Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single fixed acceleration profile is used in conventional E-Bikes, then the system is simple to operate, but it cannot accommodate diverse user preferences and environments

Engineering Contradiction:

Improveadaptability to diverse user preferences and environmentsVSAvoidcomplexity of acceleration profile customization

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic acceleration profiles that can be automatically adjusted based on real-time detection of user characteristics (age, skill level) and environmental conditions. The system transitions from static fixed profiles to dynamic adaptive profiles that evolve based on detected parameters, resolving the contradiction between adaptability and complexity through automated adjustment mechanisms.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters (acceleration rates, power assist levels) based on detected user and environmental parameters. By modifying acceleration profile parameters dynamically rather than requiring manual reconfiguration, the system achieves high adaptability while maintaining operational simplicity.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If multiple fixed acceleration profiles are provided, then user customization is enabled, but the system becomes more complex

Engineering Contradiction:

Improvecustomization capabilityVSAvoidease of profile selection and adjustment

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system performs self-service by automatically detecting user characteristics and environmental conditions to select and adjust acceleration profiles without manual user input. The detection system autonomously gathers data from sensors and processing units, eliminating the need for users to manually navigate complex profile selection interfaces.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system incorporates feedback loops where detected user and environmental parameters continuously inform acceleration profile adjustments. This closed-loop feedback mechanism enables automatic adaptation while keeping the user interface simple, as the system learns from real-time data rather than requiring explicit user configuration.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If acceleration profiles are manually configured, then user control is maximized, but the system requires more user input and processing

Engineering Contradiction:

Improvetailoring to individual user needsVSAvoidtime for profile configuration

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs preliminary detection and configuration actions by automatically identifying user characteristics and environmental conditions before acceleration profile selection is needed. This advance preparation eliminates the need for users to spend time manually configuring profiles, as the system pre-determines appropriate settings based on detected parameters.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces manual mechanical configuration with automated electronic detection and processing. Instead of requiring users to manually adjust settings through interfaces, the system uses sensors and processing units to automatically determine and apply optimal acceleration profiles, substituting manual operations with automated electronic systems.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A control system for a power assist propulsion system and a user-rideable vehicle. The control system includes memory storing a one or more acceleration profiles. The system also includes a processor communicatively coupled to the memory and to a motorized propulsion subsystem configured to propel the vehicle in concert with, or independently of, a manual propulsion subsystem. The processor controls the motorized propulsion subsystem based on one or the acceleration profiles from the set of acceleration profiles. A communications interface communicatively coupled to the processor share one or more acceleration profiles with a second control system of a second user-rideable vehicle based on input received from a user.
