Headrest assembly for a bathtub and bathtub device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bathtub headrests are not rotatable, requiring users to detach and reattach suction cups for direction adjustment, leading to a poor user experience.
Innovation Solution
A pivotable headrest assembly with a suction cup and a headrest that can transition between two states, allowing for adjustable positioning without detachment, using an assembling shaft sleeve and a headrest with convex and concave portions for enhanced user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a suction cup is used to adhere the headrest to the bathtub wall, then the headrest can be firmly fixed, but the headrest cannot be rotated and requires detachment for direction adjustment
Solution Approach 1:
The headrest is designed with a pivotable connection mechanism that allows it to rotate between horizontal and inclined positions while remaining attached to the bathtub wall. The connection structure includes a pivot hole in the headrest and a corresponding pivot pin or sleeve on the suction cup assembly, enabling dynamic adjustment without detachment.
2Adaptability or versatility
If the headrest is designed with fixed positioning, then the structure is simple, but it cannot accommodate different user postures
Solution Approach 1:
The headrest assembly is divided into separate functional components: the suction cup for wall attachment, the pivot connection mechanism for rotation, and the headrest body with convex and concave portions for user support. This segmentation allows each component to perform its specific function while enabling overall adaptability.
Solution Approach 2:
The connection between the headrest and suction cup is designed as a pivot joint rather than a fixed connection. The headrest can rotate around the pivot pin, transitioning between a horizontal position for lying down and an inclined position for sitting, providing adaptability for different user postures.

AI summary
A headrest assembly includes a suction cup including an assembling shaft sleeve and a headrest including a headrest convex portion and a headrest concave portion. The headrest concave portion and the headrest convex portion are positioned on a same side of the headrest. The headrest is pivotably connected with the assembling shaft sleeve. The headrest is operable at a first state and a second state and configured to transition between the first state and the second state. The headrest concave portion is located obliquely above the headrest convex portion at the first state and the headrest concave portion is located obliquely below the headrest convex portion at the second state.
