Bicycle Brake Warning Device with Wireless Tip Lights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bicycles, electric bicycles, and motorcycles lack recognizable safety indicators, making it difficult for rear vehicles to understand the braking intentions of the front vehicles, leading to potential rear-end collisions, especially in densely populated urban areas.
Innovation Solution
A brake warning device mounted between the bicycle handle and brake horn, featuring a moving portion with thimble blocks and springs, a sensory switch, and multiple tip lights with wireless communication, which illuminates when the brake horn is activated, providing a clear visual reminder of the braking intention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a brake warning device is installed on the bicycle handle, then the braking intention visibility is improved, but the device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical brake signal transmission with a wireless communication system. The sensory switch detects brake horn activation mechanically, but the signal is transmitted wirelessly via radio frequency to the tip light, eliminating the need for complex wired connections and reducing overall system complexity while improving reliability
Solution Approach 2:
The patent introduces a wireless signal as an intermediary between the brake horn activation and the tip light illumination. The sensory switch converts mechanical brake action into an electrical signal, which is then transmitted wirelessly to trigger the tip light, creating a simplified intermediary communication path that resolves the contradiction between visibility and complexity
2Area of stationary object
If multiple tip lights are distributed on the bicycle, then the braking indication coverage is improved, but the manufacturing cost increases
Solution Approach 1:
The patent divides the braking indication system into multiple independent tip lights positioned at different locations on the bicycle (front, rear, and sides). Each tip light is a separate, modular unit that can be manufactured independently and installed separately, allowing the system to achieve comprehensive coverage while maintaining ease of manufacture through standardized modular components
Solution Approach 2:
The patent designs the tip lights to serve multiple functions: they indicate braking intention, provide visibility enhancement, and can be positioned at various locations on the bicycle. The wireless communication system allows a single control unit to manage multiple tip lights, reducing the need for separate control circuits and lowering overall manufacturing cost despite the increased number of light units

Function Achieved in This Case
Enhances safety by providing a clear visual indication of the braking intention, reducing the risk of rear-end collisions through a three-dimensional display of brake light signals, without requiring modifications to the vehicle or power connections, thus improving human safety.
Implementation Method 1
a first thimble, a thimble spring, a second thimble and a protective outer spring, the first thimble fixing block and the second thimble fixing block are embedded to form one and connected to the brake horn
