RGB Light Module Sandwich Layer Mobile Phone Case
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile phone cases with RGB light modules are limited by a single light-emitting region, often on one side, which restricts the area of illumination and makes it difficult for users to perceive light when the phone is placed face up, as light from a back-mounted light-emitting member is not easily visible.
Innovation Solution
A mobile phone case with RGB light module featuring a sandwich layer containing a PCB board, light-emitting members, and a signal transceiver, where light-emitting members are positioned on both the back and side, with the signal transceiver connected to the mobile phone to control light-emitting modes, utilizing LED lights and light guide plates for area illumination, and a magnetic region for wireless charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the light-emitting region is provided only on one side of the mobile phone case, then the structure is simple, but the light-emitting area is limited and visibility is poor
Solution Approach 1:
The light-emitting members are segmented into two distinct groups: one group arranged on the side surface of the mobile phone case and another group arranged on the back surface. This segmentation allows the light-emitting area to be expanded across multiple surfaces while maintaining a modular structure that manages complexity through organized distribution of light-emitting components.
Solution Approach 2:
The light-emitting members transition from being confined to a single two-dimensional plane (one side) to being distributed across multiple surfaces (side and back), effectively utilizing three-dimensional space. This dimensional expansion increases the total light-emitting area while the structured arrangement manages the complexity of the multi-surface configuration.
2Illumination intensity
If the light-emitting region is provided on the back of the mobile phone case, then the light-emitting area is increased, but the light emitted cannot be easily perceived when the phone is placed face up
Solution Approach 1:
The light-emitting members are segmented into side-arranged members and back-arranged members, each serving distinct visibility functions. The side-arranged members provide visibility when the phone is placed face up on a plane, while the back-arranged members enhance visibility when the phone is held or viewed from the back, thereby improving overall light perception across different usage scenarios.
Solution Approach 2:
Different regions of the mobile phone case are assigned different light-emitting qualities: the side surface receives light-emitting members optimized for lateral visibility when the phone is flat, while the back surface receives light-emitting members optimized for rear visibility. This local differentiation ensures that each area contributes to visibility in its specific context, improving overall perception ease.
3Illumination intensity
If multiple light-emitting members are arranged on both side and back, then the visibility and lighting effect are improved, but the device complexity increases
Solution Approach 1:
The light-emitting members serve multiple functions: they provide illumination for visibility when the phone is placed face up (side-arranged members), enhance lighting effect when held or viewed from different angles (back-arranged members), and can be controlled through the signal transceiver for various lighting modes. This multi-functionality justifies the increased component complexity by delivering enhanced lighting effects and visibility across multiple usage scenarios.
Solution Approach 2:
The signal transceiver receives control signals from the mobile phone and provides feedback control to the light-emitting members, enabling various lighting modes and patterns. This feedback mechanism manages the complexity of multiple light-emitting members by providing centralized control, allowing the system to coordinate the numerous components through programmable lighting sequences and patterns.
