Side sleeper pillows having vented earhole features
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing side sleeper pillows with earholes suffer from poor ventilation and air circulation, leading to pressure fluctuations and elevated temperatures, which detract from sleeper comfort and reduce the pillow's stability during use.
Innovation Solution
Incorporating vented earhole features with earholes and vent channels that maintain fluid communication between the ambient environment and the earhole, even when covered by the head, to minimize pressure fluctuations and promote airflow, while strategically positioning vent channels to prevent collapse and enhance structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If earholes are incorporated into the pillow to relieve pressure on the ear region, then sleeper comfort is improved, but ventilation and air circulation become poor leading to pressure fluctuations and elevated temperatures
Solution Approach 1:
The patent incorporates a porous foam material into the pillow structure, specifically forming a recessed region with porous walls that allows air permeation. This porous structure enables continuous air circulation through the earhole region, preventing heat accumulation and pressure fluctuations while maintaining the pressure-relief function of the earhole.
Solution Approach 2:
The pillow is divided into distinct functional regions: a principal head support surface, an earhole recessed region, and a porous foam material section. This segmentation allows the earhole area to be optimized for ventilation independently from the overall pillow structure, enabling air flow paths that prevent heat buildup while maintaining comfort.
2Ease of operation
If earholes are formed in the principal head support surface to reduce pressure on the ear, then sleeper comfort is enhanced, but the pillow's stability and structural integrity are reduced
Solution Approach 1:
The earhole is designed as a recessed region nested within the principal head support surface, rather than a complete through-hole. The porous foam material is nested within this recessed region, creating a multi-layered structure that maintains the outer surface integrity while providing internal ventilation and pressure relief functionality.
Solution Approach 2:
The pillow structure is modified locally at the earhole region with a recessed design and porous foam material, while the rest of the principal head support surface maintains its original stable structure. This localized modification provides pressure relief functionality without compromising the overall structural integrity and stability of the pillow.
3Temperature
If vent channels are added to improve air circulation through the earhole, then heat accumulation is reduced, but the device complexity increases
Solution Approach 1:
Instead of creating complex engineered vent channels, the patent uses porous foam material that provides distributed air flow paths throughout the recessed region. The porous structure naturally allows air permeation through its interconnected voids, eliminating the need for precise channel geometry while achieving effective ventilation and heat dissipation.
Solution Approach 2:
The porous foam material inherently provides the ventilation function through its natural porous structure, without requiring additional engineered channels or complex mechanisms. The material's intrinsic properties enable air circulation and heat dissipation, simplifying the overall design while maintaining effectiveness.

Function Achieved in This Case
The vented earhole design improves comfort by reducing pressure fluctuations and heat accumulation, enhancing airflow, and maintaining the pillow's stability and structural integrity, resulting in improved head support and sleep quality.
Implementation Method 1
a vent channel formed in the pillow and extending from the earhole to an outer peripheral wall of the pillow to enable fluid communication between an ambient environment and the earhole when covered by the head of the sleeper

AI summary
Embodiments of a side sleeper pillow are provided having vented earholes and other features for comfortably supporting the head of a sleeper when laying on his or her side. In various embodiments, the side sleeper pillow includes a pillow body having an outer periphery, a primary head support surface, and a first vented earhole feature. The first vented earhole feature includes, in turn, a first earhole having a first opening formed in the primary head support surface, as well as a first vent channel at least partially formed in the pillow body. The first vent channel extends from the first earhole to the outer periphery of the pillow body to enable fluid communication between an ambient environment and the first earhole when covered by the head of the sleeper.
