Solution Overview

Problem

In complex data technology networks, identifying and locating devices for troubleshooting or maintenance is difficult due to their standardized appearance and the need for physical access, which requires significant operational effort, especially when multiple devices need to be recognized.

Innovation Solution

A central device and system that uses different data technology protocols to generate and transmit control signals to subscriber devices, enabling them to output user-friendly identification signals such as light or sound, allowing for easy localization without additional equipment, and facilitating efficient operation by mediating between protocol levels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If devices are connected in complex networks with standardized appearance, then network functionality and connectivity are improved, but device identification and localization become difficult requiring significant operational effort

Engineering Contradiction:
Improvenetwork connectivityVSAvoiddevice identification
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies visual signaling through light sources (LEDs) that emit different colors or patterns to indicate device identity, status, and location. This allows operators to quickly identify specific devices in complex networks without physical inspection, resolving the contradiction between network complexity and ease of device identification.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent introduces an intermediary identification system that mediates between the network infrastructure and human operators. This system translates device metadata (location, type, status) into human-perceptible visual signals, enabling easy device identification without requiring direct physical access or technical expertise.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of repair

If physical location of devices is required for troubleshooting and maintenance, then device accessibility is improved, but operational effort and time consumption increase significantly

Engineering Contradiction:
Improvedevice accessibilityVSAvoidtime to locate device
Core Design Contradiction:
Ease of repairVSLoss of time

Solution Approach 1:

The patent implements preliminary visual identification signaling that allows operators to locate devices before physical access is needed. By displaying device location and status information through light sources, the system enables operators to navigate directly to the correct device, eliminating time-wandering and unnecessary physical inspections.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces mechanical/physical device identification methods (manual inspection, physical tags) with optical signaling systems. This substitution allows remote identification and localization of devices without requiring physical proximity or manual searching, significantly reducing time loss while maintaining ease of repair.

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

3Difficulty of detecting and measuring

If additional equipment is used for device identification, then identification capability is improved, but system complexity and cost increase

Engineering Contradiction:
Improvedevice detectabilityVSAvoidsystem complexity
Core Design Contradiction:
Difficulty of detecting and measuringVSDevice complexity

Solution Approach 1:

The patent integrates identification functionality into existing network devices using multi-functional components. Light sources originally intended for status indication are repurposed or augmented to provide location and identification information, eliminating the need for separate identification equipment and reducing overall system complexity.

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

Solution Approach 2:

The patent enables devices to self-identify through built-in light sources that automatically display device information. This self-service identification capability eliminates the need for external identification equipment or manual tagging, reducing system complexity while improving device detectability.

Inventive Principle:
Principle #25Self-service
