Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If OLED light source devices use fixed specifications, then manufacturing and installation are simplified, but flexibility in size and shape is limited

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidflexibility in size and shape
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The OLED light source device is divided into multiple independently packaged OLED modules arranged in a matrix pattern. Each module has its own package frame structure and can be independently cut without affecting the service life of other modules. This segmentation enables the device to be cut into various shapes and sizes while maintaining manufacturing simplicity through standardized module designs.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If OLED modules are cut into various shapes, then design versatility is enhanced, but module service life may be compromised

Engineering Contradiction:
Improvedesign versatilityVSAvoidmodule service life
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

Each OLED module is independently packaged with a package frame structure that provides mechanical protection and environmental sealing. This independent packaging ensures that cutting between modules does not expose the OLED chips to moisture or physical damage, maintaining service life even when the overall device is cut into various shapes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The package frame structure provides localized protection at critical interfaces where cutting may occur. The frame reinforces the edges and sealing points of each module, ensuring that the local structural integrity is maintained during and after the cutting process, thereby preserving the reliability of the OLED modules.

Inventive Principle:
Principle #3Local quality

3Power

If sensing electrodes are used for wireless power transmission, then power provision is enhanced, but device complexity increases

Engineering Contradiction:
Improvepower provision capabilityVSAvoiddevice complexity
Core Design Contradiction:
PowerVSDevice complexity

Solution Approach 1:

The sensing electrodes serve dual functions: they are part of the OLED module electrical structure and simultaneously function as receiving antennas for wireless power transmission. This multi-functionality eliminates the need for separate power receiving components, reducing device complexity while maintaining enhanced power provision capability.

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

Solution Approach 2:

The electrical connection structure of the OLED modules is merged with the wireless power receiving antenna structure. The sensing electrodes that connect the OLED chips to the power source are integrated with the electromagnetic coupling elements needed for wireless power transfer, combining two functions into a single structural element and simplifying the overall device architecture.

Inventive Principle:
Principle #5Merging (Combining)
