Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face the challenge of direct heat transfer from electrical components to the display panel, which can compromise the integrity and performance of the panel without complex heat management solutions.
Innovation Solution
The display device incorporates an inner plate with an insulation region having a lower heat transfer coefficient than the plate body, featuring insulating through holes to create an air gap between electrical components and the panel, and a rear chassis with heat transfer portions to manage heat dispersion effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the display device uses a thin structure to reduce thickness, then the thickness of the display device is reduced, but heat generated by electrical components directly transfers to the display panel
Solution Approach 1:
The patent introduces an inner plate with insulation regions as an intermediary component between the electrical components and the display panel. This inner plate includes heat transfer portions with lower heat transfer coefficients that block direct heat paths from electrical components to the display panel, while allowing thermal management through controlled heat dissipation paths.
Solution Approach 2:
The inner plate is segmented into different regions with different thermal properties: heat transfer portions with lower heat transfer coefficients for insulation and other portions for heat dissipation. This segmentation allows the structure to simultaneously achieve thermal isolation and thermal management functions.
2Object-affected harmful factors
If insulation regions are added to block heat transfer, then heat transfer to display panel is reduced, but the structure becomes more complex
Solution Approach 1:
The patent merges the thermal management function into the existing inner plate structure by creating regions with different heat transfer coefficients within the same component. This integration avoids adding separate insulation components and maintains structural simplicity while achieving effective heat blocking.
3Object-affected harmful factors
If insulating through holes are formed in the inner plate, then heat transfer is reduced through air gap formation, but manufacturing complexity increases
Solution Approach 1:
The patent replaces complex multi-component insulation structures with a simplified inner plate that uses insulating through holes to create air gaps. This mechanical design substitution achieves effective thermal isolation through straightforward hole formation processes, reducing manufacturing complexity compared to traditional multi-layer insulation systems.
