Solution Overview
Problem
Display devices face challenges in supporting display panels, managing heat dissipation, and providing high-quality sound, particularly in terms of structural stability, cable management, and sound path optimization.
Innovation Solution
The design includes a stand with a top plate and side plates that support the display panel, a heat dissipation mechanism with a back cover and rigid bar, and a sound reflector with an inclined part to direct sound from the speaker, ensuring stability, efficient heat dissipation, and high-quality sound output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a stand structure is designed to support the display panel, then structural stability is improved, but device complexity increases
Solution Approach 1:
The stand is divided into multiple functional components: top plate for support, side plates for structural integrity, bottom plate for stability, and guide grooves for cable management. This segmentation allows each part to perform its specific function efficiently while keeping the overall design manageable and not excessively complex.
2Ease of operation
If guide grooves are added to the stand for cable management, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The cable management function is merged into the existing stand structure by incorporating guide grooves directly into the side plates and bottom plate. This integration allows cable routing to be accomplished using the same structural components that provide support, rather than adding separate cable management devices, thereby minimizing additional complexity.
3Reliability
If heat dissipation mechanisms are implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
The stand structure itself serves the heat dissipation function through its design features. The bottom plate and side plates create air circulation pathways that allow natural convection cooling of electronic components. The structure provides its own thermal management capability without requiring separate active cooling systems, thereby maintaining simplicity while improving reliability.
4Temperature
If a rigid bar structure is used for heat dissipation, then heat dissipation efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
The rigid bar is designed with specific local features: elongated holes for thermal contact with components, and positioning protrusions that fit into guide grooves. These local quality enhancements focus manufacturing precision only where critical for thermal performance, rather than requiring high precision throughout the entire component, making the manufacturing process more feasible.

AI summary
A display device including a display panel; a frame coupled to a rear of the display panel; at least one first guide plate fixed to a rear of the frame and having a guide groove; and a stand positioned below the display panel. Further, the stand include a top plate including at least one protruding support guide inserted into the guide groove of the at least one first guide plate to couple the display panel to the stand; a bottom plate spaced apart from the top plate; first and second side plates connecting the top plate and the bottom plate; and a bottom receiving part coupled to a lower part of the bottom plate and including an electronic component accommodation space.
