Sliding Flexible Display PCB Layout for Reliable Housing Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible displays in electronic devices face challenges in electrically connecting components outside the housing to the printed circuit board due to the presence of guide structures, making it difficult to establish a reliable connection by wire.
Innovation Solution
The electronic device incorporates a first and second housing with a flexible display that allows a portion of the second display area to be exposed through slide movement, featuring a first and second circuit board connected via a hole in the second housing, and an antenna module connected to the second circuit board, which is connected to the first circuit board through a hole in the cover member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a touchscreen display device is made smaller to fit in a pocket, then portability is improved, but the screen size and input area are reduced making the device difficult to operate
Solution Approach 1:
The patent implements a dynamic screen configuration where the display can transition between a first configuration (first orientation/size) and a second configuration (second orientation/size). This allows the device to adapt its operational characteristics based on usage context, providing larger interaction areas when needed while maintaining compact form factor for portability.
2Volume of moving object
If the device is kept compact for portability, then it can fit in a pocket, but the screen cannot provide a large enough area for comfortable interaction
Solution Approach 1:
The patent utilizes orientation change as an additional dimension to increase screen area. By rotating or reorienting the display between different configurations, the device effectively increases its usable screen area without increasing its physical volume, allowing comfortable interaction while maintaining pocketability.
3Ease of operation
If the screen is made larger to improve visibility and input area, then operability is improved, but the device becomes too large to carry conveniently
Solution Approach 1:
The dynamic screen configuration allows the device to provide a larger input area when needed for operation, then return to a compact configuration for carrying. This temporal separation of operational and portable states resolves the contradiction between needing large input area and maintaining small device size.
