Cylinder Mounting With Angled Guides for Single-Installer Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for attaching devices, such as validators, to cylindrical elements in passenger transport vehicles are complex due to varying diameters and require multiple installers to secure the mount, especially when dealing with additional cables.
Innovation Solution
A holder with a base body and carriage design, featuring angled guide elements, allows for a single installer to clamp the device by relative movement, eliminating the need for adapter sleeves and simplifying the attachment process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a standard bracket with adapter sleeves is used to attach devices to cylinder elements, then the bracket can accommodate different diameters, but the attachment process requires multiple installers and becomes significantly complicated
Solution Approach 1:
The bracket is divided into two separate components: a base body that attaches to the cylinder element and a carriage that holds the device. This segmentation allows the base body to remain simple and adapter-free while the carriage provides the necessary adaptability through its engagement mechanism with the base body's guide elements.
Solution Approach 2:
The carriage is designed to be self-positioning on the cylinder element through its guide elements engaging with the base body's guide elements. The relative movement between carriage and base body automatically adjusts the effective holder diameter to match the cylinder element diameter, eliminating the need for manual adapter selection and installation.
2Adaptability or versatility
If adapter sleeves are positioned between the contact surfaces and the cylinder element to accommodate smaller diameters, then the bracket fits different sizes, but additional cables must be led through the adapter sleeves and base body increasing complexity
Solution Approach 1:
The adapter sleeve component is completely removed from the system. Instead of using adapter sleeves to accommodate different diameters, the invention uses the engagement between the carriage guide elements and base body guide elements to automatically adjust the holder's effective diameter, thereby eliminating the cable routing complexity associated with adapters.
3Adaptability or versatility
If the holder diameter is reduced to fit smaller cylinder elements, then the bracket accommodates various sizes, but the structural integrity and stability against vibrations may be compromised
Solution Approach 1:
The holder transitions from a static fixed-diameter structure to a dynamic adjustable-diameter structure. The carriage can engage with the base body at different positions along the guide elements, allowing the effective holder diameter to dynamically adapt to the cylinder element size while maintaining structural integrity through the rigid guide element engagement.
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
Enables secure and efficient attachment of devices like validators to cylindrical elements with diameters between 28 mm and 45 mm by a single installer, reducing complexity and ensuring stability against vibrations.
Implementation Method 1
The base body guide elements and carriage guide elements are tilted relative to the base body contact surface and carriage contact surface, respectively, by a base body angle of between 1° and 25° and by a carriage angle of between 1° and 25°. A first relative movement of the carriage to the base body causes a reduction in an effective holder diameter, thus causing a self-locking clamping of the holder to the cylinder element.
