Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If battery-powered portable power supplies are used, then pollution from fossil fuels is reduced, but the power supply must be recharged frequently causing downtime

Engineering Contradiction:

ImprovepollutionVSAvoiddowntime

Core Design Contradiction:

Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The system enables continuous power supply by allowing the portable power supply unit to be recharged while still powering electronic devices. The charging unit connects to the power supply unit's battery through a charging port, enabling simultaneous charging and power delivery, thus eliminating downtime and maintaining continuous useful action.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

A charging unit acts as an intermediary between the power supply unit and external power sources. This intermediary enables the battery to be recharged while the power supply unit continues to function, mediating between the need for power delivery and the need for recharging without causing interruption.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of energy

If the portable power supply is transported to a charging station for recharging, then the battery can be recharged, but the electronic devices must be disconnected causing downtime

Engineering Contradiction:

Improverecharging capabilityVSAvoiddowntime

Core Design Contradiction:

Loss of energyVSLoss of time

Solution Approach 1:

The system eliminates the need to disconnect electronic devices during recharging. The charging unit connects to the power supply unit while it remains connected to electronic devices, allowing continuous power delivery and simultaneous recharging, thus maintaining continuous useful action without interruption.

Inventive Principle:

Principle #20Continuity of useful action

3Reliability

If multiple portable power supplies are transported separately to charging stations, then each can be recharged, but traffic increases and waiting time extends

Engineering Contradiction:

Improvepower supply availabilityVSAvoidcharging efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system merges multiple power supply units into a single networked system. Multiple portable power supply units can be connected to a single charging unit simultaneously, combining their recharging needs into one operation. This eliminates the need for separate transportation and charging of each unit, improving productivity and reducing waiting time while maintaining reliable power supply availability.

Inventive Principle:

Principle #5Merging (Combining)

4Adaptability or versatility

If a single power station services multiple mobile power supplies, then resource utilization improves, but additional power supplies must wait in line

Engineering Contradiction:

Improvepower station capacityVSAvoidwaiting time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system segments the power supply function into independent portable power supply units, each with its own charging port. This segmentation allows multiple units to be connected to and charged by a single charging unit simultaneously rather than sequentially, eliminating waiting time while maintaining high adaptability and versatility of the power station capacity.

Inventive Principle:

Principle #1Segmentation
