Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional beds, chairs, and sofas often have stationary configurations or limited swinging directions, leading to user boredom and discomfort due to monotone motions and excessive inclined angles, which can cause fatigue and unease.
Innovation Solution
A base seat design featuring a fixation base, first and second rocking mounts, and drive devices allowing for multi-directional swinging with variable inclined angles, enabling the base seat to swing in any direction and adjust its angle dynamically to prevent monotony and promote relaxation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional rocking chairs are designed to swing back and forth, then the chair provides a swinging function, but the single direction causes user boredom and fatigue
Solution Approach 1:
The base seat is divided into multiple independent rocking mounts (first rocking mount and second rocking mount) that can swing in different directions. Each rocking mount functions as an independent module, allowing the overall structure to achieve multi-directional swinging capability while maintaining manageable complexity through modular design
Solution Approach 2:
The base seat structure is designed to perform multiple swinging functions simultaneously - the first rocking mount provides left-right swinging while the second rocking mount provides forward-backward swinging. This multi-functional design allows a single base seat to offer universal directional swinging without requiring separate structures for each function
2Ease of operation
If conventional rocking chairs have a fixed inclined angle during swinging, then the structure is simple, but users feel uneasy and uncomfortable
Solution Approach 1:
The suspension arms are designed with asymmetric pivot distances (top ends closer together than bottom ends) to create variable inclined angles during swinging motion. This dynamic adjustment of the inclined angle adapts to different phases of the swinging cycle, providing optimal comfort at different positions while maintaining a relatively simple structural configuration
Solution Approach 2:
The suspension arms are configured with asymmetric geometry where the distance between top ends is smaller than the distance between bottom ends. This asymmetric design naturally produces variable inclined angles during swinging without requiring additional adjustment mechanisms, achieving comfort optimization through geometric design rather than complex mechanical systems
3Adaptability or versatility
If the base seat allows multi-directional swinging with variable inclined angles, then user comfort is improved, but the structure becomes more complex
Solution Approach 1:
The second rocking mount is positioned on top of the first rocking mount, creating a nested configuration where one rocking mechanism is integrated within another. This nesting allows the base seat to achieve multi-directional swinging capability while compactly organizing the structural components, reducing overall complexity compared to separate independent structures
Solution Approach 2:
Multiple rocking functions are merged into a single integrated base seat structure. The first and second rocking mounts are combined in one assembly, with the second rocking mount utilizing the motion of the first rocking mount. This merging achieves universal directional swinging without requiring separate structures for each swinging function
Applied Scientific Principles
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 base seat effectively prevents user fatigue and boredom by allowing universal direction swinging and varying inclined angles, enhancing user comfort and relaxation, while maintaining stability and smooth operation.
Implementation Method 1
each of the two front suspension arms has a top end pivotally connected with the front frame body and a bottom end pivotally connected with the first rocking mount
Implementation Method 2
the first rocking mount is swingable leftward and rightward relative to the fixation base along a first arc path with a variable inclined angle thereof

AI summary
A base seat for a bed, chair or sofa includes a fixation base, first and second rocking mounts, four arms pivotally connected between the fixation base and the first rocking mount such that a distance between top ends of each paired arms is smaller than a distance between bottom ends of the paired arms, and another four arms pivotally connected between the first and second rocking mounts such that a distance between top ends of each paired arms is smaller than a distance between bottom ends of the paired arms. First and second drive devices respectively drive the first and second rocking mounts to swing leftward and rightward relative to the fixation base and forward and backward relative to the first rocking mount along first and second arc paths with variable inclined angles, such that the base seat has a multidirectional swinging function with desired inclined angles during swinging.
