Solution Overview

Problem

Portable display devices can accidentally turn on when carried in a bag, leading to unnecessary power consumption due to accidental pressing of the power button, which existing technologies have not effectively addressed.

Innovation Solution

A display device with a power key and processor that determines the power supply type and displays a power-on continuation confirmation screen when a battery power supply is detected, requiring user confirmation before continuing to operate, thereby preventing unintended startup.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the display device automatically starts when the power button is pressed, then the ease of operation is improved, but the reliability deteriorates due to accidental startup when carried in a bag

Engineering Contradiction:
Improvepower button responsivenessVSAvoidaccidental startup prevention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary detection of power supply type (battery vs. AC adapter) before executing the power-on operation. When a battery is detected, the system preemptively displays a confirmation screen to prevent accidental startup, while allowing immediate startup when an AC adapter is detected.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system provides feedback to the user through a confirmation screen that asks whether to really turn on the power. This feedback loop allows the user to confirm or cancel the power-on operation based on the detected power supply type, preventing accidental startup while maintaining intentional operation capability.

Inventive Principle:
Principle #23Feedback

2Reliability

If the display device requires user confirmation before starting, then the reliability improves by preventing accidental startup, but the ease of operation deteriorates due to additional confirmation steps

Engineering Contradiction:
Improveaccidental startup preventionVSAvoidpower button responsiveness
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The confirmation requirement is applied locally and selectively based on the detected power supply type. Confirmation is only required when a battery is detected, not when an AC adapter is detected, making the operation flow adaptive to the specific power supply context rather than uniformly requiring confirmation in all cases.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system dynamically adjusts the power-on flow based on the detected power supply type. The confirmation screen is conditionally displayed only when necessary (battery power), creating a dynamic operation flow that adapts to the power supply situation rather than following a fixed sequence.

Inventive Principle:
Principle #15Dynamics

3Productivity

If the light source is turned on immediately when the power button is pressed, then the productivity is improved, but the loss of energy increases due to unnecessary power consumption during accidental startup

Engineering Contradiction:
Improvestartup speedVSAvoidpower consumption
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The system performs preliminary detection of the power supply type before turning on the light source. This preliminary action allows the system to prevent unnecessary light source activation when a battery is detected and the user does not confirm the power-on operation, thereby avoiding energy waste while maintaining quick startup capability when appropriate.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The confirmation screen provides feedback that pauses the light source activation process until the user responds. This feedback mechanism prevents energy consumption by the light source during accidental startup scenarios while allowing immediate activation when the user intentionally confirms power-on or when an AC adapter is detected.

Inventive Principle:
Principle #23Feedback

AI summary

A display device includes a power key, and at least one processor that executes following: determination processing that determines, when turning on a light source in response to a user's operation on the power key, whether a power supply supplying power is a predetermined power supply or not, and control processing that displays, when the determination processing determines that the power supply is the predetermined power supply, a power-on continuation confirmation screen and continues, in case of detection of a confirmation operation from the user according to the power-on continuation confirmation screen, lighting of the light source.
