Baffled Pillow Structure for Filling Control and Balanced Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pillow designs with complex interior baffle arrangements that restrict filling movement are expensive to manufacture, making them impractical, while also requiring a balance between support and comfort, which is difficult to achieve with traditional fillings like feathers and down.
Innovation Solution
A pillow structure comprising two identical inner shell layers with angled or curved baffle members between them, secured by outer shell layers, which prevents filling migration and provides a combination of support and comfort using feathers and down fillings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex interior baffle arrangements are used to restrict filling movement, then filling control is improved, but manufacturing cost increases
Solution Approach 1:
The pillow is divided into multiple interior chambers using simple baffle members that extend between the inner shell layers. These baffles segment the filling into distinct zones, providing effective filling control without requiring complex arrangements. The segmentation principle allows the pillow to maintain filling position while using straightforward, cost-effective baffle structures.
Solution Approach 2:
Different regions of the pillow have different baffle configurations tailored to local needs. The baffles are positioned and angled to provide appropriate filling restriction in specific areas while leaving other areas more open. This local differentiation achieves effective filling control without uniformly complex structures throughout the entire pillow.
2Strength
If feathers are used for good support, then support is improved, but comfort decreases
Solution Approach 1:
Different filling types are placed in different interior chambers created by the baffles. Feathers or feather-like synthetic fills are positioned in areas requiring support, while softer down or down-like fills are placed in areas prioritizing comfort. This spatial differentiation of filling properties allows the pillow to simultaneously provide both support and comfort in different zones.
Solution Approach 2:
The pillow uses a composite filling arrangement combining multiple filling types (feathers and down, or synthetic equivalents) within the same pillow structure. This composite approach leverages the supportive qualities of feathers and the comfortable qualities of down, achieving a balance between support and comfort that neither filling type could provide alone.
3Ease of operation
If down is used for comfort, then comfort is improved, but support decreases
Solution Approach 1:
Down or down-like fills are strategically positioned in interior chambers where comfort is prioritized, such as areas that contact the user's face or head. Meanwhile, other chambers contain feather or feather-like fills for support. This localized placement ensures comfort where needed without sacrificing overall support structure.

AI summary
The pillow includes first and second substantially identical inner shell layers and first and second substantially identical outer shell layers. The first and second inner layers and first and second outer layers are secured together around the peripheries thereof. Extending laterally across the pillow in the width dimension are two spaced baffle members which are secured to the two inner shell layers and extend between the two inner shell layers, defining three chambers along the length of the pillow. The two baffle members either angle away from each other from one longitudinal edge of the pillow to the other longitudinal edge or extend parallel or slightly toward each other from the one longitudinal edge to a point approximately 12 inches from the one longitudinal edge and then curve away from each other to the other longitudinal edge of the pillow.
