Shift Cable Anti-Theft Cover for Vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-theft devices for vehicles, such as electric steering column locks, are complex and costly, and do not adequately prevent theft when the shift lever is manipulated by removing the shift cable, as they can be bypassed by exposing and pulling the shift cable.
Innovation Solution
An anti-theft device featuring an approach prevention cover integrated into the shift lever housing, which covers the shift cable and uses a shear bolt and guide plate system to secure the cover in place, preventing removal of the shift cable and thus preventing vehicle theft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an electric steering column lock (ESCL) is used to prevent vehicle theft, then the steering wheel is locked and theft is prevented, but the device has a large number of components and complicated structure, increasing production cost and vehicle weight
Solution Approach 1:
The patent extracts and eliminates the complex electric steering column lock system, replacing it with a simple mechanical cover structure that performs the same theft prevention function without the need for motors, sensors, or control systems
Solution Approach 2:
The patent uses a simple disposable-style cover structure that can be easily manufactured and replaced, rather than a complex expensive electronic locking system, reducing production costs while maintaining theft prevention capability
2Reliability
If the shift lever is locked by a separate locking means to prevent movement, then the shift lever cannot be moved, but theft can still occur by removing the console, exposing the shift cable, and pulling the removed shift cable to shift from P-stage to N-stage
Solution Approach 1:
The patent applies preliminary anti-action by providing a cover structure that prevents the shift cable from being accessed or removed in the first place, stopping the theft process before it can begin rather than just locking the shift lever position
Solution Approach 2:
The patent uses a nested structure where the cover is disposed within the shift lever housing, creating layers of protection that prevent access to the shift cable while maintaining a compact integrated design
3Device complexity
If a simple cover structure is used to protect the shift cable, then the structure is simplified and production cost is reduced, but the cover must still be securely fastened to prevent removal
Solution Approach 1:
The patent uses preliminary action by providing pre-formed engagement protrusions on the cover and corresponding engagement grooves in the housing, allowing for simple yet secure attachment without requiring complex fastening mechanisms
Solution Approach 2:
The patent merges the cover structure with the housing through direct integration features, combining two separate components into a unified assembly that is both simple to manufacture and secure in attachment

AI summary
An anti-theft device for a vehicle includes an approach prevention cover disposed in a shift lever housing to cover a shift cable connected to a shift lever so as to prevent the shift cable from being detached. Such an anti-theft vehicle makes is possible to easily and efficiently prevent theft of the vehicle by preventing a shift cable operated along with operation of a shift lever from being removed.
