Solution Overview
Problem
Current bicycle operating devices lack a clear and distinct method to differentiate between different user input operations, leading to confusion and inefficient control of bicycle components.
Innovation Solution
A bicycle operating device comprising a base member, a switch structure with two electrical switches, and an operating structure with an intermediate structure that includes cams and followers to transmit distinct movements of an operating member to the switches, generating different signal patterns for each user input operation, allowing for clear differentiation and control of bicycle components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single switch structure is used in conventional bicycle operating devices, then the device complexity is reduced, but the ability to differentiate between different user input operations deteriorates
Solution Approach 1:
The switch structure is divided into multiple independent electrical switches (first electrical switch, second electrical switch, third electrical switch), each capable of being actuated by different movements of the operating member. This segmentation allows each switch to respond to specific input operations, enabling the system to differentiate between various user inputs while maintaining a relatively simple overall structure.
2Adaptability or versatility
If an operating member with multiple movement capabilities is implemented, then the versatility of control operations is improved, but the ease of operation deteriorates due to increased complexity
Solution Approach 1:
Different portions of the operating member are designed with distinct functional characteristics to produce different types of movements (first movement, second movement, third movement). Each movement type is optimized for a specific operation, allowing users to intuitively differentiate between input operations based on the direction and nature of the movement, thereby maintaining ease of operation despite multiple control functions.
3Measurement precision
If multiple electrical switches are used to generate different signal patterns, then the measurement precision of user input operations is improved, but the device complexity increases
Solution Approach 1:
The operating member serves multiple functions by being capable of producing different movements (first, second, and third movements) that respectively actuate different electrical switches. This multi-functionality allows a single operating member to provide precise detection of various user input operations without requiring separate operating mechanisms for each function, thereby limiting the increase in device complexity.

AI summary
A bicycle operating device comprises a base member, a switch structure, an operating structure, and a controller. The switch structure comprises a first electrical switch and a second electrical switch. The first electrical switch has a first operated state. The second electrical switch has a second operated state. The operating structure includes an operating member. The controller is configured to respectively generate a first control signal and a second control signal based on a first signal pattern and a second signal pattern. The first signal pattern includes a first combination of the first operated state and the second operated state. The second signal pattern including a second combination of the first operated state and the second operated state. The second combination is different from the first combination.
