Solution Overview

Problem

Existing electric motorcycles face challenges with complex and time-consuming battery removal and replacement processes, which limit their operational time and efficiency, especially in sports competitions.

Innovation Solution

The design of an electric motorcycle with a frame that serves as both a structural skeleton and a support for battery casings, allowing for lateral removal and replacement of batteries through a system of structural elements and engagement means, simplifying the process and reducing downtime.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If batteries are positioned in a single casing inside the motorcycle for compactness, then space utilization is improved, but battery removal becomes complex and time-consuming

Engineering Contradiction:
Improvespace utilizationVSAvoidbattery removal time
Core Design Contradiction:
Volume of moving objectVSLoss of time

Solution Approach 1:

The patent divides the battery system into separate individual battery units instead of a single integrated casing. Each battery can be independently removed from the motorcycle, allowing operators to quickly exchange batteries without complex disassembly operations. This segmentation resolves the contradiction by maintaining compact space utilization while enabling rapid battery replacement.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If batteries are made integral to the vehicle structure for stability, then structural integrity is improved, but battery replacement requires complete vehicle dismantling

Engineering Contradiction:
Improvestructural integrityVSAvoidbattery replacement ease
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent extracts the batteries from the integral vehicle structure, positioning them in accessible locations within the motorcycle body rather than permanently integrating them into the frame. This allows batteries to be removed and replaced independently without dismantling the vehicle's structural components, thus maintaining structural integrity while greatly improving battery replacement ease.

Inventive Principle:
Principle #2Taking out (Extraction)

3Duration of action of moving object

If multiple batteries are used to extend operational time, then energy capacity is improved, but battery replacement complexity increases

Engineering Contradiction:
Improveoperational timeVSAvoidbattery replacement complexity
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The patent implements separate casings for each battery unit, allowing individual batteries to be independently accessed and replaced. When multiple batteries are used to extend operational time, operators can quickly swap out depleted batteries one by one without complex multi-battery replacement procedures, thus maintaining extended operational capability while reducing replacement complexity.

Inventive Principle:
Principle #1Segmentation
