Solution Overview
Problem
Prolonged sitting in chairs leads to discomfort and health issues due to maintained posture, necessitating a solution for flexible and comfortable posture changes.
Innovation Solution
A swing chassis device with a base, first and second swing seats, and elastic buffer members, allowing the seats to swing left and right and back and forth, enhancing flexibility and comfort through adjustable sitting postures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed chair structure is used, then manufacturing simplicity is maintained, but user comfort and posture flexibility deteriorate due to prolonged static sitting
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed chair structure into a dynamic system with multiple swing seats that can move independently. The first swing seat swings left and right relative to the base, while the second swing seat swings back and forth relative to the first swing seat, creating a dynamic sitting experience that adapts to user needs and reduces fatigue from prolonged static sitting
Solution Approach 2:
The patent segments the chair chassis into multiple independent movable components: a base, a first swing seat hinged to the base, and a second swing seat hinged to the first swing seat. This segmentation allows each component to move independently, providing multiple degrees of freedom and enhancing posture flexibility without requiring complete redesign of the entire chair structure
2Adaptability or versatility
If multiple swing mechanisms are added to increase posture flexibility, then sitting comfort is improved, but structural complexity increases
Solution Approach 1:
The patent merges multiple swing mechanisms into a unified chassis structure where the first and second swing seats are integrated through hinged connections. The elastic buffer members are also integrated into the structure to provide cushioning. This merging approach achieves complex motion capabilities while maintaining structural coherence and avoiding excessive component proliferation
3Ease of operation
If elastic buffer members are added to provide cushioning, then sitting comfort is enhanced, but device complexity increases
Solution Approach 1:
The elastic buffer members are strategically positioned to automatically provide cushioning and support during the swinging motion. The buffers engage and disengage based on the motion state of the swing seats, providing comfort enhancement without requiring active control systems or complex mechanisms. The structure itself serves the cushioning function through the inherent elasticity of the buffer members
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 device provides increased flexibility in sitting postures, reducing fatigue and discomfort by allowing users to change their sitting positions freely, thereby improving comfort and health outcomes.
Implementation Method 1
An elastic buffer member for providing buffering and a restoring force is disposed between the first swing seat and the base

AI summary
A swing chassis device includes a base, a first swing seat, and a second swing seat. The first swing seat is hinged onto the base through a first rotating shaft. The second swing seat is hinged onto the first swing seat through a second rotating shaft. The second swing seat can swing back and forth. The first swing seat can drive the second swing seat to swing left and right together. Further, an elastic buffer member is disposed between the first swing seat and the base. The base is configured to be connected a chair leg air rod. Under the action of the first swing seat, the first swing seat can swing left and right on the base, and the second swing seat can swing back and forth on the first swing seat and can swing left and right together with the first swing seat under the driving of the first swing seat.
