Detachable Assist Switch Coupling for Handlebar Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Human-powered vehicles with electric components face challenges in operability and flexibility due to complex structures and direct mounting requirements, which hinder the efficient integration and arrangement of assist operating switches.
Innovation Solution
The operating switch device features a detachable coupling structure that allows the assist operating switch to be easily coupled to a base member mounted on the handlebar, providing a simple and flexible arrangement without direct attachment to the handlebar, using fasteners, convex portions, and recesses for secure detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the assist operating switch is directly mounted to the handlebar, then the mounting structure is simple, but the flexibility and operability of the assist driving unit deteriorates
Solution Approach 1:
The operating device is divided into separate functional modules: the base member mounted on the handlebar, and the assist operating switch that can be detachably coupled to the base member. This segmentation allows the switch to be independently positioned and adjusted, improving flexibility while maintaining a relatively simple overall structure.
Solution Approach 2:
The coupling structure enables dynamic reconfiguration of the assist operating switch relative to the base member. The switch can be detached and reattached at different positions, allowing the system to adapt to different operational requirements and user preferences, thereby enhancing versatility without complicating the fundamental mounting approach.
2Adaptability or versatility
If the assist operating switch is detachably coupled to the base member, then the operability and flexibility of the assist driving unit is improved, but the device complexity increases
Solution Approach 1:
The coupling structure is designed with universal coupling elements (convex portions and recesses) that can accommodate different switch configurations and positions. This universal design approach allows the same coupling mechanism to serve multiple functions: securing the switch, allowing easy detachment, and enabling repositioning, thereby improving operability without proportionally increasing complexity.
Solution Approach 2:
The base member acts as an intermediary component between the handlebar and the assist operating switch. This intermediate coupling point simplifies the overall structure by providing a standardized interface, reducing the need for complex direct mounting mechanisms while maintaining ease of attachment and detachment.
3Device complexity
If multiple operating switches are integrated into a single operating device, then the structural complexity is reduced, but the arrangement flexibility of individual switches deteriorates
Solution Approach 1:
Each operating switch is designed as a separate detachable module that can be independently coupled to the base member. This segmentation maintains low structural complexity by using a standardized base member for all switches, while simultaneously enabling flexible arrangement as each switch can be positioned and adjusted independently according to operational needs.

AI summary
An operating switch device for a human-powered vehicle comprises an assist operating switch and a coupling structure. The assist operating switch is configured to receive a user operation input to operate an assist driving unit configured to assist a human power. The coupling structure is configured to detachably couple the assist operating switch to a base member of an operating device configured to be mounted to a handlebar. The base member includes a base body including a grip portion provided between a coupling end configured to be coupled to the handlebar and a free end opposite to the coupling end.
