Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Thin display apparatuses experience overheating due to heat transfer between components, leading to degraded performance and potential failure, as heat generated by heating components is easily transferred to other components, affecting image quality and causing thermal deformation.
Innovation Solution
A display apparatus structure featuring a support member that vertically separates the control assembly and holder, using a rotation supporter and coupling pin to maintain contact between the control assembly, shield cover, heat transfer member, and back cover, ensuring effective heat dissipation despite thermal deformation.

1Length of moving object
If the display apparatus is made thin to improve portability and user convenience, then the overall thickness is reduced, but heat generated from heating components is easily transferred to other components due to close distance, causing overheating and performance degradation
Solution Approach 1:
A heat transfer member is introduced as an intermediary component between the heating component and other nearby components. This heat transfer member has high thermal conductivity and is specifically designed to conduct heat away from the heating component to a heat sink, preventing harmful heat transfer to other components while maintaining the thin overall structure.
Solution Approach 2:
The heat dissipation function is extracted and separated from the main display structure by introducing a dedicated heat transfer member and heat sink system. This allows the thin display apparatus to have effective heat management without adding significant thickness, as the heat transfer member is positioned to conduct heat laterally rather than requiring additional vertical space.
2Temperature
If heat transfer members made of high thermal conductivity material are used to improve heat dissipation, then heat is easily transferred to external atmosphere, but thermal deformation causes the heat transfer member to be spaced apart from the heating component, degrading heat dissipation performance
Solution Approach 1:
The support structure for the heat transfer member is designed to be dynamically adjustable rather than rigidly fixed. This allows the support structure to compensate for thermal expansion and contraction of the heating component, maintaining continuous contact between the heat transfer member and the heating component despite temperature-induced dimensional changes.
Solution Approach 2:
The material properties of the heat transfer member and its support structure are selected to have compatible thermal expansion coefficients. This parameter matching ensures that when temperature changes occur, both components expand or contract at similar rates, preventing separation or excessive contact pressure that would degrade heat dissipation performance.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The structure effectively suppresses heat transfer by conduction, maintaining contact between components and preventing overheating, thereby enhancing heat dissipation performance and preventing thermal deformation-induced failures.
Implementation Method 1
heat transfer members made of a material having high thermal conductivity are in contact with each other so that heat generated from the heating components is easily transferred to the external atmosphere
Implementation Method 2
