Method for producing bedlinen and the like, in particular a closable pillowcase or duvet cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing bed linen, such as duvet and pillow covers, are complex and expensive due to the use of conventional seams and closure mechanisms like zippers or press studs, which require labor-intensive reworking to make them downproof.
Innovation Solution
A method involving the use of pressure-sealing strips that are glued along the edges of textile webs, allowing for a seamless and cost-effective production of bed linen covers without the need for sewing or complex closure mechanisms, using hot-melt adhesive for all adhesive seams and strips, and snap fastener strips that can be easily aligned and engaged for closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional seams are used to connect textile layers and attach closure means, then the bed linen cover can be assembled, but the manufacturing process becomes complex and expensive due to labor-intensive reworking to make seams downproof
Solution Approach 1:
The invention extracts the problematic seam construction from the manufacturing process by replacing it with adhesive bonding. The adhesive strips are applied directly to connect textile layers and attach closure means, eliminating the need for complex seam assembly and subsequent downproof reworking, thus simplifying manufacturing while reducing device complexity
Solution Approach 2:
The invention replaces the mechanical sewing system with an adhesive bonding system. Instead of using needles and threads to create seams that require labor-intensive reworking, hot-melt adhesive is applied to connect textile layers and attach closure means, transforming the mechanical connection process into a thermal bonding process that is simpler and more cost-effective
2Reliability
If adhesive strips are used to seal seams for downproof conditioning, then the seams become downproof, but the manufacturing process becomes more complex and expensive
Solution Approach 1:
The invention merges the seam connection function and the downproof sealing function into a single adhesive bonding step. The same hot-melt adhesive that connects textile layers also provides downproof sealing, eliminating the need for separate seam construction and subsequent sealing operations, thus maintaining reliability while simplifying manufacturing
Solution Approach 2:
The hot-melt adhesive serves multiple functions simultaneously: it connects textile layers together, attaches closure means to the cover, and provides downproof sealing to prevent down escape. This multi-functionality eliminates the need for separate operations for each function, simplifying the manufacturing process while ensuring reliable downproof performance

Function Achieved in This Case
This method simplifies the manufacturing process, reduces costs, and allows for efficient production of bed linen covers that can be easily opened and closed, while maintaining a downproof seal, without the need for complex seams or additional closure mechanisms.
Implementation Method 1
fixing the folded edge by gluing the contacted underside sections
Implementation Method 2
using hot-melt adhesive for all adhesive seams and strips
Implementation Method 3
The snap fastener lips may be formed of a resilient plastic material to allow multiple opening and closing of the snap fastener formed by the complementary snap fastener strips
