Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional video recording devices may execute unnecessary processing due to erroneous operations of touch panels or buttons when taken out of a vehicle, leading to inefficiencies.

Innovation Solution

A video recording device equipped with a data acquisition unit to detect the action of being taken out of a vehicle, a determination unit to assess if conditions are met, and a control unit to disable device operations when predetermined conditions are detected, thereby preventing erroneous interface operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the video recording device is made portable and removable from the vehicle, then the versatility and adaptability are improved, but erroneous operations occur when the device is taken out

Engineering Contradiction:

ImproveportabilityVSAvoidoperation accuracy

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary detection of the removal state before allowing normal operations. The determination unit checks whether the device is in the removed state before enabling interface operations, preventing erroneous operations from occurring in the first place

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors the removal state through sensors and provides feedback to the control unit. Based on this feedback, the control unit dynamically enables or disables interface operations, ensuring that operations are only permitted when the device is properly installed

Inventive Principle:

Principle #23Feedback

2Ease of operation

If interface operations are always enabled, then the ease of operation is improved, but unnecessary processing occurs when the device is removed

Engineering Contradiction:

Improveinterface accessibilityVSAvoidprocessing efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The interface operation state is made dynamic rather than static. The control unit changes the operational state of the interface based on the real-time removal state detected by the sensors, allowing full operation when installed and preventing operations when removed

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The harmful function of interface operations is extracted or removed when the device is in the removed state. The control unit disables touch panel and button operations specifically when removal is detected, eliminating unnecessary processing while maintaining functionality when properly installed

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A video recording device includes a data acquisition unit configured to acquire data indicating a result of detecting a phenomenon associated with an action of taking the video recording device out from a vehicle, a determination unit configured to determine whether the result indicated by the data meets a predetermined condition, and a control unit configured to control the video recording device such that an operation for an interface used to operate the video recording device is disabled when the result indicated by the data is determined to meet the predetermined condition.
