Solution Overview

Problem

Existing assemblies of carrier rolling motor vehicles and boardable electric vehicles face challenges in maintaining the reliability and efficiency of electricity supply, particularly when the carrier vehicle is idle for extended periods, leading to potential breakdowns due to insufficient recharging capabilities.

Innovation Solution

An autonomous electricity production generator, independent of the carrier vehicle, is integrated into the assembly, allowing for continuous electricity production even when the carrier vehicle is stopped, coupled with an energy management system that stores and distributes energy efficiently, preventing wheel rotation and ensuring reliable recharging of the boardable vehicle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the carrier vehicle is used as a power supply source for the on-board electric vehicle, then the on-board vehicle can be recharged during transport, but the operating periods of the carrier vehicle must be long enough which creates risk of breakdowns when the carrier vehicle is idle

Engineering Contradiction:

Improvereliability of electricity supplyVSAvoidoperating periods of carrier vehicle

Core Design Contradiction:

ReliabilityVSDuration of action of moving object

Solution Approach 1:

The power supply system is segmented into two independent components: the carrier vehicle's power system and the on-board vehicle's autonomous generator. The autonomous generator is mounted on the on-board vehicle itself, separating the power generation function from the carrier vehicle, thereby ensuring continuous power supply regardless of the carrier vehicle's operating status.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The on-board vehicle is equipped with its own autonomous generator that can produce electricity independently without relying on the carrier vehicle. This self-service capability allows the on-board vehicle to recharge its batteries at any time, eliminating the dependency on the carrier vehicle's operating periods and preventing breakdowns during idle times.

Inventive Principle:

Principle #25Self-service

2Reliability

If the on-board vehicle is recharged continuously during transport, then battery reliability is maintained, but the electrical connection may be damaged by wheel rotation during vehicle movement

Engineering Contradiction:

Improvebattery charge reliabilityVSAvoiddamage to electrical connection

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The management system proactively monitors the operational state of both vehicles and anticipates potential damage to the electrical connection. When the carrier vehicle is in motion or the on-board vehicle's wheels are rotating, the management system preemptively disconnects the electrical connection or prevents recharging, thereby avoiding damage before it occurs.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The management system continuously receives feedback from sensors monitoring the operational status of both vehicles, including wheel rotation detection. Based on this real-time feedback, the system dynamically controls the electrical connection state, enabling recharging only when safe conditions are detected and preventing connection damage by disconnecting when motion is detected.

Inventive Principle:

Principle #23Feedback
