Vehicle Task Control for Dynamic Mode Switching Under Demand Changes

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing vehicle management systems fail to flexibly adjust vehicle usage time when unexpected increases in product or article delivery demands occur, limiting usability.

Innovation Solution

A task management device that includes a control unit to detect specific conditions during a vehicle's operation in a first mode and initiate a mode switch to a second mode before the scheduled end time, allowing for flexible vehicle usage time adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If vehicle usage schedule is fixed in advance, then schedule management is simple and reliable, but flexibility to respond to unexpected demand changes is poor

Engineering Contradiction:

Improveflexibility of vehicle usage timeVSAvoidcomplexity of schedule management system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic schedule adjustment by enabling real-time modification of vehicle usage periods based on detected demand conditions. The control unit monitors product delivery demands and automatically adjusts the vehicle's operational schedule, transitioning from static pre-defined periods to dynamic adaptable periods that respond to actual business needs.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system incorporates feedback mechanisms where the control unit continuously monitors delivery demand conditions and uses this information to adjust vehicle usage schedules. When unexpected increases in delivery demands are detected, the system feeds this information back to modify the operational period, enabling adaptive response to changing conditions.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If vehicle mode switching is scheduled in advance, then operational planning is simple, but responsiveness to unexpected delivery demands is insufficient

Engineering Contradiction:

Improveresponsiveness to delivery demandVSAvoidease of schedule adjustment

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system implements self-service automation where the control unit automatically detects delivery demand conditions and executes vehicle mode switching without requiring manual intervention. When the monitoring unit detects unexpected increases in delivery demands, the control unit autonomously determines the appropriate vehicle mode and initiates the switching process, reducing operational complexity.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent employs preliminary action by pre-configuring multiple vehicle modes and their corresponding operational parameters. When delivery demands change, the system can quickly switch between pre-prepared modes rather than configuring new operational settings from scratch, enabling rapid response to demand fluctuations.

Inventive Principle:

Principle #10Preliminary action

AI summary

A task management device includes a control unit that executes, when satisfaction of a specific condition is detected during a period in which a vehicle to be operated in a mode corresponding to an application is operated in a first mode, operation start control to start an operation of the vehicle in a second mode that is different from the first mode before a schedule end time of the period.
