Adjustable Locking Assembly for Play-Free Vibration Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking devices for connecting assemblies together often fail to provide a reliable, firm, and vibration-proof hold due to mechanical manufacturing tolerances and play in the connection.
Innovation Solution
The locking device features an adjustable adjustment element on the first locking part that can be moved between a first position for closing and a second position to block opening, ensuring a robust mechanical or mechanical-magnetic connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical locking connection is used to connect two assemblies, then the connection provides basic holding capability, but mechanical manufacturing tolerances create play and reduce reliability in the connection
Solution Approach 1:
The patent applies parameter changes by introducing an adjustment element that can be positioned at multiple discrete locations along the slot. This allows the locking device to compensate for manufacturing tolerances by adjusting the engagement position, thereby maintaining reliable connection despite variations in manufacturing precision.
Solution Approach 2:
The patent implements dynamics by making the adjustment element movable between different positions within the slot. This dynamic capability allows the locking mechanism to adapt to different assembly configurations and tolerate manufacturing variations, improving connection reliability without requiring high manufacturing precision.
2Reliability
If an adjustment element with multiple positions is introduced to compensate for tolerances, then connection reliability improves, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the adjustment element into discrete positional states corresponding to different engagement positions. This segmentation allows the complex function of tolerance compensation to be achieved through simple, distinct positions rather than continuous adjustment, reducing overall device complexity while maintaining reliability.
Solution Approach 2:
The adjustment element serves as an intermediary between the first and second locking parts, mediating the connection by providing multiple engagement positions. This intermediary component absorbs the complexity of tolerance compensation, allowing the main locking mechanism to remain simple while achieving reliable connection.
3Reliability
If the adjustment element is made adjustable between multiple positions, then the locking device can compensate for play and create a firm connection, but the ease of operation decreases due to additional adjustment steps
Solution Approach 1:
The patent applies preliminary action by pre-positioning the adjustment element in optimal engagement positions before final locking. This allows the firm connection to be achieved without requiring complex real-time adjustments during operation, as the adjustment element is already configured for optimal engagement.
Solution Approach 2:
The adjustment element provides self-service by automatically positioning itself or being easily positioned into the correct engagement state during the locking process. This self-positioning capability reduces the operational complexity for the user while maintaining the firm connection benefits of multiple adjustment positions.

AI summary
A locking device for connecting two assemblies to one another includes a first locking part which is associated with a first one of the assemblies and a housing part and two slots each having at least one first engagement protrusion, wherein at least one of the slots includes an adjustment element which can be adjusted relative to the housing part. The locking device also includes a second locking part which is associated with a second one of the assemblies and comprises two engagement elements each with at least one second engagement protrusion. The adjustment element is arranged on the housing part of the first locking part so as to be adjustable between a first position and a second position.
