Solution Overview

Problem

Multidimensional codes displayed on vehicles or boats are difficult to read due to environmental factors like direct sunlight and reflected light from water surfaces, and the reading performance varies with different code readers, making it challenging to accurately interpret the information, especially when codes are divided into multiple parts.

Innovation Solution

A display controller that switchably displays multidimensional codes in multiple patterns, allowing for easier reading by adjusting the number of codes based on environmental conditions and reader performance, facilitating the representation of unique information on outboard motors or vehicles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the multidimensional code is displayed in a single large code, then the information volume is large and reading is simplified, but the code becomes difficult to read under environmental factors like direct sunlight and reflected light

Engineering Contradiction:

Improvereadability of multidimensional codeVSAvoidinfluence of direct sunlight and reflected light

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent divides a single large multidimensional code into multiple smaller multidimensional codes. Each smaller code contains a portion of the information, making them more readable under environmental factors like direct sunlight and reflected light. The reading device reads multiple smaller codes and synthesizes the complete information, resolving the contradiction between code size and readability.

Inventive Principle:

Principle #1Segmentation

2Reliability

If the multidimensional code is divided into multiple smaller codes, then the readability is improved, but the count of reading operations increases and extra labor is required

Engineering Contradiction:

Improvereadability of multidimensional codeVSAvoidreading operation labor

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent combines multiple smaller multidimensional codes into a set that can be automatically read as a group. The reading device is designed to read multiple codes in sequence and synthesize their information automatically, eliminating the need for manual intervention. This merging approach maintains the readability benefits of smaller codes while reducing the operational labor through automated synthesis.

Inventive Principle:

Principle #5Merging (Combining)

3Productivity

If a single multidimensional code is used to represent all information, then the information exchange is efficient, but the code becomes difficult to read under various environmental conditions

Engineering Contradiction:

Improveinformation exchange efficiencyVSAvoidreadability of multidimensional code

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent segments the information into multiple smaller multidimensional codes, each containing a portion of the total information. This segmentation improves readability under environmental factors while maintaining information exchange efficiency through automated reading and synthesis of the multiple codes by the reading device.

Inventive Principle:

Principle #1Segmentation

4Reliability

If multiple multidimensional codes are displayed, then the information can be read more easily, but the reading operation requires more repetitions and time

Engineering Contradiction:

Improvereadability of multidimensional codeVSAvoidreading operation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent arranges multiple smaller multidimensional codes in a predetermined sequence and format that enables automated sequential reading. The reading device can automatically read the codes in the predetermined sequence without manual intervention, and the synthesis process is pre-programmed, thereby reducing the time loss despite multiple codes being present.

Inventive Principle:

AI summary

To display a multidimensional code representing unique information of an outboard motor, a display device ensures switchably displaying the multidimensional code representing identical information by a plurality of display patterns where ease of reading is mutually different. A multidimensional code creating unit converts the unique information of the outboard motor into the multidimensional code and creates the multidimensional codes by two patterns. That is, a first multidimensional code creating unit creates a multidimensional code for a display pattern that represents the unique information of the outboard motor by the predetermined count of N (one or plural) multidimensional codes. A second multidimensional code creating unit creates a multidimensional code for a display pattern that represents the unique information of the outboard motor by the multidimensional code by reducing an information volume represented by one multidimensional code and increasing the count of multidimensional codes more than the predetermined count N.
