Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional control and display systems on electric bicycles are awkward to use and provide limited information, making it difficult for riders to effectively control and monitor the e-bike's operations while riding.
Innovation Solution
A control device with an LED indicator and angled surfaces for comfortable button engagement, paired with a display device that presents alphanumeric and status information, allowing riders to easily select peddle assist levels and view e-bike status, including battery charge and error codes, via a user-friendly interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional control and display systems are used on electric bicycles, then the device structure remains simple, but the ease of operation deteriorates and limited information can be presented
Solution Approach 1:
The control system is divided into separate functional modules: a control device with buttons for input, an LED indicator for basic feedback, and a separate display device for detailed information. This segmentation allows each component to be optimized independently while working together to improve overall usability without overwhelming complexity in a single integrated unit.
Solution Approach 2:
The patent introduces an intermediary communication interface between the control device and display device, allowing information to be transmitted wirelessly or via connection. This intermediary layer enables the display device to provide comprehensive information while keeping the control device simple and easy to operate.
2Quantity of substance
If conventional display interfaces are used, then the device remains compact, but the quantity of information presented deteriorates
Solution Approach 1:
The patent transitions from a single-dimensional compact display to a multi-dimensional information presentation system. The display device can show multiple lines of text, alphanumeric characters, and graphical indicators simultaneously, effectively using vertical and horizontal dimensions to present comprehensive information about battery charge, motor status, and other e-bike parameters.
3Ease of operation
If information is displayed at a distance from the rider, then the display device can be larger, but the ease of operation deteriorates due to difficulty in reading
Solution Approach 1:
The patent applies local quality by positioning the LED indicator and critical information display elements in close proximity to the rider's hands and viewing position. The control buttons are strategically placed on the handlebar within easy reach, while the display device positions information at optimal viewing distances and angles for the rider to easily read while operating the e-bike.

Implementation Method 1
The control device includes an LED indicator that presents information to a rider
Data Source
AI summary
An electric bicycle control device, and associated display device, are described. The control device, in some embodiments, includes an LED (light emitting diode) indicator (e.g., alphanumeric display) that presents information to riders of the electric bicycle, as well as various control buttons that facilitate rider control of the electric bicycle. The control device is associated with a display device, which presents additional or complementary information about the electric bicycle, such as information that is presented based on input received via the control device from the rider.
