Vacuum-Packed Pillow Compression That Preserves Loft Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pillows face challenges in reducing storage space without compromising their ability to rebound to their original shape after compression, as existing methods like rolling result in unstable and deformed pillows, while vacuum compression often leads to over-compression and loss of loft.
Innovation Solution
A space-saving pillow system using a hollow-siliconized garnetted polyester fill and a bag that compresses the pillow to no more than 80% of its original size, allowing it to rebound fully, utilizing vacuum-packing and heat sealing techniques to maintain the pillow's integrity and loft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If pillows are compressed by vacuum packing to reduce storage space, then the storage space is reduced, but the pillow becomes over-compressed and loses its ability to rebound to its original shape
Solution Approach 1:
The patent changes the compression parameter from excessive vacuum compression to controlled compression within specific limits (no more than 80% compression). This parameter optimization allows the pillow to be compact for storage while preserving the fill material's elastic recovery properties, enabling it to rebound to its original shape after decompression.
2Volume of moving object
If pillows are rolled to reduce storage space, then the storage space is reduced, but the pillow arrangement becomes difficult to secure and stabilize
Solution Approach 1:
The patent uses a flexible plastic bag to enclose the pillow, replacing the rolled configuration. The bag provides a stable, secure enclosure that maintains the pillow's shape during storage and transport, eliminating the instability and difficulty of securing rolled pillows while still achieving space reduction through controlled compression.
3Volume of moving object
If pillows are compressed beyond 80% of original size, then storage space is maximized, but the pillow remains deformed and cannot rebound properly
Solution Approach 1:
The patent establishes a critical compression threshold of 80% of original size as the optimal parameter. By controlling the compression to not exceed this threshold, the pillow achieves sufficient space reduction for storage while preserving the structural integrity and elastic properties of the fill material, ensuring it can rebound to its original shape after decompression.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The pillow effectively reduces storage space while maintaining its ability to fully rebound to its original shape and loft, providing optimal space-saving benefits without compromising comfort or functionality.
Implementation Method 1
The fill is adapted to be compressed and generally rebound back to its natural state upon decompression
Implementation Method 2
vacuuming the air out of the bag so as to compress the space saver pillow to no more than approximately 80% of its original size
Implementation Method 3
heat sealing the bag

AI summary
A space saver pillow system comprises a space saver pillow and a bag. The space saver pillow includes a fill and a covering surrounding and enclosing the fill. The fill of the space saver pillow is adapted to generally rebound back to its natural state after being compressed. The bag encloses the space saver pillow and an amount of air. The space saver pillow enclosed in the bag is compressed no more than about 80% of its original size.
