Solution Overview

Problem

Power wastage occurs when a cover is attached to an electronic device with a simple display unit, regardless of the type of cover, leading to unnecessary display activation.

Innovation Solution

An electronic device with a control unit that determines whether to activate the simple display unit based on the type of cover attached, ensuring display is provided only when necessary.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the simple display unit is always activated, then the display function is always available, but power is wasted when a cover is attached

Engineering Contradiction:

Improvedisplay availabilityVSAvoidpower wastage

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The display unit dynamically changes its operational state based on cover attachment detection. The control unit switches the display between active and inactive states depending on whether a cover is detected, allowing the system to adapt its power consumption to actual usage conditions rather than maintaining a fixed state

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system automatically detects cover attachment and autonomously decides whether to activate or deactivate the display unit without requiring user intervention. The control unit monitors the cover state and self-regulates display operation accordingly

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If the display is provided when any cover is attached, then the display function remains useful, but power is wasted on covers with detailed display units

Engineering Contradiction:

Improvedisplay compatibilityVSAvoidunnecessary power consumption

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The system applies different display control strategies based on the specific type of cover attached. When a cover with a detailed display unit is detected, the simple display unit is deactivated. When a cover without detailed display is attached, the simple display unit remains active, creating localized quality adjustments based on cover characteristics

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The control unit changes the operational parameters of the display unit based on cover type detection. By identifying whether the attached cover has a detailed display unit, the system adjusts the display activation state to optimize power consumption while maintaining appropriate display functionality

Inventive Principle:

Principle #35Parameter changes

AI summary

An electronic device comprising a simple display unit that performs simple display and a control unit that performs control such that display by the simple display unit is performed when a cover is not attached, wherein when a cover is attached, the control unit determines, in accordance with the cover type, whether or not display is to be performed by the simple display unit.
