Solution Overview

Problem

Industrial design specifications for server panel lights often result in lighting inconsistencies across different server versions due to hardware component variations, leading to non-uniform color and brightness, which becomes noticeable when servers are stacked together.

Innovation Solution

The implementation of light adjustment circuitry within servers that dynamically adjusts the color of panel LEDs based on detected hardware configurations and server versions, using pulse width modulation to account for lighting variance characteristics, allowing for uniformity without physical changes to hardware components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If hardware components are standardized across server versions, then manufacturing complexity is reduced, but lighting consistency deteriorates due to component variations

Engineering Contradiction:

Improvehardware component varietyVSAvoidlighting consistency

Core Design Contradiction:

Device complexityVSIllumination intensity

Solution Approach 1:

The patent adjusts the electrical parameters (current, voltage, pulse width) of the LED driver circuit to compensate for variations in LED components across different server versions. By dynamically changing these parameters, the system maintains consistent light output characteristics without requiring hardware standardization.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent replaces physical hardware standardization (mechanical approach) with electronic parameter adjustment (electrical approach). Instead of ensuring identical LED components across server versions, the system uses software-controlled electrical parameters to achieve lighting consistency.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Illumination intensity

If separate hardware components are used for each server version, then lighting consistency is improved, but supply chain complexity and production cost increase

Engineering Contradiction:

Solution Approach 1:

The patent creates a universal LED driver circuit design that can accommodate multiple server versions and LED variations through software control. This single hardware design serves multiple functions across different server platforms, eliminating the need for version-specific components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system uses adjustable electrical parameters in the LED driver to adapt to different server versions. This parameter-based approach allows one hardware design to serve multiple purposes, reducing supply chain complexity while maintaining lighting uniformity.

Solution Approach 1:

The patent replaces physical hardware modifications with electronic parameter adjustments. Instead of physically changing LED components or their mounting structures across server versions, the system uses software-controlled electrical parameters to achieve color uniformity, significantly reducing production steps and time.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses a standardized LED driver circuit design that can be copied and applied across all server versions. This template-based approach eliminates the need for custom hardware modifications for each server version, streamlining production while maintaining lighting consistency.
