Display Panel Housing-Cover Coupling for Waterproof Compact Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face issues with increased size, manufacturing complexity, and vulnerability to moisture and foreign substances due to protective cover members and housings, which can lead to damage and limited installation space.
Innovation Solution
A display device design featuring a cover member with a first bent portion and groove, and a housing with a protrusion that couples to the groove, reducing size and eliminating the need for additional parts, while incorporating a groove in the housing to store and evaporate moisture, and using a sealing member to prevent foreign substances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cover member and housing are added to protect the display panel, then the display device becomes more resistant to external damage and moisture, but the size of the display device increases and installation space is limited
Solution Approach 1:
The cover member and housing are merged into a single integrated component that provides both protective functions. The cover member itself is designed with a housing-like structure that includes side surfaces extending downward, eliminating the need for a separate housing component while maintaining protection against external damage and moisture.
Solution Approach 2:
The groove structure is nested within the cover member's side surface, creating a coupled relationship between the cover member and housing portions. The protrusion of the housing fits into the groove of the cover member, allowing the housing to be nested within the overall structure without significantly increasing the external dimensions of the display device.
2Reliability
If additional parts are added to couple or fix protective components, then the protective structure becomes more secure, but manufacturing costs and processes increase
Solution Approach 1:
The coupling mechanism is integrated into the cover member and housing structures themselves through the groove-protrusion interface. This eliminates the need for separate fasteners, adhesives, or other coupling parts, reducing both the number of components and the complexity of manufacturing processes while maintaining secure attachment.
Solution Approach 2:
The groove and protrusion structures are designed to self-align and self-couple during assembly. The geometric features automatically guide the housing into the correct position relative to the cover member and provide inherent mechanical interlocking, eliminating the need for additional fixing operations or parts.
3Adaptability or versatility
If the display device is exposed to various environments, then the display device can be used in more applications, but moisture and foreign substances can flow into the display device through coupling areas
Solution Approach 1:
The groove-protrusion coupling structure, which could potentially create gaps for moisture entry, is designed so that the protrusion fully engages with the groove to create a tight fit. The coupled interface between the cover member and housing eliminates the coupling gap, converting a potential vulnerability into a sealed connection that prevents moisture and foreign substance infiltration.
Solution Approach 2:
The cover member is designed with extended side surfaces that act as a sealing barrier. The integrated structure creates continuous protective surfaces that prevent moisture and foreign substances from reaching the display panel through the coupling area, providing environmental sealing without requiring additional gaskets or seals.
