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional adhesive bonding, quilting, or thermal compounding modes are used to connect the pillowcase, pillowcase periphery, and pillowcase bottom surface, then the pillowcase can be formed through multiple steps, but the forming cost increases and the relative combination stability deteriorates
Solution Approach 1:
The patent merges the pillowcase top layer, pillowcase periphery, and pillowcase bottom surface into a single integrated structure formed by one-piece mold-pressing of polyester fabric. This eliminates the need for separate connection steps (adhesive bonding, quilting, or thermal compounding) between these components, thereby reducing device complexity while improving combination stability through integral forming.
2Ease of manufacture
If multiple connection steps are used to form the pillowcase structure, then the pillowcase can be assembled, but the production cycle lengthens and productivity decreases
Solution Approach 1:
The patent performs preliminary action by pre-forming the entire pillowcase structure (top layer, periphery, and bottom surface) as a single integrated piece through one-piece mold-pressing before final assembly. This eliminates subsequent connection operations, significantly shortening the production cycle and improving productivity while maintaining ease of manufacture through the integrated forming process.
3Shape
If traditional mold-pressing forms only the pillowcase top layer, then the top surface can be shaped, but additional connection steps are required for the periphery and bottom surface, increasing cost and reducing uniformity
Solution Approach 1:
The patent merges the forming processes of the pillowcase top layer, periphery, and bottom surface into a single one-piece mold-pressing operation. This ensures that all components are formed simultaneously under the same molding conditions, eliminating variations introduced by separate connection steps and significantly improving product uniformity and manufacturing precision.
