Boat Touch Panel Display for Simultaneous Speed and Acceleration Control

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current personal watercraft systems require operators to switch between speed and acceleration settings, limiting the ability to set both values simultaneously while visually recognizing both screens, which complicates the operation and reduces convenience.

Innovation Solution

A system with a single touch panel display that shows speed and acceleration setting images side by side, allowing operators to set speed and acceleration values independently without switching screens, using a single touch panel that receives inputs on both settings simultaneously, and includes a locking mechanism to restrict unauthorized changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the display switches between speed setting screen and acceleration setting screen sequentially, then the operator can set speed and acceleration values, but the operator cannot visually recognize both screens at the same time and cannot set both values simultaneously

Engineering Contradiction:

Improveability to set speed and acceleration simultaneously while visually recognizing both screensVSAvoidscreen switching mechanism and sequential setting procedure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent transitions from sequential temporal display (one screen at a time) to simultaneous spatial display (multiple screens side by side). The display unit presents the speed setting screen and acceleration setting screen horizontally adjacent to each other on a single display device, allowing the operator to view and set both parameters simultaneously without screen switching.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If separate screens are provided for speed and acceleration settings, then each parameter can be set independently, but the number of components and system complexity increases

Engineering Contradiction:

Improveindependent setting capability for speed and accelerationVSAvoidnumber of display components and system structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple display functions into a single display unit. The speed setting screen and acceleration setting screen are merged and presented side by side on the same display device, eliminating the need for separate display components while maintaining independent setting capabilities for both parameters.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single display unit performs multiple functions by simultaneously displaying both the speed setting screen and acceleration setting screen. This multi-functional display device allows the operator to access and set different parameters (speed and acceleration) through one unified interface rather than requiring separate dedicated displays for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A small boat includes an engine, a display that displays a speed setting image of a boat body and an acceleration setting image of the boat body side by side, an operator including a speed setting operator through which an operation of setting a speed set value is received and an acceleration setting operator through which an operation of setting an acceleration set value is received, and an engine controller that controls the engine based on the operations received by the operator.
