Adaptive Tricycle Dynamic Stabilization for Therapeutic Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art tricycles used in a therapeutic capacity tend to tip when the rider turns, posing a significant risk, especially for individuals with motor impairments who may be unable to protect themselves during a fall.
Innovation Solution
A multi-wheel tricycle design featuring a suspension-mounted wheelie bar, steering lock-out system, dynamic stabilization system with a dual wishbone lever system, optimized rider positioning, shock-absorbing scheme, and improved chain management system to enhance stability and allow for various maneuvers like rapid cornering and wheelies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional tricycle design is used for therapeutic purposes, then it provides basic mobility for disabled individuals, but it tips when the rider turns causing safety risks
Solution Approach 1:
The patent implements a dynamic stabilization system with dual wishbone levers that actively adjust during turns to maintain stability. The system allows controlled pivoting motion while preventing excessive tipping, transforming the static stability problem into a dynamically controlled solution that adapts to turning movements.
Solution Approach 2:
The patent changes the stability parameters by introducing a wheelie bar with specific geometry and positioning, and by configuring the dual wishbone lever system with adjustable arms. These parameter changes allow the tricycle to maintain stable pitch angles during turns while enabling therapeutic maneuvers.
2Productivity
If the tricycle allows rapid cornering and wheelies for therapeutic exercise, then it provides physical stimulus and health benefits, but it increases the risk of tipping and falls
Solution Approach 1:
The patent incorporates a shock-absorbing scheme with suspension elements that cushion impacts and reduce the severity of potential falls. This beforehand cushioning protects riders with motor impairments who may be unable to protect themselves during unexpected tipping or falls.
Solution Approach 2:
The dual wishbone lever system acts as an intermediary between the rider's maneuvers and the tricycle's stability. It mediates the forces generated during rapid cornering and wheelies, allowing therapeutic exercise while preventing harmful tipping through controlled mechanical intervention.
3Ease of manufacture
If the tricycle design is simplified for ease of manufacture, then production cost decreases, but it lacks the complex stabilization systems needed for safety
Solution Approach 1:
The patent segments the stabilization function into distinct modular components: a wheelie bar assembly, a dual wishbone lever system, and a shock-absorbing scheme. This segmentation allows each component to be manufactured separately using standard fabrication processes, then assembled into the complete safety system, balancing manufacturing simplicity with functional complexity.
