Solution Overview
Problem
Existing operating devices for human-powered vehicles face challenges in designing a flexible and efficient power storage system that is not obstructed by other components, leading to limitations in size and functionality.
Innovation Solution
The operating device features a power storage system that can be placed in a separate location from the electrical switch and electric generator, allowing for flexible design and placement, including within the operating member or on the base member, and utilizes wireless communication to omit wiring, minimizing power loss with an electric wiring connection and rectification for effective power storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the power storage is integrated with the electrical switch and electric generator in the same housing, then the device structure is compact, but the power storage size is limited and cannot be flexibly designed
Solution Approach 1:
The power storage is separated from the housing containing the electrical switch and electric generator, allowing independent sizing and placement. The power storage can be positioned on the operating member or base member at a different location, enabling flexible design of power storage capacity without being constrained by the housing volume.
2Loss of energy
If wiring is used to connect the power storage to the controller, then electrical connection is reliable, but power loss occurs and wiring complexity increases
Solution Approach 1:
The patent replaces the mechanical/electrical wiring connection with wireless communication technology. The communicator wirelessly transmits operation signals from the controller to the bicycle components, eliminating physical wiring and associated power losses while reducing structural complexity.
