Solution Overview

Problem

Commercial advertising machines consume excessive power in standby mode due to advanced processor functions and high integration levels, leading to increased power wastage and reduced lifespan.

Innovation Solution

A system comprising a standby control unit, an application processing unit, and a power source unit that controls the advertising machine's operation by stopping power to the application processing unit during standby periods and resuming power when the machine is set to operate, using a predefined standby scheme.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If the application processing unit maintains continuous operation to enable automatic wake-up, then the advertising machine can automatically start at the beginning of the operating period, but the standby power consumption increases significantly

Engineering Contradiction:

Improveautomatic wake-up capabilityVSAvoidstandby power consumption

Core Design Contradiction:

Extent of automationVSUse of energy by moving object

Solution Approach 1:

The control system is segmented into two independent parts: a low-power standby control unit that remains active during standby mode, and a high-performance application processing unit that is powered down during standby. This segmentation allows the machine to wake up automatically through the standby control unit while keeping the power-intensive application processing unit off, thus resolving the contradiction between automation and power consumption.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system implements periodic power cycling of the application processing unit, switching between standby mode (powered off) and operating mode (powered on) based on predetermined schedules. This periodic action enables automatic wake-up at scheduled times while minimizing power consumption during standby periods.

Inventive Principle:

Principle #19Periodic action

2Adaptability or versatility

If the application processing unit operates at high frequency and integration level to improve machine functions, then the advertising machine gains advanced capabilities, but the standby power consumption increases and lifespan decreases

Engineering Contradiction:

Improvemachine functionsVSAvoidpower wastage

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The system dynamically adjusts the operational state of the application processing unit based on the current mode (standby or operating). During standby, the unit is completely powered down to eliminate power wastage. During operation, it operates at high frequency and integration level to provide advanced capabilities. This dynamic state adjustment resolves the contradiction between versatility and energy loss.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The power consumption parameters of the application processing unit are changed based on operational requirements. By switching the power supply state (on/off) and adjusting frequency levels dynamically, the system achieves high performance when needed while minimizing power wastage during standby, thus extending the overall lifespan of the machine.

Inventive Principle:

Principle #35Parameter changes

3Speed

If the application processing unit remains active during standby mode, then the advertising machine can respond quickly to start operations, but the power consumption during standby period increases

Engineering Contradiction:

Improvestartup response speedVSAvoidstandby period power consumption

Core Design Contradiction:

SpeedVSUse of energy by stationary object

Solution Approach 1:

The standby control unit performs preliminary actions during standby mode by maintaining essential timing and control functions with minimal power consumption. When wake-up time arrives, it triggers the application processing unit to start up. This preliminary preparation enables fast response without requiring the full application processing unit to remain active, thus reducing standby power consumption while maintaining quick startup capability.
