Solution Overview

Problem

Existing remotely operated vehicle systems for picking up storage bins from storage systems experience operational downtime due to the need for battery recharging, limiting the overall operational cycle to approximately 16 hours per day.

Innovation Solution

A remotely operated vehicle assembly with a vehicle body, lifting device, and driving means, equipped with both main and auxiliary power sources, allowing for automatic power transfer between charging stations without human intervention, enabling continuous operation through wireless communication and a management system that monitors and controls power sources, including batteries and capacitors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If the vehicle uses a rechargeable battery to supply electrical power to the motor, then the vehicle can operate autonomously, but the operational cycle is limited to approximately 16 hours per day due to recharging needs

Engineering Contradiction:
Improveoperational cycleVSAvoidrecharging downtime
Core Design Contradiction:
Duration of action of moving objectVSLoss of time

Solution Approach 1:

The power source is divided into multiple separate battery units that can be independently exchanged. When one battery is depleted, the vehicle can quickly swap to another charged battery, eliminating the need for prolonged recharging stops and extending the operational cycle beyond 16 hours per day.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system changes the power supply parameter from a single rechargeable battery to multiple interchangeable battery units. This parameter change allows continuous operation by swapping depleted batteries with charged ones, effectively removing the operational time limitation imposed by recharging requirements.

Inventive Principle:
Principle #35Parameter changes

2Duration of action of moving object

If the vehicle uses a single main power source, then the system structure is simple, but the vehicle cannot operate continuously for 24 hours per day

Engineering Contradiction:
Improveoperational cycleVSAvoidpower source system
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The power source system is segmented into multiple independent battery units rather than using a single large battery. This segmentation enables continuous operation through battery swapping while keeping each individual battery unit simple and manageable, thus extending operational duration without proportionally increasing system complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The vehicle's power system is designed to accept multiple interchangeable battery units that can be used in any sequence. This multi-functionality allows the same vehicle platform to operate continuously by simply changing which battery unit is active, achieving 24-hour operation capability without fundamentally redesigning the entire power system.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If the vehicle performs manual battery recharging, then the process is simple to implement, but it requires human intervention and causes operational standstill

Engineering Contradiction:
Improvepower source replacementVSAvoidoperational efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The vehicle is equipped with automatic coupling means that enable it to autonomously connect to charging stations and exchange battery units without human intervention. The coupling means automatically aligns and connects the battery units, allowing the vehicle to service itself and maintain continuous operation, thereby eliminating operational standstill caused by manual recharging.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manual mechanical process of battery replacement is replaced with an automated coupling system. The automatic coupling means uses mechanical guidance and automatic connection mechanisms to transfer battery units between the vehicle and charging stations, eliminating the need for manual handling while maintaining operational efficiency.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
