Solution Overview

Problem

Existing aerosol-generating devices waste power when displaying simple information on detailed display units and may fail to provide detailed information due to the cover concealing the simple display unit.

Innovation Solution

An electronic device with a main body having a simple display unit and a cover with a detailed display unit that does not conceal the simple unit, controlled to display simple information on the simple unit and detailed information on the detailed unit, with the detailed unit positioned either non-transparent or transparent relative to the simple unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If simple information is displayed on the detailed display unit, then detailed information can be provided, but power is wasted

Engineering Contradiction:
Improveinformation detail levelVSAvoidpower consumption
Core Design Contradiction:
Loss of informationVSLoss of energy

Solution Approach 1:

The display function is segmented between two display units: a simple display unit on the main body for basic information display, and a detailed display unit on the cover for comprehensive information. This segmentation allows the system to use the appropriate display unit for appropriate information levels, avoiding power waste on unnecessary detailed display while ensuring detailed information is available when needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically selects which display unit to activate based on the information type and user needs. The control unit determines whether to display simple or detailed information, and accordingly activates either the simple display unit, the detailed display unit, or both simultaneously. This dynamic adaptation optimizes power consumption by avoiding continuous operation of the power-intensive detailed display unit.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the cover conceals the simple display unit, then protection is achieved, but detailed information display is prevented

Engineering Contradiction:
Improveprotection levelVSAvoidinformation accessibility
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The solution moves from a single-display configuration to a dual-display configuration across different spatial dimensions. The simple display unit remains on the main body while the detailed display unit is added on the cover, allowing both displays to operate simultaneously without occlusion. This dimensional expansion resolves the contradiction by providing protection through the cover while maintaining information accessibility through the additional display layer.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The system merges the simple display unit and detailed display unit into a coordinated dual-display system. The control unit integrates both display units to work together, with the detailed display unit supplementing the simple display unit rather than replacing it. This merging allows the cover to provide protection while the combined display system ensures comprehensive information is always accessible.

Inventive Principle:
Principle #5Merging (Combining)

3Loss of energy

If the simple display unit is used alone, then power consumption is reduced, but detailed information cannot be displayed

Engineering Contradiction:
Improvepower consumptionVSAvoidinformation detail level
Core Design Contradiction:
Loss of energyVSLoss of information

Solution Approach 1:

The system dynamically adapts its display configuration based on information requirements. When detailed information is needed, the control unit activates both the simple display unit and the detailed display unit. When only basic information is required, the system can rely on the simple display unit alone, optimizing power consumption. This dynamic control strategy resolves the contradiction by matching display complexity to information needs.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The simple display unit serves multiple functions: it can display simple information alone to conserve power, or it can work in conjunction with the detailed display unit to provide comprehensive information. This multi-functionality allows the system to maintain low power consumption while ensuring detailed information is available when needed, as the simple display unit remains operational regardless of the detailed display unit's state.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Provided is an electronic device comprising a body which includes a simple display unit which executes simple display, a cover which includes a detailed display unit for executing detailed display and does not hide the simple display unit even when the cover is mounted to the body, and a control unit which executes such control that simple information is displayed on the simple display unit and detailed information obtained by detailing the simple information is displayed on the detailed display unit.
