Reclining Rocking Chair Motion Synchronization for Relaxation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing relaxation apparatuses often experience awkward motion feels due to independent tilting and rocking motions, which can offset each other, leading to ineffective relaxation effects.
Innovation Solution
A relaxation apparatus with a body support system that includes a rocker drive and a control mechanism to synchronize rocking and tilting motions by adjusting the angle between the seat and connected supporter, allowing cooperative movement between the two to enhance relaxation effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the backrest tilting motion and body support rocking motion are performed independently, then each motion can be controlled separately, but the motions may offset each other causing awkward motion feel and reducing relaxation effect
Solution Approach 1:
The patent combines the backrest tilting motion and body support rocking motion into a synchronized cooperative motion. The control unit coordinates both motions so that they work together synergistically rather than independently, ensuring that the tilting and rocking motions complement each other to produce an effective relaxation effect without offsetting.
2Reliability
If the angle between seat and connected supporter is adjusted to change body support position, then the relaxation effect is enhanced through cooperative motion, but the device complexity increases
Solution Approach 1:
The connected supporter serves multiple functions: it supports the user's body, acts as a backrest that can tilt, and functions as a position adjustment mechanism. By making the connected supporter multi-functional, the patent avoids adding separate complex mechanisms for each function, thereby reducing overall device complexity while still achieving enhanced relaxation effects through coordinated motion.
3Adaptability or versatility
If the body support means is moved between basic position, sleep position, and upright position, then adaptability to different user needs is improved, but the device complexity increases
Solution Approach 1:
The same connected supporter structure performs multiple positions (basic, sleep, and upright positions) through coordinated tilting and rocking motions. This multi-functional design allows the system to achieve high adaptability without requiring separate mechanisms for each position, thereby controlling device complexity.
Solution Approach 2:
The system uses dynamic, coordinated motion between tilting and rocking to achieve different positions rather than static mechanical adjustments. The control unit dynamically adjusts the angles and timing of both motions to transition between positions, providing versatility through software-controlled dynamics rather than complex mechanical switches or locks.

AI summary
OBJECT A relaxation apparatus that rocks and moves a body and tilts a body support means to generate an effective relaxation effect. SOLUTION A reclining mechanism 33, which serves as a position adjustment means, increases the angle between a backrest 31 and a seat 30 from a basic position to a sleep position when a body support 13 is moving toward the front. Further, the reclining mechanism 33 decreases the angle between the backrest 13 and the seat 30 from the sleep position to the basic position when the body support 13 is moving toward the rear.
