Solution Overview

Problem

Existing navigation light-signaling devices are inadequate for clearly indicating a navigation route, especially in poor visibility conditions, and are not energy-independent, limiting their effectiveness in ensuring navigation safety.

Innovation Solution

A light-signaling device with a directional and fixed laser or LED light beam, integrated with a power supply such as solar panels, and adaptable fastenings for installation on dolphins, which can be used in conjunction with multiple devices to create a visible route by directing light beams between spaced-out units.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If traditional light-signaling devices use wide omni-directional light beams, then the light coverage area is improved, but the ability to clearly indicate a specific navigation route is worsened

Engineering Contradiction:
Improvelight coverage areaVSAvoidroute indication clarity
Core Design Contradiction:
Area of stationary objectVSLoss of information

Solution Approach 1:

The patent applies local quality by using multiple light sources with different beam characteristics in specific positions. Narrow directional beams are positioned to define the route path, while wider beams provide general area illumination. This spatial differentiation of light beam properties enables both route clarity and area coverage simultaneously.

Inventive Principle:
Principle #3Local quality

2Device complexity

If light-signaling devices are installed on existing structures like dolphins, then the installation complexity is reduced, but the energy independence is worsened

Engineering Contradiction:
Improveinstallation complexityVSAvoidenergy independence
Core Design Contradiction:
Device complexityVSUse of energy by moving object

Solution Approach 1:

The patent implements universality by designing a hybrid power system that can operate in multiple modes. The device can function with external power when available (reducing installation complexity by utilizing existing infrastructure), and switch to battery power with solar recharging when external power is unavailable (achieving energy independence). This multi-functional power architecture resolves the contradiction between installation simplicity and energy autonomy.

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

3Loss of information

If multiple light-signaling devices are spaced out to define a route, then the route indication effectiveness is improved, but the energy consumption is worsened

Engineering Contradiction:
Improveroute indication effectivenessVSAvoidenergy consumption
Core Design Contradiction:
Loss of informationVSUse of energy by moving object

Solution Approach 1:

The patent applies periodic action by implementing intermittent lighting modes and duty-cycled operation. Instead of continuous illumination, the light sources operate in periodic intervals or respond to detection signals, reducing overall energy consumption while maintaining effective route indication during critical periods. This temporal modulation of light emission balances route visibility with energy conservation across multiple devices.

Inventive Principle:
Principle #19Periodic action
