Solution Overview

Problem

Existing smart self-balancing vehicles lack a unified and adaptive safety mechanism to accommodate varying rider experiences and proficiency levels, as they rely on fixed speed limits and user-defined settings, which do not dynamically adjust to individual rider performance.

Innovation Solution

A method and device that determine a user level based on riding data such as time, distance, shaking frequency, and shaking arc magnitude, allowing for real-time adjustment of startup acceleration to ensure safe riding by limiting or unlocking speed according to the user's proficiency level.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If fixed speed limits are implemented for safety, then safety is improved, but adaptability to different rider skill levels deteriorates

Engineering Contradiction:
ImprovesafetyVSAvoidadaptability to rider skill levels
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic speed limits that automatically adjust based on real-time riding data analysis. The system transitions from static, fixed speed limits to dynamic, adaptive speed limits that change according to the rider's demonstrated skill level, thereby resolving the contradiction between safety and adaptability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system continuously collects riding data (shaking frequency, arc magnitude, riding time) and uses this feedback to automatically evaluate and adjust the rider's skill level. This closed-loop feedback mechanism enables the speed limit to adapt to the rider's improving skills, maintaining safety while increasing adaptability.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If user-defined settings are used, then adaptability is improved, but ease of operation deteriorates

Engineering Contradiction:
ImproveadaptabilityVSAvoidease of operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system performs automatic skill level evaluation and speed limit adjustment without requiring user intervention. The rider simply operates the vehicle normally while the system autonomously collects data, evaluates performance, and configures appropriate speed limits, eliminating the need for manual settings while maintaining adaptability.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system proactively evaluates riding data and adjusts speed limits before safety issues arise. By continuously monitoring and preemptively adapting the speed limit based on skill level, the system eliminates the need for users to manually configure settings, thereby improving ease of operation while maintaining adaptability.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If startup acceleration is limited for safety, then safety is improved, but productivity deteriorates

Engineering Contradiction:
ImprovesafetyVSAvoidstartup acceleration performance
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent implements dynamic startup acceleration limits that adjust based on the rider's skill level. Beginner riders experience limited startup acceleration for safety, while experienced riders automatically gain higher acceleration performance through automatic skill-based adjustment, resolving the contradiction between safety and productivity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the startup acceleration parameter dynamically based on evaluated skill level. By adjusting this critical performance parameter according to rider competency, the system maintains safety for beginners while enabling high performance for experienced riders, eliminating the trade-off between safety and productivity.

Inventive Principle:
Principle #35Parameter changes
