Solution Overview

Problem

Existing operation control devices often detect unintended operation signals, leading to erroneous operations, which compromise user intent and device operability.

Innovation Solution

An operation control device with an operation detection unit, response processing unit, and determination unit that distinguishes between intended and unintended operations by setting a determination period for valid operations, preventing unintended responses during intended operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a common operation area is used for multiple operation types, then the device complexity is reduced and ease of operation is improved, but erroneous operations are more likely to occur reducing reliability

Engineering Contradiction:

ImproveoperabilityVSAvoidoperation accuracy

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary detection of the first operation type and proactively sets a determination period before the second operation can be fully processed. This preliminary action prevents erroneous operations by blocking conflicting inputs before they can execute, resolving the contradiction between ease of operation and operation accuracy

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The determination period dynamically adjusts based on the detected first operation type, creating a time-based gating mechanism that adapts to different operational contexts. This dynamic approach maintains operational fluidity while preventing erroneous inputs, balancing ease of operation with reliability

Inventive Principle:

Principle #15Dynamics

2Measurement precision

If operation detection is made more sensitive to detect all user inputs, then measurement precision is improved, but false detection of unintended operations increases reducing reliability

Engineering Contradiction:

Improveoperation detection accuracyVSAvoidoperation validity

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The system uses feedback from the first operation detection to control the acceptance of subsequent operations. By monitoring whether a first operation has been detected and using this feedback to set or clear the determination period, the system distinguishes between intended and unintended operations, improving both detection precision and operational reliability

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The determination period acts as an intermediary mechanism between operation detection and operation execution. It mediates conflicting operation signals by temporarily blocking the second operation type when a first operation is detected, allowing the system to maintain sensitive detection while filtering out false operations through this intermediate time-based gate

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Provided is an operation control device that includes an operation detection unit that detects a first type operation and a second type operation having an operation area common to the first type operation. The operation control device further includes an operation response processing unit that performs response processing corresponding to the first type operation and the second type operation detected by the operation detection unit, and an operation determination unit that determines whether the second type operation detected by the operation detection unit is a valid operation or an invalid operation in a determination period corresponding to that the operation detection unit has detected the first type operation.
