Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional electric bicycles have separate throttle and shifter components on the handlebar, leading to a large distance between them, making it difficult to operate both simultaneously, which poses safety risks due to potential misalignment during braking.

Innovation Solution

A handle component that integrates a shifter and throttle, featuring a shifter body, throttle body, resilient element, and control module, allowing the throttle body to rotate relative to the shifter body, with a sensor to control the motor operation, reducing finger movement distance and enhancing safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the throttle and shifter are mounted as two independent components on the handlebar, then each component can be protected by its own shell, but the distance between the shifter and throttle trigger becomes too large for safe operation

Engineering Contradiction:

ImprovesafetyVSAvoidfinger movement distance

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent integrates the throttle body and shifter body into a single unified structure where the throttle body is disposed inside the shifter body. This merging of previously separate components reduces the distance between the throttle trigger and shifter, allowing riders to operate both controls simultaneously without compromising safety or ease of use.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The throttle body is nested inside the shifter body, with the throttle trigger positioned within the shifter's operational space. This nesting arrangement minimizes the overall footprint and reduces the distance between controls while maintaining independent functionality of both the throttle and shifter mechanisms.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Ease of operation

If the throttle body is integrated inside the shifter body, then the distance between controls is reduced for safer operation, but the structural complexity of the handle component increases

Engineering Contradiction:

Improvefinger movement distanceVSAvoidcomponent integration structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The integrated handle component is divided into distinct functional modules: the shifter body with its shell and cover, the throttle body with its trigger and sliding block, and the resilient element. This segmentation allows each module to be manufactured and assembled separately, reducing overall structural complexity while maintaining the integrated benefits of reduced control distance.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The resilient element acts as an intermediary mechanism between the throttle body and shifter body, providing the necessary mechanical connection and restoring force. This intermediary component simplifies the integration structure by using a simple spring mechanism rather than complex linkages or actuators to connect the two bodies.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A handle component for an electric bicycle has a shifter body, a throttle body, a shifter handle, a resilient element connected to the throttle body and the shifter body, and a control module. The shifter body has a shell and a cover; the shell has a mounting groove and a mounting cylinder respectively formed on its two opposite sides, and the cover is connected to the shell and covers a groove opening of the mounting groove. The throttle body is disposed inside the mounting groove and is configured to be rotated relative to the shifter body. The shifter handle is rotatably sheathed on the mounting cylinder, and the control module is configured to sense rotation of the throttle body to control a motor. By integrating the shifter body and the throttle body, a length of the handle component can be shortened for improving convenience and safety.
