Solution Overview

Problem

Existing systems face inefficiencies in electric power supply from vehicles due to varying capacities, leading to vehicles running out of power during supply, necessitating frequent vehicle replacements, which disrupts effective power delivery to facilities.

Innovation Solution

A server acquires and processes electric power supply information from multiple vehicles, sets energy distribution based on vehicle capabilities, and controls power supply and distribution to ensure efficient and continuous power delivery to facilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If multiple vehicles with different electric power supply capacities are used to supply power to a facility, then the total power supply capacity is increased, but some vehicles may run out of power during supply operations, requiring frequent vehicle replacements which disrupts continuous power delivery

Engineering Contradiction:
Improvetotal power supply capacityVSAvoidcontinuous power supply stability
Core Design Contradiction:
PowerVSReliability

Solution Approach 1:

The server performs preliminary acquisition of electric power supply information from each vehicle before the power supply operation begins. By knowing in advance the power supply capacity of each vehicle, the server can pre-calculate and determine the optimal energy distribution plan for each vehicle, ensuring that power supply tasks are allocated in a way that prevents vehicles from running out of power during operations, thereby eliminating the need for frequent vehicle replacements and ensuring continuous power delivery to the facility.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts the energy distribution for each vehicle based on its specific power supply capacity. The server sets the electric energy to be supplied by each vehicle according to its capabilities, creating a dynamic allocation strategy that adapts to the heterogeneous characteristics of different vehicles. This dynamic approach ensures that each vehicle operates within its capacity limits throughout the power supply task, maintaining system reliability.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If electric energy is uniformly distributed to all vehicles, then the control system is simplified, but vehicles with different power supply capacities cannot efficiently contribute to the facility's power needs, leading to suboptimal power supply efficiency

Engineering Contradiction:
Improvecontrol system complexityVSAvoidpower supply efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The server implements local quality by setting the electric energy to be supplied by each vehicle according to its specific power supply capacity characteristics. Instead of applying a uniform energy distribution policy to all vehicles, the system tailors the energy allocation to match each vehicle's capabilities. This localized approach ensures that vehicles with higher capacity contribute more energy, while vehicles with lower capacity contribute appropriately less, thereby optimizing the overall power supply efficiency without requiring overly complex control mechanisms.

Inventive Principle:
Principle #3Local quality

3Duration of action of moving object

If vehicles are frequently replaced when they run out of power, then the power supply can be maintained, but the operation efficiency is reduced due to repeated connection and disconnection operations

Engineering Contradiction:
Improvepower supply durationVSAvoidoperation efficiency
Core Design Contradiction:
Duration of action of moving objectVSProductivity

Solution Approach 1:

The server performs preliminary acquisition of electric power supply information from each vehicle before the power supply operation begins. By knowing in advance the power supply capacity of each vehicle, the server can pre-calculate and determine the optimal energy distribution plan for each vehicle, ensuring that power supply tasks are allocated in a way that prevents vehicles from running out of power during operations, thereby eliminating the need for frequent vehicle replacements and ensuring continuous power delivery to the facility.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system ensures continuous power supply to the facility by optimizing the energy distribution among vehicles based on their capabilities. The server determines the electric energy to be supplied by each vehicle in advance, which ensures that the power supply operation can proceed continuously without interruption from vehicle replacements. This continuity of useful action maintains both the duration of power supply and the operational efficiency of the system.

Inventive Principle:
Principle #20Continuity of useful action
