Solution Overview

Problem

Smart magic cubes experience high power consumption during dormancy monitoring, requiring frequent battery replacement or charging, and users face poor experiences due to delayed recording of operations during wake-up times.

Innovation Solution

Incorporating an accelerometer to detect acceleration values along three axes, automatically waking up the smart magic cube when acceleration exceeds a preset threshold, allowing functional modules to enter a normal working mode, thereby reducing power consumption and improving user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If real-time monitoring is performed on IO ports during dormancy state to detect rotation, then the smart magic cube can wake up in time to record rotation states, but the power consumption during dormancy remains high

Engineering Contradiction:

Improvewake-up timelinessVSAvoidpower consumption during dormancy

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent replaces the mechanical/electrical IO port monitoring system with an accelerometer-based detection system. The accelerometer uses gravitational field detection to sense cube orientation changes, substituting the high-power IO monitoring mechanism with a lower-power physical sensing approach that achieves the same wake-up function.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The accelerometer acts as an intermediary component between the physical rotation event and the wake-up function. Instead of directly monitoring IO ports for rotation signals, the system uses the accelerometer to detect gravitational changes caused by rotation, then triggers the wake-up process, thereby reducing direct monitoring power consumption.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Duration of action of moving object

If the smart magic cube enters dormancy state to save power, then battery life is extended, but users experience waiting time during power-on operation

Engineering Contradiction:

Improvebattery service lifeVSAvoidwake-up waiting time

Core Design Contradiction:

Duration of action of moving objectVSLoss of time

Solution Approach 1:

The accelerometer continues to operate at low power during dormancy state, performing preliminary detection of rotation events. This preliminary action allows the system to be pre-alerted of user interaction, enabling faster transition to full operation and reducing the effective waiting time users experience.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses periodic sampling by the accelerometer during dormancy state to detect rotation events. This periodic detection mechanism allows the cube to remain in low-power mode while still being able to quickly respond to user actions, balancing battery conservation with responsive user experience.

Inventive Principle:

Principle #19Periodic action

3Productivity

If continuous monitoring of all functional modules is maintained, then rotation states can be recorded immediately, but power consumption increases significantly

Engineering Contradiction:

Improverotation recording responsivenessVSAvoidpower consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The system segments the functional modules into essential (accelerometer for detection) and non-essential (display, communication, processing) during dormancy state. Only the essential accelerometer module remains active at low power, while non-essential modules are powered down, achieving selective operation that maintains responsiveness while reducing overall power consumption.

Inventive Principle:

Principle #1Segmentation
