Auxiliary Handle Assembly for Exercise Bikes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Exercise bike handles often have slippery foam sleeves that can cause users to lose grip, especially when sweaty, and may not simulate the feel of a bicycle handlebar for users accustomed to gripping bicycle handlebars.
Innovation Solution
An auxiliary handle assembly with an L-shaped extension handle featuring a grip made of rubber, connected via clamps and positioning units with resilient members and beads, allowing adjustable angles and secure mounting to the exercise bike handlebar, and accommodating a water bottle frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a foam sleeve is used on the handle, then the handle provides cushioning comfort, but the grip becomes slippery when users sweat
Solution Approach 1:
The patent changes the material parameter of the handle surface from foam to rubber, which has different friction characteristics. The rubber material maintains grip security even when sweaty, as it provides better friction coefficients and does not become excessively slippery under moisture conditions compared to foam material.
Solution Approach 2:
The patent uses a composite structure combining rubber material with the handle bar, creating a multi-material system that leverages the superior grip properties of rubber while maintaining the structural integrity of the handle. This composite approach resolves the slipping issue by introducing a material with complementary friction characteristics.
2Adaptability or versatility
If a fixed handlebar design is used, then the structure is simple, but it cannot accommodate users accustomed to bicycle handlebar gripping
Solution Approach 1:
The patent introduces an adjustable angle mechanism that allows the extension handle to rotate and lock at different angles, transforming a static fixed handlebar into a dynamic adjustable one. This enables the handle to simulate bicycle handlebar positions, accommodating users accustomed to bicycle gripping styles while maintaining reasonable structural complexity through standardized adjustment mechanisms.
Solution Approach 2:
The extension handle assembly serves multiple functions: it extends the reach of the handlebar, provides adjustable angular positioning to simulate bicycle handlebars, and maintains structural support. This multi-functionality addresses the adaptability requirement without proportionally increasing complexity, as each function is integrated into a unified assembly.
3Ease of operation
If an extension handle is added to simulate bicycle handlebar, then user comfort is improved, but the device complexity increases
Solution Approach 1:
The patent divides the handle assembly into separate modular components: the extension handle section, the clamping mechanism, the positioning units, and the mounting interface. This segmentation allows each component to be optimized independently for comfort and functionality while simplifying assembly and maintenance, thereby managing overall device complexity through modularity.
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
Provides a secure, adjustable grip that mimics a bicycle handlebar, preventing slipping and allowing users to comfortably operate the exercise bike with improved grip security and versatility.
Implementation Method 1
Two first positioning units (500) each include a first resilient member (510) and a first bead (520). The first resilient members (510) are respectively located in the two first recesses (212) and bias the two first beads (520).
