Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of flat display panels into large-sized electronic home appliances and the demand for flexible, aesthetically appealing designs pose challenges in providing versatile and damage-preventive solutions for display apparatuses, particularly in terms of edge management and lighting control.
Innovation Solution
A display apparatus featuring a flexible display panel with an edge-roll implementation unit, a lighting unit, and a control unit that independently controls bimetal elements and luminance based on light sensing, allowing for edge rolling, unrolling, and lighting adjustments to create aesthetic effects and protect the device during non-use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel is made flexible and edges are made rollable, then aesthetic effects and decorative functionality are improved, but the risk of damage during transportation and non-use increases
Solution Approach 1:
The display panel edges are designed to be dynamically changeable between rolled and unrolled states. The edge-roll implementation unit enables the edges to transition between different configurations, allowing the display apparatus to adapt its shape for aesthetic effects during use while maintaining a protective flat state during transportation and non-use.
Solution Approach 2:
The physical state of the display panel edges is changed through parameter control. By applying voltage to the bimetal elements, the edge curvature and shape are modified, enabling the edges to transition between rolled and unrolled states. This parameter change allows the same structure to serve both aesthetic and protective functions.
2Adaptability or versatility
If lighting units are added to illuminate the rolled edges, then aesthetic effects are improved, but device complexity and energy consumption increase
Solution Approach 1:
The lighting unit is integrated with the edge-roll implementation unit, merging the illumination function with the edge control system. This integration allows the lighting to be activated simultaneously with the edge rolling function, providing aesthetic illumination without requiring completely separate control systems.
Solution Approach 2:
The control unit performs multiple functions by controlling both the edge-roll implementation unit and the lighting unit. A single control system manages both the mechanical edge transformation and the illumination, reducing overall device complexity while maintaining aesthetic functionality.
3Adaptability or versatility
If multiple edge-roll devices with independent control are used, then flexibility and aesthetic control are improved, but manufacturing complexity and cost increase
Solution Approach 1:
The edge-roll implementation unit is divided into multiple independent edge-roll devices, with each device controllable by separate voltage application. This segmentation allows for flexible and differentiated control of different edge sections, enabling complex aesthetic effects while maintaining relatively simple individual device structures that can be manufactured independently.
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
The solution enables the display apparatus to provide various aesthetic effects, act ornamentally, and prevent damage by selectively transforming its edges, ensuring durability during transportation and non-decorative use.
Implementation Method 1
Each of the edge-roll devices may include a bimetal element.
Implementation Method 2
The display apparatus may further include a light sensing unit for sensing light at a periphery of the display apparatus.
