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 measurements from sensors. When one display generates excessive heat, its corresponding heat dissipation system is activated or intensified, while the other side operates at reduced capacity or remains inactive, optimizing energy consumption based on actual thermal conditions.
Solution Approach 2:
The patent applies different heat dissipation intensities to different sides of the display device. Each display side has its own dedicated heat dissipation system that can be independently controlled, allowing localized heat management tailored to the specific thermal load of each side rather than applying uniform cooling across the entire device.
2Temperature
If independent heat dissipation systems are provided for both displays, then sufficient heat dissipation is achieved for each display, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent divides the heat dissipation system into separate first and second heat dissipation systems, each dedicated to a specific display side. This segmentation allows independent control and optimization of heat dissipation for each side while maintaining modular architecture that simplifies implementation and maintenance compared to a unified complex system.
3Temperature
If a direct cooling structure is used to shut off external air, then heat exchange efficiency is improved, but dust accumulation on filters increases and maintenance frequency increases
Solution Approach 1:
The patent incorporates temperature sensors that continuously monitor thermal conditions and provide feedback to the control system. Based on this feedback, the system intelligently manages the direct cooling structure operation, activating it only when necessary to maintain optimal temperatures, thereby reducing unnecessary filter exposure to dust while ensuring adequate heat dissipation when thermal loads require it.
