Solution Overview

Problem

Wrist-worn electronic devices, such as smart watches, lack decorative features on their displays without obstructing the visibility of information, as they typically use only transparent layers that do not allow for aesthetic enhancements.

Innovation Solution

A display assembly comprising a transmissive and reflective layer bonded to the upper surface of the display, which presents a decorative pattern or image while remaining transparent to information displayed, and includes a texture layer and a cover layer to provide structural support and protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If only transparent layers are used on the display, then the display visibility is maintained, but the device lacks decorative features and aesthetic appeal

Engineering Contradiction:
Improvedisplay visibilityVSAvoiddecorative features
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The display assembly incorporates a multi-layer structure where each layer has specific optical properties: the first layer is transparent for display visibility, while the second layer is at least partially reflective to provide decorative appearance. This local differentiation of material properties allows simultaneous achievement of visibility and aesthetics in different regions of the display assembly.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The invention uses a composite structure combining transparent material (for display visibility) and at least partially reflective material (for decorative appearance). This composite approach integrates materials with different optical properties to resolve the contradiction between maintaining display visibility and adding decorative features.

Inventive Principle:
Principle #40Composite materials

2Adaptability or versatility

If a reflective layer is added to provide decorative appearance, then aesthetic appeal is enhanced, but the display visibility may be obstructed

Engineering Contradiction:
Improvedecorative appearanceVSAvoiddisplay visibility
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The reflective layer is positioned and configured to provide decorative appearance while maintaining display visibility. The local quality principle is applied by ensuring the reflective layer does not completely block light transmission, allowing display information to remain visible while adding aesthetic appeal through selective reflection.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The composite structure of transparent and reflective layers is designed to balance optical properties. The transparent layer ensures display visibility, while the reflective layer adds decorative appearance. The combination creates a synergistic effect where both visibility and aesthetics are achieved without mutual obstruction.

Inventive Principle:
Principle #40Composite materials

3Adaptability or versatility

If multiple layers with textures are added to enhance appearance, then decorative features are improved, but the device complexity increases

Engineering Contradiction:
Improvedecorative featuresVSAvoidlayer structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The display assembly is segmented into distinct functional layers: a transparent layer for visibility, a reflective layer for decorative appearance, and additional layers with textures. This segmentation allows each layer to be optimized for its specific function while collectively achieving enhanced decorative features. The modular structure manages complexity by dividing the system into manageable, functionally-specific components.

Inventive Principle:
Principle #1Segmentation

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution allows for a decorative and functional display that enhances the appearance of wrist-worn devices while maintaining clear visibility of information, offering a fashionable and less technical appearance without obstructing the display.

Implementation Method 1

The layer is at least partially reflective to present the decorative pattern, but is also transmissive so as avoid obstruction of any information shown on the display

Methodology Applied
Scientific EffectReflection: Reflection

Implementation Method 2

The texture layer is also positioned above the display and is configured to be transparent to light received from sources above and below the texture layer

Methodology Applied
Scientific EffectTransmission:

AI summary

An electronic device that includes a display assembly comprising a display, a texture layer, a transmissive and reflective layer, and a cover layer. The display includes an upper surface on which visual data is displayed and from which light is emitted. The texture layer includes a lower surface having a first texture with structural components and a second texture with structural components that are different from structural components of the first texture. The transmissive and reflective layer is positioned between the display and the texture layer and includes a first texture with structural components that are complementary to the structural components of the first texture of the texture layer and a second texture with structural components that are complementary to the structural components of the second texture of the texture layer. The cover layer is positioned above the texture layer and forms an upper surface of the display assembly.
