Solution Overview
Problem
The challenge of integrating a deformable display in a portable electronic device while maintaining effective wireless communication capabilities, particularly in a housing that protects the display and allows for flexible expansion and contraction.
Innovation Solution
The electronic device incorporates a housing with movable parts that house a wireless communication circuit and a deformable display, featuring conductive and non-conductive portions to facilitate communication through a second conductive portion, allowing the display to roll or slide into the housing while maintaining connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the housing includes multiple conductive portions separated from each other to enable wireless communication, then wireless communication capability is improved, but the housing structure becomes more complex
Solution Approach 1:
The housing is divided into multiple conductive portions (first conductive portion, second conductive portion, third conductive portion) that are separated from each other by non-conductive portions. Each conductive portion can function independently for wireless communication, allowing the system to achieve reliable communication while managing structural complexity through functional segmentation.
Solution Approach 2:
Different portions of the housing have different electrical properties - some areas are conductive for antenna functions while other areas are non-conductive for isolation. This local differentiation of material properties enables the housing to simultaneously provide communication capabilities and structural management without uniform complexity throughout.
2Adaptability or versatility
If the display is deformable and can be rolled into the housing, then device portability is improved, but maintaining wireless communication during deformation becomes difficult
Solution Approach 1:
The housing is segmented into multiple conductive portions separated by non-conductive portions. This segmentation ensures that when the display is deformed or rolled, the conductive portions remain electrically isolated from each other, maintaining stable antenna performance and wireless communication reliability despite the dynamic configuration changes.
Solution Approach 2:
Non-conductive portions act as intermediaries between conductive portions, providing electrical isolation that allows the housing structure to deform with the display while maintaining stable electrical connections for wireless communication. The non-conductive material mediates between the mechanical deformation and electrical stability requirements.
