Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the foldable display apparatus is folded, then the area exposed to the outside decreases, but heat dissipation becomes difficult
Solution Approach 1:
The patent introduces a plate assembly that extends in the vertical dimension beneath the display panel assembly. The lower plate extends in the direction of the display panel assembly to cover side faces, creating a three-dimensional heat dissipation structure that operates independently of the folded/unfolded state, thus resolving the heat dissipation issue when exposed area decreases.
2Ease of operation
If the foldable display apparatus is folded, then one end and the other end of the display panel come into contact, but heat generation increases and heat dissipation becomes difficult
Solution Approach 1:
The plate assembly acts as an intermediary heat dissipation structure between the display panel assembly and the environment. When the display apparatus is folded and ends contact, the plate assembly provides an additional heat dissipation pathway through its extended structure covering side faces, preventing heat accumulation at contact points.
3Reliability
If charges flow into the display panel through the side face, then the display panel may be damaged, but a longitudinal greenish problem occurs on the side face
Solution Approach 1:
The plate assembly serves as an intermediary charge dissipation path. By providing a conductive structure that extends to cover side faces, it intercepts charges before they can flow into the display panel through side faces, redirecting them to a safe dissipation path and preventing both panel damage and surface discoloration.
4Reliability
If the display panel is vulnerable to heat, then the display panel may be damaged, but the defect rate of the display panel increases
Solution Approach 1:
The plate assembly acts as a thermal intermediary between the display panel assembly and the environment. It provides an additional heat dissipation pathway that reduces thermal load on the heat-sensitive display panel, preventing heat-induced damage and reducing defect rates.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Improves heat dissipation and reduces charge inflow, maintaining panel reliability and preventing surface discoloration, while potentially reducing the apparatus' thickness and weight.
Implementation Method 1
a lot of heat is generated from a display panel... the heat generated from the display panel is not effectively dissipated to the outside... improve the performance of dissipating the heat generated from the display panel
Implementation Method 2
utilizing metal foam for enhanced thermal conductivity and charge dissipation... reduce the inflow of the charges to the display panel
