Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a trade-off between the display size and compactness of electronic devices, making it difficult to provide sufficient multimedia services while maintaining portability.
Innovation Solution
An electronic device with a housing that includes a first and second housing allowing sliding movement, an elastic member to guide this movement, and sensors to determine the sliding distance, adjusting the display size based on the sensed pressure.

1Area of moving object
If the display size is increased to provide sufficient multimedia services, then the display capability is improved, but the device compactness deteriorates
Solution Approach 1:
The display is designed to be dynamically adjustable in size through sliding movement between a retracted state (for compactness) and an extended state (for multimedia services). The elastic member enables this dynamic transformation, allowing the display to change its effective area based on operational needs rather than being fixed.
Solution Approach 2:
The housing is divided into a first housing and a second housing that can slide relative to each other. The display is segmented such that it can be partially or fully retracted into the housing, allowing the display area to be divided between a visible portion and a stored portion, thus achieving both compactness and adequate display capability.
2Adaptability or versatility
If the display is made slidable to adjust size, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The elastic member is configured to automatically push the display to its extended position when the housing is assembled, eliminating the need for additional motors or actuators. The system uses the elastic force stored during assembly to provide the sliding action, reducing mechanical complexity while maintaining adaptability.
Solution Approach 2:
The elastic member acts as an intermediary element between the housing components and the display, mediating the sliding movement through its elastic deformation. This simple mechanical intermediary replaces complex control systems, achieving display size adjustment through material properties rather than active control mechanisms.
