Modular Bicycle Shifter with Separable Base Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle component operating devices lack flexibility in controlling multiple bicycle components simultaneously, often requiring separate devices for different functions and lacking a compact, user-friendly configuration.
Innovation Solution
A bicycle component operating device with a modular design featuring a first and second actuation unit, allowing configuration between three modes: integrated control of two components, single component control, or independent control of each component, using pivotally mounted members and separable base members with coaxial axes and threaded fasteners for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single integrated operating device is used to control multiple bicycle components, then device integration and space saving are improved, but flexibility and ease of configuration for different user preferences deteriorate
Solution Approach 1:
The operating device is divided into separate modular units (first operating member with first base member, second operating member with second base member) that can be independently configured. Each module can be separately mounted or combined, allowing users to choose different configuration modes (single component control, dual component control, or independent control) based on their preferences, thus maintaining flexibility while achieving integration when needed.
2Adaptability or versatility
If separate operating devices are used for different bicycle components, then functional specialization is improved, but device complexity and space requirements worsen
Solution Approach 1:
The operating device design allows each base member to serve multiple functions - the first base member can control the first bicycle component alone, the second base member can control the second bicycle component alone, or both can be integrated to control multiple components simultaneously. This multi-functionality reduces the need for separate dedicated devices while maintaining functional specialization.
3Stability of the object's composition
If base members are permanently attached, then structural stability is improved, but ease of configuration and adaptability worsen
Solution Approach 1:
The attachment between base members is designed to be dynamically changeable rather than fixed. The base members can be separably attached or detached, allowing the structure to transition between different configuration states (integrated or separate) based on user needs, thus maintaining both structural stability when attached and configuration flexibility when needed.

AI summary
A bicycle component operating device is basically provided with a first base member, a first operating member, a second base member and a second operating member. The first operating member is pivotally mounted to the first base member to pivot about a first axis to control a first bicycle component. The second base member is different from the first base member. The second base member is separably attached to the first base member along an axial direction parallel to the first axis. The second operating member is pivotally mounted to the second base member to control a second bicycle component that is different from the first bicycle component. The first operating member remains with the first base member and the second operating member remains with the second base member upon separation of the first base member from the second base member.
