Slidable Housing Waterproof Structure for Flexible Display Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Designing a waterproof structure for slidable electronic devices is challenging due to the changing internal space during sliding, which complicates the integration of a reliable and effective waterproofing mechanism.
Innovation Solution
The implementation of a slidable electronic device design that includes a flexible display module, a sliding driver with a motor for providing driving force, and waterproof members between the frames and covers to enhance waterproof performance and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waterproof structure is designed for a slidable electronic device, then waterproof performance is improved, but device complexity increases due to the changing internal space during sliding
Solution Approach 1:
The housing is divided into multiple separable components including a first housing, a second housing, a first cover, and a second cover. Each component can be independently assembled and disassembled, allowing the waterproof structure to adapt to different sliding positions while maintaining sealing integrity. The segmentation enables the waterproof members to be positioned at critical interfaces without complicating the overall sliding mechanism.
Solution Approach 2:
Waterproof members are introduced as intermediary elements positioned between the housing components and cover components. These waterproof members act as mediators that maintain the seal at the interfaces between moving and stationary parts, solving the waterproofing challenge without requiring complex integration into the sliding driver or motor assembly.
2Reliability
If waterproof members are added between frames and covers, then waterproof performance is improved, but manufacturing complexity increases
Solution Approach 1:
The waterproof structure is segmented into multiple discrete waterproof members that can be manufactured separately and assembled into the housing components. This segmentation allows each waterproof member to be optimized for its specific location and function, simplifying the manufacturing process while maintaining effective waterproofing at all critical interfaces.
Solution Approach 2:
The waterproof members are pre-installed into the housing components during the manufacturing process, creating pre-assembled waterproof modules. This preliminary action ensures that the waterproofing function is built-in during manufacturing rather than requiring complex field assembly, thereby improving ease of manufacture while maintaining high waterproof performance.
