Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If high-performance processors and large memory are used to accurately observe small, irregularly changing waves, then measurement precision is improved, but device complexity and hardware resource constraints increase

Engineering Contradiction:
Improvewave observation accuracyVSAvoidhardware resource constraints
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent changes the sampling frame rate parameter to 100 FPS, which is optimized to capture small, irregularly changing waves effectively. This parameter adjustment achieves accurate wave observation without requiring excessively high-performance processors or large memory, thus resolving the contradiction between measurement precision and device complexity

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies partial action by using a frame rate of 100 FPS, which is sufficient to capture the essential characteristics of small waves without over-sampling. This avoids the need for extremely high-performance hardware while still achieving accurate measurement of wave interference phenomena

Inventive Principle:
Principle #16Partial or excessive action

2Measurement precision

If the frame rate is increased to capture small, irregularly changing waves, then measurement precision is improved, but use of energy increases

Engineering Contradiction:
Improvewave observation accuracyVSAvoidenergy consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent optimizes the frame rate parameter to 100 FPS, which balances the need for accurate wave observation with energy consumption constraints. This parameter setting is sufficient to capture small, irregularly changing waves without requiring excessive energy, thus resolving the contradiction between measurement precision and energy use

Inventive Principle:
Principle #35Parameter changes

3Illumination intensity

If laser light is used to illuminate the water surface, then illumination intensity is improved, but loss of substance increases due to reflected light

Engineering Contradiction:
Improvewater surface illuminationVSAvoidlaser light loss
Core Design Contradiction:
Illumination intensityVSLoss of substance

Solution Approach 1:

The patent replaces expensive laser light with free natural light (sunlight), which is abundant and does not suffer from reflection losses. This substitution eliminates the problem of laser light loss while still providing sufficient illumination intensity for wave observation, resolving the contradiction between illumination intensity and substance loss

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

AI summary

A planing boat sailing assisting device includes a sensor and a data processing apparatus mounted on a planing boat. The sensor is configured to obtain not reflected light of laser light applied to a water surface but natural visible light or infrared light coming from the water surface obliquely below the sensor, by using a global shutter. The data processing apparatus obtains data obtained by the sensor, at a frame rate of not lower than FPS and not higher than 100 FPS, and generates wave data related at least to a height of a wave and a time until arrival of the wave based on sets of data obtained by the sensor, at least once every second. The data processing apparatus outputs the generated wave data to at least one of a wave display or a controller.
