Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If the bezel region is reduced to improve aesthetics and display quality, then the visual appearance is improved, but the integration of functional elements (speakers, sensors) becomes more difficult

Engineering Contradiction:

Improveaesthetic appearanceVSAvoidintegration complexity

Core Design Contradiction:

ShapeVSDevice complexity

Solution Approach 1:

The window is divided into a first region with a flat surface and a second region with a curved surface containing holes. This segmentation allows functional elements to be integrated in the second region without compromising the aesthetic flat appearance of the first region that dominates the visual field.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the window have different surface characteristics: the first region has a flat surface for aesthetics, while the second region has a curved surface with holes for functional element integration. This local differentiation resolves the contradiction between overall aesthetic appearance and local functional requirements.

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If holes are added to the window to accommodate functional elements, then functionality is improved, but the visual integrity and aesthetics of the display module may be compromised

Engineering Contradiction:

Improvefunctional integrationVSAvoidvisual integrity

Core Design Contradiction:

Adaptability or versatilityVSShape

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The window features an asymmetric design where the majority (first region) maintains a flat, visually intact surface, while a smaller portion (second region) contains the curved surface with holes. This asymmetric placement minimizes the visual impact of holes while maximizing functional integration.

Inventive Principle:

Principle #4Asymmetry

3Adaptability or versatility

If a curved surface is created in the window to accommodate functional elements, then functional integration is improved, but the manufacturing complexity increases

Engineering Contradiction:

Improvefunctional element integrationVSAvoidmanufacturing complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The curved surface and holes are formed in the glass substrate before the final assembly. The beam irradiation modifies the glass structure in advance, making subsequent etching easier and more precise, thereby reducing overall manufacturing complexity despite the curved geometry.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Traditional mechanical drilling or cutting methods are replaced with beam irradiation followed by etching. This substitution enables precise formation of curved surfaces and holes with better control over depth and shape, reducing manufacturing complexity and improving precision.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
