Solution Overview
Problem
Existing human-powered vehicle operating devices face challenges in stably supplying electricity to wireless communicators and efficiently utilizing space for multiple power sources, leading to limitations in power management and component integration.
Innovation Solution
The operating device incorporates a separate secondary electric power source connected to a wireless communicator, with an accommodating structure and electrical contacts to manage power supply, allowing parallel connection and efficient space utilization, and includes a controller for charging and supplying electricity based on state conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single electric power source is used in the operating device, then the device structure is simple, but the wireless communicator cannot be stably supplied with electricity
Solution Approach 1:
The power source system is segmented into two separate electric power sources: a first electric power source for supplying electricity to the controller, and a second electric power source for supplying electricity to the wireless communicator. This segmentation ensures that each component has a dedicated power supply, improving reliability of electricity supply to the wireless communicator while maintaining clear functional separation.
2Reliability
If multiple electric power sources are provided separately, then stable electricity supply is achieved, but the device occupies more space
Solution Approach 1:
The first electric power source and the second electric power source are integrated into a single accommodating structure. This merging approach allows both power sources to be housed together in a compact arrangement, reducing the overall volume of the operating device while maintaining the reliability benefits of having separate power sources for different components.
Solution Approach 2:
The accommodating structure is designed to serve multiple functions: it accommodates both the first electric power source and the second electric power source, and also provides electrical contacts for both power sources. This multi-functionality reduces the need for separate structures for each power source, thereby optimizing space utilization.
3Volume of moving object
If the first electric power source and second electric power source are integrated in the same accommodating structure, then space is efficiently utilized, but electrical connection complexity increases
Solution Approach 1:
The accommodating structure provides locally optimized electrical contacts: a first electrical contact for the first electric power source and a second electrical contact for the second electric power source. Each power source has its own dedicated contact point, which simplifies the electrical connection process while maintaining compact integration within the same accommodating structure.

AI summary
An operating device for a human-powered vehicle comprises a base member, an operating member, an accommodating structure, and a second electric power source. The operating member is movably coupled to the base member. The accommodating structure is configured to accommodate a first electric power source. The second electric power source is electrically connected so as to supply electricity to a wireless communicator. The second electric power source is separate from the first electric power source.
