Solution Overview

Problem

Existing shelving systems face complexity and high effort in supplying power and data to terminal devices, especially when converting layouts to accommodate different-sized goods, due to cumbersome cable management and assignment of information in cable-supported solutions.

Innovation Solution

A multi-layer supply element with at least three conductor tracks is integrated into the hollow shelf post, allowing for simple and efficient power and data distribution to terminal devices, with freely accessible sections on the surface for easy connection, and can be rearranged without extensive cable re-laying.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cable-supported solutions are used to supply power and data to terminal devices, then power and data can be transmitted reliably, but the system complexity and effort for cable management and reconfiguration increase significantly

Engineering Contradiction:
Improvepower and data transmissionVSAvoidcable management complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the power and data supply function from external cables and integrates it into the shelf post structure itself. The supply element is embedded within the hollow shelf post, eliminating the need for separate cable routing and management systems while maintaining reliable power and data transmission to terminal devices.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The shelf post is designed to serve multiple functions: it provides structural support for shelves and simultaneously integrates the supply element for power and data distribution. This multi-functional design eliminates the need for separate cable infrastructure, reducing system complexity while maintaining transmission reliability.

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

2Reliability

If cable-supported solutions are used for power and data supply, then terminal devices can be powered reliably, but the effort and cost for re-laying cables during system conversion increase

Engineering Contradiction:
Improvepower supply reliabilityVSAvoidsystem conversion ease
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The supply element is designed with modular conductor tracks that can be independently accessed and connected at different heights along the shelf post. This segmentation allows individual terminal devices to be connected or disconnected without affecting other connections, enabling easy system conversion and reconfiguration while maintaining reliable power supply.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic accessibility of conductor tracks through opening elements that can be selectively opened at different positions along the shelf post. This allows the system to adapt to changing requirements during conversion, enabling easy reconfiguration of power and data connections without extensive re-laying work.

Inventive Principle:
Principle #15Dynamics

3Loss of information

If specific information assignment to specific terminals is required, then data can be accurately delivered, but the complexity of cable assignment and connection management increases

Engineering Contradiction:
Improvedata assignment accuracyVSAvoidconnection management complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical cable routing and assignment systems with an integrated electrical connection system. The conductor tracks are positioned and configured to automatically establish correct connections between the supply element and terminal devices based on their spatial positions, eliminating the need for manual cable assignment and management while ensuring accurate data delivery.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Adaptability or versatility

If the distance between shelving brackets is changed to accommodate different goods, then the shelving system becomes more versatile, but extensive cable re-laying is required in cable-supported solutions

Engineering Contradiction:
Improveshelf configuration flexibilityVSAvoidcable re-laying time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The supply element is pre-installed within the shelf post structure with conductor tracks available at multiple predetermined positions. This preliminary preparation allows shelf brackets to be moved to different distances and configurations without requiring subsequent cable re-laying, as the power and data connections are already in place and can be easily accessed at the new positions.

Inventive Principle:
Principle #10Preliminary action
