Indoor Bicycle Adjustable Frame for Outdoor Dimension Replication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stationary bicycles lack the ability to be adjusted in sufficient dimensions to replicate the dimensional relationships found in outdoor bicycles, leading to an uncomfortable riding experience and poor fit for riders with varying anatomical dimensions.
Innovation Solution
A stationary indoor 'smart' training bicycle with adjustable components that allow for customizable frame dimensions, including a vertically adjustable center post, horizontally adjustable arms for the seat and handlebars, and an adjustable crank arm, enabling the bicycle to be tailored to fit individual riders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional exercise bicycles use a fixed rigid frame design, then structural stability is improved, but adaptability to different rider dimensions deteriorates
Solution Approach 1:
The patent applies dynamics by making the bicycle frame adjustable rather than fixed. The frame includes adjustable components such as the seat post, handlebars, and crank arms that can be modified to match different rider anatomical dimensions. This allows the same frame structure to adapt to various riders while maintaining stability through proper adjustment and locking mechanisms.
Solution Approach 2:
The patent implements parameter changes by allowing modification of key frame dimensions including seat height, handlebar position, and crank arm length. These parameters can be adjusted to replicate the dimensional relationships of outdoor bicycles, enabling the stationary bike to accommodate different rider sizes and preferences while preserving structural integrity.
2Device complexity
If stationary bicycles have limited adjustment options, then device complexity is reduced, but ability to replicate outdoor bicycle dimensional relationships deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the frame into multiple independently adjustable segments. Rather than adjusting the entire frame as one unit, specific components such as the seat post, handlebars, and crank arms can be adjusted separately. This modular approach allows comprehensive dimensional customization without requiring complex integrated adjustment mechanisms.
Solution Approach 2:
The patent implements universality by designing adjustment mechanisms that can replicate multiple dimensional relationships found in various outdoor bicycle configurations. The same adjustment system can accommodate different frame geometries, seat positions, and handlebar setups, making the stationary bicycle universally adaptable to numerous riding styles and anatomical requirements.
3Ease of operation
If professional bike fit services are used, then riding comfort and injury prevention are improved, but cost and portability deteriorate
Solution Approach 1:
The patent applies self-service by enabling riders to perform their own bike fit adjustments without requiring professional services. The adjustable frame components allow riders to modify seat height, handlebar position, and crank arm length based on their anatomical dimensions and comfort preferences. This empowers users to achieve proper fit independently, eliminating the need for expensive and non-portable professional fitting services.

AI summary
A stationary indoor "smart" training bicycle includes a unique combination of adjustable components to provide configurable dimensions to adjust the frame size of the indoor bicycle to properly fit a rider. A system is also provided to process a digital image of an outdoor bicycle and determine and translate dimensions and adjustments to the indoor bicycle to match one or more dimensions (lengths, angles, separations, etc.) of the outdoor bicycle.
