Innovation Solution
A hybrid wired/wireless e-bike control system that includes a frame-mounted interface with a processor, wired communication to the e-bike motor system, and wireless communication with handlebar-mounted controls, enabling control of the e-bike motor and display of characteristics like battery power and gear indication, while reducing the risk of failure and space competition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless control devices are mounted on the handlebar, then ease of operation is improved, but device complexity increases due to integration challenges with wired systems
Solution Approach 1:
The patent introduces a wireless communication interface as an intermediary component that bridges the wired control system and wireless control devices. This intermediary handles protocol conversion and data routing, allowing wireless controls to integrate seamlessly with the existing wired architecture without requiring complete system redesign.
Solution Approach 2:
The control system is segmented into independent communication modules: a wired communication interface connected to the controller, and separate wireless communication interfaces connected to various control devices. This modular segmentation allows each component to be optimized independently while maintaining overall system functionality.
2Reliability
If wired connections are used for control and display, then reliability is improved, but ease of operation deteriorates due to movement and space competition on handlebar
Solution Approach 1:
The patent replaces mechanical wired connections with wireless communication protocols for control devices mounted on the handlebar. This substitution eliminates physical cables that compete for space and can fail due to movement, while maintaining reliable communication through radio frequency links with error correction and retransmission capabilities.
3Adaptability or versatility
If a comprehensive communication bridge is implemented between wired and wireless components, then adaptability is improved, but device complexity increases
Solution Approach 1:
The communication bridge is designed with universal interfaces that support multiple wireless protocols (Bluetooth, Wi-Fi, Zigbee) and wired connections simultaneously. This multi-functional design allows the same hardware platform to adapt to different control devices and communication standards without requiring protocol-specific hardware variants.
