Segmented Massage Chair Guide Rail with Hinged Tracks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional massage chairs experience disconnection between support and seat tracks, preventing simultaneous back and leg massages due to defined distance between massaging mechanisms, resulting in inability to massage users effectively when sitting or lying down.
Innovation Solution
A segmented guide rail system with connected seat and support tracks using hinge elements and connection shafts, allowing the massaging mechanism to move back and forth on a connection track, enabling rotation at different angles for successive massage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a distance is defined between the seat track and the support track to avoid interference, then the two massaging mechanisms can operate independently, but the support track and seat track become disconnected and cannot move back and forth together
Solution Approach 1:
The support track is divided into multiple segments (first support track segment, second support track segment) that can rotate relative to each other around a connection shaft. This segmentation allows the track to flex and maintain connection while accommodating the movement of massaging mechanisms independently, resolving the contradiction between independent operation and continuous connection.
Solution Approach 2:
The support track segments are designed to rotate dynamically around the connection shaft, transforming from a static rigid structure to a dynamic articulated structure. This allows the track to adapt its configuration during operation, maintaining connection between seat track and support track while enabling independent movement of massaging mechanisms.
2Adaptability or versatility
If the massaging mechanism is positioned to massage both back and leg, then comprehensive massage coverage is achieved, but the mechanism cannot move back and forth on connected tracks due to disconnection
Solution Approach 1:
Dividing the support track into rotatable segments enables the massaging mechanism to traverse the entire length of the combined seat and support tracks without interruption, maintaining ease of operation while achieving comprehensive massage coverage across different body regions.
Solution Approach 2:
The connection shaft and hinge elements create a universal joint system that allows the massaging mechanism to operate along a continuous path that serves multiple functions: massaging both the back and leg regions, and accommodating different user positions, thereby achieving versatility without compromising operational ease.
3Productivity
If the support track and seat track are connected to form a continuous track, then the massaging mechanism can move back and forth continuously, but the two massaging mechanisms may interfere with each other
Solution Approach 1:
The dynamic rotation capability of the support track segments around the connection shaft allows the system to continuously move the massaging mechanism along the entire track length while the mechanisms can independently adjust their positions and orientations, preventing interference while maintaining continuous productivity.
Solution Approach 2:
The articulated structure enables changes in the geometric parameters (angles, positions) of the support track segments relative to the seat track, allowing the system to maintain continuous track connectivity while adjusting the spatial relationship between massaging mechanisms to prevent interference during operation.

AI summary
A segmented guide rail of a massage chair contains: a seat track and a support track. The seat track includes a first coupling segment formed on an end thereof, and the support track includes a second coupling segment formed on an end thereof. The first segment and the second segment are connected by two hinge elements, and the seat track and the support track are connected to form at least one connection track on which a massaging mechanism of the massage chair is driven to move back and forth. Thereby, the massaging mechanism of the massage chair moves back and forth, when the support frame rotates to different angles, thus massaging the user in different postures successively.
