Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional display device structure is used, then device complexity is low, but heat dissipation efficiency is poor leading to poor image quality and component breakdown
Solution Approach 1:
The patent divides the internal space into multiple independent heat dissipation spaces (first heat dissipation space between display panel and third side wall, second heat dissipation space between first airflow-blocking plate and fourth side wall, third heat dissipation space between first airflow-blocking plate and second side wall). Each space is dedicated to dissipating heat from specific components, improving overall heat dissipation efficiency while maintaining manageable structural complexity through modular organization.
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement by positioning airflow-blocking plates at different locations and orientations within the shell. The first airflow-blocking plate is positioned between the first side wall and back surface, while the second and third airflow-blocking plates are positioned at opposite sides, creating multiple heat dissipation pathways in different spatial dimensions to maximize heat dissipation efficiency.
2Reliability
If airflow channels are added to improve heat dissipation, then heat dissipation efficiency improves, but device complexity increases
Solution Approach 1:
The shell structure serves multiple functions simultaneously: it provides mechanical protection for internal components, defines the airflow channels for heat dissipation, and supports the display panel and airflow-blocking plates. The third side wall with its light-passing portion and opaque portion integrates both structural support and optical functions, reducing the need for separate dedicated components.
Solution Approach 2:
The airflow-blocking plates act as intermediary elements that guide and control air flow through the heat dissipation spaces. These plates are positioned to block unnecessary air flow paths while allowing controlled air circulation through the designated channels, efficiently directing heat away from components without requiring complex active flow control systems.
3Reliability
If fans are added to pump air through heat dissipation spaces, then heat dissipation efficiency improves, but device complexity and power consumption increase
Solution Approach 1:
The patent employs natural convection currents driven by temperature differences to facilitate air flow through the heat dissipation spaces. Hot air rises and circulates naturally through the designated channels, while cooler air is drawn in to replace it, creating a self-sustaining heat dissipation system without requiring active mechanical fans, thereby reducing device complexity and power consumption.
