Solution Overview

Problem

Existing operation devices struggle to accurately set output values as references for externally attached analog sticks due to variability in manufacturing processes, making it difficult to determine the center point values consistently.

Innovation Solution

The operation device includes a connection unit, a storage unit, and a processor that determine and update the output value having the highest frequency within a range assumed to be the center point, ensuring accurate reference settings for externally attached analog sticks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If output values from externally attached analog sticks are used directly, then device compatibility is improved, but measurement precision deteriorates due to manufacturing variations

Engineering Contradiction:

Improvedevice compatibilityVSAvoidcenter point output value accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system performs preliminary acquisition of multiple output values when the analog stick is at the center point before final determination. By collecting a plurality of output values in advance and analyzing their frequency distribution, the system prepares the data needed to identify the most representative center point value, thereby resolving the contradiction between compatibility and precision.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses frequency analysis of acquired output values as feedback to determine the most accurate center point value. By continuously monitoring the distribution of output values and identifying the one with the highest frequency, the system refines its determination of the center point, ensuring both compatibility with external devices and precision in measurement.

Inventive Principle:

Principle #23Feedback

2Measurement precision

If multiple output values are collected and analyzed, then measurement precision is improved, but loss of time increases due to additional processing

Engineering Contradiction:

Improvecenter point output value accuracyVSAvoidtime for acquiring and processing output values

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system performs self-calibration by automatically analyzing the frequency distribution of acquired output values and determining the center point value without requiring external intervention or complex processing. This self-service approach minimizes time loss while maintaining high measurement precision through automated frequency-based determination.

Inventive Principle:

Principle #25Self-service

AI summary

Provided is a controller 6 including a storage unit that stores an output value determined in advance and output from an externally-attached analog stick when the analog stick is at a center point. The controller 6 determines, in a case in which a plurality of the output values from the analog stick are values within a range in which the analog stick is assumed to be at the center point, an output value having a highest frequency among the plurality of output values. The controller 6 updates, on the basis of the determined output value, the output value stored in the storage unit.
