Adjustable Cervical Pillow Geometry for Multi-Position Neck Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cervical pillows on the market have limited adjustability and do not effectively accommodate varying body sizes and sleeping positions, leading to suboptimal alignment and comfort for users.
Innovation Solution
A multi-position cervical pillow with asymmetrical lobes and a shallow trough, combined with an ancillary pillow pad for customizable elevation, inclination, and cervical curvature, allowing users to stack and slide components for virtually unlimited position adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a universal single pillow pad construction with two lobes is used, then the pillow can provide two positions with different contoured curvatures, but it cannot effectively accommodate varying body sizes and sleeping positions
Solution Approach 1:
The pillow is divided into multiple independent components: a base pillow pad with asymmetrical lobes, an ancillary pillow pad, and adjustable wedges. These segments can be stacked and rearranged to create different configurations, allowing the pillow to adapt to various body sizes and sleeping positions while maintaining relatively simple individual component designs
Solution Approach 2:
The pillow system transitions from a static single-pad design to a dynamic multi-component system where components can be stacked, unstacked, and repositioned. This dynamic configuration allows users to adjust the pillow's elevation, inclination, and cervical curvature based on their specific needs, significantly improving adaptability
2Adaptability or versatility
If multiple removable components are used to achieve adjustability in height and firmness, then the pillow can be customized for different users, but the pillow becomes cumbersome to adjust and dispose
Solution Approach 1:
The pillow system uses a small number of clearly segmented components (base pad, ancillary pad, wedges) that can be easily separated and recombined. This segmentation enables simple stacking and unstacking operations without complex assembly or disassembly procedures, maintaining ease of operation while achieving customizability
Solution Approach 2:
The ancillary pillow pad and wedges serve multiple functions: they can be stacked to adjust elevation, positioned to modify inclination, and arranged to change cervical support. This multi-functionality reduces the number of separate components needed, simplifying both adjustment and disposal operations

AI summary
The present invention pertains to a multi-position cervical pillow and an adjustable pillow set thereof to support a user's head and neck. In a preferred embodiment, the multi-position cervical pillow comprises a rectangular memory foam pad, the transversal cross section of which is bone-shaped with two lobes protruded towards two opposite lateral ends and a shallow trough in between forming a concave head support portion on each of the two support surfaces; said two lobes are different in size and asymmetrical in shape. By inverting and reversing the pillow pad it provides four unique positions. An adjustable pillow set comprises a main multi-position cervical pillow and an unattached ancillary pillow, the upper surface of the latter has a transversally convex, asymmetrical curvature for the main pillow to stack and slide on top of it, forming four stacking configurations, with each providing two unique positions.
