Solution Overview

Problem

Electronic devices may not operate at maximum power settings when using non-standard or third-party power sources, as these sources often fail to communicate their power supply capability information, leading to potential underperformance or failure due to incorrect power usage.

Innovation Solution

A power adapter with multiple inputs and outputs that receives and manages power supply capability information from an external source, allowing it to operate electronic devices at maximum power settings even with non-standard power sources, and provides redundancy and voltage regulation to prevent power supply failures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If non-standard or third-party power sources are used, then device versatility and adaptability are improved, but power supply capability information is lost leading to incorrect power usage

Engineering Contradiction:
Improvepower source compatibilityVSAvoidpower supply capability information
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The power adapter serves as an intermediary device between the non-standard power source and the electronic device. It receives power supply capability information from the power source through its first input interface and communicates this information to the electronic device through its second input interface, thereby mediating the information loss and enabling correct power usage with versatile power sources.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If power supply capability information is not communicated, then device simplicity is maintained, but electronic devices operate at lowest power setting or fail to operate

Engineering Contradiction:
Improvepower adapter complexityVSAvoiddevice power output
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The power adapter performs preliminary action by receiving and processing power supply capability information from the power source before delivering power to the electronic device. This preliminary information gathering and processing enables the adapter to configure correct power delivery parameters, ensuring the device operates at maximum power setting rather than lowest setting or failing to operate.

Inventive Principle:
Principle #10Preliminary action

3Use of energy by moving object

If power supply capability information is communicated from external source, then maximum power efficiency is achieved, but system complexity increases

Engineering Contradiction:
Improvepower efficiencyVSAvoidpower management system complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The power adapter is designed with multi-functionality, serving multiple purposes: it acts as a power source interface, an information communication device, and a power management system. By consolidating these functions into a single adapter unit, the system achieves maximum power efficiency through external information communication while minimizing the increase in overall system complexity.

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

4Reliability

If power management and redundancy are implemented, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improvepower supply reliabilityVSAvoidpower adapter complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The power adapter implements redundancy by providing multiple input interfaces that can receive power from different power sources. This beforehand cushioning ensures that if one power source fails or provides incorrect information, alternative power sources can compensate, thereby improving reliability without requiring overly complex power management systems.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
