Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in reducing bezel width, improving durability, and enhancing manufacturing efficiency.
Innovation Solution
A display device design incorporating a housing, a display panel, a cover layer with a protruding area, an inner mold spaced from the display panel, and a sealing member contacting the display panel, cover layer, and inner mold, along with a manufacturing method that includes coupling and filling the sealing member between these components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the inner mold is disposed close to the display panel to reduce bezel width, then the bezel width is reduced, but the structural stability and durability are compromised
Solution Approach 1:
The patent introduces a sealing member as an intermediary component positioned between the inner mold and the display panel. This sealing member fills the spacing S and provides structural support while maintaining the reduced bezel width design, thus resolving the contradiction between compact dimensions and structural stability.
Solution Approach 2:
The inner mold is nested within the housing structure with the sealing member interposed, creating a layered configuration. This nested arrangement allows the components to be closely spaced while maintaining structural integrity through the hierarchical organization of elements.
2Reliability
If the inner mold is spaced far from the display panel to improve durability, then structural stability is improved, but the bezel width increases
Solution Approach 1:
The sealing member acts as a mediator that provides structural support and durability without requiring large spacing between the inner mold and display panel. This allows the system to achieve enhanced durability while maintaining a compact bezel width.
3Manufacturing precision
If a complex assembly process is used to achieve precise positioning, then manufacturing precision is improved, but manufacturing efficiency decreases
Solution Approach 1:
The housing is designed with pre-formed recesses and the inner mold is designed with pre-formed protrusions that complement each other. This preliminary action of creating matching geometric features enables precise positioning to occur automatically during assembly, eliminating the need for complex positioning procedures and maintaining high manufacturing efficiency.
Solution Approach 2:
The complementary recess-protrusion geometry creates a self-aligning assembly system where components naturally find their correct positions through geometric constraints, making the assembly process as straightforward as fitting puzzle pieces together.
