Solution Overview

Problem

Conventional character string input apparatuses fail to prevent the input of inappropriate expressions when connecting words, as they only determine connectivity without evaluating the appropriateness of the resulting character string.

Innovation Solution

A computer-readable storage medium with a program that functions as character input reception, option character string obtaining, preceding/following identification, and fixed character string determination means to prevent inappropriate expressions by determining which option character strings are connectable to preceding or following characters, and only allowing those as fixed inputs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the apparatus displays all option character strings corresponding to input characters, then the user can select from more choices, but inappropriate expressions may be fixedly inputted

Engineering Contradiction:

Improveselection flexibilityVSAvoidinappropriate expression input

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary determination of connectability between character strings before displaying options to the user. By pre-evaluating whether option character strings can be properly connected with surrounding characters using connection information, inappropriate expressions are filtered out before the user sees the options, thus preventing harmful inputs while maintaining selection flexibility

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Connection information acts as an intermediary mechanism between the input characters and the option character strings. This intermediary layer evaluates the connectability between characters and option strings, allowing the system to selectively permit or block certain combinations without directly interfering with user choice, thus resolving the contradiction between versatility and appropriateness

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If the apparatus determines connectivity based only on option character strings, then the input process is simple, but inappropriate combinations with preceding or following characters are not prevented

Engineering Contradiction:

Improvedetermination processVSAvoidexpression appropriateness

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The system extends the determination process from a single dimension (connectivity between input character and option string) to multiple dimensions by incorporating connection information that evaluates relationships with preceding and following characters. This multi-dimensional approach maintains relatively simple processing while significantly improving reliability in preventing inappropriate expressions

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Productivity

If all option character strings are allowed as fixed inputs, then input efficiency is high, but inappropriate expressions are formed

Engineering Contradiction:

Improveinput efficiencyVSAvoidinappropriate expression formation

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system extracts and removes option character strings that would form inappropriate expressions with surrounding characters, based on connection information evaluation. By selectively taking out inappropriate options from the available choices, the system maintains high input efficiency for appropriate expressions while preventing harmful expression formation

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A game apparatus, when receiving an input of an input character by a user, obtains and displays option character strings corresponding to the input character. The option character strings displayed here are option character strings that are connectable to a word preceding the input character. Displayed as the option character strings in this manner are only character strings, each of which does not form an inappropriate expression when connected to the word preceding or following the input character. When the user has selected an option character string from these option character strings, the game apparatus determines the option character string to be a fixed character string, and displays and stores the fixed character string.
