Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a visual code label (QR code) is applied to lighting devices for identification, then device identification capability is improved, but the label is susceptible to degradation and removal during handling and transport

Engineering Contradiction:
Improveidentification reliabilityVSAvoidlabel durability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent creates an optical copy of the identification data by projecting a visual code (QR code) onto the lighting device surface using light radiation. This projected code can be read by smartphones or other reading devices without requiring physical contact or attachment to the device, thereby eliminating the durability issues of physical labels while maintaining identification functionality.

Inventive Principle:
Principle #26Copying

2Reliability

If complex communication protocols are implemented for device marking, then information security is improved, but device complexity and ease of operation deteriorate

Engineering Contradiction:
Improveinformation securityVSAvoidcommunication protocol complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the identification information display function from complex communication protocols and implements it through simple optical projection. The lighting device projects visual codes containing identification data that can be directly read by smartphones using standard camera and image processing capabilities, eliminating the need for specialized communication protocols while maintaining information security through controlled projection access.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of manufacture

If physical labels are used for device marking, then manufacturing simplicity is improved, but the ability to update information without physical changes deteriorates

Engineering Contradiction:
Improvemarking application simplicityVSAvoidinformation update capability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent implements a dynamic identification system where the visual code projection can be updated in real-time through software control without any physical changes to the device. The lighting device can project different identification information as needed, providing adaptability for information updates while maintaining manufacturing simplicity since no physical labeling infrastructure is required.

Inventive Principle:
Principle #15Dynamics

AI summary

A lighting device (Fj) that can be used, for example, in the show-business and entertainment sector comprises an electrically powered light generator (LS), as well as electrical circuitry (CE) configured to produce electrical signals for driving the light generator (LS). The electrical circuitry (CE) has stored within it an electrical marker signal (RIj) uniquely associated to the lighting device (Fj), and a visual display unit (102) is coupled to the electrical circuitry (CE), where the visual display unit (102) is configured to display the electrical marker signal (RIj) as a visually recognizable optical mark, such as a QR code.
