Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in storage and portability, durability, rigidity, heat dissipation, and shock absorption, particularly for portable applications.
Innovation Solution
A display device design featuring a display module, a bottom case for mounting, a top case for closure, and a hinge assembly, along with structural elements like a frame made of high-strength, ultra-light materials and heat dissipation sheets, and a shock-absorbing bumper to enhance rigidity and protect against impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a display device is designed for portability, then ease of storage and transport is improved, but durability and rigidity deteriorate
Solution Approach 1:
The display device is divided into separate modular components including a display module, bottom case, top case, and hinge assembly. This segmentation allows the device to be folded into a compact form for portability while maintaining structural integrity through standardized connection interfaces between modules.
Solution Approach 2:
The patent employs composite material construction for the case components, combining materials with different properties to achieve both lightweight characteristics for portability and sufficient mechanical strength for durability. The hinge assembly integrates multiple materials to provide both flexibility for folding and rigidity for structural support.
2Strength
If the display device structure is made more complex to improve durability, then strength is improved, but device complexity increases
Solution Approach 1:
The device is segmented into standardized modules (display module, bottom case, top case, hinge assembly) that can be manufactured independently and assembled through standardized interfaces. This reduces overall structural complexity while maintaining durability through modular reinforcement at critical connection points.
Solution Approach 2:
The hinge assembly incorporates shock-absorbing elements and protective structures designed in advance to withstand repeated folding and unfolding operations. This preemptive cushioning design enhances durability without requiring complex protective mechanisms during operation.
