Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If voice control is implemented using external devices and internet connections, then voice command recognition capability is achieved, but device complexity and cost increase

Engineering Contradiction:
Improvevoice control capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent integrates the voice recognition circuit directly into the lighting device, merging previously separate functions (voice recognition and lighting control) into a single unified system. This eliminates the need for external voice input devices and internet connections, thereby reducing system complexity while maintaining voice control capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The lighting device performs voice recognition autonomously using its own integrated voice recognition circuit, without requiring external services or internet connectivity. The device processes voice commands locally and executes them directly, enabling self-service operation that reduces system complexity.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If voice control is implemented using external devices and internet connections, then voice command recognition capability is achieved, but cost increases

Engineering Contradiction:
Improvevoice control capabilityVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By combining voice recognition and lighting control into a single integrated device, the patent eliminates the need for separate external voice input devices and internet infrastructure. This consolidation reduces component costs and simplifies manufacturing processes while maintaining full voice control functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent employs a cost-effective voice recognition circuit that processes commands locally without requiring expensive internet connectivity infrastructure. This approach uses simpler, more affordable components that can be manufactured at lower cost while achieving the same functional outcome.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Adaptability or versatility

If voice commands are processed by central components connected to the internet, then voice recognition is achieved, but misinterpretation occurs in multi-device environments

Engineering Contradiction:
Improvevoice control functionalityVSAvoidvoice command accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent enables each lighting device to independently process voice commands using its own integrated voice recognition circuit. This local processing ensures that only the intended device responds to voice commands, eliminating misinterpretation in multi-device environments. Each device has the quality of autonomous voice recognition capability.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

Each lighting device performs voice recognition autonomously without relying on central components or internet-based processing. The device independently captures, recognizes, and executes voice commands, ensuring accurate response only from the targeted device even in environments with multiple lighting devices.

Inventive Principle:
Principle #25Self-service
