Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a controller unit is added to enable customization and monitoring, then adaptability and ease of operation improve, but device complexity increases

Engineering Contradiction:
Improvecustomization and configurabilityVSAvoidcontroller integration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the controller unit with the lighting device array into a single integrated system. The controller is mounted on the same circuit substrate as the light source arrays, and the connector is integrated into the housing, creating a unified device that eliminates the need for separate external controller units while maintaining full customization and monitoring capabilities.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The controller unit is designed to perform multiple functions including monitoring light output, adjusting irradiance levels, detecting faults, and enabling customizable lighting configurations. The system can operate in both controlled mode (with controller) and uncontrolled mode (without controller), providing universal functionality that adapts to different user needs.

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

2Adaptability or versatility

If a separate large controller unit is used, then adaptability improves, but ease of operation and device integration worsen

Engineering Contradiction:
Improvecontrol functionalityVSAvoiduser interface accessibility
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The controller unit is integrated directly into the lighting device housing and mounted on the circuit substrate alongside the light sources. This integration eliminates the need for separate external controller units, making the control system compact, accessible, and seamlessly part of the lighting product itself.

Inventive Principle:
Principle #5Merging (Combining)

3Manufacturing precision

If manufacturing testing and configuration are performed at factory, then manufacturing precision improves, but ease of repair and adaptability worsen

Engineering Contradiction:
Improveinitial configurationVSAvoidfield servicing
Core Design Contradiction:
Manufacturing precisionVSEase of repair

Solution Approach 1:

The controller unit continuously monitors the light output of each array and compares it against expected performance parameters. When deviations indicating faults or performance degradation are detected, the controller can alert users and guide troubleshooting, enabling field servicing without requiring return to manufacturing facilities.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system enables end-users to perform basic troubleshooting and adjustments through the user interface. The controller provides diagnostic information and allows users to reconfigure lighting parameters, reducing the need for professional servicing for routine issues.

Inventive Principle:
Principle #25Self-service
