Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If indirect light measurement is used (measuring reflected light on surfaces), then environmental influences can be measured, but measurement precision is reduced and the true light source parameters cannot be accurately determined

Engineering Contradiction:
Improvephotometric parameter measurementVSAvoidenvironmental influence detection
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent introduces a mobile device as an intermediary measurement tool that can directly measure light source parameters while also detecting environmental factors. This mediator bridges the gap between precise light measurement and environmental context detection, allowing both objectives to be achieved simultaneously without the trade-off present in indirect measurement systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The measurement system is segmented into distinct functional components: the mobile device handles direct light source measurement while separately detecting environmental influences. This segmentation allows each component to optimize its measurement function independently, achieving both high precision and environmental adaptability.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If lighting parameters are not adjusted based on physiological criteria, then system complexity is reduced, but user well-being and personalized control are compromised

Engineering Contradiction:
Improvepersonalized lighting controlVSAvoidconfiguration system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system enables self-service configuration where the mobile device automatically detects light source parameters and facilitates user-defined adjustments without requiring complex manual configuration procedures. The system serves itself by providing intuitive interfaces that guide users through personalized lighting setup based on their physiological needs.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary measurement of light source parameters and environmental conditions before user configuration. This preliminary action provides the foundation for personalized lighting control, allowing the system to pre-process data and present optimized configuration options to users, thereby reducing the perceived complexity.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If address assignment requires position determination devices, then positioning accuracy is improved, but device complexity and configuration difficulty increase

Engineering Contradiction:

Solution Approach 1:

The mobile device serves multiple functions: it measures light source parameters, determines position for address assignment, and facilitates user configuration. This multi-functionality eliminates the need for separate dedicated positioning devices, reducing overall system complexity while maintaining positioning accuracy through the mobile device's integrated capabilities.

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