Solution Overview

Problem

Existing bicycle mounting systems face challenges in accommodating different bicycle dimensions and configurations, particularly when positioning a child seat, as they often require custom lengths and angles, and can create instability by placing the child's weight over the rear wheel or interfere with the top tube.

Innovation Solution

A versatile mounting kit comprising a mounting bar and bracket that can couple to both the head tube and top tube of a bicycle, with adjustable body portions and adaptable bracket surfaces to accommodate various bicycle sizes and shapes, allowing for secure attachment of accessories like child seats or pet carriers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the mounting bar is configured with fixed length and angle, then the manufacturing is simple, but it cannot accommodate various bicycle dimensions and configurations

Engineering Contradiction:

Improveaccommodation of various bicycle dimensionsVSAvoidmounting bar configuration complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mounting bar is divided into multiple adjustable segments or sections that can be configured in different lengths and angles. Each segment can be independently positioned and secured, allowing the bar to adapt to various bicycle frame geometries while maintaining a relatively simple overall structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The mounting bar incorporates adjustable and reconfigurable elements that allow it to dynamically change its length and angle configuration. This enables the same mounting bar to accommodate different bicycle sizes and top tube positions without requiring multiple specialized bars.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If the child seat is mounted behind the rider adjacent the rear wheel, then the mounting is simple, but it creates instability and observation difficulties

Engineering Contradiction:

Improvemounting simplicityVSAvoidbicycle stability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The mounting system transitions from a rear-mounted configuration (adjacent to rear wheel) to a front-mounted configuration (near head tube or top tube). This dimensional relocation moves the child seat to a position that does not interfere with the rider's weight distribution, maintaining bicycle stability while still providing secure mounting.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If the mounting bar is positioned to accommodate different bicycle top tube positions, then the adaptability increases, but the installation difficulty increases

Engineering Contradiction:

Improvemounting position flexibilityVSAvoidinstallation difficulty

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The mounting bar is designed as a universal component that can interface with multiple bicycle frame types and positions (head tube, top tube, seat tube). By incorporating standardized mounting interfaces and adjustable segments, the same bar can be installed on various bicycle configurations without requiring custom fabrication or complex installation procedures.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A mounting bar, bracket, and kit have been developed such that they can couple to a head tube of the bicycle when in a first configuration and then couple to a top tube of a bicycle when in a second configuration. The bracket may be integral with the mounting bar or may be a separate component.
