Riser bar assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing riser bar assemblies lack the ability to adjust length, limiting user height adjustment and requiring new fixture points, which can lead to unnecessary damage during retrofitting in ablutionary settings.
Innovation Solution
A telescopic riser bar assembly with a collet system and a sleeve that allows adjustable length by sliding bar elements and secures positions, while the sleeve covers the collet to prevent inadvertent adjustments and enhance aesthetics.
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 reliable, but the user cannot adjust the height and new fixture points are required for different heights
Solution Approach 1:
The riser bar assembly is divided into multiple telescopic bar elements (first bar element, second bar element) that can slide relative to each other. This segmentation allows the overall length to be adjusted by extending or retracting the bar elements, providing height adaptability while maintaining a relatively simple structural concept.
Solution Approach 2:
The riser bar assembly transitions from a fixed structure to a dynamic, adjustable structure through the telescopic mechanism. The bar elements can move relative to each other to change the length, and the collet mechanism allows for quick locking and unlocking to fix or adjust the position, enabling dynamic adaptation to different height requirements.
2Ease of operation
If the collet is exposed, then the adjustment mechanism is accessible, but inadvertent adjustments occur and aesthetics are compromised
Solution Approach 1:
A decorative sleeve is introduced as an intermediary component between the user and the collet mechanism. The sleeve covers the collet to prevent accidental adjustments and improve aesthetics, while still allowing intentional adjustments by providing access points or mechanisms (such as removing the sleeve or using a tool through the sleeve) to operate the collet when needed.
3Adaptability or versatility
If a telescopic mechanism is added to allow height adjustment, then user experience improves, but the device complexity increases
Solution Approach 1:
The telescopic mechanism uses a nested doll principle where one bar element is inserted within another bar element. This allows the riser bar to extend or retract by sliding the inner bar relative to the outer bar, achieving length adjustment in a compact and relatively simple manner compared to other telescopic mechanisms.
4Ease of manufacture
If the riser bar assembly is made adjustable, then retrofitting becomes possible without damaging structures, but the manufacturing complexity increases
Solution Approach 1:
The riser bar assembly is designed with pre-configured telescopic bar elements and collet mechanisms that allow for easy adjustment to different lengths before installation. This preliminary configuration enables the assembly to be adapted to existing fixture points without requiring on-site modification or damage to structures, facilitating retrofittability.

Function Achieved in This Case
Enables adaptable height adjustment and retrofitting without damaging existing structures, improving user experience and reducing installation costs by allowing the reuse of previous fixture points.
Implementation Method 1
a collet configured such that relative positions of the first bar element and the second bar element can be fixed by tightening the collet
Implementation Method 2
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

AI summary
A riser bar assembly is provided for use in an ablutionary setting. An adjustable riser bar has a telescopic arrangement, and includes 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.
