Display Housing Layout to Isolate Grip Areas From Heat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices pose a risk of the user holding high-temperature portions, such as the control board and battery, which can lead to discomfort or injury.
Innovation Solution
The display device is designed with a housing configuration that separates high-temperature components from user-gripped areas, using thermal conductive sheets and heat transfer members to manage heat dissipation and prevent temperature buildup in touchable regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If heat transfer unit transfers heat from heat generating component to display panel, then heat dissipation efficiency is improved, but user safety deteriorates due to risk of holding high-temperature portions
Solution Approach 1:
The housing is divided into distinct functional zones: a first housing portion containing heat-generating components (control board, battery) and a second housing portion designed for user gripping. This spatial segmentation isolates thermal hazards from user contact areas while maintaining effective heat dissipation pathways through dedicated heat transfer units.
Solution Approach 2:
Different regions of the housing are assigned different thermal properties and functions. The first housing portion near heat-generating components incorporates heat transfer units with high thermal conductivity for efficient heat evacuation, while the second housing portion has thermal insulation characteristics to maintain safe surface temperatures for user contact.
2Loss of energy
If heat transfer unit transfers heat to display panel, then heat dissipation is improved, but display panel temperature increases
Solution Approach 1:
The heat dissipation function is extracted from the display panel and assigned to a dedicated heat transfer unit. This separate thermal management component absorbs heat from the display panel and conducts it to the housing, allowing the display panel to maintain lower operating temperatures while heat is efficiently removed through the specialized heat transfer pathway.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents user contact with high-temperature components and maintains a comfortable operating temperature for the display device, ensuring safety and usability.
Implementation Method 1
a heat transfer unit transfers heat generated from a heat generating component inside a housing of an electronic device to a display panel and the heat is radiated from the display panel
Implementation Method 2
the heat is radiated from the display panel for the purpose of efficiently releasing heat

AI summary
A display device (100) includes a housing (110), a screen (121A), and a control board (131). The housing (110) includes grip portions (R1, R2) to be gripped at a right end portion and a left end portion of the housing (110) in a horizontal direction. The screen (121A) is on a front face of the housing (110). The control board (131) controls the display device (100) and is disposed at a position at which the control board (131) does not overlap with the grip portions (R1, R2) in a direction orthogonal to the screen (121A).
