Solution Overview
Problem
Current lifting chairs are complex in structure and lack a simple and attractive appearance, while modern pier chairs lack a lifting function, making them less applicable for individuals with varying body heights.
Innovation Solution
A lifting seating device with a simple and attractive appearance, featuring a seat assembly, lifting assembly, and base assembly, where an elastic shielding cover is coupled to both ends, extending and retracting with the lifting action to cover the base assembly and provide a lifting function, utilizing elastic materials like rubber, plastic, or fabric for the cover and snap teeth for secure mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lifting chair is designed with a lifting function, then it provides adaptability for different body heights, but the structure becomes complex and appearance becomes less attractive
Solution Approach 1:
The patent uses an elastic fabric cover as a flexible shell that envelops the lifting mechanism and seat assembly. This elastic cover hides the complex mechanical structure while maintaining a simple, attractive appearance similar to pier chairs. The fabric stretchability allows it to accommodate the lifting and lowering movements without requiring additional external structures.
2Adaptability or versatility
If a lifting chair is designed with a lifting function, then it provides adaptability for different body heights, but the structure becomes complex
Solution Approach 1:
The patent merges the elastic fabric cover with the lifting mechanism by directly coupling the cover to the lifting assembly and seat assembly. This integration eliminates the need for separate protective housings or additional structural elements, simplifying the overall device while maintaining the lifting function.
3Shape
If an elastic shielding cover is used to cover the base assembly and lifting assembly, then appearance becomes simple and attractive, but the cover must extend and retract during lifting
Solution Approach 1:
The elastic fabric cover serves as a flexible shell that naturally extends and retracts through its material properties. The cover is coupled to both the seat assembly and base assembly, allowing it to accommodate vertical movements during lifting without requiring mechanical extension mechanisms.
Solution Approach 2:
The patent employs a dynamic cover solution where the elastic fabric continuously adjusts its shape and length in response to the lifting and lowering actions. The cover transitions from a static appearance to a dynamic structure that adapts to the changing dimensions of the assembled components.
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 achieves a balanced appearance and functionality, allowing 360° rotation and posture regulation with an elastic restoring force, ensuring suitability for different users and maintaining an attractive appearance during lifting and lowering.
Implementation Method 1
the elastic shielding cover extends and retracts with the lifting of the seat assembly under the action of the lifting assembly. The elastic shielding cover is always in a tensioned state when extending and retracting

AI summary
The present invention relates to a lifting seating device, including a seat assembly, a lifting assembly and a base assembly which can be placed on the ground. A lower end of the lifting assembly is mounted to the base assembly, and an upper end of the lifting assembly is connected to the seat assembly. The lifting seating device further includes an elastic shielding cover arranged to circle a side surface of the lifting seating device. Upper and lower ends of the elastic shielding cover are respectively coupled to the seat assembly and the base assembly. The elastic shielding cover extends and retracts with the lifting of the seat assembly under the action of the lifting assembly. The lifting assembly is arranged between the seat assembly and the base assembly, the elastic shielding cover is arranged, and upper and lower ends of the elastic shielding cover are respectively coupled to the seat assembly and the base assembly. Thus, the base assembly and the lifting assembly are covered by the elastic shielding cover to achieve a simple and attractive appearance. Meanwhile, the elastic shielding cover extends and retracts with the lifting of the seat assembly under the action of the lifting assembly, so that a chair also has a lifting function.
