Marine Electronic Device Drawn Zone Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing marine electronic devices require time-consuming and frustrating manual adjustments to set guard zones, especially when non-square shapes are needed.
Innovation Solution
A marine electronic device with a touch screen interface that allows users to define a drawn zone by creating a continuous touch pattern on the screen, enabling quick and efficient zone creation and updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment using moveable arrows and dragging corners is used to set guard zones, then the zone can be adjusted to desired shape and position, but the process becomes time-consuming and frustrating
Solution Approach 1:
The patent replaces the mechanical drag-and-drop interface with a touch-based drawing system. Users directly draw zone boundaries by touching and dragging the screen, which the system interprets to create the guard zone. This substitution of the interaction mechanism dramatically reduces the steps required to create a zone while maintaining precision.
Solution Approach 2:
The system automatically generates the guard zone geometry based on the user's touch pattern. Once the user draws the desired shape by touching at key points, the system self-calculates and creates the enclosed zone without requiring manual parameter input or complex adjustments, making the process intuitive and fast.
2Ease of operation
If manual adjustment methods are used, then zone positioning is possible, but expertise in generating the zone is required
Solution Approach 1:
The complex mechanical process of positioning zones using arrows and corner-dragging is replaced with a simple touch-drawing gesture. Users naturally draw the zone shape they want, and the system handles all the geometric calculations and zone creation logic, eliminating the need for users to understand complex positioning mechanisms.
Solution Approach 2:
The system captures the user's touch pattern directly as the zone definition. Instead of requiring users to manipulate abstract control elements, the system copies the user's natural drawing gesture and converts it into the precise zone geometry, making the process as intuitive as drawing on paper.
3Productivity
If traditional guard zone methods are used, then zone monitoring is possible, but the process is frustrating and inefficient
Solution Approach 1:
The inefficient mechanical adjustment process is replaced with a direct touch-drawing interface. Users draw the zone shape in a single continuous gesture, and the system immediately creates and activates the guard zone with monitoring functionality, dramatically improving both setup efficiency and user experience.
Solution Approach 2:
The system prepares and activates the guard zone monitoring functionality automatically as the user completes their drawing gesture. The zone is created and monitoring is initiated in one continuous action, eliminating the need for separate configuration steps and providing immediate productivity benefits.

AI summary
Example devices, systems and methods are provided for operating a marine electronic device for a watercraft to determine a drawn zone based on a user input. Some example systems include a user interface comprising a touch screen, a processor and a memory having computer program code stored thereon. The marine electronic device is configured to cause one of a chart, a sonar image, or a radar image to be displayed on the touch screen and to receive, via the touch screen, a user input defining a continuous touch pattern directed to the one of the chart, the sonar image, or the radar image. The marine electronic device is further configured to determine, based on the user input, a drawn zone of the one of the chart, the sonar image, or the radar image and determine a drawn zone functionality associated with the user input.
