Slidable Rollable Display Layout for Battery Space and Lower Stress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Slidable electronic devices face challenges in securing sufficient internal space for components due to overlapping structures and reduced space during sliding operations.
Innovation Solution
A slidable electronic device design featuring a first and second housing that slide in opposite directions, with a rollable display and a battery positioned to avoid overlap, allowing for a dedicated accommodation area and sufficient space for components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If components are added for sliding operation, then the slidable function is achieved, but the internal space for placing electronic components is reduced
Solution Approach 1:
The patent positions the battery in the thickness direction (third direction) of the device rather than only in the planar directions, utilizing the Z-axis space above and below the rollable display. This dimensional change allows the battery to coexist with the sliding mechanism without compromising either the slidable function or the battery capacity.
2Volume of stationary object
If electronic components overlap in the slide-in state, then space utilization is maximized, but the available space for battery placement is reduced
Solution Approach 1:
The patent divides the device into two housings (first housing and second housing) that can slide relative to each other, creating distinct spatial zones. The battery is placed in the first housing while the rollable display and its accommodation area are in the second housing, preventing overlap and ensuring both functions can coexist with adequate space.
3Strength
If the rear cover overlaps the accommodation area, then structural support is provided, but the stress on the rollable display increases
Solution Approach 1:
The patent extracts the rear cover from the second housing and relocates it to the first housing, positioning it above the battery rather than overlapping the accommodation area. This separation eliminates the source of stress concentration on the rollable display while maintaining structural support through alternative design arrangements.
