Solution Overview

Problem

Existing workstations lack efficient and ergonomic solutions for loading grab trays and material boxes, leading to stressful movements, reduced productivity, and increased postural-related absences.

Innovation Solution

A carrier system with adjustable shelving and pivoting assemblies that allows for efficient loading from the rear, featuring aluminum strut profiles, sliding elements, and a height-adjustable design, enabling ergonomic positioning and flexible material access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional workstations are used without adjustable support systems, then the structure is simple and fixed, but employee strain increases and productivity decreases due to inefficient material access

Engineering Contradiction:
ImproveproductivityVSAvoidstructure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The support system incorporates adjustable height mechanisms and pivoting assemblies that allow dynamic reconfiguration of shelf positions and angles. This enables the workstation to adapt to different ergonomic requirements and material access patterns, thereby improving productivity without requiring complete structural redesign

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The support system is divided into modular components including multiple shelves, pivoting assemblies, and adjustable support structures. This segmentation allows independent adjustment of each component to optimize material access while maintaining overall structural integrity, balancing complexity with functional benefits

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If fixed shelving systems are used, then the device complexity is low, but the adaptability to individual ergonomic needs is poor

Engineering Contradiction:
Improveergonomic adaptabilityVSAvoidadjustment mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system employs height-adjustable shelves and pivoting assemblies that can be reconfigured to match individual employee ergonomic requirements. These dynamic adjustment capabilities enable the same support system to serve multiple users with different physical characteristics while maintaining manageable structural complexity through standardized adjustment mechanisms

Inventive Principle:
Principle #15Dynamics

3Productivity

If material storage is positioned between workstations, then material access is convenient, but space efficiency decreases when positioning multiple workstations adjacent to each other

Engineering Contradiction:
Improvematerial access efficiencyVSAvoidworkstation spacing
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The support system extends material storage vertically with multiple shelf levels and utilizes depth optimization to provide adequate storage capacity without increasing horizontal footprint. This dimensional approach allows multiple workstations to be positioned closely together while maintaining efficient material access through vertically arranged shelves and containers

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

4Loss of time

If restocking requires leaving the workstation, then the system is simple, but time loss increases and productivity decreases

Engineering Contradiction:
Improverestocking timeVSAvoidsupport system complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The support system incorporates pre-positioned shelves and storage locations for frequently used materials within easy reach of the workstation. This preliminary arrangement of materials allows employees to restock without leaving their work positions, reducing time loss while the modular shelf design keeps the added complexity manageable

Inventive Principle:
Principle #10Preliminary action

AI summary

The invention relates to an efficiently loadable carrier system and a shelving system (800) for an ergonomically adjustable workstation (100). The required position of the gripping containers can be determined by an individual person by moving the support profiles (11-13, 21-23). ​​This individual and simple adjustability allows each person to work ergonomically correctly and comfortably, even with different heights and arm lengths. By loading the gripping containers (42) in a direction dependent on the assembly sequence, either "from left to right" or vice versa, the assembly sequence can be specifically defined, thus preventing errors. The ergonomically required gripping lengths, reasonable gripping angles of the arms, and the effortless gripping process achieved through the use of gripping tongues (particularly gentle on the fingertips) prevent fatigue of the operator and increase performance, motivation, and quality.
