Solution Overview

Problem

Existing seat devices require complex structural designs for seat mechanisms to enable rotating and pivoting movements, which can lead to uncomfortable tilting and unintentional tipping, especially in designs without a defined pivoting path.

Innovation Solution

A combined rotating and pivoting device is positioned near the standing surface, allowing the seat and support elements to pivot without a separate seat mechanism, featuring a base body that rotates and a pivoting head that moves on a circular arc path below the standing surface, ensuring a flat pivoting motion and preventing sharp tilting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a seat mechanism is arranged between the seat element and support element to enable rotating and pivoting movements, then the seat element can be rotated and pivoted, but the structural design becomes complicated

Engineering Contradiction:
Improverotating and pivoting capabilityVSAvoidseat mechanism structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the rotating and pivoting functionality from the traditional seat mechanism location (between seat element and support element) and relocates it to the standing element near the standing surface. This separation eliminates the need for a complex seat mechanism while preserving the desired movement capabilities.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a new spatial dimension for the rotating and pivoting mechanism by positioning it at the standing element rather than at the seat element. This dimensional relocation allows the mechanism to operate independently from the seat structure, simplifying the overall design.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If the seat element is enabled to pivot without a defined pivoting path, then the structure is simplified, but unintentional tipping and uncomfortable tilting occur

Engineering Contradiction:
Improveseat mechanism structureVSAvoidstability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent introduces a guide structure as an intermediary component that defines the pivoting path. This guide structure ensures that the seat element follows a predetermined safe trajectory during pivoting, preventing unwanted tilting and tipping while maintaining structural simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent pre-defines the pivoting path through the guide structure before the pivoting action occurs. This preliminary configuration ensures that the seat element can only pivot along a safe, controlled trajectory, preventing instability issues before they can occur.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If a combined rotating and pivoting device is arranged remotely from the seat element near the standing surface, then the seat mechanism structure is simplified, but the pivoting path must be carefully controlled

Engineering Contradiction:
Improveseat mechanism structureVSAvoidpivoting path definition
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The guide structure serves as an intermediary that translates the remote rotating and pivoting movements into a controlled, predefined path for the seat element. This intermediary component handles the precision requirement by providing physical guidance rather than relying on precise manufacturing tolerances throughout the entire mechanism.

Inventive Principle:
Principle #24Intermediary (Mediator)
