Curved Display Shield Mechanism for Gap Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses with display modules that can transform between flat and curved states lack effective solutions to prevent foreign materials from entering through gaps between the module and the case when in the curved state.
Innovation Solution
The display apparatus incorporates a base frame, shield members, and cover units that rotate and spread to cover the gaps between the display module and the case when in the curved state, utilizing guide pins and hinge grooves for support and movement, ensuring that foreign materials are excluded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display module is transformed to a curved state, then the user can feel a three-dimensional effect, but foreign materials can enter through spaces between the display module and the case
Solution Approach 1:
The shield member is designed to be movable rather than fixed, allowing it to dynamically adjust its position based on the display module's state. When the display module curves, the shield member moves to cover the lateral edges and block foreign material entry paths, resolving the contradiction between maintaining display functionality and preventing contamination.
Solution Approach 2:
The shield member acts as an intermediary element between the display module and the external environment. It specifically targets and blocks the lateral edge regions where foreign materials would otherwise enter, providing localized protection without interfering with the overall curved display functionality.
2Object-affected harmful factors
If shield members are added to cover the lateral edges, then foreign material entry is prevented, but device complexity increases
Solution Approach 1:
The shield member serves multiple functions simultaneously: it blocks foreign material entry at the lateral edges, maintains the aesthetic appearance of the curved display, and structurally supports the transformation mechanism. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.
Solution Approach 2:
The shield member is designed as a thin, flexible component that can adapt to the curved state of the display module. This design approach minimizes the added bulk and complexity while effectively performing the protective function, as the thin film structure can conform to the dynamic shape changes without requiring complex mechanical support.
