Innovation Solution

A portable light system that uses a light source to modulate data by varying its intensity, allowing data transmission without the need for external openings, utilizing a processor to control the light source and memory for data storage, and a receiver to decode the modulated light for data retrieval.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If additional data ports or connectors are added to the light housing for data transmission, then data transmission capability is improved, but the number of seals and openings increases which worsens reliability and increases contamination risk

Engineering Contradiction:
Improvedata transmission capabilityVSAvoidlight seal reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent replaces mechanical data transmission systems (connectors, ports, wires) with an optical communication system. The light source itself is modulated to transmit data optically, eliminating the need for additional mechanical openings or connectors in the housing, thereby maintaining seal integrity and reliability while enabling data transmission capability

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The light source serves dual functions: providing illumination and transmitting data through modulation. By making the light source multi-functional, the patent eliminates the need for separate data transmission components that would require additional openings and seals, thus resolving the contradiction between data transmission capability and seal reliability

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

2Adaptability or versatility

If additional seals are added to the light housing for data ports, then data transmission capability is improved, but device complexity and cost increase

Engineering Contradiction:
Improvedata transmission capabilityVSAvoidseal complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces mechanical data transmission systems requiring additional seals with an optical modulation system. The existing light source is controlled to vary its intensity in accordance with data, eliminating the need for additional sealed openings or connector terminals, thereby reducing device complexity and cost while maintaining data transmission capability

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If connector terminals are added for data transmission, then data transmission capability is improved, but contamination risk and safety hazards increase in hazardous environments

Engineering Contradiction:
Improvedata transmission capabilityVSAvoidcontamination and sparking risk
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces electrical connector terminals with an optical communication system using the light source. This eliminates exposed electrical contacts that could accumulate contamination or create sparking hazards in combustible environments, while still enabling data transmission through light modulation that can be detected by external receivers

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
