Solution Overview

Problem

Existing passenger protection structures on bicycles, particularly those for children, are difficult to access and secure, especially when installed on luggage racks, posing challenges for easy boarding and safety during transport.

Innovation Solution

A pivoting passenger protection structure that can pivot to clear the sides of the luggage rack, allowing easy boarding and securing passengers, equipped with locking mechanisms that engage automatically and require manual release for unlocking, and optionally includes a soft top and canopy for enhanced protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the protection structure is fixed and bolted to the luggage rack, then safety and stability during transport is improved, but ease of boarding and access to the luggage rack deteriorates

Engineering Contradiction:
Improvesafety during transportVSAvoidease of boarding
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The protection structure is designed to pivot between a first position (open) that facilitates boarding and a second position (closed) that provides safety during transport. The structure includes pivot points and locking mechanisms that enable it to transition between these positions, resolving the contradiction between ease of access and safety stability.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the protection structure is positioned high on the luggage rack, then safety protection is improved, but ease of access for passengers deteriorates

Engineering Contradiction:
Improveprotection against impactsVSAvoidease of access
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The structure pivots to clear the sides of the luggage rack when in the first position, allowing passengers easy access to board. When closed, it returns to its protective position surrounding the passengers. This dynamic positioning resolves the contradiction between high protective positioning and ease of access.

Inventive Principle:
Principle #15Dynamics

3Reliability

If locking mechanisms require manual action to unlock, then safety and security is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvesecurity during transportVSAvoidease of unlocking
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The locking mechanisms are designed to engage automatically when the protection structure is closed, eliminating the need for manual locking action. The structure itself performs the locking function through its movement, while manual action is only required for unlocking when needed. This resolves the contradiction between automatic security engagement and ease of operation.

Inventive Principle:
Principle #25Self-service
