Pillow Support Model with Partitioned Matching Based on Body Pressure Distribution Matrix

Area of Science:

• Biomechanics
• Ergonomics
• Materials Science

Background:

• Sleep problems are a significant public health concern.
• Current pillows often lack optimized head and neck support.
• Ergonomic pillow development requires precise pressure distribution models.

Purpose of the Study:

• To construct an ideal pressure distribution model for head and neck support.
• To guide the development of advanced ergonomic pillows.
• To enhance sleep quality through improved pillow design.

Main Methods:

• Body pressure distribution experiments were conducted on memory foam pillows with human subjects.
• Fuzzy clustering and hierarchical analysis were used to define support surface partitions and pressure sensitivity weights.
• A pillow prototype was designed using extracted ergonomic node coordinates and material properties.

Main Results:

• An ideal seven-partition support model was constructed, detailing pressure distribution for supine and lateral positions.
• The model successfully guided the design of a pillow prototype that reproduced the ideal pressure distribution.
• Key ergonomic node coordinates were identified for different user groups.

Conclusions:

• The seven-partition ideal support model effectively addresses head and neck support needs in various sleeping positions.
• This model provides a strong foundation for developing next-generation ergonomic sleep products.
• Optimized pressure distribution in pillows can contribute to improved sleep health.
