Retractable Display Panel With Roller Support Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile electronic devices face challenges in minimizing the volume occupied by display units while maintaining portability and operability, as the display units often require a compact structure that can bend and expand for user interaction.
Innovation Solution
A display device design featuring a first and second housing with a retractable display panel and support member, utilizing rollers and elastic units to wind and unwind the panel and support member, allowing for compact storage and easy deployment, with an insulating member to prevent damage and enhance user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the display unit is made compact to minimize volume, then portability is improved, but the display area and user interaction capability deteriorate
Solution Approach 1:
The display device employs a dynamic structure where the display panel can be pulled out from the housing to increase display area when needed, and retracted to minimize volume when not in use. The panel moves between a stored position within the housing and an extended position for user interaction, allowing the device to adapt its configuration based on usage requirements.
Solution Approach 2:
The display panel is nested within the housing structure, allowing it to be stored compactly inside the device body. The panel can be extracted from the housing to provide full display functionality, effectively nesting the display area within the limited device volume while maintaining both compact storage and expanded usage states.
2Volume of moving object
If the display panel is made flexible and retractable, then portability is improved, but the reliability and protection of the display panel deteriorates
Solution Approach 1:
The device includes a support member that is pulled out from the housing simultaneously with or before the display panel during the retraction process. This support member provides structural reinforcement and protection to the flexible display panel, preventing damage that could occur during bending and retraction operations.
Solution Approach 2:
The display panel utilizes a flexible substrate structure that allows it to be bent and retracted into the housing. The flexible nature of the panel enables it to conform to the compact storage configuration while maintaining structural integrity through specialized flexible materials and construction.
3Ease of operation
If the display panel is pulled out for use, then user interaction capability is improved, but the device complexity increases
Solution Approach 1:
The device is divided into separable components including the housing, the retractable display panel, and the support member. Each component can move independently through guided paths, allowing the complex functionality of a retractable flexible display to be achieved through simpler, modular mechanical elements rather than a single complex mechanism.
