Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate light therapy devices are used for different treatment objectives, then each device can be optimized for its specific therapeutic function, but the cost, time, and user convenience deteriorate due to requiring multiple devices

Engineering Contradiction:
Improvetherapeutic function varietyVSAvoiduser convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The OLED display device is designed to perform multiple functions: it can operate as a conventional display device showing images and videos, and simultaneously function as a light therapy device for treating skin conditions. The display panel itself serves as the light source for therapy, eliminating the need for separate dedicated therapy devices and improving user convenience while maintaining versatility

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

2Adaptability or versatility

If multiple separate light therapy devices are used for different treatment objectives, then each device can be optimized for its specific therapeutic function, but the cost increases due to purchasing multiple devices

Engineering Contradiction:
Improvetherapeutic function varietyVSAvoiddevice quantity
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The invention merges the display function and light therapy function into a single integrated device. The OLED display panel serves dual purposes: displaying visual content and emitting therapeutic light. This consolidation reduces the total number of devices from multiple separate therapy devices to one unified device, thereby reducing cost while maintaining the ability to provide various therapeutic functions

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If the display device emits light for therapy, then therapeutic benefits are achieved, but the display performance and image quality may deteriorate

Engineering Contradiction:
Improvelight emission capabilityVSAvoiddisplay brightness
Core Design Contradiction:
Adaptability or versatilityVSIllumination intensity

Solution Approach 1:

The device dynamically switches between display mode and light therapy mode. When used for therapy, the display is turned off or dimmed while the OLED emits therapeutic light at appropriate intensities. When used for display purposes, the device operates as a conventional high-brightness display. This dynamic operation ensures optimal performance for whichever function is currently active, preventing degradation of either display quality or therapy effectiveness

Inventive Principle:
Principle #15Dynamics
