Solution Overview
Problem
Existing massage devices lack a headrest assembly that provides optimal comfort, adjustability, and a compact design while minimizing weight and visibility, particularly in supporting the face during massage sessions.
Innovation Solution
A headrest assembly featuring a resilient assembly and a support arm system that includes a connector mechanism to inhibit pivoting, allowing for easy insertion and adjustment, with a compact configuration and aesthetically pleasing design that reduces user contact with the connector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the support arms are made rigid and fixed in position, then the headrest provides stable support, but the device becomes harder to adjust and less adaptable to different users
Solution Approach 1:
The support arms are designed with timed support mechanisms that allow them to move between extended and retracted positions. The arms can be positioned to support different head sizes and weights, providing both stability when engaged and adaptability through repositioning. The timed nature of the support allows the arms to remain in adjusted positions during use while enabling easy reconfiguration between sessions.
2Device complexity
If the arm connector is positioned near the lower face region, then the structure is simplified, but the user is more likely to contact the connector during use
Solution Approach 1:
The arm connector is repositioned from the traditional lower face region to the upper face region, changing its spatial location along the vertical dimension. This repositioning places the connector above the user's face during use, eliminating the harmful contact issue while maintaining structural connectivity. The connector remains structurally simple but operates in a different spatial zone that avoids user interaction.
3Area of stationary object
If the support arms are made longer to provide greater support, then the headrest coverage is improved, but the device weight and visibility increase
Solution Approach 1:
The support system is divided into multiple timed support arms that can be independently positioned and engaged. Rather than using one long continuous arm, the segmented arms provide distributed support coverage across the headrest area. This segmentation allows each arm to be optimized for minimal weight while collectively providing extensive support coverage through coordinated positioning.
4Volume of moving object
If the support arms are made telescopic to reduce size, then the device becomes more compact, but the structural strength may be reduced
Solution Approach 1:
The support arms incorporate telescopic mechanisms that allow them to dynamically adjust between extended and retracted states. When extended, the arms provide full structural strength for support; when retracted, they achieve compact storage. The timed support mechanism ensures that the arms are only extended when needed for use, maintaining strength during operation while achieving compactness during storage or transport.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The headrest assembly offers improved comfort and adjustability, reduces weight, and provides a compact form factor while minimizing user contact with the connector, enhancing the massage experience.

AI summary
A headrest assembly (212) for supporting a face of a user (16) of a massage device (10) includes a resilient assembly (220) and a support arm assembly (222). The resilient assembly (220) supports the face (13) of the user. The support arm assembly (222) couples the resilient assembly (220) to the massage device (10). The support arm assembly (222) can include a first support arm (228) that selectively engages a headrest receiver assembly (15) of the massage device (10), a spaced apart second support arm (230) that selectively engages the headrest receiver assembly (15), and an arm connector (232) that couples the support arms (228) (230) together. The arm connector (232) can inhibit relative pivoting of the support arms (228) (230) when the support arms (228) (230) are not engaging the headrest receiver assembly (15).
