Solution Overview
Problem
Current display devices face challenges in storage and portability, durability, rigidity, and heat dissipation, particularly for portable applications.
Innovation Solution
A display device design featuring a modular structure with a display module, a bottom case, and a top case, including a panel frame, side cover, and bumper, which facilitates storage, enhances rigidity through specific frame configurations, and incorporates heat dissipation mechanisms using shield members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display device is designed for portability, then storage and portability are improved, but durability and rigidity deteriorate
Solution Approach 1:
The display device is divided into multiple segments including a display module, bottom case, and top case. The display module itself is segmented into panel frame, side cover, and bumper components. This segmentation allows each part to be optimized independently - the frame and bumper provide structural strength while the modular design maintains portability.
Solution Approach 2:
The device employs composite structural design combining different materials and components - the panel frame, side cover, and bumper work together as a composite structure. The bumper acts as a protective composite element that enhances durability without compromising the overall portable design.
2Reliability
If protective structures are added to improve durability, then shock absorption is improved, but device complexity increases
Solution Approach 1:
The bumper is integrated with the side cover and panel frame to form a unified protective structure. This merging approach provides shock absorption and durability enhancement without adding separate complex protective mechanisms, thereby maintaining structural simplicity.
Solution Approach 2:
The bumper is positioned at corners and edges of the display module to provide beforehand cushioning against potential impacts. This preventive protective design absorbs shocks before they reach critical components, improving durability without requiring complex active protection systems.
