Problem

Existing electrical components, such as USB ports, power plugs, and control elements, are difficult to identify and operate in unfavorable lighting conditions, leading to challenges in precise alignment and operation.

Innovation Solution

Incorporating fluorescent or phosphorescent materials into the visible surfaces of electrical components, such as USB ports, power plug pins, and component covers, to enhance visibility and orientation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If conventional materials are used for electrical components, then manufacturing cost and simplicity are maintained, but visibility and recognizability in poor lighting conditions deteriorate

Engineering Contradiction:
Improvevisibility in poor lightingVSAvoidmaterial composition complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The patent applies composite materials by combining conventional plastic or metal materials with fluorescent or phosphorescent materials to create electrical components that emit light in darkness. This composite approach maintains the structural integrity and electrical functionality of the base material while adding the light-emitting property, thereby improving visibility without completely replacing the original material system.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent implements local quality by applying fluorescent or phosphorescent materials selectively to specific surface portions of electrical components rather than the entire component. This allows the critical areas (such as contact surfaces, identification marks, or user interaction zones) to emit light for enhanced visibility, while other areas maintain their original material properties and manufacturing simplicity.

Inventive Principle:
Principle #3Local quality

2Ease of operation

If fluorescent or phosphorescent materials are added to electrical components, then visibility and orientation are improved, but manufacturing complexity increases

Engineering Contradiction:
Improvealignment precisionVSAvoidmanufacturing process complexity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent applies fluorescent or phosphorescent materials selectively to specific surface portions of electrical components rather than the entire component. This allows the critical areas (such as contact surfaces, identification marks, or user interaction zones) to emit light for enhanced visibility, while other areas maintain their original material properties and manufacturing simplicity.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent implements partial action by applying the light-emitting material only to the extent necessary for improving visibility and alignment - specifically to surface portions that are visible in the plug-in slot or critical for user orientation. This partial application avoids the complexity of treating entire components, thereby balancing manufacturing ease with operational improvement.

Inventive Principle:
Principle #16Partial or excessive action

3Illumination intensity

If uniform material composition is used throughout electrical components, then manufacturing simplicity is maintained, but visibility enhancement is insufficient

Engineering Contradiction:
Improvevisibility enhancementVSAvoidmaterial distribution complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The patent applies fluorescent or phosphorescent materials selectively to specific surface portions of electrical components rather than the entire component. This allows the critical areas (such as contact surfaces, identification marks, or user interaction zones) to emit light for enhanced visibility, while other areas maintain their original material properties and manufacturing simplicity.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent segments the material composition of the electrical component into different regions: areas with fluorescent/phosphorescent materials for visibility enhancement and areas with conventional materials for structural functionality. This segmentation allows targeted visibility improvement without requiring the entire component to be made of complex composite materials.

Inventive Principle:
Principle #1Segmentation

AI summary

The present invention relates to a component of an electrical connector with a plug-in slot, wherein a plastic element is located inside the plug-in slot. To improve the user's orientation when operating controls or for contacting, even in poor lighting conditions, the invention proposes that at least those surface portions of the plastic element that are visible in the plug-in slot before contacting the connector be made of a material with fluorescent or phosphorescent properties.
