Anti-rotation Device for Vehicle Lock Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lock systems for vehicles, such as glove compartment configurations, face challenges with complex and costly designs, misalignment issues, and poor operating feel due to numerous components, leading to increased production and installation complexity and actuation delays.
Innovation Solution
An anti-rotation device with a base cover unit, rotor, and interlock system that provides haptic feedback for precise alignment and installation of the lock system, using a radial rib structure and interlock points or waves to ensure correct positioning without additional tools, and is made from lightweight materials like glass fiber reinforced polymers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a transmission mechanism is added to enable locking and unlocking actions, then the lock system becomes functional, but the device complexity increases and production costs rise
Solution Approach 1:
The patent combines the anti-rotation function and alignment function into a single integrated device that is directly mounted on the lock cylinder. The device merges the rotor, base cover unit, and interlock system into one compact assembly, eliminating the need for separate transmission mechanisms while maintaining full locking and unlocking functionality.
Solution Approach 2:
The invention extracts the alignment and anti-rotation control functions from the complex transmission mechanism and places them directly on the lock cylinder body. By taking out these specific functions and implementing them through the interlock system and radial rib structure, the patent simplifies the overall device while preserving essential locking operations.
2Reliability
If multiple components are used in the transmission mechanism, then the locking function is achieved, but the manufacturing cost increases
Solution Approach 1:
The patent merges multiple functions (alignment, anti-rotation, locking indication) into a single integrated device mounted directly on the lock cylinder. This consolidation reduces the total component count and simplifies manufacturing processes, thereby lowering production costs while maintaining reliable locking functionality.
Solution Approach 2:
The device uses the rotational movement of the lock cylinder itself to activate the interlock system and generate haptic feedback, rather than requiring separate actuating mechanisms. The lock cylinder's own motion serves to engage the radial rib structure with the interlock points, eliminating the need for additional actuation components and reducing manufacturing complexity.
3Reliability
If a complex transmission mechanism is used, then the lock system is functional, but the actuation speed decreases and operating feel deteriorates
Solution Approach 1:
The patent extracts the essential locking function from the complex transmission mechanism and implements it through a direct connection to the lock cylinder. By removing intermediate transmission components, the actuating force is transferred immediately without delay, improving actuation speed and providing a more responsive operating feel.
Solution Approach 2:
The device merges the anti-rotation control and locking activation into a single direct-action mechanism. The rotor's rotation directly engages the interlock system, which in turn directly actuates the locking mechanism, eliminating multiple transmission stages and improving response time while maintaining reliable locking capability.
4Adaptability or versatility
If the cylinder lock is attached separately from the operating handle, then the lock system is modular, but misalignment occurs between the cylinder lock and operating handle
Solution Approach 1:
The patent incorporates an interlock system with radial rib structure that provides haptic feedback during the insertion and rotation of the lock cylinder. This feedback mechanism guides the installer to achieve precise alignment between the cylinder lock and operating handle, ensuring correct positioning even though the components are attached separately. The haptic feedback confirms when proper alignment is reached.

AI summary
The present disclosure shows an anti-rotation device for a lock system in a motor vehicle, comprising a base cover unit having an opening for passage of a lock system; a cover unit; a rotor rotatably attached to a back side of the base cover unit by a latch mechanism, in which the rotor has a radial rib structure; a hollow receiving body accommodating the rotor and having a recess; and an interlock system on a circumferential line of the recess of the receiving body. On rotation of the rotor in the receiving body the position of the rotor in the receiving body is ascertained by the contact of the interlock system with the rib structure.
