Solution Overview

Problem

Electric scooters face challenges with limited battery endurance, lack of real-time battery state monitoring, and inefficient lease management, leading to poor user experience and high maintenance requirements.

Innovation Solution

An electric power motion apparatus equipped with a battery pack, power unit, lease control unit, and auxiliary steering unit, which includes a control CPU, GPS-based positioning module, and communication module to monitor and adjust the scooter's location and battery state in real-time, ensuring it returns to the lease station when power is low or when outside the designated range.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If a large-capacity rechargeable battery is used to ensure normal operation, then the power supply capability is improved, but the weight and volume of the scooter increase

Engineering Contradiction:
Improvepower supply capabilityVSAvoidscooter weight
Core Design Contradiction:
Use of energy by moving objectVSWeight of moving object

Solution Approach 1:

The battery system is segmented into a main battery pack and a portable power bank. The main battery provides primary power for normal operation, while the power bank serves as a supplementary energy source that can be detached and carried separately. This segmentation allows the scooter to maintain adequate power supply capability without requiring a single large battery that would increase weight and volume excessively.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The power supply solution transitions from a single-dimension approach (one large battery) to a multi-dimension approach by adding a portable power bank that can be used in conjunction with the main battery. The power bank can be carried by the user separately, effectively adding a portable energy dimension that supplements the fixed battery system, thereby providing adequate power supply without increasing the scooter's weight and volume.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If no real-time monitoring system is installed, then the device complexity is reduced, but the lease management efficiency deteriorates

Engineering Contradiction:
Improvelease management efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The scooter is equipped with a monitoring system that continuously tracks battery state (remaining power and charge/discharge cycles) and location information. This feedback mechanism provides real-time data to the lease management system, enabling efficient management decisions. The system automatically monitors whether the scooter is within the lease range and whether the battery requires recharging or replacement, thereby improving lease management efficiency without requiring overly complex manual intervention systems.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The monitoring system enables a degree of self-service in lease management by automatically tracking and reporting battery status and location. The system can independently determine when a battery needs recharging or replacement and whether the scooter has exceeded its lease range, reducing the need for manual checking and management interventions while improving overall management efficiency.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the scooter operates without autonomous return capability, then the ease of operation is improved, but the user experience deteriorates when power is insufficient

Engineering Contradiction:
Improvecontrol simplicityVSAvoidreturn to lease station reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary assessment of battery status and location before the scooter becomes unable to return to the lease station. By monitoring remaining power and charge/discharge cycles in advance, the system can predict when the scooter will be unable to complete its return journey and take preventive measures, such as alerting the user or automatically initiating return procedures while the scooter still has sufficient power, thereby ensuring reliable return without compromising operational simplicity.

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The monitoring system performs preliminary actions by continuously tracking battery state and location information before the scooter encounters power insufficiency. This allows the system to prepare for potential return issues in advance, such as notifying users of low battery status or automatically planning return routes while power is still available, ensuring that the scooter can reliably return to the lease station without requiring complex autonomous navigation capabilities.

Inventive Principle:
Principle #10Preliminary action

4Reliability

If extensive manual maintenance is implemented, then the reliability of scooter operation is improved, but the productivity of lease management deteriorates

Engineering Contradiction:
Improvescooter operation reliabilityVSAvoidlease management efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The monitoring system provides continuous feedback on battery health indicators including remaining power and charge/discharge cycle count. This automated feedback mechanism enables the system to track battery degradation and predict maintenance needs, reducing reliance on extensive manual maintenance while ensuring scooter operation reliability. The system can automatically identify when batteries require maintenance or replacement based on monitored parameters.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The scooter and monitoring system perform self-service by automatically tracking their own operational status and maintenance needs. The system independently monitors battery health, tracks usage patterns, and identifies when maintenance is required, reducing the need for manual inspection and maintenance interventions. This self-monitoring capability maintains scooter reliability while improving lease management productivity by eliminating the need for extensive manual maintenance activities.

Inventive Principle:
Principle #25Self-service

AI summary

A lease management method of an electric power motion apparatus includes acquiring location information, an advancement direction and a battery state of the electric power motion apparatus; additionally adjusting the advancement direction of the electric power motion apparatus to face towards the lease station such that the electric power motion apparatus faces towards the lease station based on normal adjustment and control if the electric power motion apparatus is located outside a lease range of a lease station; and additionally controlling the electric power motion apparatus to decelerate, and additionally adjusting the advancement direction of the electric power motion apparatus to face towards the lease station such that the electric power motion apparatus advances towards the lease station based on normal adjustment and control if a remaining power amount of the electric power motion apparatus approaches a power amount for returning to the lease station.
