Loop Lock with Deflection Device for Simplified Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing loop locks are cumbersome to operate and lack intuitive use, requiring two-stage actuation and risking accidental release or damage due to complex manipulation, especially when securing large-diameter objects like motorcycles.
Innovation Solution
A loop lock design featuring a deflection device that converts rotary movement of the lock cylinder into rotary movement of the locking sleeve, eliminating the need for additional rotary controls and enhancing security by protecting the locking mechanism within a closed housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a two-stage actuation mechanism is used to lock and release the bolt, then the locking mechanism can be secured, but the operation becomes cumbersome and non-intuitive
Solution Approach 1:
The patent combines the lock cylinder rotation and locking sleeve rotation into a single unified operation. The locking sleeve is coupled to the cylinder core such that rotating the lock cylinder simultaneously rotates both the cylinder core and the locking sleeve, eliminating the need for separate two-stage actuation while maintaining secure locking through the ball receiving openings mechanism
2Ease of operation
If the locking sleeve is made rotatable for bolt locking, then the bolt can be easily locked and released, but the mechanism becomes vulnerable to unauthorized manipulation
Solution Approach 1:
The patent introduces the lock cylinder as an intermediary component between the user and the locking sleeve. The cylinder core acts as a mediator that controls the rotation of the locking sleeve through the deflection device, allowing easy operation while preventing direct unauthorized manipulation of the locking sleeve itself
3Volume of moving object
If the lock body is designed with a compact form factor, then the overall size is reduced, but the internal mechanism space is limited
Solution Approach 1:
The patent implements a nested arrangement where the locking sleeve is positioned within the lock body, the cylinder core is nested within the cylinder housing, and the deflection device is integrated within the existing structure. This nesting allows the complex internal mechanism to fit within a compact lock body volume
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design simplifies operation, ensures high security by preventing unauthorized manipulation, and maintains a compact form factor while allowing coaxial alignment of loop ends for secure object engagement.
Implementation Method 1
a deflection device is effective between the cylinder core of the locking cylinder and the locking sleeve, which converts a rotary movement of the cylinder (about the cylinder axis) into a rotary movement of the locking sleeve (about the main axis of the lock body) deflects
Implementation Method 2
The locking sleeve has a plurality of ball receiving openings distributed around the circumference, in which a respective locking ball is mounted. In the locking position of the locking sleeve, the locking balls are pushed radially inwards, while in a release position of the locking sleeve, the locking balls are released radially outwards

AI summary
The lock has a lock body (11) with a piston retainer (73) comprising a lock bush rotatable around a major axis (A) between a locking position and a releasing position. The lock body has a lock cylinder arranged along the major axis between the piston retainer and a mounting portion (71). The lock cylinder has a cylinder core rotatable around a cylinder axis that is aligned vertical to the major axis. A turning device is arranged between the cylinder core and the lock bush and converts the rotating movement of the cylinder core into a rotating movement of the lock bush.
