Modular Bicycle Lock with Interchangeable Strand Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locks for securing mobile objects, such as bicycles, often have large connection ends, fixed lengths, and limited adaptability, requiring users to purchase multiple locks for different applications and security levels, and are not comfortable to wear as a belt.
Innovation Solution
A lock design featuring a lock element with 180-degree symmetry and separate connection areas, allowing for interchangeable strand elements of varying lengths and security functionalities, including electronic safety arrangements, and wireless communication for remote locking and parameterization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lock element and strand element are firmly connected at one end, then the lock provides secure attachment, but the connection end becomes very large requiring time-consuming threading through openings
Solution Approach 1:
The lock is divided into separate modular components: a lock element and a strand element with distinct connection areas. The lock element has two separate connection areas that can independently engage with locking elements on the strand element, allowing the components to be assembled in different configurations without requiring threading through openings.
2Device complexity
If the lock has a fixed length, then the structure is simple, but users need to purchase multiple locks for different applications
Solution Approach 1:
The lock system allows dynamic reconfiguration by enabling the strand element to be disconnected and reconnected at different positions. The lock element maintains a fixed structure with two connection areas, while the strand element can be arranged in various configurations (loop, straight, angled) by changing how its ends engage with the connection areas, providing variable effective lengths without modifying the lock structure.
3Reliability
If the lock element has large connection ends, then the locking mechanism is robust, but the lock is uncomfortable to wear as a belt
Solution Approach 1:
The lock element features localized connection areas that are robust and well-defined for secure locking engagement, while the main body of the lock element maintains a streamlined, belt-friendly profile. The connection areas are concentrated at specific locations rather than extending along the entire length, allowing the lock to be worn comfortably as a belt while maintaining secure locking capability where needed.
4Device complexity
If the lock provides only cut protection, then the design is simple, but users need additional locks for alarm functionality
Solution Approach 1:
The lock element is designed as a universal platform that can support multiple security functions. It includes a robust locking mechanism for cut protection and integrated alarm functionality that can detect movement or tampering. The modular design allows the same lock element to provide both mechanical security and electronic alarm capabilities, eliminating the need for separate locks for different security needs.
