Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a glass cover is arranged on the surface of the flexible screen to protect the screen from physical damage, then the screen protection is improved, but the flexibility of the display screen is sacrificed

Engineering Contradiction:

Improvescreen protectionVSAvoidflexibility of display screen

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The glass cover is segmented into multiple portions (first portion, second portion, third portion) with different structural characteristics. The first portion includes a target texture structure with deformation objects to reduce stress, the second portion has a different texture structure, and the third portion has yet another texture structure. This segmentation allows different regions of the glass to have different flexibility characteristics, enabling the glass to protect the screen while maintaining overall flexibility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different portions of the glass cover are given different local qualities through distinct texture structures. The first portion has a target texture structure optimized for flexibility, while other portions have different texture structures optimized for their specific functional requirements. This local differentiation allows the glass to simultaneously achieve protection and flexibility in different areas.

Inventive Principle:

Principle #3Local quality

2Reliability

If a glass cover is arranged on the surface of the flexible screen to protect the screen from physical damage, then the screen protection is improved, but the user experience is compromised

Engineering Contradiction:

Improvescreen protectionVSAvoiduser experience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The glass cover is divided into multiple portions with different texture structures, where the first portion with the target texture structure provides enhanced flexibility to improve user experience during interaction, while other portions maintain protective functions. This segmentation allows the glass to adapt to both protection and user experience requirements.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different portions of the glass cover have different local qualities optimized for specific functions. The first portion has a target texture structure that enhances flexibility for better user interaction, while other portions have different texture structures optimized for protection and durability, creating a balanced user experience.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If the glass is made thinner to improve flexibility, then the flexibility is improved, but the protection capability is reduced

Engineering Contradiction:

ImproveflexibilityVSAvoidprotection capability

Core Design Contradiction:

Adaptability or versatilityVSStrength

Solution Approach 1:

The target texture structure in the first portion of the glass includes deformation objects that create a porous or textured internal structure. This allows the glass to maintain thickness for protection while the textured structure provides flexibility by allowing controlled deformation. The porous/textured structure enables the glass to bend without breaking while maintaining its protective thickness.

Inventive Principle:

Principle #31Porous materials

Solution Approach 2:

The glass cover employs a composite structure with different texture patterns in different portions. The first portion has a target texture structure designed for flexibility, while other portions have different texture structures. This composite approach allows the glass to achieve both flexibility and protection capability simultaneously through structural design rather than simply reducing thickness.

Inventive Principle:

Principle #40Composite materials

AI summary

Glass includes a first portion. The first portion includes a target texture structure and a light-transparent deformation object. The target texture structure is configured to reduce deformation stress of the glass. The light-transparent deformation object is arranged in a space of the target texture structure to cause a visual effect of the target texture structure to disappear.
