Solution Overview

Problem

Conventional adjustable pillows cannot be adjusted to a lowest descending or highest lifting height based on user requirements, limiting their adaptability for different sleeping positions.

Innovation Solution

A position adjustment mechanism is introduced, featuring a first cover with a lifting balance device and an adjustment device that includes a threaded sleeve and tube system to adjust the lowest descending position, and a track groove mechanism to adjust the highest lifting position, allowing for customizable height settings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional adjustable pillow is used, then the pillow can be lifted to a fixed height, but it cannot be adjusted to a lowest descending height or highest lifting height based on user requirements

Engineering Contradiction:
Improveadjustability to lowest descending heightVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adjustment mechanism is divided into separate functional components: a threaded tube assembly for lowest height adjustment and a track groove assembly for highest height adjustment. This segmentation allows independent adjustment of different height parameters without requiring complete structural redesign.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces dynamic adjustment capabilities through rotatable components (threaded tube, track groove mechanism) that enable the pillow to transition between fixed and adjustable states, allowing users to dynamically modify height settings based on their needs.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If a conventional adjustable pillow is used, then the pillow can be lifted to a fixed height, but it cannot be adjusted to a highest lifting height based on user requirements

Engineering Contradiction:

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If a position adjustment mechanism with threaded sleeve and tube is added, then the pillow can be adjusted to specific descending height, but the device complexity increases

Engineering Contradiction:
Improvecustomizable height settingsVSAvoidadjustment mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces dynamic adjustment capabilities through rotatable components (threaded tube, track groove mechanism) that enable the pillow to transition between fixed and adjustable states, allowing users to dynamically modify height settings based on their needs.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The threaded sleeve acts as an intermediary component between the user's rotational input and the vertical position adjustment of the pillow. This intermediary mechanism translates rotational motion into precise linear displacement, enabling fine-tuned height adjustment.

Inventive Principle:
Principle #24Intermediary (Mediator)
