Steering Column Lock with Rotating Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steering column locks can be bypassed by thieves using tools to rotate the steering column despite the presence of a lock mechanism, allowing them to potentially steer the vehicle without a steering wheel.
Innovation Solution
A freely rotating outer cover is integrated with the steering column lock mechanism, which prevents the lock from being rotated even when grabbed with tools, enhancing security by ensuring the steering column remains stationary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lock mechanism is installed on the steering column to prevent theft, then the security against steering wheel removal is improved, but the lock mechanism itself can be grasped and rotated using tools like pliers or wrenches, allowing the steering column to be rotated and the vehicle to be steered without a steering wheel
Solution Approach 1:
The lock mechanism is divided into two functional segments: an inner locking mechanism that secures the steering column, and an outer cover that is freely rotatable. This segmentation allows the outer cover to be grasped and rotated without transmitting force to the inner locking mechanism, thereby preventing steering column rotation while maintaining the ability to secure the steering wheel.
Solution Approach 2:
The freely rotatable outer cover acts as an intermediary between the thief's tool and the steering column. When a thief attempts to rotate the steering column using pliers or a wrench on the outer cover, the cover rotates independently without transmitting the rotational force to the locking mechanism or steering column, thus neutralizing the harmful effect.
2Reliability
If a lock mechanism is installed to prevent theft, then security is improved, but the device complexity increases due to additional components
Solution Approach 1:
The outer cover serves multiple functions: it provides a grasping surface for removal operations, acts as a protective shield for the locking mechanism, and functions as a freely rotatable element that prevents steering column rotation when grabbed with tools. By making the outer cover multi-functional, the patent avoids adding excessive complexity while achieving enhanced security.

AI summary
A steering column lock comprises a bearing-mounted, free-rotating keyhole cover that covers an underlying locking device. When installed on the steering column of a vehicle, the steering column lock prevents a would-be car thief from grabbing the lock with pliers or another tool and using the lock to turn the steering column and thus drive the vehicle, because rotation of the free-rotating outer cover does not cause rotation of the other portions of the lock.
