Two-Wheeler Lock Hardened Protective Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing two-wheeler locks made from hardened materials are costly and heavy, making them undesirable due to increased manufacturing complexity and weight, which complicates their production and use.
Innovation Solution
A two-wheeler lock design featuring a protective device made of a harder material, such as hardened metal or ceramic, strategically placed on the fastening section to prevent cutting or sawing, allowing the rest of the lock body to be made from a lighter, easier-to-process material, thereby reducing production costs and weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lock body is made from hardened material to prevent cutting or sawing, then security against forced opening is improved, but weight and manufacturing cost increase
Solution Approach 1:
The patent applies local quality by providing a protective device made of hardened material only at specific critical locations (fastening section and attachment section) rather than hardening the entire lock body. This localized approach maintains security where most needed while reducing overall weight and manufacturing complexity.
Solution Approach 2:
The lock body is segmented into different material zones: a protective device made of hardened second material at critical areas, and the remaining lock body made of lighter first material. This segmentation allows optimization of both security and weight by assigning different material properties to different functional regions.
2Reliability
If the lock body is made from hardened material to prevent cutting or sawing, then security against forced opening is improved, but manufacturing complexity and cost increase
Solution Approach 1:
Instead of uniformly hardening the entire lock body which would require complex manufacturing processes, the patent applies protective devices only at critical locations. This reduces manufacturing complexity by limiting the scope of hardening operations to specific areas where security is most critical.
Solution Approach 2:
The manufacturing process is segmented into separate steps: producing the lock body from lighter material, then adding protective devices at critical locations. This segmentation simplifies overall manufacturing compared to producing an entirely hardened lock body, as it allows use of different manufacturing techniques optimized for each component.
3Reliability
If the lock body is made from hardened material to prevent cutting or sawing, then security against forced opening is improved, but production cost increases
Solution Approach 1:
The patent reduces production cost by applying expensive hardened material only where absolutely necessary for security (critical fastening and attachment points) rather than throughout the entire lock body. This localized approach significantly reduces material costs and manufacturing expenses while maintaining adequate security.
Solution Approach 2:
The production cost is segmented into two components: cost-effective lighter material for the main lock body structure, and expensive hardened material only for protective devices at critical locations. This segmentation optimizes the cost-benefit ratio by allocating high-cost materials only where they provide maximum security value.

AI summary
A two-wheel lock (10) comprises a lock body (12) and an elongated locking element (20), wherein the lock body (12) has a housing section (14) which houses a locking mechanism and a fastening section (16) adjacent to the housing section (14) which is formed from a first material, wherein a first end (30) of the locking element (20) is attached to the fastening section (16) of the lock body (12) and a second end (32) of the locking element (20) is selectively lockable to the lock body (12).The two-wheel lock is characterized by the fact that a protective device (54) made of a second material, which has a greater hardness than the first material, is provided on the fastening section (16) of the lock body (12), wherein the protective device (54) is arranged between the first end (30) of the locking element (20) and the housing section (14) of the lock body (12) in order to make it more difficult to cut through the fastening section (16) of the lock body (12).
