Bicycle Brake Lever Base with Multi-Component Mounting Interface
Solution Overview
Problem
Users of human-powered vehicles face difficulty in operating additional components simultaneously with the brake operating device, as described in Japanese Patent Application Laid-Open No. H1-132488, due to limited accessibility and connectivity.
Innovation Solution
An operating device with a base member and an operating member, featuring first and second connecting parts for a power transmitting medium, allows users to easily operate additional components by providing them on the base or operating member, enabling shared power transmission and easy access, with options for pivotal operation, removability, and positioning on the handlebar for enhanced usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional components are added to the operating device, then functionality and versatility are improved, but device complexity increases
Solution Approach 1:
The base member is designed as a universal platform that can accommodate multiple different additional components (transmission operating device, driving unit mode selector, suspension operating device, adjustable seatpost operating device, system information display) through standardized mounting interfaces, allowing one component to serve multiple functions
2Productivity
If additional components are integrated into the operating device, then operational efficiency is improved, but ease of operation deteriorates due to limited accessibility
Solution Approach 1:
The additional components are arranged in the vertical dimension on the base member, extending upward from the handlebar area, allowing users to access components by reaching upward rather than requiring horizontal space, thus maintaining ease of operation while integrating multiple functions
3Adaptability or versatility
If multiple connecting parts are provided for power transmitting medium, then adaptability and connectivity are improved, but device complexity increases
Solution Approach 1:
The base member incorporates multiple standardized connecting parts (first connecting part, second connecting part, etc.) that can connect to different power transmitting media (hydraulic fluid lines, Bowden cables), creating a universal interface that simplifies connectivity across different component types

AI summary
An operating device includes a base member, an operating member, a first connecting part, a second connecting part and an additional component. The base member is mounted on a human-powered vehicle; an operating member provided to the base member. The first connecting part is provided to one of the base member and the operating member in a manner connectable to a power transmitting medium. The second connecting part is provided to the base member in a manner connectable to the power transmitting medium. The additional component is provided to at least one of the base member and the operating member.
