Solution Overview

Problem

There is a need for vehicle control technology specific to eco-friendly home delivery vehicles, particularly for distinguishing loading and unloading situations and securing battery State Of Charge (SOC) efficiently, especially in low-speed or stopping conditions, and for charging unmanned delivery robots effectively.

Innovation Solution

A method and system that utilize sensors and barcode scanning to determine loading/unloading based on weight and location information, calculate required SOC, and control battery charging to ensure optimal battery levels for both the vehicle and delivery robots, using Vehicle-to-Load (V2L) technology.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If home delivery vehicles operate in low-speed or stopping conditions frequently, then delivery service coverage is improved, but battery energy consumption increases

Engineering Contradiction:

Improvedelivery service coverageVSAvoidbattery energy consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary SOC assessment before delivery operations begin. The controller calculates required SOC based on predicted delivery routes, parcel weights, and stopping patterns, then ensures the battery is charged to adequate levels before the vehicle enters delivery zones with frequent low-speed operation, preventing energy depletion during critical delivery periods

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors actual SOC levels during delivery operations and compares them against predicted consumption patterns. When deviations are detected or SOC thresholds are approached, the system provides feedback to trigger charging operations, enabling dynamic energy management that adapts to actual delivery conditions rather than relying solely on pre-calculated estimates

Inventive Principle:

Principle #23Feedback

2Productivity

If the vehicle carries more parcels for efficient delivery, then productivity is improved, but battery weight and energy consumption increase

Engineering Contradiction:

Improvedelivery efficiencyVSAvoidbattery energy consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The system segments the delivery route into multiple zones and divides parcel deliveries across different segments. By analyzing SOC levels at each segment boundary, the controller can determine optimal points to offload parcels and recharge, allowing the vehicle to maintain high productivity across the overall route while managing energy consumption through spatial segmentation of the delivery task

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system calculates the minimum necessary SOC required to complete upcoming delivery segments and charges the battery to that specific threshold rather than maintaining continuously high charge levels. This partial charging approach provides sufficient energy for productive delivery operations without the excessive energy weight of always maintaining full battery charge

Inventive Principle:

Principle #16Partial or excessive action

3Ease of operation

If the vehicle stops frequently for parcel delivery, then service quality is improved, but battery charging opportunities are reduced

Engineering Contradiction:

Improveservice qualityVSAvoidcharging time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system identifies upcoming delivery stops in advance using navigation and route information, then proactively manages battery charging before the vehicle enters service zones where frequent stopping would occur. By ensuring adequate SOC is secured beforehand, the vehicle can perform quality delivery services without needing to interrupt operations for charging during critical service periods

Inventive Principle:

Principle #10Preliminary action

4Adaptability or versatility

If the vehicle battery SOC is not adequately managed before entering delivery zones, then operational flexibility is maintained, but delivery service reliability decreases

Engineering Contradiction:

Improveoperational flexibilityVSAvoiddelivery service reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

Inventive Principle:

Principle #23Feedback
