Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If centralized control is used to manage multiple luminaires, then system control capability is improved, but ease of operation deteriorates due to complex navigation through submenus and network address determination

Engineering Contradiction:

Improvesystem control capabilityVSAvoidease of operation

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system enables self-service operation where the lighting system automatically identifies and configures itself based on the user's location and identity. The control unit receives signals from portable terminals to automatically determine which luminaires to control, eliminating the need for manual navigation through submenus and network address determination.

Inventive Principle:

Principle #25Self-service

2Device complexity

If standardized lighting settings are used, then system simplicity is improved, but adaptability to individual needs deteriorates

Engineering Contradiction:

Improvesystem simplicityVSAvoidadaptability to individual needs

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The system stores multiple individualized lighting profiles in advance for different users. When a user accesses the system, their pre-stored profile is automatically loaded, providing personalized lighting settings without requiring complex real-time adjustments. This preliminary preparation enables both simplicity and adaptability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system automatically changes lighting parameters such as brightness, color temperature, and dimming profiles based on the identified user. Different users have different stored parameter sets that are automatically applied, enabling adaptability while maintaining simple operation through automatic parameter selection.

Inventive Principle:

Principle #35Parameter changes

3Ease of operation

If acoustic sensors are used for lighting control, then ease of operation is improved, but reliability deteriorates due to false detections in noisy environments

Engineering Contradiction:

Improveease of operationVSAvoidreliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system uses portable terminals (smartphones, tablets) as intermediaries between the user and the lighting system. These terminals communicate wirelessly with the control unit, providing reliable and accurate control signals without being affected by acoustic interference or false detections in noisy office environments.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Adaptability or versatility

If multiple sensors are added to enable personalized control, then adaptability is improved, but device complexity increases

Engineering Contradiction:

Improvepersonalized control capabilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system uses universal portable terminals that users already possess (smartphones, tablets) to provide personalized control. These multi-functional devices serve as both identification tools and control interfaces, eliminating the need for specialized sensors while maintaining adaptability through user-specific profiles and wireless communication.

Inventive Principle:

Principle #6Universality (Multi-functionality)
