Solution Overview

Problem

Existing seat devices require complex structural designs for rotary and pivoting movements, often necessitating a functional seat mechanism between the seat and support elements, which can complicate the design and functionality.

Innovation Solution

A combined turning and pivoting device is positioned remotely from the seat element, near the standing surface, connecting the stand and support elements, allowing for defined rotary and pivoting movements without a seat mechanism between the seat and support elements, utilizing a spring element to influence pivoting resistance and ensuring pivoting only in a single direction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

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

Engineering Contradiction:

Improverotary and pivoting movement capabilityVSAvoidstructural design complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the turning and pivoting functionality from the traditional seat mechanism location (between seat element and support element) and relocates it to the stand element. This separation eliminates the need for a complex functional seat mechanism while preserving the desired movement capabilities of the seat assembly.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of placing the turning and pivoting mechanism at the upper position (between seat and support), the invention inverts the arrangement by positioning the mechanism at the lower position (in the stand element). This inversion simplifies the overall structure while achieving the same functional outcome.

Inventive Principle:

Principle #13The other way round (Inversion)

2Device complexity

If the turning and pivoting device is arranged near the standing surface, then the design is simplified, but the seat assembly may become unstable

Engineering Contradiction:

Improvestructural design simplicityVSAvoidseat assembly stability

Core Design Contradiction:

Device complexityVSStability of the object's composition

Solution Approach 1:

The spring element acts as a counterbalancing mechanism that provides resistance to pivoting movements. This spring-based counterweight system stabilizes the seat assembly by controlling the pivoting motion, preventing excessive or unintended movements while maintaining the simplified lower-positioned mechanism design.

Inventive Principle:

Principle #8Anti-weight (Counterweight)

3Device complexity

If the seat element is rotated and pivoted as a unit with the support element, then the design is simplified, but control over individual movements is reduced

Engineering Contradiction:

Improvemechanism structure simplicityVSAvoidmovement control precision

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The mechanism dynamically separates rotation and pivoting into two independent degrees of freedom. The first bearing enables rotation about a vertical axis, while the second bearing enables pivoting about a horizontal axis. This dynamic separation allows the seat assembly to perform combined movements while maintaining structural simplicity in the mechanism design.

Inventive Principle:

Principle #15Dynamics

AI summary

The invention relates to a seat arrangement (1). In order to provide a seat arrangement (1) in which a defined rotary and pivoting movement of the seat element (2, 3) is possible without there being any need for a functional seat-mechanism unit to be arranged between the seat element (2, 3) and supporting element (4), the invention proposes a combined rotary and pivoting device (6) for rotating and pivoting a subassembly (5) of the seat arrangement (1), which subassembly (5) comprises a seat element (2, 3), wherein the rotary and pivoting device (6) is arranged at a distance from the seat element (2, 3) of the seat arrangement (1), in the vicinity of a standing surface (7) of the seat arrangement (1), and is designed such that, irrespective of the rotary position of the subassembly (5), a pivoting movement of the subassembly (5) is only ever possible in a single direction (23) in relation to said subassembly (5).
