Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for carrying bicycles in challenging terrain, such as steep or uneven mountain bike routes, require disassembly, foldable backpacks, or uncomfortable load distribution, limiting hands-free transport and safety, especially in narrow passages.

Innovation Solution

A backpack carrying system with a rigid frame, shoulder straps, and a hip belt, featuring two spatially separated hooks that allow for hands-free, upright carriage of bicycles without disassembly, ensuring stability and safety through a favorable center of gravity and secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the bicycle is carried on the back using a backpack system, then hands-free transport is achieved, but the bicycle may sway back and forth and cannot be securely fixed

Engineering Contradiction:

Improvehands-free transportVSAvoidsecure fixation

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The fixation system is divided into multiple independent anchorages (first and second anchorages) positioned at different locations on the backpack frame. These anchorages work together to secure the bicycle at multiple points, preventing swaying and ensuring reliable fixation while maintaining hands-free operation

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bicycle is nested within the backpack carrying system, with the frame of the bicycle positioned between the backpack and the anchorages. The anchorages engage with specific parts of the bicycle frame, creating a nested configuration that secures the bicycle firmly to the backpack

Inventive Principle:

Principle #7Nested doll (Nesting)

2Adaptability or versatility

If the bicycle is carried upright with front wheel upwards, then passage through narrow areas is enabled, but the center of gravity must be precisely positioned to maintain balance

Engineering Contradiction:

Improvepassage through narrow areasVSAvoidbalance

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The bicycle is oriented vertically in the third dimension (upright position with front wheel upwards), transforming the carrying configuration from horizontal to vertical. This dimensional change enables passage through narrow areas while the anchorages and frame structure maintain balance by distributing forces along the vertical axis

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If the bicycle is carried on narrow paths, then mobility in challenging terrain is achieved, but safety is compromised if the bicycle cannot be quickly removed

Engineering Contradiction:

Improvemobility in narrow pathsVSAvoidsafety risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The anchorages are designed to be quickly releasable, transforming the fixation system from static to dynamic. This allows the bicycle to be rapidly removed when needed for safety reasons while maintaining secure fixation during normal carrying, enabling adaptive response to changing terrain conditions

Inventive Principle:

Principle #15Dynamics
