Inline Wheeled Truck Tilting Steering Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rigid in-line wheel systems do not allow for sharper, cleaner turns, limiting the maneuverability of inline wheeled devices.
Innovation Solution
A set of two wide inline wheels connected to a truck assembly with a specific configuration of elongated brackets, cross platform, base platform, and support members that allow for tilting pressure to steer the device, enabling sharper turns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rigid in-line wheel system is used, then structural stability is maintained, but turning sharpness and maneuverability deteriorate
Solution Approach 1:
The wheel system is divided into separate modular components: individual wheels, elongated brackets, support members, and a base platform. Each component can be independently manufactured and assembled, allowing the rigid structure to be segmented into functional units that facilitate turning mechanisms while maintaining overall structural stability.
Solution Approach 2:
The patent introduces dynamic elements to the otherwise rigid structure, including pivoting mechanisms at the connection points between wheels and brackets, and adjustable support members. These dynamic components enable the wheels to turn sharply by allowing relative motion between parts, while the main structural framework remains rigid for stability.
2Ease of operation
If tilting pressure mechanism is added to enable sharp turns, then maneuverability improves, but device complexity increases
Solution Approach 1:
The patent employs flexible resin bushings as pivot points within the truck assembly. These flexible elements allow the support members and brackets to tilt and pivot under applied pressure, enabling sharp turns and improved maneuverability. The flexible bushings provide the necessary compliance and motion capability without requiring complex mechanical linkages or additional actuation systems.

AI summary
An inline wheeled truck is a structural arrangement for wheels on a skating device. The inline wheeled truck includes a first wheel, a second wheel, a left elongated bracket, a right elongated bracket, a cross platform, a base platform, a first support member, and a second support member. The first wheel and the second wheel allows the inline wheeled truck to roll in a forward direction and a backward direction. The left elongated bracket and the right elongated bracket evenly space and structurally secure the first wheel and the second wheel. The cross platform structurally bridges the left elongated bracket and the right elongated bracket. The first support member and the second support member are connected in between the cross platform and the base platform and convert a tilting motion of the base platform into a steering motion of the cross platform.
