Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single display mode is used, then device complexity is reduced, but adaptability to different lighting conditions deteriorates

Engineering Contradiction:

Improvedisplay structureVSAvoidadaptability to lighting conditions

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The display system incorporates dynamic switching capability between reflective and transmissive modes, allowing it to adapt to different lighting conditions. This dynamic behavior is achieved through controllable light sources and switchable optical paths, enabling the system to optimize performance across varying environmental conditions

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system integrates multiple display modes (reflective and transmissive) within a single unified structure, allowing one device to perform multiple functions. This multi-functionality is achieved through shared optical components and coordinated control mechanisms that enable seamless switching between modes

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Use of energy by moving object

If reflective mode is used, then energy consumption is reduced, but visibility in low-light conditions deteriorates

Engineering Contradiction:

Improveenergy consumptionVSAvoidvisibility in low-light conditions

Core Design Contradiction:

Use of energy by moving objectVSIllumination intensity

Solution Approach 1:

The display system dynamically switches between reflective and transmissive modes based on ambient light conditions. In bright environments, it operates in energy-efficient reflective mode, while in low-light conditions it transitions to transmissive mode with active illumination, thereby optimizing the balance between energy consumption and visibility

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system combines reflective and transmissive display capabilities in one device, allowing it to select the appropriate mode based on lighting conditions. This multi-functionality enables the system to maintain visibility across all lighting conditions while minimizing energy consumption by using reflective mode when possible

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Illumination intensity

If transmissive mode is used, then visibility in low-light conditions is improved, but energy consumption increases

Engineering Contradiction:

Improvevisibility in low-light conditionsVSAvoidenergy consumption

Core Design Contradiction:

Illumination intensityVSUse of energy by moving object

Solution Approach 1:

The display system dynamically activates transmissive mode only when ambient light conditions warrant it, such as during nighttime or in dimly lit environments. During daytime, it switches to reflective mode to conserve energy, thereby optimizing the balance between visibility and energy consumption based on real-time environmental conditions

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system integrates both transmissive and reflective modes in a single device, allowing it to select the most appropriate mode based on lighting conditions. This multi-functionality enables the system to provide excellent visibility in low-light conditions when needed while minimizing energy consumption during daytime operation

Inventive Principle:

Principle #6Universality (Multi-functionality)
