Grooved Bolt Axial Locking Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bolt securing devices with grooves are either complex to manufacture, prone to damage during assembly and disassembly, or have holding and spring forces that cannot be independently selected, leading to inadequate security and reliability.
Innovation Solution
A simple and reliable arrangement featuring a securing part that engages in opposite regions of the groove, with a separate element that fixes and holds the securing part in place, allowing easy assembly and disassembly, and optionally providing anti-loss and protective functions through distinct design configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single integrated securing device is used, then manufacturing is simpler, but the holding force and spring force cannot be independently selected
Solution Approach 1:
The securing device is divided into two separate components: a securing part that engages with the groove and an element that provides holding force. This segmentation allows the holding force (via the element) and spring force (via the securing part) to be independently selected and optimized, while still being manufactured through simple processes
2Reliability
If high spring force is applied for secure locking, then reliability improves, but the securing part becomes damaged or bent during disassembly
Solution Approach 1:
By separating the spring force function (securing part) from the holding force function (element), the design allows the element to provide the primary holding force, enabling the securing part to use lower spring force that is sufficient for engagement but not high enough to cause damage during disassembly
Solution Approach 2:
The element acts as an intermediary that absorbs and provides the holding force, allowing the securing part to engage and disengage more easily without bearing the full force load, thus preventing damage while maintaining reliability
3Reliability
If the securing part is held firmly in the groove, then axial security improves, but assembly and disassembly becomes difficult
Solution Approach 1:
The securing device is segmented into a securing part for engagement and an element for holding, where the element can be designed with specific geometric features that provide strong axial security while allowing controlled movement for assembly and disassembly
Solution Approach 2:
The element is designed to be displaceable relative to the securing part, allowing dynamic adjustment during assembly and disassembly operations while maintaining firm holding in the secured position, thus balancing security with operational ease
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 solution ensures secure and reliable axial locking of bolts with easy assembly and disassembly, while minimizing complex machining and avoiding damage to the securing part, thereby enhancing the overall security and usability of the bolt securing device.
Implementation Method 1
a securing part which engages in a securing position in the groove in at least opposite regions of the groove and is held there in the securing position by the element

AI summary
The invention relates to an arrangement for axially securing a bolt (2, 102, 202, 302) provided with a groove (5, 105, 205, 305) by means of a locking element (3, 103, 203, 303) which engages in the groove (5, 105, 205, 305) in a locking position at least on opposite areas of the groove and is held there in the locking position. In order to create an arrangement for the axial securing of a bolt provided with a groove, which is simple in design and reliable, it is proposed that the arrangement further comprises a separate element (4, 104, 204, 304) that extends axially through the bolt and is fixed by the securing element (3, 103, 203, 303) in the locking position at the level of the groove (5, 105, 205, 305) and that at least partially surrounds the securing element (3, 103, 203, 303) in the locking position.
