Solution Overview

Problem

Motorcycle riders face challenges with flexible bags lacking secure fastening and access control, especially during short stops, where unauthorized access and theft are concerns.

Innovation Solution

A bag design featuring a plate with movable stop elements and fixing elements, including a lockable mechanism to secure the bag to a motorcycle, ensuring it cannot be easily accessed or removed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If flexible bags are used on motorcycles, then ease of attachment and flexibility are improved, but security against unauthorized access and theft deteriorates

Engineering Contradiction:
Improveease of attachmentVSAvoidsecurity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent combines the flexible bag with a rigid plate structure that integrates both attachment functions (to the motorcycle) and security functions (locking mechanism). The plate serves as a unified structure that merges the previously separate attachment system and security system into a single integrated component, allowing the flexible bag to benefit from both ease of attachment and enhanced security.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention uses a composite structure combining a flexible bag material with a rigid plate. This composite design allows different parts of the system to have different properties: the flexible bag provides adaptability and ease of attachment, while the rigid plate provides structural strength and security against unauthorized access.

Inventive Principle:
Principle #40Composite materials

2Reliability

If a lockable mechanism is added to flexible bags, then security is improved, but device complexity increases

Engineering Contradiction:
ImprovesecurityVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The locking mechanism is merged with the attachment plate structure rather than being a separate component. The stop elements are integrated into the plate, and the lock works in conjunction with the existing fixing elements, reducing overall system complexity compared to adding a completely separate locking system.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The plate structure serves multiple functions: it provides attachment points to the motorcycle, houses the locking mechanism, and supports the flexible bag. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If stop elements are made movable between releasing and retaining positions, then security control is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvesecurity controlVSAvoidease of access
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The stop elements are designed to be manually movable by the user without requiring additional tools or complex mechanisms. The user can easily switch between the releasing position (for access) and the retaining position (for security) by simple manual operation, making the system self-servicing and easy to use.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The stop elements are made dynamic rather than fixed, allowing them to move between two distinct positions. This dynamic capability enables the system to adapt between security and access modes, providing security control when needed while maintaining ease of access when required.

Inventive Principle:
Principle #15Dynamics

AI summary

The bag for motorcycles comprises at least one closing element (2) for closing the bag (1) and a plate (3) that includes at least one housing (4) for housing said at least one closing element (2), and at least one stop element (5) that is movable between a releasing position and a retaining position, so that in the releasing position the at least one closing element (2) can be removed from the at least one housing (4) and in the retaining position the at least one closing element (2) is prevented to be removed from the at least one housing (4). It permits to provide a bag for motorcycles that provides an enhanced security, permitting to fix the bag to the motorcycle in a secure way and also closing the bag for prevent or reduce the risk of an unauthorized access to the bag.
