Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable communication terminals face challenges in achieving a clean exterior design and improved aesthetic sense due to the visibility of coupling lines for light-transmitting portions, which complicates assembly and increases costs.
Innovation Solution
Integrally forming a light-diffusing portion on the main body housing using a Non-conductive Vacuum Metallization (NCVM) process, allowing for clean light emission and enhancing the exterior design and aesthetic appeal by eliminating the need for a separate light-transmitting member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light-transmitting portion is separately mounted along the side surface of the main body housing, then light can be emitted to the exterior of the portable communication terminal, but the exterior design becomes non-clean and the light-transmitting portion is visible when viewed from the exterior
Solution Approach 1:
The patent merges the light-transmitting portion with the main body housing by integrally forming the light-diffusing portion directly on the housing surface. This integration eliminates the separate mounting of the light-transmitting portion, making it indistinguishable from the housing when viewed from the exterior, thereby achieving a clean exterior design while maintaining light emission functionality.
2Illumination intensity
If a light-transmitting portion is separately mounted on the main body housing, then light transmission is enabled, but the assembly process becomes complex and fabrication costs increase
Solution Approach 1:
The patent combines the light-transmitting portion and main body housing into a single integrated structure through integral forming. This eliminates the need for separate mounting operations and coupling line processes, significantly simplifying the assembly process and reducing fabrication costs while maintaining light transmission capability.
3Illumination intensity
If a light-transmitting portion is separately mounted along the coupling line of the main body housing, then light can be transmitted to the exterior, but the coupling line becomes visible and degrades the sense of unity of the exterior
Solution Approach 1:
The patent integrates the light-diffusing portion directly onto the main body housing surface, eliminating the coupling line interface between separate components. This integration removes the visible coupling line from the exterior view, restoring the sense of unity and compositional stability of the device exterior while maintaining light transmission functionality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Simplifies the assembly process, reduces fabrication costs, and provides a unified, aesthetically pleasing exterior design by concealing the light-diffusing portion when not emitting light and enhancing light transmission through NCVM-coated surfaces during emission.
Implementation Method 1
applying a Non-conductive Vacuum Metallization (NCVM) process to a light-diffusing portion to be integrally formed on a main body housing

AI summary
A light-emitting device of a portable communication terminal improves exterior decoration by emitting light to the exterior of the portable communication terminal and implements a sense of unity of a design in a non-light emission state by integrating a portion to which the light is transmitted with a main body housing. The light-emitting device includes a housing, a light-emitting element for emitting light, a light guide sheet for guiding the light from the light-emitting element, and a light-transmitting portion integrally formed on the housing for transmitting the light from one end of the light guide sheet to an outer side of the housing. A sense of unity of the main body housing and the light-transmitting portion can be improved by applying a non-conductive vacuum metallizing (NCVM) process to the exterior. An aesthetic sense is improved with the sense of unity of the exterior design.
