Threaded Tube Position Adjustment for Adjustable Pillow Height Limits
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
2Adaptability or versatility

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
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.
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.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the pillow to be adjusted to specific descending and lifting heights, enhancing user comfort by accommodating various sleeping positions and requirements.
Implementation Method 1
a threaded sleeve is connected with the first opening and is screwed with a threaded tube, such that the threaded tube is adjustably moved relative to the threaded sleeve

AI summary
A position adjustment mechanism for a lifting balance device (2) contains: a first cover (11) and an adjustment device (3). The first cover (11) includes at least one lifting balance device (2), and each of the at least one lifting balance device (2) includes a first support (21), a second support (22) intersected with the first support (21), and a shaft (23) configured to connected the first and second support (22)s. The adjustment device (3) is located bellow the shaft (23). The adjustment device (3) is fixed inside the first cover (11), the first cover (11) has a first opening (111) located below the shaft (23). A threaded sleeve (31) is connected with the first opening (111) and is screwed with a threaded tube (33), such that the threaded tube (33) is adjustably moved relative to the threaded sleeve (31) so as to change a position of a top of the threaded tube (33) and to limit a lowest descending position of each of the first support (21) and the second support (22).
