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

VSEngineering 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

Engineering Contradiction:
Improveadjustability of riser bar lengthVSAvoidcomplexity of telescopic mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of manufacture

If the collet is exposed, then the structure is simple, but the appearance is compromised and inadvertent adjustment may occur

Engineering Contradiction:
Improvesimplicity of structureVSAvoidaesthetic appearance
Core Design Contradiction:
Ease of manufactureVSShape

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

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.
