Solution Overview
Problem
Optimizing the Z form factor of portable information handling systems, particularly those with infinity edge designs, to enhance aesthetics, strength, and performance while competing with systems having smaller form factors.
Innovation Solution
A display assembly comprising a display cover portion with an infinity display and a rear cover portion featuring a timing controller with multi-level printed circuit boards, where the second printed circuit board is taller and located within the dome center height area, providing a tiered design that optimizes the Z form factor and visual perception of a smaller size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a portable information handling system uses an infinity edge display design, then the aesthetic appearance and visual perception are improved, but the Z form factor (thickness) increases making the device appear thicker than competitors
Solution Approach 1:
The patent introduces a multi-level printed circuit board structure with varying heights (first level, second level, third level) to create a tiered arrangement. This dimensional variation in the Z-direction allows components to be stacked at different elevations, optimizing space utilization and reducing the overall perceived thickness while maintaining the infinity edge display aesthetic.
Solution Approach 2:
The printed circuit board is segmented into multiple levels with different heights, creating distinct tiers for mounting components. This segmentation allows the timing controller and other components to be distributed across different elevation planes, enabling better space management and reducing the maximum Z-form factor of the device.
2Length of moving object
If components are arranged to reduce the Z form factor, then the perceived thickness is reduced, but the structural complexity and manufacturing difficulty increase
Solution Approach 1:
The patent combines multiple printed circuit board levels into a single integrated structure where the first, second, and third levels are formed as part of one continuous board. This merging approach reduces the number of separate components and assembly steps compared to using multiple discrete boards, thereby simplifying manufacturing while achieving the desired multi-level component arrangement.
3Length of moving object
If the timing controller and other components are positioned to optimize the dome center height area, then the visual perception of thickness is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent creates different height zones (first dome center height area, second dome center height area, third dome center height area) within the printed circuit board structure. Each zone is optimized for specific component placements, with the timing controller positioned in the second dome center height area. This local differentiation allows components to be arranged according to their specific requirements while maintaining overall aesthetic consistency.
