Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Bicycle head units struggle to adapt to different bicycle configurations and user profiles when used across multiple bicycles, requiring manual reactivation and reconfiguration.

Innovation Solution

A controller device with multiple communication interfaces and a processor that identifies bicycles based on component data and auxiliary data, such as location, to automatically configure settings and display user profiles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a bicycle head unit is used across multiple bicycles with different configurations, then the head unit can serve multiple bicycles, but manual reactivation and reconfiguration is required for each bicycle

Engineering Contradiction:

Improvehead unit compatibility across multiple bicyclesVSAvoidsetup time per bicycle

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The head unit automatically identifies the bicycle by comparing component data (serial numbers, component identifiers) from connected bicycle components against stored profiles, and automatically loads the appropriate configuration without user intervention. The system self-configures display settings, sensor activations, and data collection parameters based on the identified bicycle profile.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Bicycle configurations and user profiles are pre-stored in the head unit's memory before the bicycle is used. When a bicycle is connected, the head unit retrieves the pre-stored profile matching the detected component data, eliminating the need for real-time configuration during setup.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If a bicycle head unit is used across multiple bicycles with different configurations, then the head unit can serve multiple bicycles, but manual reconfiguration is required for each bicycle

Engineering Contradiction:

Improvehead unit compatibility across multiple bicyclesVSAvoidconfiguration simplicity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The head unit stores complete configuration profiles (including display settings, sensor configurations, and data collection parameters) for each bicycle in its memory. When a bicycle is identified, the system copies the appropriate pre-stored profile into active operation, replacing the need for manual reconfiguration.

Inventive Principle:

Principle #26Copying

3Measurement precision

If component data from multiple bicycles is stored for identification, then accurate bicycle recognition is achieved, but memory requirements increase

Engineering Contradiction:

Improvebicycle identification accuracyVSAvoidstored data volume

Core Design Contradiction:

Measurement precisionVSQuantity of substance

Solution Approach 1:

The bicycle identification system divides the configuration data into discrete component profiles (e.g., crankset, rear derailleur, shifters, display unit) with unique identifiers. Each component has its own data segment stored in the head unit, allowing precise identification through component serial numbers while keeping individual data units compact and manageable.

Inventive Principle:

Principle #1Segmentation

AI summary

A controller device usable with a bicycle includes a communication interface configured to receive component data from another controller device of the bicycle. The communication interface is configured to receive auxiliary data from outside the bicycle. The controller device includes a processor in communication with the communication interface. The processor being is configured to determine a location of the bicycle based on the auxiliary data, compare the received component data to a plurality of predetermined component datasets for a plurality of bicycles, respectively, and identify at least one bicycle of the plurality of bicycles based on the comparison and the determined location of the bicycle. The at least one bicycle includes the bicycle. The controller device includes a display in communication with the processor. The display is configured to display a representation for each bicycle of the at least one identified bicycle.
