Removable Cargo Module Coupling for Axle-Free Stabilizer Cycles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tricycles with load-carrying devices have limited loading flexibility due to rear wheels obstructing lateral loading and lack of a removable load-carrying system, leading to inefficiencies in delivery operations.
Innovation Solution
A bicycle or tricycle with a removable load-carrying device that attaches to the chassis via a coupling system, allowing the load-carrying device to be easily mounted and dismounted, and featuring a pendulum-like stabilizer system with a free space between rear wheels for unobstructed loading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the load-carrying device is fixed to the chassis, then the vehicle structure is stable, but the loading flexibility and delivery efficiency deteriorate due to inability to quickly remove or exchange load-carrying devices
Solution Approach 1:
The load-carrying device is separated from the chassis into two independent parts: a fixed coupling part on the chassis and a removable coupling part on the load-carrying device. This segmentation allows the load-carrying device to be quickly attached and detached while maintaining structural stability when connected, resolving the contradiction between loading flexibility and device complexity.
2Stability of the object's composition
If the rear wheels are positioned close together for stability, then the vehicle stability is improved, but the loading space between the rear wheels deteriorates, making lateral loading difficult
Solution Approach 1:
The load-carrying device is designed to be positioned in the free space between the rear wheels, utilizing the lateral dimension rather than requiring additional longitudinal space. This allows loading operations to occur in the available gap between wheels without compromising vehicle stability, effectively using dimensional space optimization to resolve the contradiction.
3Stability of the object's composition
If the load-carrying device is positioned low for better vehicle behavior in turns, then the dynamic stability is improved, but the ease of loading deteriorates due to obstacles posed by rear wheels during lateral loading
Solution Approach 1:
The coupling system acts as an intermediary mechanism that enables the load-carrying device to be easily attached and detached despite the low positioning. The quick-coupling mechanism compensates for the reduced accessibility caused by low positioning, allowing operators to quickly load and unload without needing to maneuver around rear wheel obstacles, thus maintaining ease of operation while achieving dynamic stability.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances loading flexibility and delivery efficiency by allowing third parties to load and unload the load-carrying device during vehicle motion, reducing downtime and increasing the number of trips.
Implementation Method 1
the said stabilizer system is pendulum, the first arm and the second arm being configured to be articulated to the chassis in such a way as to allow the chassis to tilt in turns
Implementation Method 2
the first coupling part and the second coupling part form, in the coupling position, a pivot joint along an articulation axis between the chassis and the load-carrying device, articulation axis around which the load-carrying device is configured to pivot relative to the chassis
