Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Double-sided display devices face inefficiencies in heat dissipation due to unbalanced heat generation between displays, leading to inadequate cooling in one display and unnecessary energy consumption in the other, along with differing lifespans of filters and fans, making maintenance inefficient.
Innovation Solution
A display device with independent temperature measurement and airflow control systems for each side, using outlet fans and backflow prevention to optimize airflow based on temperature differences and prevent air backflow, ensuring efficient heat dissipation and energy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heat dissipation system with uniformly high output is applied to both displays, then sufficient heat dissipation is achieved in the display generating more heat, but unnecessary energy is consumed in the display generating less heat
Solution Approach 1:
The patent implements dynamic control of heat dissipation systems by independently adjusting the operation of first and second heat dissipation systems based on real-time temperature monitoring. The controller activates or deactivates each heat dissipation system according to the respective temperature of each display, enabling adaptive response to varying thermal conditions rather than uniform operation.
Solution Approach 2:
The patent applies different heat dissipation configurations to different locations (first display vs. second display) based on their individual thermal characteristics. Each display has its own dedicated heat dissipation system with independent control, allowing localized optimization of cooling performance matched to the specific heat generation of each display unit.
2Temperature
If independent heat dissipation systems are provided for both displays, then adequate cooling is achieved for each display, but the lifespan of filters and fans becomes different requiring inefficient maintenance
Solution Approach 1:
The patent divides the heat dissipation system into separate first and second heat dissipation systems, each serving one display independently. This segmentation allows each subsystem to be optimized and monitored separately, and enables independent maintenance of each system without affecting the other display, improving overall maintenance efficiency despite having multiple components.
3Use of energy by moving object
If a single heat dissipation system with uniformly low output is applied to both displays, then energy consumption is reduced, but sufficient heat dissipation cannot be achieved in the display generating more heat
Solution Approach 1:
The system dynamically adjusts the output of each heat dissipation system based on real-time temperature feedback from respective displays. When a display generates excessive heat, its corresponding heat dissipation system is activated or increased in output, while the other system can operate at lower output or remain inactive, optimizing the balance between cooling performance and energy consumption.
