Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to create a lightweight large display apparatus composed of multiple modules while achieving high peak brightness, which is typically hindered by the need for a large power supply capacity, leading to increased manufacturing costs and heat generation.
Innovation Solution
The solution involves a display apparatus that implements power sharing among multiple display modules, allowing each module to receive power from multiple driving modules, thereby reducing the power capacity required for each driving module and enhancing peak brightness efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the power capacity of the power supply is increased to achieve high peak brightness, then the peak brightness is improved, but the weight of the display apparatus increases
Solution Approach 1:
The power supply system is segmented into multiple driving modules, each with a smaller individual power capacity. These modules work in parallel to collectively provide the required peak brightness, avoiding the need for a single large heavy power supply.
Solution Approach 2:
Multiple driving modules are merged to function together as a unified power delivery system. The combined output of multiple smaller modules achieves the same peak brightness as a single large module would provide, but with reduced individual weight and heat generation.
2Illumination intensity
If the power capacity of the power supply is increased to achieve high peak brightness, then the peak brightness is improved, but the manufacturing cost increases
Solution Approach 1:
The power supply is divided into multiple standardised driving modules with smaller power capacities. This segmentation allows for more economical manufacturing compared to producing a single large-capacity power supply, as smaller modules can be mass-produced more efficiently.
Solution Approach 2:
Instead of using a single power supply with high power capacity, the system changes the parameter of power distribution by using multiple modules with lower individual capacity. This parameter change enables cost-effective manufacturing while maintaining the required overall power output.
3Illumination intensity
If the power capacity of the power supply is increased to achieve high peak brightness, then the peak brightness is improved, but heat generation increases
Solution Approach 1:
The heat generation problem is addressed by segmenting the power supply into multiple driving modules. Each module generates less heat individually, and the heat is distributed across multiple locations rather than concentrated in a single large power supply, improving thermal management.
Solution Approach 2:
Multiple driving modules are combined to share the heat generation burden. The distributed architecture allows heat to be dissipated across multiple smaller units rather than from a single large unit, reducing the heat generation problem while maintaining peak brightness capability.
4Illumination intensity
If the power capacity of the power supply is increased to achieve high peak brightness, then the peak brightness is improved, but the complexity of making the display light-weight increases
Solution Approach 1:
The power supply system is segmented into multiple driving modules that can be independently managed. This segmentation simplifies the overall system design by breaking down the complex task of providing high power into multiple simpler, standardized units, making the display easier to make light-weight.
