Solution Overview

Problem

Conventional power cables and adaptors are visually conspicuous, detracting from the aesthetic appeal of electronic devices and interfering with their design, especially when exposed, as they are typically black or brightly colored and not designed to match modern, slimmed-down electronic device designs.

Innovation Solution

A power cable with conducting wires arranged in parallel and coated with a transparent material, featuring transparent electrodes with metal ends, and a power adaptor with a configuration that includes AC/DC conversion, main and standby voltage suppliers, and a switching unit to manage power modes, all integrated with a transparent DC cable that minimizes visibility by transmitting light.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a power cable uses a thick insulating outer coating of black or primary color, then electrical insulation and safety are improved, but the cable becomes visually conspicuous and deteriorates the overall appearance of the electronic device

Engineering Contradiction:
Improveelectrical insulationVSAvoidvisual appearance
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The patent applies the color change principle by transitioning from traditional black or primary color coatings to transparent or translucent coatings. This allows the cable to maintain its insulating properties while becoming visually inconspicuous, effectively changing its optical appearance from opaque to transparent to blend with the background or match the electronic device aesthetics.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent employs composite materials by combining transparent coating layers with metallic shielding layers and insulating materials. The transparent coating serves both aesthetic purposes and protective functions, while the metallic shielding provides electromagnetic interference protection, creating a multi-functional composite structure that addresses both appearance and reliability requirements.

Inventive Principle:
Principle #40Composite materials

2Shape

If a power cable uses a transparent material coating, then the cable becomes invisible and matches the electronic device design, but the manufacturing complexity increases due to the need for transparent electrodes with metal ends

Engineering Contradiction:
Improvevisual appearanceVSAvoidmanufacturing complexity
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the conducting wire structure into distinct segments: transparent electrode portions and metal end portions. This segmentation allows each part to serve its specific function - the transparent portions maintain visibility while the metal ends provide reliable electrical connections, simplifying the overall manufacturing process by treating different sections separately with appropriate materials and methods.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements local quality by applying different material properties to different locations of the cable. The transparent coating is applied where visual inconspicuousness is needed, while metal ends are applied at connection points where electrical conductivity and mechanical strength are critical. This localized application of different material qualities optimizes both appearance and functionality without unnecessarily complicating the entire cable structure.

Inventive Principle:
Principle #3Local quality

3Shape

If the power cable is made transparent, then it transmits light and becomes nearly invisible, but the structural integrity and protection of conducting wires may be compromised

Engineering Contradiction:
ImprovetransparencyVSAvoidstructural integrity
Core Design Contradiction:
ShapeVSStrength

Solution Approach 1:

The patent uses composite materials to combine the optical properties of transparent coatings with the mechanical strength of metallic shielding layers and robust insulating materials. This multi-layer composite structure ensures that while the outer appearance remains transparent and aesthetically pleasing, the internal structure maintains sufficient strength and protection for the conducting wires throughout the cable's service life.

Inventive Principle:
Principle #40Composite materials
