Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display cradle technologies fail to efficiently manage and adapt to display modules of varying sizes, as they lack a flexible voltage driving system that can accommodate different light source requirements, leading to suboptimal performance and compatibility issues.
Innovation Solution
A cradle with a light source driver that includes a first and second light source driving circuit, capable of generating distinct driving voltages based on the size of the display module, allowing for adaptive operation between different display modules by selectively connecting or disconnecting the driving circuits as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single light source driving circuit is used, then the device complexity is reduced, but the adaptability to different display module sizes deteriorates
Solution Approach 1:
The light source driving circuit is divided into multiple independent driving circuits (first light source driving circuit, second light source driving circuit, etc.), each capable of driving light sources of different sizes. This segmentation allows the system to adapt to various display module sizes while maintaining manageable complexity through modular architecture.
Solution Approach 2:
The cradle is designed with multiple driving circuits that can universally accommodate different display module sizes. Each driving circuit can be selectively activated based on the connected display module size, making the cradle multi-functional and compatible with various configurations without requiring separate dedicated circuits for each size.
2Adaptability or versatility
If multiple light source driving circuits are used, then the adaptability to different display module sizes is improved, but the device complexity increases
Solution Approach 1:
The cradle employs dynamic switching mechanisms that automatically or manually select which driving circuit to activate based on the connected display module size. This dynamic adaptation allows multiple driving circuits to be present without permanently increasing operational complexity, as only the necessary circuit is active at any given time.
Solution Approach 2:
A control unit or switching mechanism acts as an intermediary between the multiple driving circuits and the display module. This intermediary manages the complexity by intelligently routing signals to the appropriate driving circuit based on detected module size, shielding the user from the underlying complexity while maintaining high adaptability.
3Device complexity
If the driving voltage is fixed, then the device complexity is reduced, but the performance optimization for different display module sizes deteriorates
Solution Approach 1:
The system changes the driving voltage parameter based on the connected display module size. Different driving circuits provide different voltage levels optimized for specific module sizes, ensuring reliable performance and optimal operation. This parameter adaptation maintains reliability without requiring overly complex voltage regulation systems.

AI summary
A cradle according to an embodiment may include a housing to be coupled to display modules having various sizes and a light source driver inside the housing. The light source driver may generate a first driving voltage and a second driving voltage to be provided to a light source of the display module coupled to the housing. When the display module has a first size, the light source driver may supply only the first driving voltage to the display module. When the display module has a second size, larger than the first size, the light source driver outputs both the first and second driving voltages to the display module.
