Bicycle Controller Identification via Device Type Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle control systems limit the ability to uniquely identify and configure multiple identical controller devices, leading to confusion during setup and operation, as they do not allow for differentiation between assignable controllers within a mobile device interface.
Innovation Solution
A coordinator device that communicates wirelessly with controller devices and a mobile device to identify and differentiate assignable controllers through unique device types and input elements, allowing for dynamic assignment of device types and default reactions, and highlighting corresponding representations within a graphical user interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple identical controller devices are used in a bicycle system, then the system can provide redundant control functions and improved reliability, but it becomes difficult to uniquely identify and configure each controller device within the mobile device interface
Solution Approach 1:
The patent divides the identification space by creating distinct device type categories (e.g., front derailleur controller, rear derailleur controller, brake controller). Each controller device is assigned a unique device type that segments the overall controller population into identifiable groups, allowing the mobile device to differentiate between multiple identical controllers through their functional classification.
Solution Approach 2:
The patent applies local quality by assigning specific characteristics (device type and input element identifiers) to individual controller devices based on their location and function. Each controller has unique local identifiers that reflect its specific role in the bicycle system, enabling the mobile device interface to present differentiated configuration options for each controller even when they share the same hardware form factor.
2Measurement precision
If controller devices are assigned unique device types and input element identifiers, then each controller can be precisely identified and configured, but the system complexity and data management requirements increase
Solution Approach 1:
The patent resolves the complexity issue by adding hierarchical dimensions to the identification system. Instead of using a single complex unique identifier, the system creates a multi-dimensional identification structure with device type as the first dimension and input element identifier as the second dimension. This dimensional approach organizes data in a structured hierarchy that improves identification precision while keeping data management systematic and manageable.
3Loss of information
If the mobile device interface displays representations of multiple controller devices, then users can visually identify and configure each controller, but the interface complexity and user cognitive load increase
Solution Approach 1:
The patent employs visual differentiation techniques where controller device representations in the mobile device interface are distinguished through visual attributes such as color coding, icons, or graphical indicators corresponding to their device types. This allows users to quickly identify and differentiate between multiple controller devices without requiring complex interface structures or increasing cognitive load, as the visual cues provide immediate identity information.
Data Source
AI summary
A coordinator device for a bicycle includes a processor configured to receive a signal generated in response to user input at an input element from a controller device. The signal includes data identifying a device type and data identifying the input element. The coordinator device includes a memory configured to store the data identifying the device type and the data identifying the input element. The processor is configured to generate a notification based on the received signal, transmit the generated notification to the mobile device, and in response to the transmission of the generated notification, receive a request for data related to the received signal from the mobile device. The processor is further configured, in response to the request, to transmit the stored data to the mobile device, such that an association of the controller device with the representation of the controller device is identifiable within the GUI at the mobile device.
