Double Open-Ended Pillowcase Design to Reduce Sorting Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bedding, such as pillowcases and duvet covers, require significant time and effort to sort and manage due to the difficulty in distinguishing between different sizes, especially in large-scale laundry operations like those in hotels.
Innovation Solution
The development of bedding with a double open-ended construction that includes foldable flaps on both ends, allowing it to accommodate two different sized pillows or duvets, thereby reducing the need for multiple SKUs and simplifying the sorting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional single open-ended pillowcases are used, then the construction is simple, but significant time is spent sorting and managing different sized pillowcases
Solution Approach 1:
The pillowcase is designed with two foldable flaps of different lengths that can be folded in different configurations to accommodate multiple pillow sizes (queen and king) within a single pillowcase, making one pillowcase serve multiple functions and eliminate the need for separate pillowcases for each size
2Productivity
If size indicators are added to pillowcases, then sorting speed improves, but the pillowcases still require identification and sorting by size
Solution Approach 1:
Different colored threads are used in the hems of the foldable flaps to indicate the intended pillow size - for example, a red thread in the hem of a flap indicates it is for a queen size pillow, while a blue thread indicates it is for a king size pillow, allowing workers to quickly identify the correct flap configuration without detailed inspection
3Reliability
If multiple SKUs are maintained for different pillow sizes, then each pillowcase fits its specific size perfectly, but inventory management and sorting time increase
Solution Approach 1:
A single pillowcase SKU with two foldable flaps of different lengths can accommodate both queen and king size pillows by folding the appropriate flap over the pillow end, eliminating the need to maintain separate inventory for different pillow sizes while ensuring proper fit for each size

AI summary
A bedding (10) including pillowcases and duvet covers that are each configured to fit two different sized bed pillows or duvets, respectively. In one embodiment, a pillowcase defines a single or double open ended construction in which a first foldable flap (24) and a second foldable flap 828) on one or both ends of the pillowcase are configured to fold over and retain one of a designated and different sized pillow, such as a queen size pillow and a king size pillow, respectively, so that one pillowcase is able to receive and retain one of two different sized pillows.
