Bicycle Bell Housing for Hidden Anti-Theft Positioner Mounting

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing bicycle bells lack a hidden positioning system that prevents theft by concealing positioners, making it easy for thieves to remove and steal bicycles.

Innovation Solution

A bell with a mountable positioner that includes a chamber to accommodate and protect positioners of varying sizes, featuring a waterproof rubber ring and a sound trigger mechanism, ensuring the positioner is securely housed and protected within the bell.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the positioner is installed on the bicycle surface in easy-to-find positions, then the installation is simple and accessible, but the positioner can be easily removed by thieves

Engineering Contradiction:

Improveinstallation accessibilityVSAvoidanti-theft security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The positioner is nested inside the bell housing, placing it within an existing structure rather than on the external bicycle surface. This concealment makes it difficult for thieves to locate and remove the positioner, while the bell itself serves as the protective outer shell

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The bell acts as an intermediary structure between the bicycle and the positioner. Instead of directly mounting the positioner on the bicycle frame, it is installed within the bell, which provides both concealment and structural protection

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the bell structure is designed to accommodate positioners, then hidden locating effect is achieved, but the bell structure becomes more complex

Engineering Contradiction:

Improveanti-theft securityVSAvoidbell structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The bell is designed with multi-functionality: it serves both as the traditional warning bell and as a protective housing for the positioner. The chamber that would otherwise be empty or used for simple bell components is repurposed to accommodate the positioner, eliminating the need for a separate protective structure

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The positioner housing and bell structure are merged into a single integrated component. The chamber within the bell is designed to receive and protect the positioner, combining two functions (bell operation and positioner protection) into one structure rather than using separate components

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If the chamber space is made large enough to accommodate positioners of different sizes, then adaptability is improved, but the bell volume increases

Engineering Contradiction:

Improvepositioner size compatibilityVSAvoidbell volume

Core Design Contradiction:

Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The positioner mounting system uses adjustable and flexible components including elastic frames and adjustable fastening mechanisms. This allows the same chamber to adapt to different positioner sizes without requiring a larger fixed volume, as the internal components can be adjusted to fit various dimensions

Inventive Principle:

Principle #15Dynamics

AI summary

A bell having mountable positioner for bicycle is provided, including a fixing element configured to secure to a handlebar of the bicycle, a sound element configured to generating a bell sound, a sound trigger configured to knock the sound element, and a chamber configured to accommodate and protect the mountable positioner. The sound element and the sound trigger are assembled together to form the chamber. A waterproof rubber ring is arranged on a sound trigger member and is located in the chamber for accommodating and protecting the mountable positioner therein. A space of the chamber is configured to accommodate the mountable positioners of different sizes.
