Solution Overview
Problem
There is a need for display apparatuses that offer portability and storage convenience, particularly for larger and high-resolution displays, which can be easily expanded and reduced in size by folding or rolling.
Innovation Solution
A rollable display apparatus featuring a flexible display panel attached to a support portion with a magnet, spirally wound around a main body portion made of metallic material, allowing for expansion and storage by using a joint mechanism and magnetic fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a flexible display panel is made larger and high-resolution, then display quality is improved, but portability and storage convenience deteriorate
Solution Approach 1:
The display apparatus transitions from a static rigid structure to a dynamic flexible structure. The flexible display panel and support portion can be rolled up into a compact state for portability, then unrolled to provide a large high-resolution display surface when needed, allowing the system to adapt its physical state to different usage scenarios
Solution Approach 2:
The invention replaces traditional rigid display structures with flexible components including a flexible display panel and a flexible support portion. This flexibility enables the large high-resolution display to be rolled into a compact form factor for easy transport, while maintaining display quality when deployed
2Ease of operation
If a flexible display panel is rolled up for storage, then portability is improved, but structural stability deteriorates
Solution Approach 1:
The support portion transitions from a rigid static structure to a flexible dynamic structure that can adapt its form. When rolled, the flexible support portion maintains structural integrity through its material properties and design, providing stability in both rolled and unrolled states without requiring complex mechanical fastening systems
Solution Approach 2:
The invention replaces traditional mechanical fastening systems (screws, clips, adhesives) with magnetic attachment. Magnets embedded in the support portion securely hold the flexible display panel in both rolled and unrolled states, providing stable attachment without mechanical complexity while maintaining ease of deployment
3Ease of manufacture
If magnets are used to attach the flexible display panel, then ease of assembly is improved, but manufacturing complexity worsens
Solution Approach 1:
The magnets are integrated directly into the support portion structure, combining the attachment function with the structural component. This merging eliminates the need for separate attachment mechanisms and simplifies the overall manufacturing process, as the magnets become an inherent part of the support portion rather than an additional component
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient portability and storage while maintaining a high-resolution display with accurate touch input and distortion-free image viewing, as the flexible panel can be easily rolled and unrolled with user-preferred direction and secure magnetic attachment.
Implementation Method 1
The extension portion includes a magnet that attaches the flexible display panel to the main body portion
