Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If OLED modules are arranged in a fixed matrix configuration, then manufacturing and assembly are simplified, but flexibility in shape and size customization is reduced

Engineering Contradiction:
Improveassembly simplicityVSAvoidshape and size flexibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The OLED display is divided into multiple independent modules arranged in a matrix, where each module can be independently packaged and connected through bus circuits. This segmentation allows the display to be cut and reconfigured into different shapes while maintaining functionality, as each module operates independently yet contributes to the overall display.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bus circuit configuration enables dynamic reconfiguration of the OLED modules. By connecting modules in a matrix with bus circuits that can be selectively activated, the display can adapt to different shape and size requirements without requiring complete redesign, thus providing both manufacturing simplicity and shape flexibility.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If OLED modules are cut to create custom shapes, then adaptability to different spaces is improved, but service life and functionality of individual modules may be compromised

Engineering Contradiction:
Improvecustom shape capabilityVSAvoidmodule service life
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

Each OLED module is independently packaged with its own protective structure before being arranged in the matrix. This independent packaging ensures that when the display is cut to create custom shapes, only the necessary modules are removed or deactivated, while the remaining modules maintain their integrity and service life without being affected by the cutting process.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bus circuit design includes redundant connection paths and protective structures that are prepared in advance. When modules are cut or removed for custom shaping, the pre-established bus circuit connections ensure that power and signal distribution remains stable, preventing damage to remaining modules and maintaining their service life.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Power

If a mesh structure bus circuit is used to connect OLED modules, then power distribution and signal transmission are improved, but device complexity increases

Engineering Contradiction:
Improvepower distribution efficiencyVSAvoidcircuit structure complexity
Core Design Contradiction:
PowerVSDevice complexity

Solution Approach 1:

The bus circuits serve multiple functions simultaneously: they provide power distribution, transmit control signals, and enable communication between modules. By using a standardized mesh structure for all modules, the same circuit design can be applied regardless of the display shape or size, reducing overall complexity despite the interconnected nature of the mesh.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The mesh bus circuit is divided into modular segments that correspond to the OLED module arrangement. Each segment can be independently configured and activated, allowing the system to scale from simple to complex configurations based on requirements, thus managing complexity while maintaining efficient power and signal distribution.

Inventive Principle:
Principle #1Segmentation

AI summary

An organic light emitting diode (OLED) light source device is provided, including a lower substrate, a plurality of OLED modules disposed on the lower substrate and arranged in a matrix, a bus circuit surrounding the OLED modules to form a mesh structure and connecting the OLED modules in parallel, and an upper substrate disposed on the OLED modules and the bus circuit. The bus circuit connects the OLED modules in parallel. Therefore, the OLED light source device can be arbitrarily cut into different shapes, and its service life and light emitting performance are not affected by the cutting.
