Twistgrip Steering Cable Linkage for Human-Powered Vehicle Maneuverability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems lack an efficient and integrated steering and driving mechanism that allows for easy maneuverability and propulsion, particularly in human-powered vehicles.
Innovation Solution
A vehicle system incorporating a drivable wheel actuated by a driving actuator and a steerable wheel actuated by a steering actuator, both coupled to the vehicle frame, allowing for independent control of steering and driving through a novel steering system utilizing a cable linkage between the steering handle and the steerable wheel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate steering mechanism is added to a vehicle, then steering control is improved, but device complexity increases
Solution Approach 1:
The steering actuator is integrated with the driving actuator to form a combined actuator assembly. The cable linkage system merges the steering control function with the existing driving mechanism, allowing both steering and driving operations to be coordinated through a unified structural arrangement rather than completely separate systems.
Solution Approach 2:
The handle assembly serves multiple functions: it provides both steering control through cable linkage and driving actuation through the integrated driving actuator. This multi-functional design eliminates the need for completely separate steering and driving mechanisms, reducing overall system complexity while maintaining independent control capabilities.
2Productivity
If an integrated driving system is implemented, then propulsion efficiency is improved, but ease of manufacture deteriorates
Solution Approach 1:
The integrated actuator assembly is divided into modular components including the steering actuator, driving actuator, and cable linkage segments. This segmentation allows each component to be manufactured separately using standard fabrication processes, then assembled into the integrated system, balancing manufacturing ease with functional integration.
Solution Approach 2:
The cable linkage acts as an intermediary element that connects the steering and driving actuators to their respective wheels. This intermediary mechanism allows the integrated system to be constructed from separate, easily manufactured components while achieving coordinated propulsion and steering functions through the cable transmission system.

AI summary
A steering system and/or a driving system and/or a vehicle including one or more thereof, whereby the driving system can include a drivable wheel coupled to a frame of the vehicle and actuated by a driving actuator, and the steering system can include a steerable wheel coupled to the frame of the vehicle and actuated by a steering actuator. The vehicle can be configured as a human-powered vehicle, which may be similar to a bicycle, tricycle, quadricycle, wheelchair, or the like.
