Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display device uses organic light emission phenomenon, then the display can be made flexible and portable, but the device lacks convenience in configuration and operation
Solution Approach 1:
The display device employs dynamic components including rotatable members that allow the display panel to rotate between different viewing directions, and a conveyance mechanism that enables the flexible display panel to be rolled up or extended. This dynamic configuration resolves the contradiction by making the device adaptable through rotation and retraction while maintaining operational convenience through automated or assisted movement mechanisms.
Solution Approach 2:
The flexible display panel can be rolled up and stored within the device housing when not in use, creating a nested configuration. The display panel is effectively contained within the device body, allowing the device to minimize its size while maintaining full display functionality when deployed. This nesting approach enhances both flexibility and ease of operation.
2Adaptability or versatility
If the flexible display panel is made highly flexible, then portability is improved, but the device size cannot be minimized when not in use
Solution Approach 1:
The flexible display panel is designed to be rolled up and stored within the device housing, creating a compact nested configuration when not in use. The display panel fits inside the device body like a nested doll, minimizing the overall volume while maintaining full display functionality when deployed.
Solution Approach 2:
The device incorporates a conveyance mechanism that dynamically adjusts the display panel between extended and retracted states. This dynamic retraction capability allows the device to minimize its volume when the display is not needed while maintaining portability and flexibility.
3Ease of operation
If the display device allows rotation and conveyance mechanisms, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The device combines the rotation mechanism and conveyance mechanism into an integrated system. The rotatable members and conveyance mechanism work together as a unified configuration that manages the flexible display panel, reducing overall system complexity while maintaining ease of operation. The mechanisms are coordinated to provide smooth transitions between different display states.
