Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If Level 3 DC fast charging stations are deployed to enable widespread EV adoption, then charging speed is improved, but power distribution network infrastructure must be extensively overhauled

Engineering Contradiction:

Improvecharging speedVSAvoidpower distribution network infrastructure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system segments the power distribution function by deploying distributed battery energy storage systems at charging stations rather than relying on centralized grid infrastructure. Each charging station becomes an independent energy node with local storage capacity, eliminating the need for extensive grid overhaul while maintaining fast charging capability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Battery energy storage systems serve as intermediary devices between the utility grid and EV charging outlets. The storage systems buffer and regulate power flow, enabling fast charging without requiring the utility grid to directly supply high peak powers. This intermediary layer decouples the charging speed from grid infrastructure requirements.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Power

If Level 3 DC fast charging stations draw massive peak power from the utility grid, then charging capacity is improved, but energy losses and carbon footprint increase

Engineering Contradiction:

Improvepeak power capacityVSAvoidenergy losses

Core Design Contradiction:

PowerVSLoss of energy

Solution Approach 1:

Battery energy storage systems pre-store electrical energy during periods of low demand or renewable generation. By charging the storage systems in advance and discharging during peak charging periods, the system eliminates the need for real-time high-power grid draws, reducing transmission losses and enabling fast charging from locally stored energy.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system changes the temporal parameter of power delivery by decoupling energy storage from immediate consumption. Energy is stored when available and delivered when needed, transforming the power delivery profile from peak-intensive to balanced, thereby reducing energy losses while maintaining charging capacity.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If Level 3 DC fast charging infrastructure is deployed to match gas station density, then EV adoption is improved, but capital expenditures and demand charges increase

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Battery energy storage systems enable charging stations to serve themselves by storing energy locally and providing power during peak demand periods without incurring high demand charges from the utility grid. The storage systems act as self-contained energy reservoirs, eliminating the need for expensive grid infrastructure upgrades and reducing operational costs.

Inventive Principle:
