Flexible Display Sweeper for Sliding Foreign Substance Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In foldable or rollable electronic devices, foreign substances can damage mechanical structures and electronic components like displays due to friction or interference, particularly when the flexible display is folded or rolled.
Innovation Solution
An electronic device with a flexible display that includes a sweeper member attached to its end, which slides along the inside of a second structure to block and remove foreign substances, preventing damage by sliding smoothly and discharging them outside.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display is folded or rolled in a foldable or rollable electronic device, then portability and screen size are improved, but foreign substances can enter through gaps between mechanical structures and cause damage to the display or mechanical components
Solution Approach 1:
The sweeper member is positioned in advance at the gap between the flexible display and the second structure to prevent foreign substances from entering before they can cause damage. The sweeper is pre-configured to block the entry path during folding/rolling operations.
Solution Approach 2:
The sweeper member acts as an intermediary element between the flexible display and the external environment, blocking foreign substances from entering the gap while allowing the folding/rolling motion to proceed. It mediates between the need for mechanical movement and the need to prevent contamination.
2Object-affected harmful factors
If a sweeper member is added to block foreign substances, then protection of the display is improved, but device complexity increases
Solution Approach 1:
The sweeper member is merged with the existing mechanical structure of the foldable/rollable device, specifically positioned at the gap between the flexible display and the second structure. This integration adds protection functionality without requiring a completely separate system.
Solution Approach 2:
The sweeper member is designed to automatically perform its protective function during the normal folding and rolling operations of the device. The motion of folding/rolling itself drives the sweeper to block and discharge foreign substances without requiring additional active control mechanisms.
3Productivity
If the sweeper member slides along the inside of the second structure, then foreign substances are discharged smoothly, but friction may increase
Solution Approach 1:
The sweeper member extracts or removes foreign substances from the gap between the flexible display and the second structure by sliding along the inside of the second structure. This extraction action discharges contaminants externally, preventing them from causing damage.
