Three-State Closure for Two-Wheeler Storage Theft Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage devices for two-wheelers face challenges in securing the lid against accidental or unauthorized opening while maintaining convenient access and preventing theft, especially when the bicycle is in motion or stationary.
Innovation Solution
A storage device with a closure that can selectively assume a release, secure, and locked state, using a latch and identification means to ensure the lid remains closed securely, and a fastening device that requires tools or identification for detachment, enhancing theft protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a closure with only release and secure states is used, then the lid can be easily opened and closed during brief standstills, but the container cannot be protected against theft when the bicycle is parked
Solution Approach 1:
The closure system dynamically transitions between three states (release, secure, locked) based on operational needs. The bolt can be manually positioned in release or secure states for convenient access during brief standstills, or moved to the locked state for theft protection when parked, allowing the system to adapt its security level to the current situation.
Solution Approach 2:
The closure mechanism is segmented into distinct functional states: release state for easy opening, secure state for preventing accidental opening during motion, and locked state for theft protection. This segmentation allows each state to be optimized for its specific purpose without compromising the others.
2Reliability
If a separate locking device is added to achieve locked state, then theft protection is improved, but the device complexity increases
Solution Approach 1:
The locking function is merged with the existing closure mechanism. The bolt that already exists for release and secure states is extended to provide the locked state function, eliminating the need for a separate locking device. The identification means is integrated into the existing closure housing, further reducing overall system complexity.
Solution Approach 2:
The bolt serves multiple functions: it enables the release state for easy opening, the secure state for preventing accidental opening, and the locked state for theft protection. This multi-functionality eliminates the need for separate components for each state, reducing device complexity while maintaining comprehensive security.
3Ease of operation
If the container can be easily removed from the bicycle, then access to storage space is convenient, but theft protection is reduced
Solution Approach 1:
The fastening device dynamically responds to authentication input. When the correct identification means is provided, the fastening device releases to allow convenient container removal for authorized access. Without proper authentication, the fastening device remains engaged, providing theft protection. This dynamic behavior allows the system to differentiate between authorized and unauthorized access attempts.

AI summary
The present invention relates to a storage device for attachment to a two-wheeled vehicle. In addition to a container and a lid, the storage device comprises a closure designed to selectively assume one of the following three states when the lid is in the closed position: a release state, in which the closure releases the lid for movement to the open position; a securing state, in which the closure secures the lid in the closed position; and a locking state, in which the closure locks the lid in the closed position. The closure is associated with an identification means and is designed such that it can be moved from the securing state to the release state without using the associated identification means, but can only be moved from the locking state to the release state using the associated identification means.
