Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional lighting devices are used, then general illumination is provided, but the ability to identify objects with specific wavelength absorption, reflection, or refraction properties is inadequate
Solution Approach 1:
The lighting device segments the light spectrum into multiple discrete wavelength blocks (e.g., blue, cyan, green, yellow-green, yellow, orange, red). Each wavelength block can be independently controlled and emitted in alternating sequences, allowing selective emphasis on specific wavelength ranges that match the absorption, reflection, or refraction properties of target objects.
Solution Approach 2:
The device employs periodic alternation between different wavelength blocks with specific duty cycles. The vivid wavelength blocks are emitted during first time intervals with higher intensity, while dulling wavelength blocks are emitted during second time intervals with lower intensity. This periodic action creates a coherent light beam that emphasizes objects with specific wavelength properties while maintaining overall illumination.
Solution Approach 3:
The system dynamically adjusts the duty cycles and intensity levels of different wavelength blocks based on user selection. Users can select from multiple preset configurations (e.g., blood identification, foliage identification, general purpose) that optimize the alternating pattern for specific detection needs or visual acuity requirements, making the device adaptable to varying conditions.
2Measurement precision
If single wavelength lighting is used, then detection of specific objects is improved, but adaptability to different detection needs and user requirements is reduced
Solution Approach 1:
The lighting device incorporates multiple light emitting diodes emitting different wavelength blocks within a single device. By alternating between these wavelength blocks with controllable duty cycles, the device provides multiple functions: general illumination, blood identification, foliage identification, and other object detection modes, making it universally applicable to various detection needs.
Solution Approach 2:
The system changes operational parameters (wavelength block selection, duty cycle percentages, intensity levels, and alternating sequences) to optimize performance for different detection scenarios. Users can select from preset configurations or adjust parameters to match their specific visual acuity and detection requirements, enabling the same device to adapt to diverse conditions.

Data Source
AI summary
A lighting device is disclosed operating a vivid source having a first duty cycle and a dulling source with second duty cycle. The vivid source and the dulling source operate at alternating time intervals where the intensity of one wavelength segment or block is emphasized in the vivid source and absent or de-emphasized in the dulling source. The operation provides the user with an emphasis on objects that reflect or absorb the emphasized wavelength segment.
