Solution Overview

Problem

Existing image display devices for slot machines face challenges in manufacturing curved edge portions without flexible materials, leading to issues like afterimages, high costs, and discontinuous screen displays due to non-flexible materials and physical limitations in shaping.

Innovation Solution

An integrated image display device is created by connecting a flexible sub-image display device to the side edge portion of a non-flexible main image display device, with the sub-device formed in a curved shape to minimize black mask areas and enhance visibility, using a flexible printed circuit board for touch traces and indium tin oxide for transparency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If a flexible material (e.g., plastic OLED) is used to manufacture a curved edge portion, then the bending property is improved, but afterimage occurs and product cost increases

Engineering Contradiction:
Improvecurved edge portionVSAvoidafterimage
Core Design Contradiction:
ShapeVSReliability

Solution Approach 1:

The display device is divided into a main display body and a separate curved edge display portion. The curved edge portion can be segmented into multiple small display units that are connected to the main display body, allowing the curved shape to be achieved without using flexible materials that cause afterimage effects.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the display device use different materials and structures. The main display body uses conventional non-flexible materials for high reliability, while the edge portion uses a structure that achieves curvature through geometric design rather than flexible materials, thus avoiding afterimage while maintaining local curved shape.

Inventive Principle:
Principle #3Local quality

2Shape

If a flexible material (e.g., plastic OLED) is used to manufacture a curved edge portion, then the bending property is improved, but product cost increases

Engineering Contradiction:
Improvecurved edge portionVSAvoidproduct cost
Core Design Contradiction:
ShapeVSEase of manufacture

Solution Approach 1:

The curved edge display is segmented into multiple standard display units that can be manufactured using conventional processes. These standardized modules can be produced at lower costs compared to custom flexible displays, and they can be assembled into the curved edge configuration through standard manufacturing techniques.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of using expensive flexible display materials, the invention uses conventional display units that can be manufactured at lower cost. The curved shape is achieved through the arrangement and connection of these standard units rather than through expensive flexible materials, thus reducing overall product cost.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Ease of manufacture

If non-flexible image display devices are connected to an edge portion, then manufacturing cost is reduced and afterimage is avoided, but image continuity is disrupted due to black mask areas

Engineering Contradiction:
Improvemanufacturing costVSAvoidimage continuity
Core Design Contradiction:
Ease of manufactureVSShape

Solution Approach 1:

The edge portion is designed with a curved shape that allows the display units to be arranged in a continuous visual flow. The curvature of the edge portion helps to minimize the visibility of black mask areas by angling the display units in a way that reduces gaps and discontinuities, thus improving image continuity while maintaining the use of non-flexible materials.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The black mask areas are minimized by optimizing the local arrangement and orientation of display units at the edge portion. The display units are positioned and angled to reduce the visibility of black masks, creating a more continuous image appearance while still using conventional non-flexible display technology.

Inventive Principle:
Principle #3Local quality

4Ease of manufacture

If non-flexible image display devices are connected to an edge portion, then manufacturing cost is reduced, but visibility from lateral sides is reduced due to small bent section

Engineering Contradiction:
Improvemanufacturing costVSAvoidvisibility from lateral sides
Core Design Contradiction:
Ease of manufactureVSIllumination intensity

Solution Approach 1:

The curved shape of the edge portion is optimized to enhance visibility from lateral sides. By designing the edge with an appropriate curvature radius and angle, the display units are oriented to reflect light towards lateral viewing positions, improving visibility from multiple angles while maintaining the use of cost-effective non-flexible materials.

Inventive Principle:
Principle #14Spheroidality (Curvature)
