Dual-Pivot Armrest Assembly for Adjustable Procedure Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing salon chair armrest assemblies lack adequate adjustability to comfortably support individuals of different sizes during manicure and other procedures.
Innovation Solution
The armrest assembly features a device frame with a frame pivot connecting the frame bracket to the device frame, allowing the arm support to pivot relative to the device frame, and a support arm pivot connecting the arm support to the frame bracket, enabling improved adjustability. Additionally, the arm support includes a fluid bowl secured to the support base, which can pivot to prevent fluid spillage and be easily inserted or removed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing armrest assemblies use a fixed structure, then the device complexity is low, but the adaptability to different user sizes is insufficient
Solution Approach 1:
The armrest assembly incorporates two pivots: a frame pivot connecting the frame bracket to the device frame, and a support arm pivot connecting the arm support to the frame bracket. This dynamic structure allows the arm support to assume multiple positions and orientations, enabling adjustment to accommodate users of different sizes while maintaining a relatively simple overall structure.
2Reliability
If the fluid bowl is securely retained to the arm support, then the reliability preventing fluid spillage is improved, but the ease of operation for insertion and removal is reduced
Solution Approach 1:
The arm support itself is designed to pivot relative to the frame bracket through the support arm pivot. This dynamic capability allows the fluid bowl to be securely retained during use (when the arm support is in position) while enabling easy insertion and removal (when the arm support is pivored to an accessible position), thus resolving the contradiction between reliability and ease of operation.

AI summary
A resting device assembly for supporting a person during a procedure includes a resting device and an armrest. The resting device supports the person during the treatment and includes a device frame. The armrest includes an arm support, a frame bracket, a frame pivot, and a support arm pivot. The arm support supports an arm of the person. The frame pivot connects the frame bracket to the device frame, and allows the frame bracket and the arm support to concurrently pivot relative to the device frame. The support arm pivot connects the arm support to the frame bracket and allows the arm support to pivot relative to the frame bracket. In certain embodiments, the two pivots of the armrest assembly allows for improved adjustability of the armrest. As a result thereof, the person is more comfortable during the manicure or other procedure.
