Solution Overview

Problem

Conventional height-adjustable workstations require significant space and are designed for single users, limiting flexibility and collaboration in office environments.

Innovation Solution

A work cell concept based on a tree-like structure with a height-adjustable trunk and rotatable working units, allowing for flexible attachment and detachment of components like tables, shelves, and screens, with electromechanical locking mechanisms for precise adjustment and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional height-adjustable workstations are used, then ergonomic adjustment capability is improved, but floor space requirement increases

Engineering Contradiction:
Improveergonomic adjustment capabilityVSAvoidfloor space requirement
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The work surface and support structure are nested within the column when not in use, allowing the entire workstation to be collapsed into a compact vertical form factor that occupies minimal floor space while maintaining full ergonomic adjustment functionality when deployed

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If conventional workstations are designed for single user, then user-specific ergonomic optimization is improved, but flexibility for collaboration deteriorates

Engineering Contradiction:
Improveuser-specific ergonomic optimizationVSAvoidflexibility for collaboration
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The column-based workstation is designed as a universal platform that can serve multiple users through adjustable height and rotatable work surfaces, enabling the same structure to be optimized for different users' ergonomic needs while also supporting collaborative configurations where multiple users can access the workspace

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Stability of the object's composition

If working units are fixed to column, then structural stability is improved, but flexibility for reconfiguration deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidflexibility for reconfiguration
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The joint elements incorporate locking mechanisms that enable the system to dynamically switch between locked (stable) and unlocked (mobile) states, allowing working units to be securely fixed during use for structural stability while enabling easy reconfiguration when needed

Inventive Principle:
Principle #15Dynamics

AI summary

The invention relates to a work cell, comprising a foot construction (10), a column (20) having a lower part (21) connected to the foot structure (10), and an upper part (22) that is height-adjustable with respect to the lower part (21). A first and a second support structure (30, 40) are mechanically connected to the upper part (22) of the column (20) by means of a first and a second articulated element (31, 41) in order to allow an axial rotation of the support structures (30, 40) about the column (20). At least one of the joint elements (31, 41) has a latching mechanism, which is designed to block a movement of the articulated element with respect to the column (20) in a normal state, and to release the movement of the articulated element in the event of an adjustment process initiated by a user of the work cell.
