Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lifting chairs are complex in structure and lack a simple, 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 seat assembly, lifting assembly, and base assembly, featuring an elastic shielding cover that extends and retracts with the seat, providing both a lifting function and a simple, attractive appearance, with the elastic cover's upper and lower ends coupled to the seat and base assemblies, and a rotating mechanism allowing 360° rotation and elastic sleeve for posture regulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lifting chair is designed with a lifting assembly to enable height adjustment, then the lifting function is achieved, but the structure becomes complex and the appearance is less attractive
Solution Approach 1:
The patent uses an elastic shielding cover that acts as a flexible shell to wrap around and conceal the lifting assembly. This cover is made of elastic material that can stretch and retract, allowing it to hide the complex mechanical structure while maintaining a simple, smooth exterior appearance similar to traditional pier chairs.
Solution Approach 2:
The elastic shielding cover serves as an intermediary element between the lifting assembly and the external environment. It mediates the contradiction by providing a visual barrier that hides the complexity of the lifting mechanism while allowing the lifting function to operate underneath, thus presenting a simple appearance to observers.
2Adaptability or versatility
If a lifting assembly is added to a pier chair to enable height adjustment, then the adaptability for different body heights is improved, but the simple and attractive appearance of the pier chair is compromised
Solution Approach 1:
The elastic shielding cover is designed as a flexible shell that completely wraps around the lifting assembly, creating a smooth, continuous surface that resembles traditional pier chairs. The elastic material allows the cover to conform to the underlying structure while maintaining a clean, simple aesthetic appearance from the outside.
Solution Approach 2:
The elastic shielding cover copies the simple cylindrical appearance of traditional pier chairs while concealing the lifting mechanism underneath. It replicates the external form factor and visual characteristics of pier chairs, allowing the new lifting function to be integrated without compromising the iconic simple appearance that users expect.
3Shape
If the elastic shielding cover is designed to always remain in a tensioned state during lifting, then the appearance remains attractive with a narrow waist part, but the structure requires continuous tension maintenance
Solution Approach 1:
The elastic shielding cover utilizes dynamic elasticity to maintain its tensioned state. The elastic material naturally provides restoring forces that keep the cover taut during lifting and lowering movements, creating the narrow waist appearance dynamically as the chair transitions between positions rather than requiring a static tensioning mechanism.
Solution Approach 2:
The elastic shielding cover is self-tensioning through its inherent elastic properties. The material's elasticity automatically maintains the tensioned state and creates the narrow waist appearance without requiring external tensioning mechanisms or additional components, as the elastic recovery force self-regulates the cover's tension during movement.
