Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional lighting systems with simple on/off control are used, then the device complexity is low, but the ability to control fish behavioral and physiological responses is insufficient
Solution Approach 1:
The patent introduces an intermediary conversion unit that translates high-level fish response instructions into detailed lighting control signals. This mediator handles the complexity of spectral and intensity control, while users interact with simple response-based commands, resolving the contradiction between control capability and system complexity.
Solution Approach 2:
The system performs self-service by automatically converting desired fish responses into optimized lighting parameters without requiring user expertise in photobiology or lighting control. The conversion unit autonomously determines the appropriate spectral power distribution and intensity patterns to achieve the specified fish behavioral or physiological outcomes.
2Ease of operation
If standardized data format is implemented, then ease of operation improves, but flexibility to incorporate new insights may be limited
Solution Approach 1:
The standardized data format is designed to be dynamic and extensible, allowing new fish response types and lighting parameters to be incorporated without changing the fundamental interface structure. The system can adapt to new scientific insights by updating the conversion algorithms and data formats while maintaining user-friendly operation through consistent interaction patterns.
3Measurement precision
If LED lighting with variable intensity and spectrum is used, then the ability to target specific fish responses improves, but the device complexity and control requirements increase
Solution Approach 1:
The conversion unit serves as an intermediary that handles the complex task of translating simple fish response targets into detailed LED control signals. It manages the spectral power distribution calculations and intensity modulation requirements, shielding users from the underlying complexity while enabling precise targeting of fish physiological and behavioral responses.
Solution Approach 2:
The system controls LED parameters (spectral power distribution, intensity, timing) dynamically to achieve precise fish response targeting. By programmatically adjusting these parameters based on the desired fish outcome, the system achieves high measurement precision in controlling fish responses without requiring complex manual intervention.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enhances fish cultivation productivity by providing a user-friendly interface for controlling light intensity and spectrum, improving behavioral and physiological responses, and allowing for easy updates and compatibility with evolving fish care practices.
Implementation Method 1
LED light sources can have a narrow and well-defined spectral output, the light intensity can be varied over a broad range, and different LED light sources of different colors can be combined offering control of spectral output
Implementation Method 2
The lighting is for example placed in a sea cage or above a fresh water tank. Generally, known systems have lights which are either on or off, without any dimming control. The artificial light is for example specifically used for prevention of fish maturation in marine water applications and used for smoltification (behavioral) processes in fresh water applications.
Data Source
AI summary
A fish lighting system has an input interface (10) which receives instructions corresponding to a desired fish behavioral and/or physiological response (12). This is converted into a lighting control signal (RGB, t) for driving a lighting arrangement (18), with the intensity and color of the output from the lighting arrangement selected to obtain the desired fish behavioral and/or physiological response.
