Display Molding Structure for Impact Protection and Waterproof Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in protecting the bending areas of displays from impact and ensuring effective waterproofing without increasing the black masking area.
Innovation Solution
The electronic device incorporates a molding part that fills concave areas of the protective layer and panel layer at the display's ends, with a convex area acting as a stopper to prevent movement and reduce impact, and a waterproof member to seal the space between the molding part and the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waterproof tape is disposed between the molding part and housing to ensure waterproofing, then waterproofing is improved, but the black masking area increases
Solution Approach 1:
The patent introduces a waterproof member as an intermediary component between the molding part and housing. This waterproof member has a specific structure with a first surface contacting the housing, a second surface contacting the molding part, and a side surface forming a waterproof groove. The waterproof groove receives the end of the display, creating a multi-layer sealing system that ensures waterproofing without requiring additional black masking area, thus resolving the contradiction between waterproofing reliability and visual area.
2Strength
If the molding part is extended to cover the bending area for impact protection, then protection capability is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple functions into the molding part structure. The molding part not only provides impact protection by covering the bending area but also integrates with the waterproof member to provide sealing functionality. The convex area of the molding part acts as a stopper to prevent movement, while simultaneously protecting the display from impact. This consolidation of protection and sealing functions reduces overall device complexity compared to having separate components for each function.
Solution Approach 2:
The molding part is designed with varying thickness and coverage areas to provide localized protection where needed most. The convex area provides enhanced protection at critical points, while the overall molding part structure provides distributed protection across the bending area. This localized quality approach ensures optimal impact protection without requiring uniform thick coverage throughout, reducing material usage and complexity.
