Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices face challenges in managing static electricity discharge without increasing device size or reducing the display area, particularly when using protection members that minimize interference during folding operations.
Innovation Solution
The electronic device incorporates a housing with a protection member featuring non-conductive and conductive portions, and a side surface member with insulating and conductive materials to create an effective electrostatic discharge path, ensuring static electricity is properly managed without enlarging the device or diminishing the display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protection member is added to manage static electricity discharge, then the display is protected from damage, but the device size increases and display area is reduced
Solution Approach 1:
The protection member is designed with differentiated local properties: conductive portions (metal areas) for electrostatic discharge and non-conductive portions (resin areas) for insulation and support. This localized functional differentiation allows effective static electricity management while minimizing the overall area occupied by the protection member, thus protecting the display without significantly reducing the display area.
Solution Approach 2:
The protection member is segmented into multiple functional portions: first and second metal areas for conductive discharge paths, and resin areas for insulating and structural support. This segmentation enables each portion to perform its specific function efficiently while optimizing the overall layout to minimize space consumption and maximize display area.
2Strength
If a support member with metal and resin areas is used, then structural support is provided, but the device complexity increases
Solution Approach 1:
The support member merges multiple functions into a single integrated component: it provides structural support through the housing, conducts static electricity through metal areas, and insulates through resin areas. By combining these functions in one component rather than using separate parts, the design reduces overall device complexity while maintaining necessary structural support and electrostatic management capabilities.
Solution Approach 2:
The support member uses composite construction with both conductive (metal) and non-conductive (resin) materials integrated within the same component. This composite approach allows the single support member to simultaneously provide mechanical strength, electrostatic discharge paths, and electrical insulation, reducing the number of separate components needed and simplifying the overall device structure.
