Rotating Lock Arm Mechanism for Cylindrical Pole Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cylindrical objects such as fishing rods, poles, and bars lack secure attachment points, making it difficult to secure them using traditional locks or security cables, and there is no device available that can attach to these items without modification, provide a secure attachment point, and lock multiple similar items together.
Innovation Solution
A locking device comprising a first lock arm and a second lock arm, a pin, and a lever, where the first lock arm is rotatably coupled to the second lock arm, and the lever is rotatably coupled to the pin, allowing the device to be adjusted to fit various diameters and create a secure attachment point for locks or security cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional locks or security cables are used, then security is provided, but cylindrical objects lacking attachment points cannot be secured
Solution Approach 1:
The locking device acts as an intermediary between the cylindrical object and the security cable/lock. It attaches to the cylindrical surface without modification and provides a retaining ring that accepts the security cable, thereby enabling security for objects that originally lacked attachment points
Solution Approach 2:
The locking device is designed with adjustable lock arms and a rotating lever mechanism that can accommodate various diameters of cylindrical objects. This universal design allows a single device to secure different types of cylindrical items (poles, rods, handles, bars) without requiring object-specific modifications
2Adaptability or versatility
If the locking device is designed to fit various diameters, then adaptability is improved, but device complexity increases
Solution Approach 1:
The lock arms are designed to be movable and adjustable rather than fixed. The first and second lock arms can rotate and adjust their positions, allowing the device to adapt to different cylindrical diameters. The lever's rotation between unlocked and locked states also provides dynamic adjustment capability
Solution Approach 2:
The locking device is divided into separate functional components: first lock arm, second lock arm, pin, and lever. This segmentation allows each component to be optimized independently and facilitates adjustment mechanisms that can accommodate various sizes without requiring a completely different device for each diameter
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 locking device effectively secures cylindrical objects by creating a secure attachment point without modifying the item, allowing multiple similar items to be locked together, thereby enhancing the security of items like fishing rods and poles.
Implementation Method 1
a first lock arm having a retaining ring and a second lock arm, the first lock arm rotatably coupled to the second lock arm
Implementation Method 2
a pin, the pin rotatably coupled to the second lock arm
Implementation Method 3
a lever having a first end and a second end, the first end of the lever rotatably coupled to the pin; and where in an unlocked state the second end of the lever is external to the retaining ring and in a locked state the second end of the lever is within the retaining ring
