Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If devices maintain standby power to receive commands from remote controllers, then device availability and responsiveness are improved, but power consumption increases and component lifespan decreases

Engineering Contradiction:

Improvedevice availabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary detection using photodiodes to sense incoming infrared or radio signals before fully activating the device. This preliminary action allows the device to remain in a low-power state until a command is actually detected, thereby maintaining availability while minimizing standby power consumption.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The device alternates between low-power standby states and active states in periodic cycles. During standby, photodiodes periodically detect for incoming signals, and when detected, the device transitions to active state to process commands. This periodic activation pattern reduces overall power consumption while maintaining device responsiveness.

Inventive Principle:

Principle #19Periodic action

2Speed

If devices maintain standby power to receive commands, then device responsiveness is improved, but component lifespan deteriorates

Engineering Contradiction:

Improveresponse timeVSAvoidcomponent lifespan

Core Design Contradiction:

SpeedVSDuration of action of stationary object

Solution Approach 1:

The photodiodes continuously monitor for incoming signals in a low-power state, performing preliminary detection before full device activation. This ensures rapid response to commands while minimizing the time components spend in high-power operational states, thereby extending component lifespan.

Inventive Principle:

Principle #10Preliminary action

3Use of energy by moving object

If devices transition to low-power states, then power consumption is reduced, but device complexity increases due to automated transitioning mechanisms

Engineering Contradiction:

Improvepower consumptionVSAvoidpower management complexity

Core Design Contradiction:

Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The system uses photodiodes to automatically detect incoming signals and trigger transitions between power states without requiring external control or complex management systems. The photodiodes themselves initiate the wake-up process by detecting infrared or radio signals, making the power management self-regulating and reducing overall system complexity.

Inventive Principle:

Principle #25Self-service

4Reliability

If photodiodes continuously detect signals, then device availability is maintained, but power consumption increases

Engineering Contradiction:

Improvedevice availabilityVSAvoidstandby power loss

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The photodiodes operate in periodic detection cycles during standby, alternating between active detection and low-power states. This periodic operation maintains device availability by detecting incoming signals when they occur while minimizing energy loss during extended standby periods through reduced detection activity.

Inventive Principle:

Principle #19Periodic action
