Solution Overview

Problem

The challenge lies in securing a reliable battery supply for electric vehicles with handlebars, as batteries require specific materials with limited availability, and integrating batteries into shared vehicles increases their value and maintenance costs, while also complicating their distribution and usage.

Innovation Solution

A method where the battery is transferred to a backpack worn by the user, which includes a network gateway for connecting to a portable terminal, allowing data processing and control of the electric vehicle, thereby reducing the need for integrated batteries and processing units in the vehicle, and enabling wireless data transmission using CAN data bus and wireless communication protocols.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If batteries are integrated into shared electric vehicles, then the vehicles have reliable power supply, but the value and maintenance costs increase

Engineering Contradiction:

Improvepower supply reliabilityVSAvoidmaintenance cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The battery is extracted from the shared electric vehicle and placed in a backpack worn by the user. This separates the valuable battery component from the shared vehicle, reducing the vehicle's value and maintenance costs while ensuring the user has reliable power supply through their personal backpack battery.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If batteries are integrated into shared electric vehicles, then the vehicles have reliable power supply, but the distribution and usage become complicated

Engineering Contradiction:

Improvepower supply reliabilityVSAvoiddistribution complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

By extracting the battery from the vehicle and placing it in the user's backpack, the system simplifies distribution. Users simply wear their backpack with the battery, and the vehicle becomes a simpler platform without integrated battery management, reducing operational complexity.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The backpack acts as an intermediary carrier between the user and the vehicle's power system. It contains the battery and interfaces with the vehicle through a connection device, simplifying the overall system architecture and distribution model.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Use of energy by moving object

If batteries use specific materials with limited availability, then the power supply performance is optimized, but the supply security deteriorates

Engineering Contradiction:

Improvepower supply performanceVSAvoidsupply security

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

Users take responsibility for their own battery supply by carrying it in their backpacks. This decentralized approach allows users to manage their own power supply needs, reducing dependence on centralized battery production and distribution chains that are constrained by material availability.

Inventive Principle:

Principle #25Self-service

AI summary

Examples of implementations include methods for powering a handlebar-mounted electric vehicle from a battery housed in a backpack. These methods include input data transmission, battery control, and electric vehicle control. They also include wireless data transmission via a network gateway, located in the backpack, to a handheld terminal; and cable transmission of electricity from the battery to the electric vehicle, with battery control commands determined by interpreting the input data.
