Modular Two-Wheeler Lock Assembly for Secure Frame Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing two-wheeler locks, such as bicycle locks, often integrate a bolt securing device into the frame lock, increasing complexity and cost, and lack the ability to be used independently.
Innovation Solution
A two-wheeler lock with a locking unit and sleeve that can be attached to the frame, allowing an insertion unit to be anchored to a fixed object, featuring a bolt receiver and a lock cylinder for secure attachment, with optional covers and fixing devices for easy assembly and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bolt securing device is integrated into a frame lock, then the two-wheeler can be secured to a fixed object, but the complexity and manufacturing cost of the frame lock increase
Solution Approach 1:
The locking system is divided into separate functional modules: a frame lock for mounting to the bicycle frame, a separate locking unit with bolt receiver and lock cylinder, and an insertion unit. This segmentation allows each component to be optimized independently and simplifies manufacturing while maintaining security functionality.
Solution Approach 2:
The bolt securing device is extracted from the frame lock and implemented as a separate locking unit that can be independently assembled. This extraction reduces the complexity of the frame lock itself while providing the same security function through a modular approach.
2Reliability
If a bolt securing device is integrated into a frame lock, then the two-wheeler can be secured to a fixed object, but the manufacturing cost increases
Solution Approach 1:
Dividing the locking system into separate manufacturable components allows for specialized production techniques for each part, reducing overall manufacturing cost while maintaining security functionality.
Solution Approach 2:
The locking unit is designed as a universal component that can be used with different frame locks and insertion units, allowing for economies of scale in manufacturing and reducing per-unit costs.
3Ease of repair
If the locking unit is made replaceable, then easy replacement is achieved, but the connection between locking unit and frame must be secure
Solution Approach 1:
The locking unit is pre-equipped with mounting features and fixing devices that enable secure attachment to the frame before use. This preliminary preparation ensures that when the unit is installed, it achieves both secure connection and replaceability without requiring complex installation procedures.

AI summary
A two-wheeler lock includes a locking unit having two opposite end faces, and a sleeve having a longitudinal axis and two opposite axial ends, wherein a bolt receiver is provided at the first end face and a rotatable lock cylinder, which actuates a locking element is provided at the second end face. The sleeve has an end wall at the first axial end and is open at the second axial end, wherein the locking unit can be introduced, with the lock cylinder or the bolt receiver at the front, into the sleeve. In the introduced state, the locking unit can be fixed in the sleeve a fixing device. The end wall of the sleeve has a passage opening for a key to be inserted into the lock cylinder or a bolt to be inserted into the bolt receiver.
