Telescopic Riser Bar Assembly with Collet-Based Length Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing riser bar assemblies lack the ability to adjust length, making them inflexible for varying user preferences and environmental constraints, and often require unnecessary damage to existing fixtures during retrofitting.
Innovation Solution
A telescopic riser bar assembly with a collet system and a sleeve that allows adjustable length by sliding the first bar element relative to the second bar element, with the collet being hidden by the sleeve for aesthetic and functional purposes, enabling secure fixing and attachment to surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-length riser bar assembly is used, then the structure is simple and easy to manufacture, but it cannot adapt to varying user preferences and environmental constraints
Solution Approach 1:
The riser bar assembly is divided into multiple bar elements (first bar element, second bar element) that can be segmented and reconfigured. The collet mechanism divides the assembly into adjustable segments that can be independently positioned, allowing the overall length to be customized while maintaining structural integrity through the collet securing mechanism.
Solution Approach 2:
The telescopic arrangement employs a nested structure where the first bar element and second bar element are positioned one within the other along the longitudinal axis. The collet fits over these bar elements to secure them in place, creating a compact nested configuration that enables length adjustment while maintaining a space-efficient design.
2Ease of manufacture
If the collet is exposed, then the structure is simple, but the appearance is compromised and inadvertent adjustment may occur
Solution Approach 1:
The sleeve acts as an intermediary component that covers the collet and bar elements. This intermediate covering element provides a smooth, continuous surface that improves the aesthetic appearance by hiding the mechanical adjustment components, while the sleeve itself can be manufactured as a simple cylindrical shape that does not significantly complicate the overall structure.
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 telescopic design allows for customizable height adjustment and secure attachment to surfaces, preventing damage to existing fixtures and enhancing the assembly's appearance and functionality.
Implementation Method 1
The collet is configured such that the first bar element is secured to the second bar element by the collet

AI summary
A riser bar assembly, for use in an ablutionary setting, having an adjustable riser bar with a telescopic arrangement comprising: a first bar element; a second bar element, translatable relative to the first bar element along a length of the first bar element; and a collet configured such that relative positions of the first bar element and the second bar element can be fixed by tightening the collet.
