Adjustable Electric Bike with Dynamic Component Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional bicycles are inflexible, causing strain and balance issues for individuals with back and knee injuries, as well as older adults, leading to increased cycling accidents, as they require a fixed position to propel the bike, which can be difficult to maintain.
Innovation Solution
An adjustable electric bicycle with mechanisms to alter the position of the handlebar, saddle, and pedal unit, allowing manual or programmed adjustments via a smartphone app, featuring a generator-powered system that disconnects the chain and uses a motor to drive the rear wheel, enabling flexible positioning and reduced strain through variable pedal angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional bicycles use fixed components, then the structure is simple and easy to manufacture, but the adaptability to different users and conditions is poor
Solution Approach 1:
The patent implements adjustable components including an adjustable saddle position, adjustable handlebar position, and adjustable pedal arm length. These dynamic elements allow the bicycle to adapt to different user body dimensions and riding conditions, directly resolving the contradiction between adaptability and structural complexity by introducing controlled variability to key components.
Solution Approach 2:
The invention changes physical parameters of the bicycle components - the saddle can move along the seat tube, the handlebar can be repositioned on the stem, and the pedal arm length can be adjusted. These parameter changes enable the same bicycle structure to serve multiple users with different physical characteristics, improving adaptability without requiring multiple complete bicycles.
2Object-affected harmful factors
If the pedal arm length is fixed, then the mechanical structure is simple, but the strain on user's back and knees cannot be reduced for users with injuries
Solution Approach 1:
The patent specifically addresses the pedal mechanism by making the pedal arm length adjustable. Users with back or knee injuries can modify the pedal arm length to reduce the mechanical strain on their bodies during pedaling, directly addressing the harmful factors while accepting increased mechanical complexity in the pedal assembly.
3Ease of operation
If the saddle and handlebar positions are fixed, then the bike structure is stable and simple, but older adults have difficulty maintaining balance when starting or stopping
Solution Approach 1:
The patent makes both the saddle position and handlebar position adjustable to help older adults maintain better balance. By allowing these components to be repositioned, users can optimize their riding posture for stability, particularly when starting or stopping, thereby improving ease of operation despite the added adjustment mechanisms.
4Adaptability or versatility
If the bicycle components are fixed in position, then the manufacturing cost is lower, but the cyclist cannot adjust to different riding conditions and moments
Solution Approach 1:
The patent implements multiple adjustable components including saddle position, handlebar position, and pedal arm length that can be modified during different moments of the ride. This dynamic adjustability allows cyclists to adapt to varying riding conditions and personal comfort needs, directly addressing the adaptability requirement while accepting increased manufacturing complexity.
